The Isotope Catamaran is a registered Formula 16 boat! The hulls meet the 16ft LOA requirements of the Formula 16HP class. The strong points of the Isotope are that its balanced helm allows it to out point any other catamaran to windward. An Isotope meeting the One Design class specifications can be raced as a single handed Formula 16 boat. An Isotope with a spinnaker can be raced with crew in the Formula 16 one up class.
Jalani, thank you for finding that. I had no idea. I don't recall it ever being mentioned on the F16 site. Very interesting -- well, at least to me. I thought maybe they had too much sail area, main and jib, to qualify as F16.
P.S. Maugan, see, now we are sort of back on topic about the Isotope.
