Hi James. I'm using 4
Minnkota saltwater 101's. They will be pressure compensated with air. I'm just
not keen on the oil compensation method. A scuba regulator and small tank
located outside the hull will keep the pressure slightly above ambient. Scuba
tank compressors put very little moisture into the air. I've been diving
for years, and it's always a challenge to keep your body hydrated when doing
multiple dives. This is because each breath removes moisture from your lungs.
Actually, quite a lot of moisture. If you dive 3 or 4 times in one day, you can
get pretty thirsty! Of course, some dive shops have better compressors than
others, but with a little research, you can find a good one for dry tank fills.
Speaking about air, I'm making a change
to the body. I want to add two additional scuba tanks to the outside, and to
keep them covered so there's minimal issues with entanglement. The pictures so
far show the big fin on the back end. I'm adding two rounded tubes to
the lower fin area, so that when the lid is closed there's room underneath for
the two additional tanks. The new shape isn't quite so smooth, but the extra HP
air capacity is required for the increased ballast tank size. I originally had
enough room for the small compensation tank just below the finned cover, so
with a couple of " humps" added, I can fit the two new tanks under
there too. This is in addition to the tanks inside the sub.
Well, better get back up to the
shop. That thing ain't gonna build it self. Frank D.
