Shipmate has been resurrected by a dedicated stove fan right there in PA close to the original shop. ShipMate Stove Company Inc. - your source for classic solid fuel boat stoves, heaters and sinks.
While I understand he has some access to parts for the old shipmate lpg stoves the new owner's focus is currently on cast iron wood burners. He is using original casting molds though the feet have been beefed up a bit and draws help from a few of the old Shipmate hands in the production of the stoves.
His most interesting stove r&d has to do with an all stainless, deco looking wall mounted pellet stove for more contemporary boats and he his working on bringing out a folding sink. Prices are very
competetive and the stoves are all U.S. made in PA. Good guy and as an owner of one of his stoves can vouch for their quality.
