Hi Chuck, I installed a CDI FFI furler on my M- 15. It requires you to replace your forestay with one including toggles and a turn buckle of the open type. There is no jib halyard. Bring up the CDI manual on the internet and read every word. Then read it over several times more , paying particular attention to article 7 of the POST INSTALLATION WARNINGS AND SAFETY CHECKLIST. I am emphasizing a thorough study of the manual because to me it is not particularly instructive as written and you do not want to make mistakes.Shop on line for the furler.A good deal is about $315. I got a 150 genoa from National Sails dealing with Dirk who knows the boat . The whole expense was less than $1000 and you can easily sell your current head sails to lessen the cost.. I am 100% pleased with the change from hank on to to the furler,especially as I can shorten the head sail when need be and still maintain its shape.Today marked my 30 th outing this season and the change has proven a boon to this 83 year old. .Good luck.
