When you drop the keel, or raise the boat, you are losing a lot of the weight. If you build a cradle, make it so that you can detach the keel, jack the boat up, fix the hull
, and lower the boat back onto the keel. Frozen dirt oughta hold you just fine.
I thought the work was going to be done at a boat yard (?). Sounds like they are trying to burn someone a new one. Try this: Put boat on travel lift; lower boat to set keel into hole in ground 2/3's of keel depth
; unbolt keel; raise boat; set boat on multiple jack stands or cradle; repair fiberglass
damage, lift boat; position over keel; lower boat onto keel; rebolt; lift and splash. This should not cost more than twice a normal haulout for the 'lift and move' parts
of the process, no where near $36,000.
Bring it here - I'll get ya patched up for half price! ;-/
