In a sailboat, maximizing tank size is going to result in an irregular shape

Disagree. Tanks that are less than completely full condense water
during thermal cycles, and water being heavier than gas or diesel, it
collects at the low point. This really ought to be a small sump, need
not be more than a tea cup - where it can be checked via a sampler.
Nothing stops an engine better than water in the fuel.

Brian Whatcott Altus OK

Which all the more reason to end the season with full tanks. The only
time I experienced problems was from a load of contaminated fuel in mid
summer. My point is that unless your tank has a large flat bottom you
are in fact adding a sump to a sump.
