Hi

It is possible to build a cradle around the hull to turn it if it is
only that weight, but you better stay clear if you don't design the
cradle perfectly safe. anyway if your boat are fiber glass, I suggest,
you look into how to make a sheet to fit exact and around the edge of
where the dameage are, if you before this angled the remaining edges in
the hole the right amount, you can from inside use that patch to mold a
new surface that in glasfiber or Epoxy and glasfiber then patch the
hole from inside.
So maby your repair don't ask you to roll the boat.
