I am a member at Gulfport Yacht Club (just south of St. Petersburg,
http://www.gulfportyachtclub.com). This is a dedicated cat club with club races twice a month, with usually 10-20 cats racing on Portsmouth (Acats, F16-18s, h16-14 etc). Unfortunately the central/west Florida Hobie racing scene is not very active, we might have a H16 fleet at some of the Harken series events, but that is about it at the moment. Our club is actively trying to increase Hobie participation (at the moment we only have two H16s that actively race), and there is interest by the club officers to resurrect the hobie fleet if we can increase our hobie membership.
Non members are welcome to participate in the club races (usually 3-4 races on saturday pm) for $10, which includes dinner at the club afterwards.
This weekend we are having our two-day spring regatta, and it looks like we will have close to 40 boats participating, but only a handful of Hobies have signed up so far. Other fun regattas are the SCCA Kelly Park regatta (first weekend in June, Friday-Sunday), the Daytona Summer Sizzler (don't know the date yet, usually towards the end of June), and the St. Eustis regatta (usually held in the middle of October), each of those had a H16 fleet last year.
Anyways, feel free to drop by anytime!
