Hi Brian!
I have seen old pictures of a psub with tracks somewhere before. At
this moment, I can't recall just where, but perhaps others might? If it
comes back to me I will let you know.
Cheers!

Vehicle that I had in mind would not be a part of the submersible, the
sub would rest on top and lift free when the track vehicle got deep
enough. After that it could just stay put on the floor until the sub
returns, sub settles down on track vehicle and then drives out.

Note: Sent this last night but it appears to have not gone through
or was restricted to size. After multiple attempts on Joe?s and my part
to get this loaded, now breaking it into 4 parts.
Part 2 of 4
6. Wheeled submersible
a) Pros:
i) Simple solution
ii) Tires can be filled with water to negate buoyancy issues
iii) Negates ramp issues (except where a whole exists at the end of
a ramp in skinny water)
b) Cons:
i) If directly under the sub, increases draft
ii) In a K-series submersible, if placed on the sides would
significantly increase beam
iii) May get mired in the muck before getting to the channel
iv) If powered
(1) Increase power consumption
(2) Increased complication due to drive train
7. Tracked submersible
a) Pros:
i) Negates ramp issues (especially if powered)
ii) Should not get mired in muck due to increased foot print of
the tracks
b) Cons:
i) Adds extreme complexity to a system
ii) Increases drag
iii) Increases power requirements and transmission if powered
iv) WW II German Seeteufel was not successful
v) All other applications of tracked submersibles have been
powered from shore or the surface
vi) Large increase in cost
vii) Still have to get to the channel and dive site
8. Fork Lift Launch
a) Pros:
i) Simple solution for launch/recovery
b) Cons:
i) Not all marinas/yards have a fork lift
ii) Many Florida yards/marinas will not service you if you are not
a regular customer
iii) Launch/recovery costs quickly add up
iv) Still have to get to the channel and dive site
