David,
You might want to rethink that 50 HP motor. If you have only one prop
with all that power, won't you send your sub rolling through the water in the
opposite rotation of the prop? Two opposite rotating props would fix that,
but still, that's a lot of HP.
With a sub your size, you'd fly thought the water with 15 HP.
Submerged, you have to be in pretty clear water to use 5 HP.
Just a thought, Dan H.

is this e mail going thru?
Hello everyone,
Just wanted to introduce myself, my nave is David and I work as a
Industrial fiberglass technician in Wilmington DE. For years I contemplated
building a small submersible capable of carrying two people to a dept of 130'.
Recently I decide to go ahead and start building my sub. It will be quite a
challenge. The sub (X 303) will be built in 4 module sections 24" in dia and a
total length of 20'. The sections will be fabricated from 3/4" FRP which will
bolt together internally and will displace approx 3,000 pounds. Power will be
derived from a 50 hp 2cyl engine thru a 2:1 gear reduction driving a 14" X 13p
propeller. A marine alternator will be coupled by belt to the engine to
recharge the gel cell batteries. I have begun constructing the bow/
forward ballast compartment and hope to complete this section by months
end.
I have laid up the bow sections and joined them to a 24"l section of
pipe next is to lay up the 1 1/8" internal flange and join it to the bow
section then overwrap the whole bow/ballast section to build up to the 3/4"
thickness I am looking for. more pics to come
