We are now (as of last 7 days ago) owners of a Mariner 31. Based on the info I have in hand, she was built in 1968, is hull number 12 (can't confirm that yet), is USCG documented, and is in fantastic shape. Her name is Ke Luina, reportedly "The Mariner" in Hawaiian. For the time being, we are keeping her in Oceanside Harbor, CA. Cheers, Charlie
