It is very surprising that the F-39 tri was so slow. This should be a fairly fast boat. I have a smaller 31' tri (F-9A) and the fat cats are no competition for it. However, I've never sailed with them over longer than a 2 day race so maybe the F-39 was drastically slowed by excess weight, inexperienced crew, lack of sails, or malfunctions. Even with some extra weight though, I would not have expected the smaller fat cats to pull away like they did. That is a very nice looking F-boat.
