yes i know i should know this but 

what do you consider to be  light, moderate, or strong current in relation to dive sites.  if it works  for you, would you give examples for world wide 'known' dive sites at their 'fastest', as illustrations

much thanks
jeff

Hi Jeff,

IMHO, many divers way overestimate the strength of the currents they’re in. It doesn’t take that many knots for things to get gnarly. Light current (to 1 knot); medium current (1 to 2 knots); strong current (2 to 3 knots); very strong current (3 knots); and too strong current (>3 knots). At 2-3 knots, the average diver cannot swim against it or even effectively stop in it. At 3 you get a ripping ride which at best you can only control. Above 3 knots you’re getting into a potentially dangerous situation.

Wickedest currents I've experienced were doing advanced diving off Tobago. Heart Attack Alley & The Washing Machine would tear your mask & fins off if you weren't careful. British Columbia tides and currents can be hair-raising as well.

Regards,
