Not sure if the CDI will work for that...
I was wondering the same thing last year and did some checking on different furlers for the 26.5 From what I can tell, the boat is designed for a furler model that has been dis-continued. I think it was designed for a Shaeffer furler but I am not positive on the manufacturer. I think I am going to go with the Pro-Furl R25 on my boat as the foil lengths will work and I like the available features. You may just be forced to live with the drum at the deck and not under the deck unless you can find a drum that will not only fit through the hole, but not cause interference when the headstay is attached. Good Luck,ClaytonH26.5s/v Walkabout
