Current can be very challenging in all kinds of surprising ways. You may, for instance, lose a fin while kicking against current, and because your fin is positively buoyant (who knew?), you have to scramble to retrieve it, only to find that the current is even stronger closer to the surface, and it has pulled you away from the group. You finally retrieve your fin, you manage to put it on, but in all the chaos you’ve lost control of your buoyancy, and you’re now rising to the surface fast. You fumble for your inflator hose but can’t find it, and now you’re at the surface, in a ripping current, alone. Happened to a fellow diver in a recent Red Sea liveaboard trip (northern route, at Brothers). The diver was picked up by a zodiac, but couldn’t rejoin her group for the dive.
Btw, on the very next dive, off the same boat, I lost a fin myself in strong current. I grabbed the fin quickly and vented air from my BCD, and dragged myself across the rocky bottom, hand over hand over, until I rejoined the group. Glad I was able to do that, because I had a pretty close encounter with a thresher shark as soon as I rejoined the group.
My point being, managing strong current is about more than just being fit and kicking hard. Buoyancy control, familiarity with gear, situational awareness, and experience with task overload is just as important.
A lost fin is not something I thought about, and a scary thing in fast current. With fins, I am strong and fast, but without them, I am helpless. I never tried swimming with 1 fin, seems a good skill to learn. My fins are neutrally buoyant.
I am not saying buoyancy control, familiarity with gear, situational awareness, and experience with task overload are less important. Just that I know what to expect. Current is posted a lot on this and similar threads, and I've never been in a situation that felt 'challenging'.
