I'm really surprised by the total lack of information about Sundance sailboats and the manufacturer (now defunct El Mar Boat of Roseville) especially since they are local here in Michigan.
Found another Sundance 23 in Michigan through another sailing forum. Guy gave me some specs, has more information, when he gets off the road. Boat's for sale, 1974 model.
Looks like the other 23 owner posted once and disappeared.
Well-built little boats. Yes, and the deck space sucks!!!! Lots of sailboat owner friends comment positively on my boat, which makes me feel pretty good about her.
Wendy0, got any pics?
