Well OK, but only cuz of the sugar & spice!

Actually, I don't have any detail shots showing the mainsheet system yet...but here is a link to a shot of the boom proper:

Boom



My setup is basically identical to this:



Only that one uses custom carbon block plates. We have a standard Harken single ratcher w. becket for the lower and another off-the-shelf wire block at the upper. One sig. diff. is that my upper is just a single block without a becket, so I do not have the third blue line coming down to it like this example. I have not dismantled the internals yet to see exactly what's inside...but the two outer turning blocks at the aft end are homemade/custon delrin sheaves...large diameters (& kinda heavy) with lubed bearings turning on 1/4" bolts. The whole boom weighs about 2.5 lbs (~1 kg) less than my quad block setup...that's huge!
