Last year at around 1.5' with 18' commercially loaded boats IIRC 3 went right with little trouble- maybe 1 of them got stuck for a moment- and the other two wend left with no trouble. Left was quite a big drop, though, and I could definitely see things going badly there.
To go right you need to be committed to going right well above the island/cobble bar, but not all the way along the bank. It's a waiting move where you float past 2 good sized marker rocks, then cut right. It's shallow, and tight, but not too fast. If you go right too soon you'll have a tougher time. I'll see if I can find some video of this line.
