Skippers, I'm in the home stretch of rebuilding my old Dumas, working hard to make the Triangle Cup in Raleigh, and have only, in addition to tank testing and trimming, making up of the rigs left. I've got one new set of John B. "A" sails, and several Goldspar blanks, with which to make the mast and spars. Originally, I was planning to use the same rig for all three sets of sails,(I've ordered the other two sets), but after reading and seeing what happened at the Champion's Regatta, I've decided three rigs were in order, and so have ordered the necessary fittings.
Nowhere, have I seen mention made about reducing the masts proportionally for the smaller sails, but closely looking over the photos of sail boxes at the regattas, shows that they are. Can't tell if the booms are also reduced in length, though.
In addition, doesn't shortening the masts call for modifying the placing of the shrouds, spreaders, and jumpers, proportionally?
Am I correct in this? Is all this "Common Knowledge" and so not mentioned? Also, can I just use a 12-13oz. lead pig to set the waterline, or do I have to weigh the rigs, and make up a pig of the same weight for each? If the rigs have to be weighed, won't I have to adjust the ballast for each? How is the pre-race tank testing done at regattas?
Any info and opinions, would be greatly appreciated.
Thanks,
