I suspect this question may have been addressed in the past, but what the hey, it's always good to get some fresh insight, right?I want to install genoa tracks on my H23 (the previous owner was happy with just the 110 jib). Any suggestions on brand? Are the cars with the control lines to the cockpit worth it? I am just cruising for now.All the genoa tracks that I see in the catalogs fasten to the deck with self-tapping machine screws (#10 I believe) spaced about 4 inches apart. I am a bit wary of self-tapping screws, because the jib-lead tracks on my Missile (16 ft. two-man planing dinghy) are through-bolted, and if you have to do that for a smaller boat....If the machine screws are OK, do they go all the way through the deck and penetrate the headliner? I hate having holes in the headliner because no matter how well you seal or caulk, they will eventually leak. The cabin is very dry right now and I'd like to keep it that way if I can. Thanks for your help.Peter Suahs/v Raven
