I don't know what loads your mainsail take s but I solved this problem by going back to basic seamanship. Fit an old-fashioned horned cleat. Swig up the main with the kicker,cunningham and outhaul off, take a round turn ,a figure of eight, and finish with a locking turn. You could make a mock up horizantally on a scrap piece of timber. I'll think you will find it won't slip.

I'm going to take a look tomorrow evening and see what the main halyard could be tied off on! The cleat evidently isn't man enough. A horned cleat would probably pull off the mast as soon as the kicker went on!
Another idea is to have a D12 halyard with a loop in the end, then put a hook through said loop and tension it with a 2:1 - halving the load on the cleat. Which is what my V3000 has as a jib halyard - and holds 300lbs rig tension in a v-cleat with no issues.
Btw: most Javs have a simple rope main halyard and it's common for the halyard sheath to strip off the core at some point, mostly 'cause people are too tight to move the halyard along an inch every few weeks. The Jib halyard, which controls the mast rake is indeed wire and attached to a multi-purchase system. Rig tension goes on via the shrouds through lots of blocks and rope (D12 on a modern one). Kicker is 16:1 or 24:1 and cunningham at least 4:1. So lots of force pulling the main down. I've never seen a Jav with any external halyards - tho it seems a good idea. A cleat at the top would also reduce compression on the mast. Probably banned by class rules, in case it makes the boat too modern ;¬) |

Like this (not our boat so not a D12 hal but otherwise same diff)

The aerodynamic drag is the usual objection. External halyards are really only viable on classes where everyone has to have one. |
