I'm pulling from the back of my mind some rule that steel should to be 3 to
5
times thicker than the minimum needed for strength to compensate for
corrosion. This is not what you find in the average 30 year old Taiwanese
trawler engine room.
(endsnip)
Ah! The light begins to dawn . . . these are relatively thin wall tanks
then? Mine are 1/4" steel plate. Unconsciously I guess I had just assumed
everybody's would be . . . steel plate is cheap, much easier to
weld/fabricate over 1/8" thick, and the weight is pretty much irrelevant
considering the weight of their cargo. If I were going to make a
(smaller)steel tank the minumum I would use would be 1/8" plate.
I intend to keep the integral tanks and was beginning to wonder what I had
missed . . . modular tanks instead of integral tanks would just make areas
of the hull hard to reach for future maintenance (under tanks) and reduce my
capacity. She currently holds over 700 gallons, and day-tankage will add
over 300 more.
