Re: How important is fuel capacity?

Answer kind of depends. Based on your plans to run a generator and possibly air conditioning then definitely more is better but...

Will you be cruising remote areas with limited access to refuel?

How long would you expect to spend off the grid away from fuel supplies?

What other sources will you have to charge the house batteries?

Depending on the answers to all the above 150 gallons might be significant overkill or might be sufficient. Unless you plan on spending months in the middle of nowhere don't thing you would need more than 150 gallons.

One thing to consider, on a cat additional weight is a real performance killer. That much fuel will add over 1000 lbs to the boat. If I felt the need to carry that much fuel I would certainly split it between at least two tanks and only fill all when necessary.
