Course made good efficiency in a Tandem Island

Yup, definitely confrontational. And you're surprised you didn't get helpful responses?

Being newish here doesn't mean being new. For over 20 years I've sailed and raced many boats from Lasers to H16 to Nacra F18 to Corsair trimarans. But it seems you were so busy preparing your snarky answer that you ignored the part where I (and others) were trying to be helpful. I still have the Corsair and bought the TI for totally different reasons.
I've seen lots of people on lots of forums get helpful answers and others who didn't. Asking a different question to get a different answer and being open to learning something new go a long way towards get helpful responses. But I suspect all of this will be lost on you so I won't attempt to add anything further.
Too bad, you missed an informative discussion.
