Heading north up Calm Channel after launching from Rendezvous Island.
When making the trip through Yuculta Rapids the currents are weaker at slack tide turning to ebb than at slack tide turning to flood so I timed my passage for the weaker slack tide to ebb. The current table to use for Yuculta Rapids is Gillard Pass. If you are going through at ebb, like I was, add 5 minutes to the figures for Gillard Pass to get the time when Yuculta turns to slack. If you are going through at slack turning to flood, add 25 minutes to the figures for Gillard Pass. For example, on June 23, the current table for Gillard Pass showed slack turning to ebb at 12:40pm. I added 5 minutes to that and knew that the current would be slack in Yuculta Rapids at 12:45pm. Now all I had to do was be there waiting to go through at 12:45pm.

I was glad to have company for this section of the trip as I had never experienced saltwater rapids before and did not know exactly what to expect. It was comforting to know that we had both figured out the time of slack tide to within minutes and that we would not be going through at the wrong time and get into trouble.

We had six miles to paddle to the tip of Stuart Island where the entrance to the rapids begins. Not wanting to be late for our rendezvous with Yuculta, we launched at 9:10am and had no difficulty making the six miles in two hours. We found a small bay with a dock at the tip of Stuart Island and pulled in to wait out the next hour and a half. At 12:30pm, we pulled out of the bay and slowly started making our way around the tip of the island and towards the infamous Yuculta Rapids that were about a half mile away.
This is what Yuculta Rapids looks like at slack tide.
After all the agony of anticipating this section of the trip, and all the horror stories we had heard about these treacherous waters, the surface turned out to be smooth and calm. We realized though that if we had not done our homework, and taken the timing of running this stretch seriously, the outcome could have been much different.
