On the C&C 30 if the OP is still considering this boat, should check with local insurance co and they may require a recent survey to put a policy on the boat.
So at the club I was at, they had a large steel spreader frame to keep the slings wide when picking up the boats, without that there would be lots of squeezing at the deck, I doubt the crane co would have this, possibly uses really long slings?
If the topside's were painted that alone is close to $8k job.

1973 OIL CRISIS was the first cost/chemistry switch but it took time to happen
as supplys were used up and makers shifted chemistry
before 73 boat pox was very rare
the 1979 next oil crisis made it much worse
and hulls got thinner do to costs and better stress understanding
iso resin is one way to prevent blisters
many like epoxy coatings but some re-blister
fresh water [lake] is worse the salt esp warm fresh water
trailer dry stored is immune to blisters
not air bubbles and not just water in the blisters they are chemical action
and so return even after a gel coat peal and extended drying and the epoxy multi coatings SOMETIMES
there are hydro lift trailers that are far cheaper then a crane to rent
like 150 vs 1500
they use rams to lift the boat on pads
if he has a decent ramp
