I would like to add to the above
I capsized in 30kn of wind with a green crew.
Upon righting a TheMightyHobie18, I MISSED grabing the dolpin striker with the
second hand. Therefore I was yanked out of the water by one hand.
Once the pain in my arm reached a high level, I figured my body
was trying to tell me something, let go, and fell on the new low hull.
This resulted in almost pulling my bisep off the bone, $7000 & 3 mo rehab.
(right biceptual tendon)
Yes, the hand/wrist muscles combined will overwhelm the bicep.

So, NEVER grab the dophin striker with one hand.
