I have the pole; it's a 100% carbon windsurf wave mast @465 cm, official weight is just under 4.7 lbs, and official cost was $95. Base fitting just needs some more grinding for a good interference fit; the tip already has a thick aluminum liner (dead Gary Fisher handlebar section, about 2 1/2" long) Wested in. I have some ideas for the strut(s); one recommendation was to make them 12" long and about 30 degrees apart, but I'm thinking a bit longer. I want the high point of the pole to be as high as possible, while still taking max advantage of the 15' length to lower the hound on the mast and "lay" the chute back for more bow lift a la the skiffs. God knows the P-19 needs it!

As for the "clarification:" I know it has been scored the other way, with the lesser hit for two sails than for one. I also know that I haven't seen Beuerlein carry both headsails in quite some time...it's very possible that they began scoring according to the "clarification" and the 2-headsail rig lost a bit of its "charm", shall we say.
Anyway, if you have facilities for welding/otherwise fabricating aluminum, please email me.
thanks, and
sail fast
