A few comments form someone who has been doing this stuff for almost 30 years now.
Fining against a 2-3 knot current? A knot is 2,025 yards in an hour. Try fining at 1 knot for 20 minutes and then talk to me, no diver can fin at 2 to 3 knots for more then a few seconds. Fully rigged you might be able to keep up with a 1/4 knot current if you are in good shape; others have talked about the effect on gas consumption.
Are we not saying the same thing?
