If you have your heart set on a CDI Flexible Furler. Pick the FF6. I believe it is the largest they make and none too big for a Columbia 28.I am looking into a roller furler for my Columbia 28. This is a masthead sloop. The I & J measurements are 31.8 and 12. With that I calculate my headstay length at 34 feet and the stay diameter is 3/16".
Looking at CDIs recommendations, they list the FF4 as a maximum stay length of 33' and the FF6 as 39'. Right out of the gate, we are at the fourth largest furler they make.
I'm a little surprised at this as I don't think this is a very big boat. Am I missing something here or is this really the right size furler for a 290 SF 150% Genoa?
Do you trailer the boat and have a need to drop the mast often?
