The Sailboat Rigging video shows how to properly attach your rudder to the tiller on a laser sailboat so that it never accidentally rises. 1mm of rising can result in significant speed and handling issues. This is very, very common with beginner/intermediate laser sailors and is a controllable variable we can easily dominate before even hopping in our boat. Most recreational sailors do not have their rudder properly secured and the line stretches resulting in excessive weather helm.
In the sailboat rigging video, we used the Marlow Excel Racing 3mm line to attach the rudder to the tiller.
With this setup in place, you can leave your rudder attached to the tiller under your boat cover - this also saves time for each sailing session.
