When I bought my Spitfire, it was grandfathered in to the F16 class. I gather this is no longer the case, which is a pity. I'd have been quite happy to race head to head. Meanwhile, I remain interested in F16 as a concept, and take part in this forum because of the relative similarity of these boats (and the Shadow).
On average my boats meet the weight limit (Spitfire @ 135kg and Shadow @ 99kg), and I can sail one-up or two up. Or did I miss the point? <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
