The Chesapeake during the summer can be really hot and humid. For that climate I want loose-fitting and light colored clothes. I happen to wear cotton but I'm not dogmatic about it. Loose is what is important. Also a broad-brimmed hat and shoes ( prevents the top my feet from getting sunburned(done that -- never again) but mainly for protection from the various tracks and othwer hardware that populate the deck of my boat. Hitting those with bare toes really hurts.
Sufficient unto the day is the evil thereof
