I found a nice ali boat on sunday 59m on a sandy bottom.
Kinda thought it would be fun to raise it .
Its 5.5 long ish by 1.5 beam. its well made and is pretty thick possibly 3mm.
its got speaders and crossmembers every where.
Possibly used by the germans for beach landings.
So how many ltrs of air to raise it ?.. best method
Got a group dead keen on doing a padi search and recovery speciality type course

u will need shit loads of lifting gear for that, might be cost prohibitive to do as 59 mtrs is deep for working.
with regards to the legalities - best to ask are the local marine authorities i guess.
the local coastguard over here once had found a moring anker and a member had asked me to help them lift it for them, my pay would have beenn to be mentioned in the local coastguard news paper.
well i gave them an estimate what i thought was needed ( 2 barges, one with heavy duty crane, several 1/2 ton lift bags, divers to be able to work at 30 mtrs, etc) and that was the last thing I heard about it. To my best knowledge the anker is still there. Agreeable your object is a lly boat whereas teh anker was 12 foot solid brass, so your lift will be lighter but form greater depth.
on another note as I am german, i might want to claim customary rights on the boat as soon as you have got it up :-)
