Yeah, interesting.I think so too, someone asked me for more info and I contacted the seller with no reply.
The only thing that made me skittish about it is that according to the current owners is that it was sheathed with Dynel/epoxy in the early 90s. When asked for details the seller said the bilge was still bare wood, and that they always kept it wet, then went on to note that it naturally stayed wet anyways, but no inspection had been done since then other than some small repairs. They also said they had a big roll of the Dynel on board for repairs. When I asked if they would be comfortable with a potential buyer having a couple fasteners pulled to check(and the grind off/re glassing and filling/fairing/paint at buyers expense (really not hard on a 4" patch max) they said there was no way they would consider any sampling of the hull/fasteners. 37 year after sheathing, I would like to see what condition the underlying wood/fasteners were in before buying. Then I found out the boat was in Mexico, not Canada where it was posted.
The links you posted note a boat with two cabins, and two heads. The one for sale was a single head where the V-berth would be, one quarter berth, and a convertible dinette. I wonder if it was later converted or if there is more than one out there?
It was modified by the previous owner, he put a workshop in the aft cabin but left the bunks underneath.
