Phil Do you have a part number? And, you have a 270; is it the same for the 27?

Braided lines take force to move all those fibers past each other to bend around a sheave. When a line get upsized they have more fiction points (more fibers) and that have to move further to bend. So just going from 5/16” line to 3/8” can make operating the halyard a lot more work. Wing Tip’s main goes up all the way by hand but it wasn’t always so. I replaced the sheaves in the Garhauer deck organizers with Harken ball bearing sheaves. They look stock but perform much better. In fact every single block on Wing Tip with the exception of the ones in the mast are now ball bearing blocks.

So it spins with no load and locks with load. How old are they and do you know if they have ever been changed - from my experince and others on this board it is clear the original have a finite lifespan.
