Like water pressure in a pipe. This can be a real problem with some types of electronics or with electric motors, which will run more slowly at 11.5 volts. Per ABYC (E-11.16.3.7), “Solder shall not be the sole means of mechanical connection in any circuit”. Typically, the marine-grade wire will be superior than the automotive counterpart in these areas as well. In general, wiring on boats should be of the stranded type, not solid copper wire used in household applications, which does not withstand the vibration found onboard a boat. When you install basic boat wiring the distance from the power supply to the component and back must be. Note the large red and black wires in both pictures.

Boating Magazine's Powerboater's Guide to Electrical Systems by Ed Sherman Sailboat Electrical Systems, Don Casey, 1999 International Marine Boatowner's Illustrated Handbook of Wiring, by Charlie Wing Your Boat's Electrical System, by Conrad Miller and E. S. Maloney Managing 12 Volts, Harold Barre 1997 Summer Breeze Publishing Most importantly, SAE wire is up to 12 percent smaller than American Wire Gauge (AWG) Boat Cable which means that, in many applications, larger gauge wire must be used to stay within the voltage drop limits recommended by experts (see our West Advisor on Marine Wire Size and Ampacity). And if all this info is new to you, you’re probably best hiring a professional marine electrician to do it for you (local install support directory).
