part 4 - electrically propelled vessels

The particular risks related to electric boats are mainly due to the presence of large banks of batteries and associated charging equipment. Hydrogen, a highly flammable gas that is lighter than air, is the by-product of battery charging. This part of the Standards focuses mainly on minimising the risk of hydrogen causing a fire or explosion.

This can be achieved by making sure that batteries are stored securely in a ventilated area, that the propulsion motor is securely installed and that controls can be operated from the steering position. It is also important to ensure that your battery charging equipment and controller compartments are adequately ventilated.

This chapter applies to all electrically propelled boats.
