There is a difference between boating in salt water and boating in fresh water, and that is that boating in salt water requires a number of special considerations. Electric motors for boats in salt water have to withstand the corrosive nature of salt, among other things.
Types of electric boat motors
- Outboard engines: These engines are primarily intended for small boats and are mounted on the outside.
- Inboard engines: These are more commonly used for larger boats and are installed inside the hull, connected to the propulsion system via a shaft.
- Bow thrusters: These are basically used for precise manoeuvring and fishing. They are designed to have a low speed, and to have the precision we have mentioned.
Characteristics of electric motors for saltwater boats
- Corrosion Resistance: Motors should be constructed of corrosion-resistant materials, such as stainless steel, anodised aluminium, and other corrosion-resistant materials. In addition, it is common for electrical parts to be hermetically sealed.
- Protective Coatings: It is common for engines to have additional coatings to protect against salt water, such as special paints or anodisation.
- Cooling System: Some engines may have special cooling systems to handle the heat generated by prolonged use.
- Regular Maintenance: Despite the protections, it is crucial to perform regular maintenance, such as flushing the engine with fresh water after each use and checking parts that may be exposed to salt water.
- Power and range: The choice of motor will depend on the size of the boat and the distance you expect to travel. Electric motors can be powered by lithium-ion or AGM batteries, which vary in capacity and recharge time.
Respect for the environment
At Sondevela we are aware that it is important to leave the minimum impact and minimise our footprint on nature and the sea. Not only does our catamaran, as the name suggests, use sail, but we also take into account everything from the speed of navigation to minimise emissions, to the exhaustive control of solid waste, ensuring its correct disposal in the ports. Gestures that, between all of us, help to keep our oceans cleaner.
