Don't forget that Subchapter K (the 46CFR passages) are for vessels
carrying passengers for hire. Their rules are much stricter than
those for rec. vessels, presumably because recreational vessels are
used more "voluntarily." Subchapater K covers vessels up to 100 tons,
so they are not really thinking of 40-gal fuel tanks.

ABYC publishes a book that puts together in one place all the federal
regs for recreational boats -- a good thing to have.

What has me really confused is the relationship between 33 CFR 181 - 183
and 46 CFR. They are not easy to figure out in the first place and the
way they are presented on the web makes it a lot worse.

SAFETY STANDARDS FOR BACKYARD BOAT BUILDERS has nothing in it that
applies to diesel powered vessels over 20'. I guess I will have to
spring for the ABYC guides but from what I have seen so far they don't
track exactly with the CFRs either.
