The buoy is just a few hull lengths away, the boat is heeling to the limit, and another sailboat is right on its stern. It’s in this short stretch that a race can take a dramatic turn. Knowing how to round a windward mark It's not just about taking the right turn: it's about entering it with control, maintaining speed, and coming out ready to attack the next stretch.
The windward mark marks the end of the upwind leg—the leg where the boat sails up against the wind. Normally, it should be rounded on the port side; that is, the mark is on the left side of the boat during the rounding. It looks simple on the course diagram. On the water, however, gusts, waves, opponents, racing rules, and the need to quickly switch from a tight sail to a looser one all come into play.
What Makes a Good Outline
The most common mistake is to view the buoy as the destination. It isn’t. The real destination is the exit from the buoy, on the correct course and at the necessary speed for the next leg. If you scrape past it, almost at a standstill and forced to make a sudden course correction, you’ve completed the course, but you’ve given up precious meters.
A quick tack begins before the buoy zone. You need to decide which side to approach from, check who has the right of way, anticipate the turn, and prepare the sails for the change in course. The less you have to improvise in the final seconds, the faster the boat will accelerate after the maneuver.
It’s also worth distinguishing between two situations. In a free practice session, the priority is to learn the geometry of the turn and get a feel for how the hull responds. In a race with multiple boats, protecting your space, following the rules, and avoiding dirty air can be more important than taking the shortest line.
How to Round a Windward Mark, Step by Step
Come prepared with a plan for the next leg
Before aiming for the mark, look to see where the course continues. In a barla-sota regatta, the start is usually a downwind leg or a broad reach. This calls for a gradual transition: you approach on a broad reach, with Mestra and Genoa sailed, and will come in, adjusting the sails as the apparent wind changes.
Plan your likely exit. If there’s a stronger wind on one side, more open space, or a favorable wave, that information should influence your approach. Don’t wait until you’ve passed the buoy to think about your next tack. Those who decide too late tend to make a turn that’s too tight and end up stuck.
Avoid reaching the layline too early
A layline is the imaginary line that leads to the buoy at the Heading toward close-hauled, without having to make another move. Finding it is helpful. However, latching onto it too early can be a trap.
If you sail too long along the layline, you lose options. If a gust lifts the boat, if the wind shifts, or if an opponent takes your wind, there’s little room left to react. In general, arriving slightly below the layline leaves room to accelerate and choose your entry point. The ideal point depends on wind strength, wave conditions, the boat’s close-hauled capability, and traffic.
In light winds, a cleaner, faster approach is usually worth its weight in gold. In strong winds with many boats, you might prefer a route that maintains control and gives you plenty of space, even if it seems a few meters longer.
In the final strokes, prioritize speed and space
When the buoy enters the decision zone, don't try to make up all the time at the helm. Large helm movements slow the hull down. Keep the boat balanced, the heel under control, and the sail trimmed for the close-hauled you're performing.
If the mark is to be on the port side, an approach on a starboard tack usually gives you a tactically strong position, because you approach with right of way over boats on a port tack. But that doesn’t give you free rein to close the gate any way you want. Within the mark zone, rules such as overlap and mark room matter, and the situation changes quickly as boats converge.
In a regatta, familiarize yourself with the rules of the class and the event before the start. In practice, don’t assume you’ll have room just because you arrived quickly. If in doubt, a slightly wider and safer approach may cost you less than a penalty, a collision, or a complete stop.
Take a smooth curve, not a sharp turn
An efficient turn isn't a sharp turn around the buoy. Think of it as a continuous arc. You enter with speed, start to turn before you're directly next to the mark, and draw a curve whose exit points toward the next leg.
As you begin to bear away, ease off the sails in a coordinated manner. The main sail usually needs to be eased first as the boat turns, and the genoa needs to be eased so it doesn’t become overly sheeted in. If you run aground with the sails still tight, they’ll hold the boat in place, increase the heel, and make the rudder heavy. If you ease them too early, you’ll lose lift before you can turn the change in course into acceleration.
The sensation you’re looking for is simple: the boat stops fighting the rudder and starts to move. Adjust, launch, and watch. If the bow is slow to respond, you may be entering too slowly or the hull may be heeling too much. If the boat skids out of the turn, you likely entered too quickly for such a tight turn, or you overused the rudder.
Drive off quickly, without looking back
After rounding the mark, the maneuver isn’t over yet. Stabilize the new course, trim the mainsail and genoa for the apparent wind angle, and aim for clean flow in the sails. On a downwind leg, the classic mistake is to keep the sails trimmed as if you were still tacking into the wind. The boat gets stuck, and your opponent, who eased off at the right moment, pulls ahead.
If you encounter a gust as you're tacking, don't just react by pulling on the tiller. First, reduce the pressure by adjusting the sheet and choose a course that keeps the hull balanced. On some boats, luffing slightly in the gust helps convert fclose-hauled into speed. On others, especially when there are high waves or a risk of losing control, it’s best to take a more conservative approach until the boat settles.
Mistakes That Make You Get Stuck at the Buoy
Getting above the layline is one of them. You have to bear away to reach the mark, which creates a bad turn and can cause you to get tangled up with those coming from below. The opposite can also be problematic: getting too low and being forced to make a slow final leg, right in the middle of traffic.
Another mistake is trying to make a perfect turn. Skimming just centimeters past the buoy may seem efficient, but it leaves you with less room to make the turn and increases the risk of hitting the marker or another boat. A slightly wider entry can result in a much faster exit.
Also, don't ignore the apparent wind. When shifting from close-hauled to a more open course, the direction and intensity felt by the sails change. The trim that kept the boat on course during the upwind leg doesn't automatically work on the downwind leg. The mainsail and genoa need room to breathe.
Finally, avoid letting the buoy become a braking point. If you slow down too much to resolve a last-minute tactical decision, everyone behind you will gain an opportunity. Make the decision ahead of time, communicate when you’re part of a crew, and keep the boat moving.
Practice until you can see the exit before you arrive
The best way to learn this maneuver is to repeat the same course under different conditions. Make one lap with a wider entry, another with a tighter one; test when to ease off the mainsheet, and notice which one allows the boat to regain speed first. Then, add gusts and opponents. A turn that works on its own may not work when someone takes your wind in the buoy zone.
In VelejAÍ, you can run this drill right in your browser and feel the consequences of each command: over-tacking, tacking too late, over-steering, or choosing a clean exit. Run a short race, try again, and compare the section after the mark. The stopwatch often reveals what the eye hasn’t yet noticed.
The next time the windward mark appears, don't just think about passing it. Choose your approach, carve the turn, and trim the sails so you can exit faster than you entered. That's where a good approach becomes a real advantage.
