Shifting gears



The different gears

We will first define and name several different gears and later explain when one should use these gears to get the most out of a boat.

1. Normal Mode
This will be the gear that we use as a reference, i.e. backstay looser than normal, sheet eased more than normal etc. Normal mode could be defined as the settings used when there are no other boats to worry about, steady winds, tides and flat water. When sailing your optimum VMG upwind you must find the perfect balance between sailing high and sailing fast. This setting is usually used in about 8-12 knots of wind or when the crew just starts to hike. The genoa leads should be set so the bottom and top tell-tails break evenly and the sheet should be trimmed just hard enough to maintain a constant speed. The genoa halyard should be set so the draft of the sail is between 40-45% aft of the luff. The main should also be trimmed so the boat speed can remain at a constant speed without much effort. The traveler should be nearly center-lined, the sheet should be tight enough so the top batten is nearly parallel to the boom and the outhaul fairly tight. The backstay will be in a medium to tight setting depending on the wind.

2. Two Sail Reaching
Most races start out in this mode during the pre-start. Make no mistake, it is just as important to set the boat up for maximum speed before the start, as it is once your are on the racecourse. If you can carry good speed into all of your pre-start maneuvers you will have more control of the boat's position when the race starts. Set the boat up with a headstay that is about 30% looser than your upwind tension for the given conditions. Move your genoa leads forward 4-5 inches to prevent the top of the genoa from twisting off too much. Ease the halyard slightly from your upwind mark. No matter how strong your Genoa halyard is it will stretch as you begin to harden up onto the wind and trim the sail in. Easing your halyard when not sailing upwind will also make your headsails last longer. Typically, when reaching back and forth, the traveler is centered. When the traveler is centered, the boom vang should be tensioned until the top and the bottom of the mainsail begin to luff at the same time. If you have a choice of tacking or jibing, try to jibe to minimize the loss of speed.

3. Power Mode
Power mode is the mode you use when sailing in bad air from another boat on the racecourse, light air, or choppy seas. Typically the rig setup will be a looser headstay and tighter checkstays. The Mainsheet should be set up with a higher than usual traveler, the leech must be open so the top batten has about 3-5 degrees of twist. The outhaul should be set slightly looser than normal in order to maximize the sail's drive. The headsail should be set up with the leads forward, the halyard slightly eased and the sheet 2-3 inches looser than normal.

4. Point Mode
Sailing in point mode is one of the most difficult to sail in since the groove is very narrow. It is critical to compromise only 1 or 2 tenths of a knot of boat speed so that the keel continues to work. If you try to higher, you will lose more in boat speed than you will gain in height, as the boat will start to slide sideways. It is very important to maintain a steady speed. When switching to point mode, the first adjustment is to tighten the backstay. Then the mainsail should be trimmed to give the driver more helm. Start with the sheet trimmed tight (top batten 1-2 degrees beyond parallel to the boom, or tell-tails just stalling). Move the traveler so it is at or just above centerline. The boat speed will not hold steady for too long so try build speeds by easing the traveler not the mainsheet in order to reduce the drag of the sail. The genoa should be trimmed with the halyard tight, the lead moved aft and the sheet on hard. The sail should be into the top spreader and the lower shroud. This, combined with a tight headstay, will flatten out the headsail significantly. Do not ease the genoa sheet to build speed if the weather tell-tails are luffing. Rather tell the helmsman to fall off then ease slightly.

5. Light Air Wave Mode
When sailing in waves and light air you should generally try to sail your normal speed numbers and sacrifice a little height. Do this by sailing with the boat slightly heeled and the sails set for a big groove. Ease the backstay a little to allow a wider entry on the genoa and a more powerful mainsail. Trim the mainsail with the traveler high and the sheet and outhaul eased for power. Sheet the genoa with the leads forward and the sheet and halyard eased to give the genoa more punch.

6. Heavy Air Wave Mode
Just as when sailing in waves and light air, in a breeze you should try to sail with your normal boat speed and a little less height. It is very important to make sure the helmsman has a very forgiving groove to both steer over the waves and have the ability to build speed quickly. Do this by twisting off the top of the sails. Make sure the backstay is tight to reduce any slop in the headstay. Sail with the main traveler higher than normal in a breeze and the sheet eased. Trim the genoa with the leads moved aft, the halyard tight and the sheet hard on the bottom and twisted a little more than usual up high. If the mainsail is twisted and the genoa is tight, the boat will never achieve maximum speed, try to always sail with the leeches of both sails twisted evenly.

7. De-powered Mode
Once the crew is fully hiked and the main trimmer needs to start luffing the main to keep the boat from heeling too much you need to start de-powering the boat. Do this by first sailing with the backstay as tight as it will go. Then trim the genoa with the leads aft, halyard tight and the sheet tight. Tighten the outhaul as tight as it will go and start to use Cunningham to flatten the mainsail out even more. When looking for height, sail with the sheet loose and the traveler high. When a puff hits, ease the traveler until the sail begins to luff, try not to let the all of the sail luff except the leech where the battens are. When looking for more speed, trim the sheet a little harder and ease the traveler as low as it will go, before the mainsail begins to luff. When a puff hits, ease the sheet as much as possible without letting the battens and leech luff.

8. Speed Mode
When you are less worried about height and more worried about sailing fast you need to set the boat up for maximum speed. Do this by easing the backstay 20%, and putting the bow down 2-3 degrees and hiking extremely hard. Trim the headsail slightly loose, with the lead just slightly forward. Ease the mainsheet a little and then lower the traveler as far as possible without luffing the mainsail. This will allow you drive off and let the boat sail fast without producing too much helm.
