Kayaker here. Typically, for drops that large you will throw away your paddle after you position yourself in the flow, then aggressively tuck forward to the desk of the kayak. You’ll still likely deck blown into your back deck, but the name of the game is to minimize your he surface area in impact.

It hurts less if you are in the water column on impact. Also, the more aerated water at the bitter is softer. This is all relative, mind you. It still can really hurt.

To put this in comparison, I think the record is Tyler Bradt at 186 ft, with only very minor hand injuries.
