As a blond that goes from white to burnt, and has had skin cancer removed I do my best to not burn and to stay covered up or out of the sun. However this is not always realistic being on a boat out on the water. I use Coppertone Sport SPF30, and try and wear a hat to shade my face. I also wear a rash guard or something light and long sleeved. I work out on a boat and some days its like standing in an oven. The biggest thing is re-applying, and getting the spots that we forget about. We get arms and face etc, but the number of bad burns on the back of legs I have seen, ouchy.
