James, Tinho developed a great outhaul pulley system that bolts through the clew ring and stays with the sail. for some folks, raw spectra is slippery enough if one only uses 2 passes thru the clew.
yes, one can adjust the D/H to gain some, but one must recognize that too little tension has no pay off and lots of costs.Īlso, using spectra line for the grommet portion of the running rigging is an option too. It's like the adjustable on the fly down haul that RSX folks use: too loose and the batten tips are broken with very little pay off. so, in summation, pumping with zero out haul tension is a waste of energy, and can wear the gear out sooner. the sailors' energy is wasted, and the running rigging gets far more wear. When pumping, the up and down movement of the back of the boom versus the clew grommet is my concern, not the port or starboard drift when the out haul is loose during a straight run once locked in and planing. So in OP conditions when I need stability, I outhaul completely and the clew can't move, and in UP conditions when I want the sail to inflate and pull in the gusts, the extra movement is actually a good thing. And I set things up so when I'm outhauled to the max, the clew block is "captured" by the boom. To me, the lines never moved very smoothly through the burgers, and the block gives me a much better feel for outhaul pressure. I'm on carbon on the big sails, so the slightly longer boom length does not compromise stiffness - and I don't think the fact that the clew can deflect off to leward hurts (or even really affects) the sail geometry. I don't think this hurts the performance, though. That arrangement does make the boom slightly longer than with the burgers, because, like the downhaul hook you're using, the block is aft of the clew grommet, as opposed to directly adjacent for the burgers. I attach it to the clew with a bow shackle, which makes for a very quick and very secure connection. I quit using the burgers a couple years ago in favor of a Ronstan double block.
if you loosen during a run, always balance your trim just before or during your sail transition. also, don't go slack on your outhaul into transitions. should have nothing to make the boom longer than it needs to be. James' Blog: Windsurfing Equipment Size Calculator Has anyone else notice an effect of different kind of clew pulleys or outhaul attachments on sail performance? The Ezzy Cheetah 9.5 is kind of a "squishy" sail to begin with, so I don't want to introduce any additional wiggle that might reduce its efficiency.
The other thing that I've just gotten concerned about after looking at some of my clew-mount camera footage is how the pulley hook might be allowing the clew and foot of the sail to twist and flap more than they would otherwise. It makes for very easy rigging- even easier rigging than a fixed outhaul system -but I'm concerned that it might come unhooked sometime when I'm sailing, though that hasn't happened yet. Posted: Mon 12:43 pm Post subject: Clew Grommet "Burgers" for Adjustable Outhaulĭuring a few year long hiatus from formula windsurfing I got rid of all my >8.0 sails and most of my jumbo sail accessories, like the little pulley-burgers that you screw into your clew grommet to make it work better with an adjustable outhaul system.Īs a cheap alternative for my new 9.5 I've been using a downhaul pulley hook.
