Mainsheet block kit for the Capri 14.2 and Capri 16.5. The two blocks at the top of the photo mount on the boom. The one on the top left includes a becket and mounts at the aft end of the boom. The bottom "sistered" block mounts on the boat. A short traveler line is secured to the aft corners at the transom. This traveler line passes through the smaller of the two sistered blocks. The mainsheet passes through the larger of the two sistered blocks. The standing part of the mainsheet is tied with a bowline to the becket of the top block.
