Dave,

Marstrøm used to build a boat he called the M-18. The M-18 was based on his A-cat, but was wider and had a spi. I dont remember what else was different from the A. I think the boat Mitch and Herbert used in the ICCT was an M-18 de-tuned and rigged to F18HT specs. It was not very succesful as I remember, so I guess the boat was either sold or are in storage somewhere. The extra lead in the mainbeam is probably worth some money. Perhaps it is in the same storage as the 20 foot carbon Fox he has sailed in Rounde Texel <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
