Paul Elvstrom Explains the Racing Rules of Sailing: 2017-2020 Rules

we used it during a protest. we lost, but not because of this. we will have it with us, on board, from now on, along with our code b flag and zip ties, in case we have to protest again

Needs color so Kindle not so good, but excellent resource to understand racing rules. Most useful book I had read on the topic

Still works very well.

Just great. I love the explanations and the addenda.

Very good explanations in clear English. Good diagrams and specific references.
