For installing the synthetic teak, aligning the wood pattern would be key to a nice looking job. I was thinking about removing each piece separately, then gluing on the synthetic teak, and trimming it with a router. That would give me a nice finished edge. Aligning everything is the hard part. Once you put the stuff back down you don't want to see any crooked lines. That would drive my wife nuts.
Carpet on a boat Yngmar? A couple of throw rugs, sure, but not carpet. A recipe for a nice moldy smelling boat.
