During my brief ownership, I noticed the rolling furler line size was wrong. I have the stock CDI roller furler on my 1983 Cat25. Does anyone know the length and diameter of the line used on these.
(the replacement that is on there is oversized and jams easily)
John, the cdi furler is different between the C25 and the C250, you might ask there.
On our C250 (2005) we have the CDI furler and the line pretty well fills the drum when the 110% sail is fully furled. We purchased a 150% sail (used) and I was worried that there would not be enough room on the drum for the extra line required to furl the bigger sail. I called CDI and they suggested that I withdraw some of the inner core of the furler line, I suggest that you call CDI directly, they are very helpful folks, they called me back the same day.
According to the above link - Here's what CDI says is applicable for the CDI Flexible Furler 4/6:
"Furling Line 1/4" braid on braid dacron. If you prefer a larger diameter, you should de-core the portion of line forward in the cockpit. (Otherwise the larger line won’t fit onto the furling drum.)"
I believe that is the line size I used when I replaced the line for furling my 150 Genoa. I will have to check the line size when I go back to the boat which should be tomorrow or Thursday.
After thinking about this subject awhile, I reviewed the information again. <u>Be sure </u> to check which furler you have. If it is the next size smaller FF2,or possibly FF1, these use a 3/16 dacron line. About 10 years ago I purchased 1/4" replacement line which was too large. I believe the correct size will turn out to be 3/16, sorry. Check the CDI manual listed in the Manuals & Brochures to the left of the forum. It is a copy of an early (pre'06)manual.
I was down to my boat today and checked the furling line size and what my CDI Pamplet indicated. My line is 1/4" and it worked for me with a 150 Genoa. The manual I have from PO is a July '94 CDI 4/6 Manual. The specs indicate 1/4" furling line but the write-up in the section covering the furling drum/furling line install states a 1/4" or smaller line is recommended. My thought is that if you want to ensure you can get enough line on the drum for a 150 Genoa and are hesitant to go with the 1/4" line, you could go down one size. That should be fine. Only negative is that sometimes when the wind is blowing and you have to take the 150 Genoa in, best to wear gloves and especially with a smaller line. Otherwise, it is likely to do a number on your hand. As far as strength, the lines these days are probably stronger than lines made years ago. The lines are more high tech these days unless you go the extremely cheapy route. Even so, the line is probably going to be strong enough even if a size smaller than 1/4".
