CDI furler
I had one on my old boat an ODay 30. It worked well but note that the directions say It can be put on in a few hours. It took me one day with help. Secondly, the spool on the system sat very low on the bow and made it hard to access the anchor on the roller. I had to use an attachment (like a tang) to raise the system and increase the height from the deck. I ordered their largest furler and added in the optional bearings in the roller spool. In using it I never had any problems in 5 years. I purchased it because of the simplicity, and I did not have to cut forestay and the lifetime warranty.
