Double Reactionary

Following Hawaii 5-0 there is a pool and then a stretch of about 1/3 mile of more or less continuous class 2. At the end of the class 2, the river narrows, boulders appear in the middle of the river and the gradient picks up - you are at Double Reactionary. There are eddies on river left; a 10 boat eddy follwed by a 4-5 boat eddy. From the lower eddy you can see some of the rapid, including the crux move. At two turbines, the entire right half of the river is too low to run. At 3 turbines (or above 1600 cfs) some creeky lines open on the top right. Most boaters will find the creeky lines easier than the meaty lines on the left.

From the lower eddy, you can just see the hole (about 25 ft off the left bank). You can start by clipping the left side of the hole. Depending on how much of the hole you bite off and your boat angle one of several opportunities will happen. If you are angled a little right and bite off a good bit you will be steered into an eddy on the right. From this eddy you can go to the "creek line" on the right side of the river (for most folks this is the easiest options). You could also peel off back into the meat.

If you are relatively straight and took only a small bite of the edge of the hole, you will be looking at a flat horizon line (not very high) as you approach it you can see the left boundary of the desirable line which is a curly tubular wave (like a surfer in a pipeline). The sweet spot is 6-8 ft to the right of the tubular wave. Take a boof stroke as you go over the edge. Once you land you can catch an eddy on your right. the creek like brings you into the other side of the same eddy. The remainder of the rapid is easier and an easy read. 

Rafts usually punch the top hole and navigate to the right of the large rock called Tombstone, which is undoubtedly the biggest wrap threat on this stretch. Especially early season, it's common to see rafts perched on this rock, but there's usually plenty of room to navigate around it. When the dam isn't releasing, rafts should run left of Tombstone.

About halfway in between Double Reactionary and Accelerator is a wave called Superglue that is one of the best raft surf waves I have ever seen. Easy to catch the eddy on river right side to work into the glassy wave that spans about half the river. At very high flows, these three features combine to form a rapid often affectionately referred to as "Double Super Accelerator".
