When you start sailing a new class of boat the best piece of advice is to keep it simple. opy the equipment, set-ups and techniques of the leading boats (perhaps the National Champion) and you give yourself an excellent starting point!

When making changes you need to make them one at a time, so you know exactly what the difference is. Record variations in as much detail as possible: you may nd some information, which at the time seemed insigni cant, useful to refer back to later. Try and keep the same principles when changing class, transferring the same equipment from boat to boat as much as possible, so that it is familiar to you. If you are making developments, try and do this in the off season, when there are not so many regattas, so you can give it your full attention and can see the project through to completion.
