I bought a new Stiletto 23 from Force Engineering located in Sarasota, FL back in 1984. This was a great boat and I had a lot of fun sailing it. Too bad they didn't continue making them. The people that owned Force Engineering had the last name Nichols, and as far as I know still sell reconditioned boats around the same location. I have seen their advertisement regularly in the classified section of Multihulls Magazine.
Stiletto 23', 27', 27'GT, 30'. Fast and Fun! All models available, many to choose from. Factory refurbishing, modifications, and parts available.
