Layline

Several sailing boats are trying to reach a buoy (red) located upwind. The wind comes from above. While the blue boat sails directly on the layline (black), the yellow boat gives away height. The green and orange boats turn onto the layline at different times, depending on their tactics.

The layline (English Lay line , even layline ) is the course on which a sailboat a wind-On-course sailing and just one windward location ton can happen without first contact to have or to touch the bin.

In order to successfully pass a buoy located upwind, i.e. without touching it, every sailboat must ultimately sail on or slightly above the layline. Only the point in time at which the layline is turned can be influenced using different tactics. A sailboat that sails too close to the layline, i.e. not far enough to windward, risks that if the wind changes unexpectedly, another cross may have to be sailed so that the buoy can be passed.

Regatta sailing

The layline often plays an important role, especially in regatta sailing . Not only the wind conditions are observed, but also the rules of evasion between watercraft . So, depending on which bow you are sailing on, it can make sense to sail on the layline at an earlier or later point in time, because you have to stay on course and the opponent has to evade.
