[PSUBS-MAILIST] Surface Transit and power requirements

[Alan]

Hank,
I have thought about buying a small inflatable that I can flip
upside down on top of my sub for transport.
That way you don't need another car & trailer for a support boat.
It would be good for extending your range a bit & enabling
you to transit to the dive site in a bit more comfort.
Also you could accommodate a support person & mount a 
dive flag on it.
Of course it would have it's limitations.

The idea is it will fit in a 5 gal pail with a sealed lid stowed in the sub.  I will make a mount on the deck of the sub to clamp it in.  I should be able to make 60a at 24v with it.  I am just not jumping into this until I   am sure I need it.   With 8 agm golf cart batteries I think I will have a 14mile range?
