The use of a compass gives you a more objective and consistent approach to calling laylines. Take note of your average heading on each tack while you are sailing up the beat. Then, while you are looking at the mark, use your heading from the opposite tack to judge your layline.
The best tool for this is a hand-bearing compass, which can be worn around the neck of the tactician or other crewmember. Remember that a compass layline is based on times in the past when you were sailing on that tack. However, you need a few conditions in order to make this work:. This method might work well when sailing multiple races on a fairly short course. A range on shore will give you a very precise layline that is accurate when you get it before the race.
But if conditions change very much, that layline sight will be worthless. The angles of other boats tell you a lot about the wind in which they are sailing, so keep a close eye on them while racing.
The easiest way to make a layline call is by looking down the centerline of boats on the opposite tack as you cross behind them near the layline. You can also use the angle of any other boat on the opposite tack to help estimate your sailing angle toward the mark. The boat has 4 minutes to go on port, and 3 after that on starboard. You could tack a few times before you gets to the layline, but the total time on port and starboard will be relatively constant.
But when sailing, laylines are not static. The wind shifts them back and forth, and changing wind speed balloons the laylines in and out. OS5 keeps a history of wind shifts, and attempts to show you the leftmost and rightmost positions the laylines are likely to take.
As the wind shifts between leftmost and rightmost, the current corner moves up and down relative to the two extremes, giving you an at-a-glance view of how close you are to overstanding.
In sailboat racing, calling the laylines is one of the most challenging aspects. If that computed heading is the same as the present CNM then you are crossing the layline. The computation is just a little bit more taxing on your brain when on a downwind leg because the wind is crossing the stern instead of the bow.
Your fastest point of sail is not dead downwind TWA but rather a broad reach When the next mark is a gate or the finish line you must compensate for the fact that the CNM displayed in your instrument panel is relative to the center point between the two marks for that gate or finish line.
You can make use of the in-game camera angle rotation to help with this adjustment. With some practice you'll be doing these calculations with little effort and with even more familiarity you will simply eyeball the angles and surprise yourself at how accurately you've become able to judge the best moment to change course. Don't be tempted to simply rely on following the course you see boats ahead of you sailing.
You may one day find yourself in the lead and because you have not trained yourself to compute with confidence your optimum course you might find yourself in a panic and lose that lead you fought hard to win. When you tack you typically need to sail a few degrees below close hauled in order to accelerate to maximum boat speed.
Therefore you should allow for this when fetching an upwind mark. I recently transitioned back into the venture world from a role that had evolved from startup through successful acquisition and quickly remembered why it's so important to be able to sense and call tacks in small, quickly growing organizations. The same sense of urgency simply does not exist in bigger companies, nor does the ability to quickly affect change. I started this new blog with just that in mind; to exchange experiences and ideas around the concept of identifying laylines and calling venture growth tacks — particularly around marketing and go-to-market decisions.
As my metaphor has developed and I use it to frame conditions and decisions, I feel a real heightened sense of self-awareness and effectiveness. By sharing here, I hope to further increase my, and hopefully your, clarity on these kinds of decisions.
