Last weekend, for the first time, I climbed to the top of the mast of my ’83 standard rig C-25. I noticed that the top of the roller-furling unit was about 18 inches from the top of the forestay where it attached to the mast cap. When I bought this boat last summer a friend remarked, “Oh, I see you have a deck sweeper.” He was referring to how the jib was attached down close to the deck. I had never heard the term before, but I think that I am remembering it correctly. At that time, looking up from the deck, it did not appear that there was any possible adjustment. My roller-furling drum must be attached directly to the bow fitting. Is that correct? Or is there supposed to be something in between the bow and that drum? Is there a fixture, an extension, or another fitting that that could or should be installed to raise the roller-furling unit? Is there any benefit to raising the jib a few more inches above the deck – it would better clear the bow pulpit when not quite close-hauled. Or is there a reason to keep the top of the furler 18 inches away from masthead or the mast cap? Or, maybe it is exactly the way it is supposed to be and having a “deck sweeper” is perfectly all right.
Dan, We would need to know what brand furling-unit you have to answer the question. I know a CDI that is 18" below the top of the forestay can be a catastrophe waiting to happen. Pictures would make for a much better informed discussion. At the very least the brand name should garner you some informative responses.
Dan, Joe is right, the brand does make a difference. We have a Harken 00AL and the distance from the eye in the forestay pin to the shackle for the sail head is only 9". So if it is a Harken you have double what is indicated in their manuals.
I have a CDI and it has a fitting at the top that spins on the forestay, It should be on the swage if possible so it does not wear on the strands. Forestays have failed from that, but that does not mean you are in eminent danger.
I have my assignments - when I get back out to my boat I'll get the make, model and serial number from the base unit. I'll try to take some picture as well - of the lower portion (I doubt I'll make a solo ascent with a camera at the moment). Then I'll have to learn about posting pictures . . .
Dan When I rigged my furler I was told by Harken to keep the upper swivel within 6 inches of the stay eye to prevent halyard wrap. They and Gary Swenson at Ullman also warned against raising the drum and sail too far above the stem as this would increase heeling. Since I cut my foil too short I did raise the drum off the stem about 3 inches with chainplates to keep the upper swivel close to the top. I've seen big boats with drums way above the deck. You need to keep in mind the luff length of the biggest sail you will have on your furler. Hope this helps.
