Any one built a successful roller ferller. I have seen the plans for pvc ones but am not interested in trying that idea. I have a standard rig and plan to use a 130 jib for the roller ferling if possible.

I love to build things and have a small machine shop in my basement.

A furler isn't something that I'd try to build. The luff extrusions would be very difficult to replicate properly and the head swivel that slides on the luff extrusions would also be pretty tricky to make.

If you can't afford a new system then get a used one. If you are in the Seattle area then contact me, I'm about to pull a Hood 810 furler off of my Pearson (it's coming off this week) and I'd sell it very cheaply. It has the caveat that it doesn't allow for reefing anymore, but it otherwise works fine. My boat has a 1/4" forestay instead of the 5/32" on a C-25, I'm not sure what hardware would be necessary to make the conversion.

I also have the extrusions and drum from a CDI FF sitting in my basement that I'd love to give away. They'll most likely end up in the metal scrap pile.

A furler is something that you need to be able to rely on--the tougher the conditions, the more important it is. The cruder ones, such as those that don't enclose the forestay and leave the luff "loose", cannot be used to reef a genoa, which you may want to be able to do with a 130. (They're more appropriate for a separate drifter in light air.) For a "real" furler, the foil needs to have the correct groove for the luff tape (or "bead"), and the foil must rotate smoothly at the swivel at the top without the halyard connection on the swivel rotating, which otherwise causes a "halyard wrap" that will damage the forestay. I could go on.......

In other words, there are reasons why furlers aren't cheap and cheap furlers don't survive on the market. They get people into trouble at the worst times.

Perhaps you are a machinist that loves taking on challenging projects. If not, I'd take advantage of the offer Alex has above. I upgraded my furler a couple of years ago. Had a new forestay made by a local rigger. Much easier than re-inventing the wheel.

Good luck!

A furler is one of those things that is conceptually simple but difficult to execute. Big bucks engineering took years to get from the first units to strong, reliable systems that were widely accepted.

I've got a very simple furler on my 16 foot daysailer. It consists of a swivel that hangs off the jib halyard and a rotor that connects to the tack of the jib. The jib has a luff wire that runs from the tack to the head.
The jib mounts about 4" behind the forestay, parallel to it.
Having said that I would <b>not</b> advise the same configuration for the C-25.
First, the jib is 100%, not a genoa, so when wrapped it's smaller than a furled genny.
The fore-triangle has a much smaller area than that on the C-25.
The jib usually wraps neatly around the luff wire and does not usually interfere with forestay.
However, when it does, it hangs up and I have to go forward to unwravel it. Pain in the butt.
In high winds (when I need it most) it will often foul, and a large piece of the sail will NOT tuck neatly into the furl, but will flap and flail around noisily and frantically.
It's fine for a nice day in ideal conditions, but in 15-20s with 25 kt gusts, you do not want to use anything less than a precision-made furler. I've been there...

Alex, are those extrusions off an older CDI 4/6 with the three piece foil? I need the torque links that join the pieces. I'd be more than happy to take them off your hands and contribute to the general cleanliness of your basement.

I don't know John, the furler was already in pieces when it got to me (it came with my C-25, but the boat was converted back to hank-on).

If you can tell me how to identify the extrusion I can check to see how many connectors I have.

Alex, they are 4" pieces that join the extrusions together. I broke one this fall when I lowered the mast and CDI no longer has any replacements. I'm running a concurrent thread on the general sailing forum titled "CDI 4/6 torque links" that delves into this issue with a little more detail. I was on that thread making a comment this morning when I happened to notice your comment on this thread about wanting to get rid of extrusions and drum for a 84 Catalina 25. I'm assuming if we are talking about original equipment that you might have the torque links that I need but I'd probably be interested in the extrusions and drum as well. One can never have enough spare parts for these old boats.

Sorry, it looks like DPO held onto those. I just have the extrusions (3 of them, each about 6' long) and drum.

I'm guessing that he put everything else in a bag, then later couldn't figure out what the stuff was and threw it out.

Ah! So close.... Who would of thunk such a small item would be so difficult to find... Oh well... I've still got 4 months to get this issue resolved. Thanks Alex.
