One of the guys there actually did land about a mile out to sea not to long ago, very nearly died from it.
I always thought id cut myself out too. but after that night im not so sure.
It only took me 15 seconds from the time i jumped of the edge until i was out and breathing again, it wasn't long but it was worse than i thought, I did not take a breath before i went under, i wanted to make it realistic/worst case scenario.
I fumbled getting my shoes threw the legs loop, a knife here might have helped, but you would still have to find and get your knife onto them after unbuckling and unzipping.
Another method used was unhooking, but the harness floats quite well. something i had not thought about, and it makes everything harder regardless of the method used.
last year they tried the knife and used string, but just as many "died"
The main thing is to get as prepared as you can before you hit the water, IF you get the chance.
Unbuckle, unzip, get your shoes off?, cut the hang straps and fall the last X feet to the water or fly in the A frame and climb right out the harness all together. depends how much time if any you have.
But we all agree, DONT land in the water
or if you must, head out past the breakers and land in the calmer water.
