I have taken a different approach to the surface propulsion problem with my
little sub project.
My initial design was to couple the sub with a surface craft like a small
pontoon section which would carry a compressor, generator, and outboard motor to
power the sub. Now I am adding a motor mount on the back of the sub that can
accept a small outboard like maybe 20 horsepower for surface travel. When I get
to the dive site, the small outboard will be removed and stored on
an accompanying motor boat while the sub goes down, or possibly inside the
sub. I have a sketch of the structure for the rear ballast tank and motor mount
on frappr. Here's the link to see what it looks like.
I've got the parts for this in the shop and will start fabrication as
soon as I finish the hatch hinges and lock-down dogs. Hope to get some pictures
of that part up soon. ( Man!!! it takes a lot of grinding to fab these parts.)
