The Offshore/OPC jacket reduced my injuries as well.
Lost 1/2 a midsection and lower off of a 2.4 EFI on a 19 Laser at about 70 -75 mph The boat hooked real bad but rather than throwing me out, it threw me under the passenger side of the dash.
Tripped and stuffed the Bullet one time but rather going under the deck I went through it.
That jacket saved me in many ways.... I just never needed it for flotation.....
