What you need is a casement for a tidal driven dry-dock. Float in, let

Something like that?


Why make it so complicated and expensive?

Just hoist the darned thing, fix the problem, then splash.

Sheesh! Sounds like a bunch of Mensans around here!



This IS a form of hauling - but could be a whole bunch cheaper
and less prone to hull damage.

Float in, settle into the slings as the water goes out.
Then close the doors for a dry place to work - until you are done.

Come to think of it, wasn't this technique used in the South Pacific
during WW-II?
