Wearing your flamesuit is not needed Lee.

1) you are experienced in beachcat distance races
2) you are familiar with the body of water being traversed (as evidenced by your mileage estimate and your ability to recognize the radio tower)
3) you were prepared for the conditions with the drysuit, safety equipment and blankets.

Anyone trying to flame you will need to come from a position of ignorance, and for that - you need not defend yourself.
