There's a great one on Echo Point in Alton Bay that used to be part of the Fisher Estate. I know someone bought it a while back and then built a house on the lot behind it.
I remember it being yellow (like the house) and looking like it was about to fall into the cove, but the new owners really fixed it up. I have a postcard with the boathouse and the main house depicted in it. McDude posted it in the Photo Gallery:

It's a great boathouse, on the Peggy's Cove side of Echo Point. You can see from pretty far down in Alton Bay.
