roller reefer, YES / roller furler, NO
Not being the sailor I wish I was, I'm confused here. The whole point for me is to make the jib smaller when the wind gets up. What's that: reefing or furling? When it's all wound up it's furled, right? So when there's still some wee bit triangle left, it's reefed. If that's not correct it is no wonder I'm not sailing.
338 had a Harken furler that worked just fine and forgave my whambam-thankyou-mam attempts at sailing into the wind. I thought it was great. It must have been a reefer-furler. What would anyone need just a furler for?
Later when I had the gear removed, I noticed the stem fitting hole was elongated. Toward the top. About a quarter of an inch of metal left. I thought it was due to the heavier loads on the fitting. But it's possible the damn fool who attached it rat-tailed the hole to accept the tight shallow strapshackle clevis pin. 5/8" from the bottom of the drum to the center of the pin!! The older I get the more I go round shaking my head.
There is another entirely different furler that looks simple and elegant and offshore. It's by SPIN-TEC. furlers@spin-tec.com
Any chat on it is hard to find. You might try www.sailboatowners,com to see how genuine you think their comments are on this furler. I'm not persuaded, EXCEPT by the concept. Practical Sailor hasn't graded them yet.
