Re: Should a Roller Furler be Hard?

Why is it that people buy harken instead of Pro Furl?

With pro furl no halyard wrap; no lubing, no rinsing. No muss. Mines 20 years old and still going strong.

Just wondering?

Speaking only for the Harken MKIV, there is no need for lube, the bearings are self cleaning torlon. The Harken MKIV also comes with a retainer or deflector and should be installed to prevent the wrap Rinsing it with fresh water once and a while, how is that laborious? I just shoot some water in it when I rinse the boat.

I can tell you why I choose the Harken over Pro Furl, the PF = "Sealed ball bearings are packed in grease, eliminating any risk of corrosion and making them impermeable to impurities such as water, sand or dust." If that seal is compromised, the bearings will corrode, I am pretty sure those are steel BB they use but not 100% certain.

Add to that, Harken makes everything in the USA, when I can I am going to purchase USA made products.

There are plenty of 20 yr old Harken units as well

Nothing wrong with Pro Furl, Schaeffer, Furlex, Harken, etc...each have their own selling points. I really think its just a matter of opinion when its all compared.

Re: Should a Roller Furler be Hard?

can also be a lead issue. Go up on deck make sure your furling line enters the drum @ 9o dgrs. Then have someone unfurl the sail while you manually lead the line into the drum at 90 DGRS. After the sail is out have your mate ease the sheet all the way out. Then grab the furling line at drum exit and hand pull @ the same 90dgrs. but pulling out. if all operates smoothly then you have furling lead issues. If it doesn't operate smoothly you may look up to see if halyard is wrapping. 3 things that can cause halyard wrap.
1.halyard tension to loose try tightening it up
2. halyard lead to exit box as mentioned earlier
3. worn out upper swivel I've seen them work @ deck level but when hoisted with tension on the the bearing can jam. to check this lower swivel to deck Check if bearings grind when turned or excessive wiggle when rocked back and forth

This link to the instructions for the MK4 unit has lubrication instructions on page 31. Not too different than those for my MK2 unit except mine suggest using WD40. I suspect McLube wasn't available then.

Re: Should a Roller Furler be Hard?

Good catch Jim, oddly though in the Unit 2 manual ( the type on my boat) it doesn't specifically state to use any lube (McLube to be specific) although it does show a photo of what looks like lube being applied? Weird, I do not recall anything in my manual on the boat saying anything other than soapy water rinse twice a year.

"CleanKeep unit clean. When you wash boat, flush unit with soap and fresh water.
Occasionally lower sail and flush halyard swivel with soap and fresh water.
Clean unit more thoroughly at least twice a year. First remove line (note
direction on spool) and flush bearings with soap and fresh water.
Clean foils with soap and water"

Re: Should a Roller Furler be Hard?

Another possibility is that you may need additional tension on the backstay. Insufficient tension allows the foil to sag givinga more difficult motion requiring more energy.

I bought my Harken IV for the same reason as T37chef. I liiked the idea of not having a sealed bearing systems. My old Profurl rusted at the bearing case and compromised the seal.

I also found the Harken furls the sail equally, while the profurl did not. Both are fine units.

Re: Should a Roller Furler be Hard?

One other thing I would check here is the angle of the furling line to the first sheeve or block. It may be why in the beginning the sail furls easily as you are pulling from a full drum, and as the drum empties your angle may be more acute and dragging.

Also when you let your sail out keep some pressure on the furling line as the drums fills up to insure more uniform overlap

Re: Should a Roller Furler be Hard?

I've found that enough tension on the stay is critical. If there is too much headstay sag, you are trying to roll along a curved surface. Just a little more tension can make a big difference. Also make sure you don't have too much line on the drum and that it is leading into the drum at an angle, as Chef said, that will distribute the line evenly and not cause a lump of line in one spot. The line can bind if the overlap is not relatively even.
