I'm looking for an used F18 but unfortunately quite limited in budget. I'm not much familiar with Cirrus B1 model. Can anyone give a short introduction and compare its performance with Hobie-Tiger, Wildcat and Nacra f18 infusion.
Honestly, any of the boats that have the higher aspect ratio wing mast are reasonably competitive. That started in, what?, 2006/7 about the time the Nacra Infusion went into production. The Hobie Tiger and the original Nacra F18 use a tear-drop shaped mast that seems to have been out-developed.
