I don't recall exactly what kind of boat Flight Risk is - but you can cut mast compression loads in 1/2 by using a beach-cat style hook and ring at the top of the mast. You can probably adapt any of the regularly available bigger cat systems; the Nacra 20, the 6.0 (I think they're the same...or were) or have something fabricated - it's not a complicated system. Leave your clutch or put in a spin-lock style clutch that will still permit you to hoist as needed, but use the ring to carry the sailing loads saving not only the wear on the halyard but the need for an exotic line for the halyard as well.
