Many larger Grady-Whites including the 290, 300, 305, 330, 336, 360 and 366
have two electrical power systems: Direct current (12V DC battery
power) and alternating current (120V AC shore power or generator
systems). Safely and efficiently using these systems is simple, yet
requires some basic understanding of how they work and how to use them
properly. This Docklines covers simple basics of the electrical
systems panel box and electrical loads. Later issues will cover the DC
(direct current) and other systems in more detail. Take a look at Eric Sorenson as he shows how to use the panel box aboard the Express 330;
other boat models with like systems operate similarly. Also note that
while this video communicates the basics, there's no substitute for
reading and understanding the details in your Owner’s Manual.
In this video, Eric Sorensen gives a brief overview
of the Express 330 electrical systems.
AC (alternating current system)
- The boat’s electrical system is divided into two sides on the main
electrical panel in the cabin: on the left are controls for the 120 volt
AC systems (just like systems in your home), and on the right are the
12 volt DC controls. A voltage and amp meter is clearly visible on the
panel so you can monitor loads.
- AC power comes from shorepower when the cable is plugged in at the
dock, and from the generator when out on the water. Make sure you don’t
try to start up too many loads at once as both generator and shorepower
capacity is limited to the noted amp loads. (See your Owner’s Manual for amp information on various electrical devices.)
- The 4kW generator that Grady-White currently installs is rated for
31.6 amps continuous and 35 amps peak (up to two hours). Shorepower
capacity is 30 amps. (The 8kW generator and two shorepower systems on
the Express 360 roughly doubles the load capacity; check your Owner’s Manual.)
- When shifting between shore and generator power, make sure to shut off the systems first.
Ladies on Gradys....
Think a boat is difficult to run, ladies? Not so! Just ask Captain Gail Christensen, owner of a Grady-White Express 360 AND a Canyon 283. Surprisingly to some, bigger boats are often easier to operate than smaller ones!

Take a video walkthrough with Grady engineer David Neese aboard the newest Grady-White model, the Canyon 271. What a great family-and-fishing boat!
