[PSUBS-MAILIST] Sub launch musings

[T Novak via Personal_Submersibles]

The A-frame crane would not likely have sufficient reach.  They usually are used on board ships to lift a sub out over the transom.  The same with knuckle boom cranes, like the ones used to launch the Mir twins.  These are used just to launch over the side of the ship.

 

Hank has it right with a barge mounted crane.  The barge can be launched in much shallower water while holding the sub than the sub launched alone.  With a pontoon or moon pool barge even a gantry crane would work.

Or ... an A frame crane mounted on the back of a flatbed. Can you back down a ramp far enough for sufficient water when swinging it off the back? I like the idea of one vehicle for travel.
