I am considering a furling head sail for my H22. Can anyone provide the exact dimensions I need? Is it roughly the same for a Cat 22?I pulled this off the Sail Warehouse web site: (this sounds too complicated... need to climb mast?)"First you must establish the headstay profile of your boat including the “pin to pin” wire length, wire diameter, turnbuckle screw diameter and clevis pin diameter. For most units you must actually measure the “pin to pin” length by ascending in a bosun’s chair and measuring from the center of the clevis pin at the mast head all the way to the clevis pin center at the stem fitting on your bow. This dimension will include all turnbuckles and hardware on the wire. If you call with this information we can tell you which units will work on your boat."I have been looking around on the web and have found a FF2 w/ 155 for $820 at sail warehouse but this is listed for a cat 22. Any others have a better/cheaper idea. I hope to find someone who has just completed this upgrade and can provide some help with lengths and best prices.Thanks so muchMatt
