Re: Easing the Mainsheet
That cleat on the boom appears to be poorly placed. It appears to be situated about where a turning block should be located for the second reef. I would relocate it on the boom near the mast. That cleat looks like it's for your outhaul. I would suggest you enlist someone with some experience to help you re-position that cleat, and to re-rig your reef lines and hardware. C&Cs are good boats, but it looks like a previous owner has tinkered with the rigging hardware. It shouldn't cost much to make it right, but you could probably use some help to position the hardware correctly.
