Probably could use a few more pictures. Are the flanges plastic? It seems there is a broken third flange on top? If so, it might be a Cruising Designs (CDI) Reefer I. That would use an internal halyard that cleats of at the furling drum to raise the sail. The Reefer II had a locking mechanism where the boat's jib halyard raised a tool up the spare groove in the extrusion to lock/unlock the mechanism at the top. The tool had an arrow cast into it that indicated which direction to hoist it for raising the sail or dropping it. You have to tie a line to the tool so you can get it and the boat's halyard back down.

No evidence it ever had a third flange; the halyard goes down the mast like most RF I am used to. I believe it is cast aluminum. Years ago I worked on a CDI that was on a Caliana 25.

Thanks for the reply,
Mike

My first guess was a Profurl from the 70’s. They used individual stainless posts outside the drum as line guides. But the tang connection holding the forestay is wrong. Profurl has a sealed bearing beneath the drum.

Fancor also had the stainless post guides, but the guides were in a U shape, solid not individual posts.

Is this a US built boat? What year is it? The style of furler appears to me to be from the 70-80’s.

Is the owner having any issues with the furler or is the question just about identification?

40 year old Mason 43 from Taiwan. We noticed it has a slight hard spot when turning it. Thinking it is probably bearings but wanted to try and find a manual before going further. I thought it was Profurl at first also.

I would guess the probability is that the furler is also 40 years old. The manual is likely to be long gone. Finding parts may be a treasure hunt,

If there is a flat spot on rotation of the drum, I would concur with your diagnosis. These older furlers are pretty simple devices. I would tie up a halyard to take the strain of the forestay, and then see if the drum can be removed from the furler extrusion. I would want to work on opening it on a bench where you can take pictures as it comes apart and then put it back together.

If it is a Profurl then the bearings were in a sealed race. They are not ment to be individually replace. I understand from my rigger that it can be done, but the opening is a challenge I decided not to take. I replaced my Profurl with a Harken after a series of issues that happened.

Good luck. Let me know what you find.
