Steve, I had the same problem on our 1991...
P42. All eight clutches were in use when I added the spin halyard. I had to move the outhaul from inside the cockpit to a mast cleat to free up a clutch. So, from port to starboard I had the topping lift, spin halyard, reef two, genoa halyard, boom vang, reef one, main sheet, and main halyard. I wanted to move the outhaul back into the cockpit to make trim changes. So, I moved the topping lift back out to the mast cleat to free up a clutch for the outhaul. Since our boat has the Dutchman flake system I needed to be able to either tension or release the topping lift, which is why I had it through a clutch in the first place.Rather than run the topping lift into the cockpit through a line clutch I tied the mast end off at the mast cleat and added a double purchase block arrangement at the end of the boom. In order to make it work I installed a single three inch turning block with becket on the end of the topping lift, and a single three inch ratcheting block with becket and cam on the end of the boom. This block configuration gives me the purchase I need to lift the weight of the boom from the cockpit while the cam holds the boom up when the main is down. Once I raise the main I can quickly release the topping lift to allow for proper main shape. The alternative was to add a nineth line clutch and a nineth line organizer (double row...not sure it would fit under the hood) at considerable expense.If you adjust your topping lift from the cockpit now, this is a way to free up an organizer and line clutch.
