after 6 hrs of racing my suncat my arms are exhausted.don't know if its from the angle that the mainsheet comes out of the block.or just the heavy load that the 150 sq ft sail puts on the main sheet.the wind is real tricky on the lake.constant sail adjustment tires me out and leaves me with throbbing pain in both upper arms.am i alone in this or is this a common problem,or am i just a wimp.who need to get back in the gym.
So any high effort arm use can be reduced by adding an other purchase. [Look it up in the dictionary] in short add another turn with a 4 purchase pulley system. Lots to choose from. skip.
If you're in a situation where you have to hold the mainsheet, rather than cleat it, such as in stormy/gusty weather, a Harken hexaratchet fiddle block can greatly reduce the load you have to hold. It has a slide switch on it that either lets the large sheave rotate in both the hauling and easing directions or rotate only in the hauling direction only. It's available with becket for 4:1 mainsheets (http://www.harkenstore.com/uniface.urd/scpdinw1.ShowProd?B4RPMEB9Y8U1XS) or without becket for 3:1 mainsheets (http://www.harkenstore.com/uniface.urd/scpdinw1.ShowProd?B4RPMEB9Y8U1XO).
That is pretty close to the gear [in the pictures] I use to cleat down the main sheet on the C-P 19. Works well. skip.
