    If I recall the Express 37 and 34 have all the heavy stuff on starboard. Even the anchor locker is on that side. The theory was it's better for going to Hawaii...

    Bob,
    I highly recommend Nigel Calder’s book BOATOWNER’S MECHANICAL AND ELECTRICAL MANUAL to help guide you through making any electrical changes, modifications and/or upgrades. All the tables and data you need are in that book.

    Keep in mind that the battery cables need to be sized to minimize the voltage drop in the run, preferably no more than 3% loss. The length of run is the total ROUND TRIP. Over current protection (fuses, circuit breakers, etc.) are there to protect the wires not the devices, so if your electric winch is tripping the 50A breaker, make sure the wire is large enough for the load before going to a bigger breaker.

    I also moved the batteries forward in my previous WC30. My new boat has a very minimal electrical system, but Im already making big changes.

    Fun, in'it?

    Roger (and thanks) on the battery cables, breaker, etc. Scott's been doing some more work on the rig and has tripped it a couple times, but it beats burning the boat up. I'm trying to get to it. Time vs. money...
