We got a call today from DNR and they said everything was in tact but couldn't figure out the prop pitch because they were toasted!
We think they were trying to calculate WOT based on Hp and pitch.
All we can say is it was 'haulin' ASSS' to get up that hill.

They were stock 30 bravo's guaranteed. I can tell buy the way the boat laid on the side of the hill. If they were 32's the boat would of been 72 foot up the mountain and not 70!

First off the report said 71 feet, not 70....And that is NOT a 45 degree slope.
A 32 pitch with a forward uphill velocity based on the approximate 34 degree angle of the slope that I can calculate and at a constant 5150 rpms with a 17 percent slip should have put him at 18.655 meters or 61.204068241469386 feet!
Now you can see from the re-creation that the 71 feet is an obvious exaggeration. But it's hard to tell from the report if the measurement is taken from the bow or transom.
Also, if they used that little wheel like at crash sites it IS an uneven terrain so that would bump the number up some as well.
I really hope this clarifies a few issues.
Now wear your darned lanyards, OK?
Boat safe and enjoy the weekend!
