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
