Hi George, I too am redoing my traveller on my M17. The cockpit setup may not be identical to your 15 but after visiting Lenny Corin and seeing his fine "Orli", M17, (written up in "Good Old Boat" mag.Mar/Apr). and discussing his traveller arrangement I decided not to run the traveler from cockpit side to cockpit side. His is that way and he said the level the traveler is now makes it a "pain in the ass" to get into the cabin as you have to step above and over it as well as the companionway sill to then step down into the cabin. I plan to elevate my stock track to just under the companionway sill and thru bolt it to a piece of teak which spans the width of the footwell in the cockpit. That way I can close up eight potential leaking holes where the track is thru bolted through the cockpit sole and give the mainsheet a better run up to the boom than with the stock setup. I plan to install a vang so having to sheet the mainsail in tightly to flatten it should not be a real problem. I am glad I visited Lenny (a real gentleman there) as I was considering running the track right across the whole cockpit. Good luck, Tom B
