I'll perfect the capsizing part before advancing to the yoga poses. After my two swims today I'm intending eight hours of Śavāsana practice tonight.
Yoga on stand up paddle boards is becoming popular. I think yoga on capsized Lasers could be the next big thing.
I have often capsized a Laser using yoga - I may not have consciously been intending to do yoga, but my twisted contortions just before the capsize surely looked a lot like some offbeat yoga pose.
There is more Laser Yoga at my post Laser Yoga?
