I am 6'6" (about 198 cm) and 250 lbs (about 110kg). I swear I get pushed faster in current than other divers, who are of course usually smaller people. I frequently find myself being pushed ahead of the group and the DM for example, even when I am at the same distance from the reef and the same height in the water column.
Does anyone else agree?
Why would this be so?
From a theoretical perspective, it seems to me that if water is moving at X speed, unless we swim against it, we are all going to go at X speed once we are accelerated to that speed. However I do feel as if I get pushed faster than my fellow divers.
If I think about acceleration to get to X speed, then yes I have a greater surface area in contact with the water (surface area is proportional to the square of length), but I have a far larger mass to be pushed (mass is proportional to the cube of length) therefore I should accelerate more slowly.
I can't get this to make sense but it is my observation.
