Off-Season Seminars, Part Two


If you can't get out on the water at this time of the year, the next best way to hone your skills is time spent in the classroom.
In my first article on winter sailing seminars, I extolled the virtues of keeping the rust off your skills in the off-season by attending a seminar in either racing or cruising. Regardless of your ability level, these programs can be invaluable for many reasons, beginning with the fact that they can broaden your knowledge base, reinforce what you may already know, help you unlearn any acquired bad habits, and get you better prepared for the coming season. Now I'd like to get a little more focused and delve into the performance end of the spectrum by taking an example from the North U series, specifically on starting strategy. (See the sidebar for details regarding North U seminars.)

Let's start with an example of a lesson from the North U tactics textbook in Starting Strategy. When I teach these seminars, I always begin by emphasizing the fundamental difference between Strategy and Tactics. The former is what you'd do in sailing around the racecourse in the absence of other boats, and the latter is how to handle boat-on-boat situations.

The incentive for developing a good starting strategy can be huge. In almost any fleet, getting a good start gets you punched into the front of the pack in clear air, ready to execute your winning first-leg strategy. But as Figure 1 shows (below), starts can be chaotic. There can be lots of boats maneuvering in what seems like an unpredictable manner because prior to the starting signal, principles such as proper course don't apply. The challenge here is to distill order from that chaos by having a coherent game plan and executing it in your starting tactics.


The challenge of the start, says the author, is to distill order from chaos by way of an effective and coherent game plan. He uses the above graphic in his off-season seminars to indicate the pros and cons of various positions with one minute to go until the gun.

The elements of devising this strategy are influenced by three principles: the first-leg strategy, the set of the line, and some general ideas described as "making it work." Once the starting line is set and you're allowed in the starting area (remember that in multi-class regattas there may be restrictions on access by classes without their preparatory signal raised) you should be gathering data for devising your strategy. One very simple influence on where to start on the line will be where you want to go on the first leg of the race. If you favor the right side of the course, then start on the right and be ready to tack. If the left looks better to you, then start at the left end and extend out on starboard tack. If you're undecided, then try to start in the middle and be ready to tack.

Another element is the set of the line. Here it's important to remember that regardless of where the mark is, the upwind end of the line is always the favored end. This can be determined by a variety of means, but a few include taking compass bearings of the line transit and comparing them with the true wind direction (if their difference is not 90 degrees, then there is a bias); luffing head to wind and siting down the line (the main traveler will intersect the upwind end); and observing earlier starts. In the case of the latter, if the fleet appears to struggle to lay the line on starboard, then the left end is favored. If you do the math, the incentive for determining this bias is pretty compelling: A boat starting at the favored end of a line biased by 10 degrees will be ahead of a boat starting at the unfavored end by 25 percent of the length of the line!


In mega fleets, there is often some incentive for being in the middle of the line due to the mid-line sag. However, in the shot above, the sheer number of boats should be enough to prompt conservative racers to start elsewhere.
To make the start work, identify the place on the line that you want to be and just focus on being in that zone. You don't have to struggle to absolutely win the pin end to and take advantage of a left-side favored line; just be in that zone and focus on carving out some space for clear air to accelerate. There is also some incentive for being in the middle of the line, which is the "mid-line bulge." This is that elusive few feet of space to leeward of the line that represents the difference in the perceived and actual position of the line transit.

The last element of devising your starting strategy is giving some thought to what kind of approach to make in your final run at the line. There are several types, each with their own pros and cons: the reach out and back approach; the triangular approach (Figure 2); the port-tack approach; and the half-speed approach.


Figure 2: Off-season seminars can offer instruction in various starting strategies. In the scenario above, with 45 seconds remaining until the gun (see red line in upper right hand corner), the yellow and red boat is executing the triangle approach, reaching toward the line with good speed.

The reaching approach involves doing timed runs while reaching along the line and looking for an opportunity to head up into position. While this is simple, you're nearly always at the mercy of others for your final position on the line. The triangular approach is particularly good for light air since the final approach to the line is done with speed as you accelerate up from a reach to close-hauled. The port-tack approach is ideal for more moderate conditions in which tacking isn't too expensive in terms of boat speed, and it can free you to maneuver into a nice hole (if it's available). And the half-speed approach allows you to modulate you progress towards the line while maintaining your position relative to other boats by alternately trimming and luffing your jib. (Rarely should you luff the main, as you'll be prone to slide too far to leeward.) With experience, you'll find that the use of these approach types will vary with boat type and wind conditions. For example, in light air avoid too much luffing or tacking, especially in heavy boats, which struggle to accelerate.

So, devising a coherent strategy before the flags start going up can get you in position to have the ability and confidence to perform in one of the most important parts of the raceóthe start. And remember that once your strategy is formulated to communicate that with the crew so everyone can be in on the act.

A Seminar Sampler

Two years ago Bill Gladstone's well-known series of day-long instructional courses, called Performance Racing Seminars, was revised, expanded, and improved to become North U. This program is one of the best at providing students with a comprehensive yet concise approach to a sport that can be intimidating due to its complications.

Bill has cleverly analogized his instructional approach with a pyramid, where your success in racing is rooted in preparation and boat handling, with boat speed sitting in the middle tier of importance, and tactics representing the smallest (yet often most interesting) fraction of the game.


Sailing seminars can help you polish the fine points of the game as well as review the fundamentals. To emphasize the latter, the folks at North U use the pyramid scheme.

North U divides its content in two parts: the Trim Seminar covers the bottom two tiers of the pyramid, explaining how to make a boat go fast through the water and around the marks, and a Tactics Seminar that addresses how to optimize positioning around the racecourse. These two programs each feature a day-long lecture, and are now available on CD as well as in textbook form. The offerings of the Trim and Tactics courses alternate yearly, with Tactics being the prominent offering this winter. A new day-long Advanced Tactics course is also being offered in several of the 26 locations throughout the US and Canada where the seminars will be held through April.

And for cruising sailors, there is also a North U Cruising and Seamanship course with the same lecture, CD, and textbook format.
