First step of repairs
might be to check for distortion in the vessel. After checking all the damaged sections for anything that looks like a possible future failure point, if none, I would fill/fare the the dents under the waterline. The dents on the chine need a more serious approach and replating the sections after repairs
to some of the frames that one would expect some slight damage to. All this is just speculation, I would have to grill
the brother in law on that as he is the Aluminimum welding guru.
A local yachtie bought a boat off an insurance
company for $6K AUD, it is a nice steel ketch
, 44' long with lots of good gear
, it sunk up to the deck
level and sat there for a few days. A big task ahead but the gear
on the vessel is good quality and much of the internals are fine, it is getting a engine overhaul
and the electrics need rewiring.
