2012 Glacier Bay 2740 Owners Manual
The electrical system on your catamaran consists of three major components: the battery system, wiring and circuit
protection, and accessories. It is important that you understand the principles of the electrical system, so that you can
protect the components and troubleshoot any problems you experience.

Your Glacier Bay is equipped with three batteries. Two of the batteries are dedicated as “cranking batteries” the third
bank controls the DC accessories and is commonly referred to as the “house” bank. To help maintain your batteries, a
management system is installed on your boat. Chapter 6 of this manual will provide details regarding the location and
wiring of your batteries and management panel.
6.5.1 Emergency Parallel
In the event of a battery failure, the battery management panel allows you to mechanically link the port “cranking”
battery to the starboard engine or vice versa. Please refer to the model specific section for more details.
The push-in or toggle style breakers located across the top of the management panel protect the 24 hour essential
circuit wiring. Per NMMA and USCG guidelines, these breakers are constantly energized to provide power for bilge
pumps and memory functions. This helps to protect your vessel even when you are not available. The “HOUSE”
switch does not need to be “ON” for these breakers to have power. Inspect the breakers regularly, and push-in or flip
the toggle to reset. If a breaker trips constantly, have your dealer investigate the problem as soon as possible to
prevent damage to your boat.
6.5.2 Anchor Windlass
A 50 Amp breaker is installed at the factory for owners who request the anchor windlass option, otherwise a blank is
installed to permit aftermarket additions. If you choose to add a windlass to your boat, contact your dealer for
information on selecting a breaker to fit the panel.
