Stay away

Absolutely pointless. The setting adjustments are non existent. I thought I could learn the effects of one trim over another on the overall boat... just pointless application. Save your money!

Nothing Like It

In the sport of sailing, there’s no other application like this. The subtle differences on what you’re learning in sail trim with this app is what makes it so valuable. It’s not necessarily for the beginner, but you can take all the tools to your own boat and take it advantage of what you can learn with the simulator. I highly recommend it!

Great sail trim simulator

This is an outstanding tool for playing with the different sail controls and how they can affect performance. I wish they would add an outhaul control and eventually a reaching and running simulator as well. Regardless, this is a great training tool for you and your crew and it will only get better and more accurate over time.
