Roger that, here we go.
I'll try to be brief, but doubt it.
Rig any sail on any mast????. Strewth where to start. OK. IMCS does not equal curve. A mast can have a top half that is flexy in relation to the bottom and still be (for example) a IMCS 21. That's a Fact.
If the sail is designed on a very constant curve mast, it will set crap on the *same stiffness* mast with a flexy top. Downhaul and outhaul fiddling
will not make it set optimum. That is also Fact, sorry skipper. BTW I've got 17 years rigging and sailing many brands.
For a real insight (you may have to suck it up and just deal with the fact that it is real scientific measurements) try:
www.peterman.dk/windsurf-mast-article-gb01.htm Cut open *A* board??? No, many.
Nothing to back up my claims? Have a look at the pics from last time we all debated this crap. Two boards, both from cobra factory, both are "carbon sandwich". One has only one x 4mm divinycell with a strip of 4" wide carbon up the middle, the other has a double sandwich with half the deck covered in carbon. The latter is obviously much stronger, neither brand lied in their advertising as all they said was "carbon sandwich". The proof is in the pics.
You say they are "the same technology" mate you must work in marketing. By your logic, the space shuttle and sailboards are the same technology. Check out the mistral on boardlady.com which claims to be carbon yet has none.
Now how pissed off would you be, if you and a mate bought boards that claimed to be same technology, but yours busted 2 years before his and turns out it has less 'good stuff' in it???? And then you start hearing "yeah they are apparently a bit fragile" from a few sources. Too bad if you bought that one huh. No I didn't but one, it didn't happen to me so I'm not being a sore loser I just feel sorry for the poor buggers who have bought boards that are marketed as same construction but are waaaayy weaker. I'll give you a tip, that is the experience of a few ppl with JP, F2, Mistral and Tiga in particular. . Give me RRD, Starboard, Quatro any day.
