Wow
Hello,
And first, I'm amazed that someone from Harken would give you that kind of it's-never-been-a-problem-so-it's-not-a-problem answer. And second, I'm amazed that I'd never noticed it myself. Though I can say that the newer furlers have a lot more vertical clearance than the older models, and this might be why. Before you go carving that drum, though, you might consider moving the forward lead block forward, so the fleet angle is compatible with the entry. I wouldn't ordinarily recommend this, as it can cause the turns to pile up in the middle of the drum, but it might be the lesser problem here.
Also, is the lead clean laterally? We often see furlers of all brands with the line chafing on the side of the drum when it is full and the loads are highest.
Next, are you keeping a strain on the furling line when setting the sail? If not, the loose turns will tend to jam when you pull hard to furl.
Next, have you rinsed the bearings out lately? Ever? A visual check might be in order, to be sure the balls are whole, and nothing alien is in the races.
Finally, what is your state of tune? A slack backstay makes for a lot more oscillation of the foil, which is of course most significant in a breeze. The same issue could be why you are furling in the first place, as a too-full jib heels the boat, and prevents pointing.
Check back in a couple of days; my favorite Harken tech guru will be responding here as well.
Fair leads,
Brion Toss
