We signed up, downloaded and used the new UK/Halsey rules quiz program and we like it. Great graphics that show animated situations, with explanations and answers to the situations. You can pause and rewind which makes learning them much easier. Plus there is a rule book you can click on and find the (clickable) rules immediately. Really, if you are going to spend some time at your computer (and isn’t that all we do anyway?) this is the best way to learn the rules. Forget studying the overpriced US Sailing rule book (32 bucks for non members???). Spend 20 bucks more, get this program and do it right!
