Ran it once at 6000.
Made it from the put in to 6 mile in 45 minutes. Windy Hole will be HUGE, I was rowing an 18' loaded cargo boat and was convinced I was going to go end over on the second wave. I do not know why I didn't. Hit it square and going for all you're worth.
You'll have about 20 minutes of fast water, lots of stuff popping up at you that can get you into trouble; pay attention!
Cowpie kind of washes out, but still has bite.
OFER (Narrows) will try to suck you into the wall, but you have to get close to it to avoid the shit in the middle.
Then the last rapid, the wave train, is your reward; assuming you are still right side up. Long wave train.
If you aren't fully comfortable in class V fast water, with continuous rowing and lots of hazards, stay off this weekend. If you flip you have a long, long swim out.
If you are comfortable in class V fast water, with continuous rowing and lots of hazards, think twice about it and have a rescue plan.
