It's the 21st-century way of learning to sail. You'll fully grasp the concepts here using e-learning technology, then we encourage you to get out on the water with one of our professional affiliated sailing schools and practice with a proper understanding. You'll then save time with the sailing instructor on these basics and be able to concentrate on the more advanced sailing techniques.

Using the interactive controls and animations, you'll be blown away (sorry for the pun) by your new understanding of this sail trim material and you'll no longer get frustrated when trying to explain the concept to others. If a picture is worth 1000 words then an interactive animation is worth infinity.

And finally, if you skipper your own sailboat, you're probably pretty versed with the material here and ready for the most advanced NauticEd sailing school courses. But we suggest, at the very least, sending your crew here to take this FREE Sailing Course. Then next time you go sailing, watch them make your sailboat go a knot or two faster. There is no other sailing course in the world that explains sail trim using such hi-tech e-learning methods.

So grab a cappuccino sit back and watch sail trim unfold in front of your eyes. Then, once you've figured out that we're the best at explaining this stuff you might try some of our other sailing courses and start to build your globally recognized sailing resume and certifications.

1.2 True Wind Vs Apparent Wind

We've created an interactive animation here so that you'll instantly "get" what everyone tries to explain laboriously on a blackboard without much success.

Click and drag on the slider bar. As the car speeds up, the wind increases in velocity and the direction of origin feels like it moves forward. That's apparent wind - it's what your hand feels out of the window and on a boat it's what the sails feel. If you stop the car, the apparent wind goes back to be the same as the true wind. The true wind stays the same regardless of your speed. That's it! Now you understand true versus apparent wind.
