I recently acquired a vintage wood rowboat, and was wondering if anyone could help identify the maker. It looks similar to some of the old "Rhinelander Guide Boats" I have seen photos of. It measures about 48" wide at the beam, and about 15' OAL. The boat basically needs about all of the ribs replaced, and much of the bottom planking. It was planked with 1" wide cedar, and covered with fiberglass. Not sure if the fiberglass was original, or if this was done at a later date. The upper planking and gunwales are not in too bad of shape. The keel has a 1 1/2" wide strip of brass running the full length of the keel. (The fixture on the front seat is a later, more modern addition - possibly for a depth finder or something.) Can anyone help? Thanks.
