Interactive sailing models
See what makes a sailboat move and stay put.
A small collection of interactive sailboat simulations. Change the conditions and watch wind, underwater forces, trim, speed, and ground tackle respond.
Sailing forces
Set true wind direction and strength, then explore apparent wind, automatic trim, polar speed, and the forces acting on the sailboat.
Open force visualizer →Anchor chain
Adjust water depth, chain length, and wind strength to see scope, catenary, seabed contact, and the boat’s movement at anchor.
