Jerry I have purchased an M15 I was looking at modifications to improve Sailing. Coming from larger boats (last one Pearson 23 CB) I am accustomed to using a Traveler System. Looking thru the various projects on the Montgomery site I came across your contribution on the M17 system you developed. I have a couple of questions that you might be able to answer for me. 1. Should I continue to use the Main Sheet set up on the M15 (yoke at stern) or go full bore and convert to a 4 part mid boom Main Sheet directly to the new traveler? 2. I have searched the Ronstan web site for the parts you have listed but they do not come up. I suspect that there has been a change in the numbering system since you published the information. Do you have any recommendations as to how I can find the parts you recommend since there was no physical description of the parts? 3. I did a quick total on the costs of parts that I think might be right and they are approx $300 less line in today's boat $. Of course I have not visited a marine consignment shop to see what I can get to help keep the $ down. I see that the Harkin Small Boat Windward Sheeting Car is $319 I believe all I would have to add is Track @ about $80. So @ $400 do you think it worth the extra $100 for the Windward system? 1998 M15 NoNameYet Valpariaso Indiana George We can not control the Wind But we can adjust our Sails
