How tight should the shroud cable be on the hobie cat 16?

Also is it a good idea to pull soap on the the main sail to make it go up and down easier in the mast?

I've heard there is a teflon lube or something that they suggest you put in the track to make it go up easier... I'd be interested in hearing/seeing the specific product..

Shrouds should be TIGHT on the Hobie 16. This is done by tensioning the jib halyard. Loose shrouds mean a loose forestay (Jib Luff Wire IS the forestay). Loose jib luff wire makes upwind sailing less efficient.

Soap will attract dirt and grime with creates more drag over time. I prefer a dry lube or just a clean luff rope and luff track. Silicone spray #5106

Biggest issue with the H16 main is the large amount of luff curve in the sail. That wedges in the track if you pull too hard on the halyard. I have a hoist FAQ.

Quote:
Several factors can cause the mainsail to be difficult to hoist:

Dirty luff ropes and luff tracks. These can be cleaned with soapy water and a scrub brush. If you want to use a lubricant, keep away from oils and waxes that can attract dirt. Use a dry silicone spray. Most all Hobie sails now have a Teflon threaded bolt (luff) rope to ease the hoisting effort.

Battens and sail shape. The battens stiffen the airfoil shape of your sail. Over tensioning of the battens can cause a couple of problems. Luff protector caps can be forced against the mast and cause drag when hoisting. The battens also force the sail shape into a curve. The luff curve (seen when laying the sail out on the ground, as a large arch) is typical to Hobie Cat main sails. The sails "airfoil" shape is mostly created by the miss-matched mast bend and luff curve of the sail. The luff curve is more than the likely mast bend and when the mast is straight (while hoisting) the difference is dramatic. This luff curve going up the straight mast can cause significant drag and hoisting problems when done incorrectly.

Outhaul. Be sure the outhaul is fully released before hoisting.

Hoist Technique:

Keep the batten tension to a minimum. Hoist the sail slowly, while feeding into the mast opening. When the sail gets about 3/4's of the way up, begin aggressively feeding at the bottom opening and reduce the amount of halyard effort. If the halyard is pulled tight when the sail is not being fed into and up the track, you will have problems. The sail luff will pull taunt and the curve shape will bind in the (straight) mast track. Lower the sail slightly and begin feeding again.

The best way to feed the sail is to stand in front of the mast and reach around either side to "sandwich" the sail between two hands (above the feeder opening) and push the sail up the track. Pull with the halyard, only the slack created, then feed again. If the sail binds, lower slightly and begin feeding again. This technique can be done by one person, but is certainly easier with two working together. It is VERY important that the person on the halyard only pulls the slack up the mast and does not get ahead of the feeder.

Sailkote by McLube. They don't really say whats in it though. Probably silicon. Teflon is an electro-chemical bonding process. You can't really spray it on anything (or rub it on your car, add it to your engine oil etc). "Teflon" additives to products are mostly marketing hype.

I rubbed paraphin wax of the track of the mast and on the luff of the main and it flies right up now.
