How well do you need to be able to swim?

Yeah, wording wasn't great. Though being confident and comfortable in the water, especially deep water, generally goes hand in hand with being able to swim.

From experience deep water is creepy, it was a cat that i went swimming off and even though it had no sails up and there was no wind it took real effort to reach the bows swiming up between the hulls. and i reckon it took about 5 seconds for the boat to move past (about 40ft) once you got 30 foot behind things started to look very small. try that on a ship thats moving at 20kns and i think you may as well put your head between your legs and kiss your A$$ goodbye
