The tender is not bad - built by a local guy out of Kingston, MA about 10 years ago is all I can gather from the previous owner. Hard to tell what its made of - but is solid hardwood, with the exception of the bottom - which is Marine ply. Seems the hardwood is very hard and has a closer grain then a typical pine/cedar - and is very overbuilt - niot sure what it is. The only soft area's I can find are on the ply in two small spots. I'll probably clean-it up and if I get the gumption replace the bottom over the winter...It was fiberglassed on the bottom - and I've removed all the glass already - giant peel and eat shrimp........
