for something different in masts...
Speaking of variety in masts, my '86 h23 has a "France" mast with 36" spreaders, which makes three known brands. Not knowing any better, I followed the instructions in the manual on tuning the rig (Mikey, if you can't get one from Hunter, call me at 541-345-2802, during working hours, I'll fax or copy and mail you the manual). The manual states, in part, set headstay turnbuckle at 1/2 open, then tighten backstay to medium tension. Starting with slight tension on uppers and lowers, check to see that the mast is centered athwartships by hoisting a steel tape to the masthead and measuring to the chainplates. Then tension uppers equally counting turnbuckle revolutions, until you have approx. 1 inch of pre-bend fore and aft. Now tighten the lowers evenly, counting turn buckle revolutions, sighting the luff groove to ensure the mast remains straight athwartships. Then tighten the backstay to a taut postition, about 8-10 turns. Personally, I crank the forestay in 3/4's of the way, and rely on the backstay adjustor for further fore and aft adjustment of the mast as well as controlling draft in the sails. The France mast is just as bendy as the Z-spar. The manual suggests test sailing in 10-12 knots, sighting the luff groove for straightness, and that the leeward shrouds should not be loose. More or less following these directions has worked pretty well for me. Jim Kolstoe
