I've read about the bow tangs failing on N-20's. You can't furl the jib on these boat to shorten sail if needed.
I've read of exactly one breaking on these forums. Its certainly not a pandemic. N20's are subject to all the regular causes of boat failure. Poor maintenance, reckless abuse, catastrophic accidents do not escape the 20 or the F18s.
What they do give is a balance of performance, seaworthiness, and reliability. The reasons I have for thinking that the TheMightyHobie18 is not well suited to this race has to do with the fact that its simply not up to par in the performance meter with the other competitive boats.
If the event turns into more of a race than a rally, and the organizers get more than a pigboat Hobie 33 as a chase boat, then I'll seriously consider doing this race. (if it even happens, which I put at 50/50)
