hmmm that's interesting, last I heard they sold the 24' molds to Topaz and were no longer making Silverhawk boats. Looks like they have a new website.
http://www.silverhawkboats.com/
The guy that used to build them used to stop by CSC.com. His name is Mike Witte I think, nice guy. He actually sent me the wiring diagrams for the 24 he used to make. I still need to get those up on the site..
