Fiddle block with cam on traveler
The original C-22 main sheet set up is a three to one purchase on the boom end utilizing a single block with becket on the boom and a double fiddle block with cam cleat mounted onto the traveler car. I found this arrangement difficult to release and secure the main sheet as the fiddle block on the traveler flops around a lot when the wind is light and you have to be close to the fiddle block to properly use the can cleat. In addition, I found the three to one purchase excessive for end boom sheeting on twenty-two foot boat as it is slow and dumps a lot of sheet into the cockpit when close hauled. I think you will find you only need a two to one purchase for the main sheet. Specifically, the fiddle block on the traveler should have just one block with a becket and cam cleat. The boom block just needs to be a single block without a becket. Run the sheet from the becket on the fiddle block on the traveler up through the boom block, then back to the single block on the fiddle block and out through the cam cleat. This will reduce the amount of main sheet falling into the cockpit by a third and in a certain fashion speed up the main sheet action by a third. However, you still have a fiddle block flopping around on the traveler and the need to sit aft to manage the cam cleat on it. On my C-22, I mount a swivel cam cleat with a single block on the forward cockpit wall on two 3/4 inch pieces of that Starboard plastic marine wood right behind the keel winch. (For descriptive purposes a barney post affixed to the side of the cockpit instead of to the floor.) From here the main sheet travels up to the boom through a single block mounted roughly amidships on the boom. The main sheet then goes through the sheave of a single block with a becket at the boom end. The main sheet then goes down to a single block mounted on the traveler and then back up to the becket on the boom end block. In this way, I acheive several desirable ends. First, it is a two to one purchase by having the becket on the boom end block. Second, there is only a single and light block on the traveler that is usually held upright by the 180 degree bend of the main sheet from the boom end block. Third, the cam cleat for the main sheet is superbly positioned for quick and simple action especially with the benefit of the swivel that positions it to weather or the side you will probably sail on. Fourth, you keep more weight foward while working the main sheet. The disadvantage of the sheet running vertically across the cabin opening is barley bothersome as you and crew will be in the cockpit 99.9% of the time.
