Jim,
More important then the percentage of your total
subs weight is the weight they will allow to be pushed out of the water.
Take the weight of the water your tanks will hold and figure how much of the
sub will be lifted out to see how much free board you'll have.

Subject: [PSUBS-MAILIST] Soft
Tanks
Hi All Psubbers,
I have completed preliminary design of my soft
tanks and am looking for input. They will be shoulder tanks tapered from the
sides and ends at 2-3 degrees to minimize the chance of bubble entrapment.
As they are now the will support about 12 % of my subs total
weight.
The bottoms will be mostly closed with rows of
4 inch diameter holes to minimize burping in rough water.
Does anyone have a guideline on this area as to
what percentage is good etc.
Best Regards,
Jim
