I have this trailer:

http://igor.chudov.com/projects/12-f...raft-Seafarer/

I would like to know if it is safe, or legal, to convert it for
hauling cargo, AS WELL AS the boat. Like adding plywood and removable
stakes etc.

I don't know about legal (and I'm sure that would depend on the laws of
*your* state). But I see no physical/mechanical reason why it couldn't be
done safely, although you will very likely have to weld on some additional
square tube framing and support members to ensure that it's strong enough.
