Leaving your boat afloat all year round is a practical choice for many boaters who want to enjoy their boat at any time. Unlike wintering on land, this solution allows immediate availability and avoids handling costs. However, this convenience comes with special maintenance requirements that should not be overlooked. The marine environment in fact exerts a permanent effect on the hull, equipment and embedded systems, creating specific challenges that do not exist during dry storage. Constant humidity, the action of marine organisms, accelerated corrosion and mechanical stresses related to boat movements require regular monitoring and appropriate preventive interventions. Understanding these issues and setting up a structured maintenance program makes it possible to preserve the value of your investment, to ensure your safety and that of your passengers, while significantly extending the life of your boat.
Why is specific maintenance necessary for a boat that stays afloat?
The permanent maintenance of a boat in the water creates conditions of use and wear that are very different from those of wintering on land. This particular situation imposes ongoing constraints that justify a specifically adapted maintenance approach.
The risks associated with prolonged immobilization
When a boat stays afloat without regular navigation, it undergoes a form of immobilization that can be as harmful as intensive use. Mechanical systems that don't work regularly tend to seize up or deteriorate prematurely. The engine, in particular, suffers from the absence of frequent starts that would allow the moisture accumulated in the circuits to be evacuated and the lubrication of the moving parts to be maintained. Joints can harden, hoses lose flexibility, and hydraulic systems can develop obstructions. Electronic equipment, on the other hand, is particularly sensitive to ambient humidity, which favors the oxidation of connections and can lead to insidious malfunctions that are only revealed when they are put back into service.
The effects of the marine environment on the hull and equipment
Seawater is a particularly aggressive environment for all materials that make up a boat. Salinity considerably accelerates corrosion phenomena on metal parts, whether they are stainless steel fittings, aluminum equipment or bronze parts. Temperature variations between day and night create cycles of expansion and contraction that stress joints and assemblies. The mechanical action of waves and choppy, even moderate in a port, generates repeated stresses on the entire structure. The shell itself, permanently submerged, becomes the support for the development of a multitude of marine organisms that form what is called biological fouling. This gradual colonization not only alters the aesthetics of the boat but also degrades its hydrodynamic performances and may, in the long run, damage protective coatings such as antifouling or gelcoat.
The challenges of safety and sustainability
Insufficient maintenance of a boat that stays afloat can quickly compromise the safety of those on board. A mooring that gives way during a storm, a leaking hull valve, an electrical circuit that causes a fire to start or a hull weakened by osmosis represent all potentially serious risks. Beyond the immediate safety aspect, the sustainability of the investment that a boat represents depends directly on the quality of maintenance monitoring. A well-maintained boat maintains its market value and can be used for several decades, while a neglected boat can see its value drop drastically in just a few years. Curative repairs are always more expensive than preventive maintenance, and certain damages such as advanced osmosis may require heavy and expensive interventions that sometimes exceed the owner's budget.
Regular inspection of the hull and the living works
The hull and the submerged parts of the boat are the first line of defence against the marine environment and deserve particular attention in a maintenance program for a boat that stays afloat.
Checking the condition of the antifouling
Antifouling represents the essential protection against the colonization of the hull by marine organisms. This special paint contains biocides that are released gradually to prevent algae, shells, and other organisms from settling in. For a boat that remains permanently submerged, the effectiveness of antifouling decreases over time at a rate that depends on the quality of the product used, the temperature of the water and the local biological activity. A regular visual inspection reveals the appearance of the first dirt, a sign that the protection is beginning to weaken. The most exposed areas, such as the waterline or appendages, may show signs of colonization before the rest of the shell. It is also important to check the adhesion of the antifouling itself, as a product that peels off or blisters loses its effectiveness and requires corrective treatment before greater damage to the underlying gelcoat occurs.
Corrosion and sacrificial anodes control
Electrolytic corrosion is a permanent threat to the submerged metal parts of a boat. To prevent this, sacrificial anodes made of zinc, aluminum or magnesium are installed, depending on the type of water. These anodes corrode in place of the metal parts they protect and must be replaced regularly before they are completely consumed. A quarterly inspection makes it possible to measure the wear of anodes and to plan their replacement when they have lost about half of their initial mass. It is also important to check that the anodes are in electrical contact with the parts they protect, because a faulty connection cancels their protective effect. The metal parts themselves must be examined for possible signs of localized corrosion that would indicate either a cathodic protection problem or the presence of stray currents coming from the dock or from neighboring boats. Particular attention must be paid to the interfaces between different materials, areas that are particularly sensitive to galvanic corrosion.
Signs of osmosis to look out for
Osmosis is one of the most feared pathologies for polyester shells. This phenomenon occurs when water enters the structure of the laminate through microcracks in the gelcoat. Once inside, water reacts with some components of the polyester resin, creating an acidic solution that gradually deteriorates the laminate from the inside. The first signs of osmosis are the appearance of small blisters under the gelcoat, often the size of a pinhead at first, which can then progress to larger blisters. These blisters are usually filled with a brownish liquid with a characteristic vinegar odor. A boat that stays afloat all year has an increased risk of developing osmosis, as permanent immersion favors the gradual penetration of water into the laminate. A careful inspection of the carina can detect the first signs of this problem, and the sooner the diagnosis is made, the simpler and more economical the treatment will be to implement.
Inspecting the propeller, rudder and appendages
The propeller is an essential element in propulsion and deserves regular attention. The blades should be checked for deformation or cracks, as even a small damage can create significant vibrations that will gradually damage the propeller shaft and its bearings. The blades must be free of significant dirt that degrades propulsion efficiency. The rudder, which steers the boat, must be inspected to ensure the absence of play in its fittings and the integrity of its structure. The hulls, these openings through the shell for the propeller shaft and the rudder wick, also require control because they represent potential entry points for water. Appendages such as the keel, stabilizers or fins must be examined for possible impacts that could have created cracks or detachments. All these elements play a crucial role in the performance and safety of the boat and therefore justify careful monitoring.
Embedded systems maintenance
The electrical, electronic and mechanical systems of a boat that stays afloat are subject to particularly challenging conditions that require rigorous monitoring to maintain their reliability.
Electrical circuit: prevention against humidity
Humidity is the main enemy of electrical installations on board. In a boat that stays afloat all times, the atmosphere saturated with humidity favors the oxidation of the connections, the corrosion of the terminals and the gradual degradation of the insulators. A regular inspection of the electrical panel can detect the first signs of deterioration such as greenish marks on the connection terminals or circuit breakers that show signs of heating up. It is recommended to check the cleanliness and tension of all connections, especially those located in the most humid areas such as the engine compartment or poorly ventilated storage boxes. Applying dielectric grease to important connections can provide additional protection against moisture. The cables themselves must be inspected for any signs of stiffness or cracking in their insulating sheath, symptoms of degradation that could lead to a short circuit. The use of dehumidifiers in confined spaces where sensitive electrical equipment is located is an effective preventive measure.
Batteries: charge monitoring and sulphation prevention
Batteries represent the heart of a boat's electrical system and require special attention when the boat stays afloat without regular use. A battery that is completely discharged or that remains under charge for a long time develops a sulphation phenomenon that gradually reduces its capacity and can make it unusable. For a boat that does not sail regularly, it is essential to keep the batteries charged either through an intelligent dock charger or by solar panels that compensate for natural self-discharge. The electrolyte level of open lead batteries should be checked monthly and supplemented with distilled water if necessary, taking care to never leave the plates uncovered. The terminals must be kept clean and tight to avoid contact resistances that create overheating. A voltage test checks the state of charge, as a lead acid battery must show at least twelve point six volts at rest to be considered fully charged. For older batteries, a capacity test may reveal gradual degradation that will justify replacing them before they leave you down at the least convenient time.
Maintenance of the engine left afloat (cooling, lubrication, regular starts)
An engine that does not run regularly undergoes gradual degradation that can compromise its reliability. Immobilization promotes the formation of condensation in the cylinders, the aging of the seals and the degradation of certain lubricants. To preserve your engine, it is recommended that you run it at least once every two weeks, allowing it to reach its normal operating temperature for at least 20 minutes. This operation makes it possible to evacuate accumulated humidity, maintain the lubrication of all moving parts and recharge the service batteries. The cooling circuit deserves particular attention because stagnant seawater in the exchanger can create calcareous deposits and promote corrosion. For a closed-circuit cooled engine, the coolant level and appearance should be checked regularly. The engine oil should be changed according to the manufacturer's recommendations, even if the number of hours of operation is low, because the oil is loaded with acids and loses its properties over time. Fuel, oil, and air filters should also be replaced according to the recommended schedule to avoid fouling that could damage the engine.
Onboard water network: risks of leaks and stagnation
The embedded freshwater circuit presents two main types of risks for a boat that stays afloat. On the one hand, leaks that may occur on fittings, hoses or pumps and that, if not detected quickly, can cause water to accumulate in the bottom and potentially endanger the buoyancy of the boat. Regular inspection of the visible parts of the circuit and monitoring of the water level in the tanks makes it possible to quickly detect abnormal consumption. On the other hand, water that stagnates in tanks and pipes gradually develops bacteria and algae that give the water a bad taste and can create health problems. To avoid this problem, it is recommended to completely drain the circuit if the boat is not used for several weeks, or to add a bactericidal product suitable for drinking water. Hull valves that allow seawater to be drawn for the toilet or engine cooling system must be operated regularly to prevent them from seizing up, and their pass-shells inspected to ensure they are airtight.
Prevention of fouling and marine fauna
Colonization of the hull by marine organisms is a permanent challenge for a boat that remains submerged all year round and requires regular preventive and corrective measures.
Regular cleaning of the hull in place
Even with quality antifouling, the hull of a boat that stays afloat gradually accumulates dirt that degrades performance and accelerates the wear and tear of the protection. Regular cleaning of the submerged part makes it possible to delay this colonization and to prolong the effectiveness of antifouling. This operation can be carried out by a professional diver equipped with suitable brushes that do not damage the protective coating. The frequency of cleaning depends on local conditions, but quarterly cleaning is generally a good compromise. For owners who want to do this cleaning themselves, there are specific tools such as brushes with telescopic handles that allow you to reach the hull without having to dive. The operation must be carried out carefully so as not to damage the antifouling, using soft brushes and avoiding excessive friction. Regular cleaning has the added advantage of allowing a visual inspection of the shell and detecting possible problems such as shocks, antifouling detachments or the first signs of osmosis.
Anti-fouling solutions for a boat parked all year
For a boat that never or very rarely sails, conventional anti-fouling solutions can be supplemented by specific devices. Ultrasonic systems, for example, emit vibrations that interfere with the attachment of marine organisms to the hull without using chemicals. These devices consume little energy and can be powered by solar panels. However, their effectiveness depends on the configuration of the shell and the local conditions. Hull covers represent another solution which consists in wrapping the submerged part in a membrane that prevents direct contact with water. This approach has the advantage of also protecting the antifouling itself from wear and tear, but it requires professional installation and a significant initial investment. For boats that can move occasionally, even over short distances, this regular navigation is in itself an excellent protection against fouling because the speed and turbulence it generates prevent organisms from fixing. Finally, choosing a well-oxygenated location, with a regular current, naturally limits the development of dirt compared to stagnant water.
Management of seaweed, shellfish and bernies
The different organisms that colonize the shell have varying characteristics and impacts. Algae mainly grow in the first few meters below the surface where light still penetrates and forms a viscous biofilm that increases resistance to advancement. Shells such as mussels or oysters can settle on all submerged surfaces and create significant masses that considerably degrade hydrodynamic performance. Bernies, these small conical shells, adhere very strongly to the shell and are particularly difficult to dislodge. Once installed, these organisms can damage the antifouling by piercing it to fix their support, creating areas where protection is no longer provided. The most effective strategy is to intervene early, as soon as the first colonies appear, because cleaning becomes exponentially more difficult once the organisms are well established. Certain areas such as corners, gaps around anodes or chain passages are particularly conducive to colonization and deserve specific attention during cleaning.
Safety of the boat left at anchor or in port
The safety of a boat that stays afloat all times depends on multiple factors, all of which must be monitored regularly to prevent incidents.
Checking moorings and fenders
Moorings represent the vital link that keeps your boat secure in its location. Constantly subject to the mechanical stresses of boat movements and to degradation due to UV and friction, they require careful inspection. Periodically check for fraying, worn areas, or abnormal hardening that would indicate a loss of strength. Modern synthetic moorings are certainly tough, but they don't last forever and should be replaced as soon as they show significant signs of weakness. Particular attention should be paid to the friction points on cleats, bittes or rings, as this is where the wear is concentrated. The fenders, which protect the hull from impacts against the dock or neighboring boats, must be properly positioned and in good condition. It is recommended to check their inflation and fixation, because a fender that deflates or slips no longer performs its protective function. For a boat that stays afloat all year round, it is a good idea to use moorings that are oversized compared to the minimum recommendations and to install anti-scratch systems at friction points to extend their lifespan.
Protection against seasonal weather (wind, swell, frost)
Each season brings its own set of specific challenges for a boat that stays afloat. In winter, frost is a threat to all circuits containing water, whether it is the engine cooling system, the fresh water network or even marine toilets. In regions where temperatures drop below zero, it is imperative to drain all these circuits or to use suitable antifreezes to avoid breaks in pipes or equipment. Winter storms bring violent winds and heavy seas that place intense stress on moorings and can cause the boat to chase. The number of moorings and their diameter should be increased during this critical period. In spring and summer, thunderstorms can be violent and sudden, justifying the disconnection of sensitive electronic devices and the implementation of lightning protection. Fall often brings heavy rains that can saturate the bridge's drainage systems and create water accumulations. Increased monitoring of weather forecasts and preventive visits before the announced events make it possible to adapt the preparation of the boat to the expected conditions.
Remote monitoring system (cameras, sensors, alerts)
Modern technologies now offer affordable solutions to monitor your boat remotely and be alerted immediately in the event of a problem. Systems such as the Oria Marine IoT box allow you to receive alerts in real time on your smartphone in the event of detection of water in the background, abnormal boat movement, power outage or significant variation in inclination. These devices can also transmit data on the interior temperature, the humidity level or the state of charge of the batteries. The installation of connected cameras offers the possibility of viewing your boat remotely and checking its condition without having to travel. These surveillance systems have a double advantage in terms of safety and peace of mind, especially valuable for owners who cannot visit their boat regularly. In the event of an alert, rapid intervention can make the difference between a minor incident that is easily resolved and a major disaster. Moreover, insurance companies increasingly recognize the value of this equipment and sometimes offer premium discounts for boats equipped with it.
Theft and intrusion prevention
Unfortunately, a boat that stays in the same location for long periods of time can attract the attention of malicious people. Prevention starts with simple measures such as the systematic locking of all openings and the storage of all equipment and valuables out of sight. Specific alarm systems for boats detect movement or panel openings and emit a deterrent siren while sending an alert to the owner. Mechanical locks for outboard motors or tenders are also effective deterrents. It is recommended to create an appearance of regular presence by varying the layout visible from the outside and possibly installing programmers that turn on lights at varying times. Engraving valuable equipment with an identification number and registering it as a photo facilitate their recovery in the event of theft and their identification by law enforcement agencies. Finally, a good relationship with neighbouring boat owners and marina staff creates informal mutual surveillance that is often very effective in discouraging malicious intent.
Indoor maintenance to avoid humidity and mold
The interior of a boat that stays afloat presents specific challenges related to pervasive humidity that can quickly create problems of discomfort and degradation.
Permanent or assisted ventilation
The air confined inside a closed boat is quickly loaded with moisture, creating ideal conditions for the development of mould and the formation of condensation. Effective ventilation is the best defense against these problems. The passive aerators installed on the deck or the descent panels allow permanent air circulation that renews the interior atmosphere without consuming energy. These devices must be positioned in such a way as to create a flow of air through, with air intakes in the lower parts and outlets in height to promote natural convection. For boats equipped with a permanent power supply, automatic fans controlled by hygrostats can ensure forced ventilation that is activated when the humidity level exceeds a preset threshold. This solution is particularly effective but requires a reliable electrical installation and a sufficient source of energy. In all cases, cabin doors, wardrobes and trunks should be left open to allow air to circulate freely in every corner of the boat.
Fight against condensation
Condensation occurs when hot, humid air comes into contact with cold surfaces, causing water vapor to transform into liquid droplets. On board a boat, this phenomenon is particularly evident on hulls, decks and metal walls, which remain colder than the ambient air. Condensation creates runoff that can damage woodwork, fabrics and promote the appearance of mold. To limit this problem, it is essential to reduce sources of humidity on board by avoiding leaving wet clothing or damp equipment inside. The installation of insulating panels on the inside of the shell reduces temperature differences and thus limits the formation of condensation. Chemical moisture absorbers can be placed in the most sensitive areas such as cabins or trunks to capture excess atmospheric humidity. Finally, maintaining an indoor temperature as stable as possible, even if it is cool, produces better results than alternating between heating and cooling that favors condensation cycles.
Cabin maintenance, textiles and interior woods
Fabrics, cushions and upholstery are prime targets for humidity and mold. In a boat that stays afloat all year round, it is recommended to periodically remove these elements to ventilate them outside in dry and sunny weather. Mattresses and cushions should be turned over regularly to allow all sides to breathe. The application of specific anti-mold products for marine textiles can offer additional protection. Interior woodwork, whether teak, mahogany, or marine plywood, also requires regular maintenance to withstand ambient humidity. Periodic cleaning with a suitable product followed by an application of protective oil or varnish keeps the wood in good condition and protects it against moisture infiltration that could cause swelling or deformation. The joints around portholes, deck panels, and cable transits should be inspected regularly as they are all potential entry points for water that could seep in and create invisible damage to insulation or structures.
Dehumidification: electric or passive options
Dehumidifiers are an effective weapon against excessive humidity on board. Electric models with a compressor or Peltier effect actively extract moisture from the air and collect it in a tank that must be emptied regularly. These devices are very efficient but consume electricity continuously, which requires either a connection to the dock or a sufficiently sized solar installation. For boats without a permanent power supply, passive chemical dehumidifiers offer an attractive alternative. These devices contain calcium chloride crystals or silica gels that absorb atmospheric moisture. Their absorption capacity is limited and they need to be regenerated or replaced periodically, but they do not consume any energy and function all the time. Reusable desiccant bags can be regenerated by heating them in the oven or in the sun to evaporate absorbed water. A combination of effective ventilation and targeted dehumidification in the most sensitive areas generally provides the best results in maintaining a healthy indoor environment.
Recommended annual maintenance plan for a boat that stays afloat
Setting up a structured maintenance schedule makes it possible not to forget anything and to ensure optimal maintenance of your boat throughout the year.
Monthly tasks
Each month, pay a visit to your boat to carry out essential checks. Visually check the general condition of the boat, the absence of water in the bottom and the operation of the bilge pump. Inspect moorings and fenders, readjusting their position if necessary. Check the state of charge of the batteries and top up the electrolyte level if using open batteries. Run the engine for twenty to thirty minutes to maintain lubrication and recharge the batteries. Activate all shell valves to prevent them from seizing up. Check for leaks in the water and fuel systems. Inspect the seals on deck panels and portholes. Check that the navigation lights are working properly. Ventilate the interior by opening all openings widely while on board. Drain and clean chemical dehumidifiers if necessary. This monthly routine generally does not take more than one to two hours but allows any emerging problems to be detected early.
Quarterly tasks
Every three months, complement the monthly maintenance with more in-depth operations. Inspect the condition of the sacrificial anodes and plan to replace them if they are more than fifty percent worn out. Clean the hull by a professional diver or with suitable tools to remove accumulated dirt. Check the condition of the antifouling and identify areas that would show signs of significant colonization. Check the tension and condition of the motor belts. Check the coolant level and appearance. Visually inspect engine hoses for signs of aging. Test all electronic equipment to ensure that it is working properly. Check the condition and the inflation of the life raft if it is on board. Check the expiration dates on flares and other safety equipment. Clean and lubricate winches and fittings. These quarterly operations generally require half a day and keep the boat in excellent working condition.
Seasonal tasks
As each season approaches, adapt your preparation to the specific challenges ahead. Before winter, reinforce moorings, check the condition of railings and lines, install additional protection for frost-sensitive equipment, and drain all water circuits if sub-zero temperatures are expected. Check the watertightness of the condom or protective tarpaulin if you use one. Before spring, do a thorough cleaning of the hull and deck, check the condition of all sails and rigging if you own a sailboat, check the condition of the joints and the overall tightness after the rigors of winter. Before summer, check the proper functioning of all air conditioning or ventilation systems, check the condition of sun protection, and ensure that all the safety equipment required for navigation is on board and in good condition. Before fall, prepare for the rainy season by checking all drainage systems and cleaning the culverts that drain water from the bridge.
Essential annual checks
Once a year, carry out major maintenance operations or have them carried out by professionals. Drain the engine completely and replace all filters. Check the condition of the water pump impeller and replace it preventively. Have the cooling system checked. Check the condition and tightness of all electrical connections on the boat. Test the insulation resistance of the electrical circuit. Have fire extinguishers checked and recharged if necessary. Check the condition of life jackets and all safety equipment. Carefully inspect the condition of the rigging on a sailboat. Check the condition of the frames and the structure in accessible areas. Have the residual thickness of the antifouling tested and plan for its complete renovation if necessary. Organize a complete inspection of the hull by a diver or during a water trip. This annual revision represents an investment in time and budget, but it guarantees the longevity of your boat and your safety.
When do you take the boat out of the water despite parking all year round?
Even for a boat intended to remain afloat all times, certain situations justify an exit from the water which will allow interventions that are impossible to carry out while submerged.
Warning signs justifying an exit from the fairing
Several symptoms should prompt the rapid organization of a water outlet for inspection and repair. An abnormal accumulation of water in the seabed despite the operation of the bilge pump indicates a waterway that must be located and plugged urgently. Unusual vibrations during engine operation may signal a propeller or propeller shaft problem requiring intervention in a dry dock. The appearance of osmosis blisters on the submerged shell justifies an outing to assess the extent of the problem and implement appropriate treatment. A significant degradation of antifouling with areas where the gelcoat is exposed requires a complete restoration that can only be carried out on land. Fully consumed sacrificial anodes must be replaced quickly to prevent corrosion from attacking precious metal parts. An abnormal play in the rudder or in the shaft bearings can indicate significant wear and tear that may lead to serious damage. Any visible deformation or damage to the propeller also requires intervention on land. It is always better to organize a preventive trip than to suffer a damage at sea which could have much more serious consequences.
Advantages of periodic fairing even for a boat parked continuously
Even in the absence of an identified problem, a periodic water outlet has numerous advantages for a boat that normally stays afloat. It allows a complete and detailed inspection of all living works, impossible to carry out so meticulously while diving. Hidden areas like the underside of the keel or hard-to-reach gaps can be examined for emerging problems. The fairing offers the opportunity to carry out a thorough cleaning of the hull with more effective means than in immersion. It is also the ideal time to completely renew the antifouling, which allows you to leave with optimal protection for one to two years depending on the product used. Anodes can be replaced easily, thru-hulls inspected and repaired as needed, and all hull equipment can get the maintenance it deserves. This output also makes it possible to check the alignment of the propeller shaft and to preventively replace seals that would show signs of aging. For a boat that stays afloat all times, refitting every two years or at least every two years is an excellent practice that contributes significantly to the preservation of your investment and your safety at sea.
FAQ — Frequently asked questions
What are the main risks for a boat that stays afloat all year round?
Major risks include colonization of the hull by marine organisms that degrades performance and damages antifouling, accelerated corrosion of submerged metal parts, osmosis of the polyester laminate due to permanent immersion, excessive humidity inside which causes mold and equipment degradation, and potential damage to the moorings that could cause the boat to drift during a storm. Regular monitoring and preventive maintenance make it possible to control these risks.
How often do you check a boat that is stuck in port?
A monthly visit is the recommended minimum to carry out basic checks such as inspecting the moorings, checking for the absence of water in the bottoms and starting the engine. For valuable boats or in particularly exposed environments, bi-weekly visits are preferable. The installation of a connected surveillance system allows you to receive immediate alerts in case of problems between two visits.
How do you avoid indoor humidity on a boat afloat?
Permanent ventilation is the most effective solution, complemented by the use of chemical or electrical dehumidifiers in sensitive areas. Doors and trunks should be kept open to promote air circulation, remove all unnecessary textiles and cushions, and avoid leaving sources of humidity such as wet clothing on board. Inner shell insulation also reduces condensation.
When should antifouling be renewed for a boat that is permanently parked?
The duration of effectiveness of antifouling varies according to the product used and the local conditions, but generally varies between twelve and twenty-four months for a boat that remains permanently submerged. The appearance of significant dirt despite regular cleaning indicates that antifouling is nearing the end of its life. An annual visual inspection makes it possible to assess its condition and to plan its renovation before the shell is fully colonized.
What are the best solutions to protect moorings all year round?
Use mooring lines that are oversized compared to the minimum recommendations, install anti-scratch devices at friction points, inspect them monthly for early wear, and replace them as soon as signs of weakness appear. Polyester moorings offer a good compromise between strength and elasticity to absorb shocks. Double the main moorings during storm season and position the fenders correctly to avoid direct contact with the dock.
Can an engine not turn when a boat is still afloat?
No, an engine that never runs progressively deteriorates due to the accumulation of moisture, aging of the seals and the seizure of moving parts. It is imperative to run it at least every two weeks for twenty to thirty minutes while allowing it to reach its normal operating temperature. This operation maintains lubrication, removes moisture, and recharges the batteries. Draining must be carried out annually even with a low number of operating hours.
Should connected surveillance be installed for a boat in port?
A connected surveillance system offers considerable peace of mind by immediately alerting the owner in the event of a problem such as a water inlet, an abnormal movement or a power outage. For a valuable boat or for an owner who cannot visit it regularly, this moderate investment is fully justified. Solutions like the Oria Marine IoT box combine several sensors and send notifications in real time, allowing rapid intervention that can avoid major damage.
