I personally hate PFD's, but think that fair enough let's all wear them.
But I would like to see a new class of PFD that is designed for racing that is not as bulky or hot.
There is no need for a jacket that you can survive a week in for racing, just a little help if you got clocked on the head or busted a shoulder or like so that you don't expire before a rescue boat gets to you.
For much longer paddles in open water with a spread out field, maybe a full version.
But if they are to had to enter the race, they achieve nothing if not worn. Either have them or not, no half ways.
I think a leash must at least be present but you be allowed your own judgment as to when to wear them.
P.S. Try using paragraphs, it makes for much easier reading.
Follow the path of the independent thinker. Expose your ideas to the dangers of controversy. Speak your mind and fear less the label of 'crackpot' than the stigma of conformity. And on issues that are important to you, stand up and be counted at any cost.--- Thomas J. Watson
