Has anyone heard of a Sea Crown day sailer?, 18.5' Built in 1985 I saw one on E bay, looks cute, missing mast, rigging, tiller, etc. I couldn't find anything on NADA. 1st part of ss# is XMF I really need another boat, and the Admiral will kill me if it turns up at our place. I already have 2, and a motorcycle. Any way I was just curious as to why it isn't listed on NADA
