Electric engines are becoming an increasingly popular choice for large powerboats as technology advances and the boating community becomes more environmentally conscious.

Perhaps the most important use of DC power on a vessel is for starting the engine. Thus, it is prudent to always assign one “isolated” battery or bank of batteries for the sole purpose of starting the engine and assign another battery or bank of batteries to “the house”.

Finally, there is something called a “sea anchor.” These can be a variety of devices used to slow down a vessel caught in high winds and turbulent seas.

While water can be dangerous, so can the stuff that lies below it. Thus it is important to know, for sure, how close it is to fragile stuff on the bottoms of out boat such as the propeller and rudder if fitted.
