I've been googling like crasy, and searching here and all I can come up with is old references, dead links but no plans out there for a beach landing craft. There's lots out there for aluminum construction like this guy:
This is pretty much what I'm interested in, but slightly bigger and for plywood construction. I'd want a payload to be able to haul a full sized vehicle plus. Say 10,000 lbs. I know its about as simple a design as can be but I'd prefer to find some plans for wood construction with an acredited designer's name to it. Any ideas???
