[PSUBS-MAILIST] freya/ tank question
Nice pictures from Peter
his craft. I think he has built a very practical sub seen the number of dives
and the possebility to operate autonomus.
I got a few questions about
(ballast) tanks; hope somebody can help me.
-is my tought right that saddle
tanks placed on the waterline (like a Seehund) add surface
stability?
-Is a sub with only 2 hard
ballast tanks more difficult to trim?
-What is better for a psub soft
ballast tank, an open water inlet or with a valve?
thanks in advance and keep up the
good work.
regards,
