Inside or Outside tracks for sailing the genoa. I am curious as to the collective experience of the T-37 sailors about use of the inside jib tracks vs. the tracks on the toe rail. I have routinely used the tracks on the toe-rail for sail trim on our 135% genoa and felt that the use of the inside track seemed to close down the slot and choked off the sail performance. On the occasions that we have used the inboard tracks we have been able to point higher but it seems that we are closer to pinching which slows the boat speed. I suppose that the controlling factor is the width of the outermost shrouds; if wider, it will prevent a good fairlead on the inboard track. Also, I wonder whether any of the T-37 sailors switch from the inboard to the outboard sheeting when off the wind.

I would like to learn others' experiences concerning inboard vs. outboard sheeting.

Thanks,
J.P. Anderson

Use the inboard tracks for upwind and most sailing. The outboard tracks are great for off the wind sailing. Upwind you should have a bubble in the luff of the main.

With new head sails don't over tighten the halyard, should look like soft scallops in the middle 1/3th of the sail. Only tighten it up in heavy air.

Go upwind and set the cars. The sail should break even, you should have telltails about a foot aft of the luff for this. If the telltale at the top of the sail luffs first, the jib lead should be moved forward. If the bottom telltale luffs first, then move the jib lead aft. The sail should be close to parallel to the leeward shroud and keep the leeches of the main and headsail close to parallel. You really need to get on the main sheet of a T37 and be certain to center the boom.

In heavy air move the cars aft to open up the sail and depower the headsail.

Move the jib lead to the outboard tracks to open the slot between the ginny and the mainsail when sailing off the wind. The outboard sheet leads should be move forward about 6-inches to keep the jib telltales flying evenly.

We move from outboard tracks to inboard all the time. Anything from a beam reach to a run, we're on the outboard tracks. Pull the lazy sheet around to change without tacking.

Thanks for that explanation. I was watching this question from JP since I've often wondered those same things. Zach
