Re: [Cal_Boats] use of traveller

Chris, On Jade (Cal 9.2) which is a IOR designed boat, main traveler adjustment is very important in heavier air. When beating to weather in heavy air, letting the traveler down balances the helm tremendously. This may be more noticeable on a IOR design than the standard Lapworth Cals. Just my 2 cents. Later, Nick From: Chris Campbell <cl… [at] charterinternet.com> Listees: I'll inquire on this list, which has more racers than the list for my other boat. My Cal 20 does not have a traveler (but should). The other boat does. The question is about proper use of the traveler. The other boat has an old one (early '60s) that I'm thinking about replacing this winter because it's very hard to use--lots of friction. I've assumed that you use the traveler primarily to control the amount of mainsail twist. If you sheet the main in and then use the traveler to control the boom position, you can keep an untwisted main that draws evenly (more or less) from top to bottom. When you need to let the main out some, for a puff or for general trim, you just let the traveler down to leeward. If you want a main with some twist so it luffs toward the head and depowers the sail, you can move the traveler amidships or to windward and let the sheet out more so the mainsheet is at an angle from the vertical, pulling down less. Have I got this right? If I'm right, you'd use the traveler to leeward mostly in moderate winds, when you want the perfect foil-shaped mainsail, and you'd pull it back to center or even to windward when you wanted a fuller sail shape in light air or when you really wanted the head to fall off and luff as a means of depowering in high winds. Advice? Chris Campbell

it's also important in the Cal 25. In heavy puffs, we completely drop the traveler to the lower peg and sheet in hard to flatten the main, then ease the traveler back up (slightly sheeting out the mainsheet as the traveler climbs) as the puffs die. In light air, we bring the traveler high, and get better twist in the mainsail.

making it 4 cents--it's a big deal on 27-1's, also. In heavy air, before reefing, I haul the sheet in as hard as it can get to flatten the sail, then play the traveller to ease the helm. Gives me another 4 knots of windspeed before I have to reef. bw ----- Original Message ----- From: Chris Campbell To: Ca… [at] yahoogroups.com Sent: Tuesday, October 03, 2006 6:38 AM Subject: Re: [Cal_Boats] use of traveller ng… [at] comcast.net wrote: Chris, On Jade (Cal 9.2) which is a IOR designed boat, main traveler adjustment is very important in heavier air.

Chris, The 9.2 has boom end sheeting. The IOR design has a short boom with a tall narrow main sail. The traveler is mounted in front of the companionway, making it somewhat in the way for the jib trimmer, but leaves the main trimmer away from the helmsman.

wouldn't a tensioned vang and easing mainsheet do the same thing?

Yes that is true, but on many boats the mainsheet has more purchase, and the attachment point to the boom is farther from the fulcrum than where the vang attaches so it has more advantage there as well. The mainsheet also usually pulls straight down, on a vang some of the force applied is trying to tear the gooseneck off of the mast. Many boats do not have enough power in the vang to keep the leech twist where you want it when sailing close hauled. If you ease the mainsheet it will be hard or impossible to adjust leech twist because the loads on the vang seen by the user are so high. High performance dinghies like the 505 do something they call vang sheeting. They do have enough power in the vang to keep the mast bent, then they can easily and quickly play the mainsheet in and out to keep the boat flat. The other extreme are beach cats. They don't have a vang. The traveller goes across the entire width of the boat. On any point of sail that they normally sail, the boom is over the traveller, so in effect the mainsheet is the vang and the traveller is the mainsheet.
