Well... I've run my jet boat on the shallows between Sultan and the Wallace. It's not fun to go from 25mph to a dead stop. Left some nice dents in my hull. I have a Klamath which is a thin hulled boat, not in the same class as a Woolridge. The only advantage for me is I can manhandle it off the gravel. You'll have a harder time with your boat. Best advice, scout it out before you run through. After my grounding my heart is always in my throat. Makes it less fun for sure.
