Bute is an awesome spot for sure. Most importantly is pay attention to the outflow wind coming out of the inlet you will want to have a good point of land to hide behind. If you travel on the SE side of Stuart Is Henrietta point you won’t have to worry about any rapids. There is good anchorage at fawn bluff bay, across the inlet at Moh creek and in front of Orford river. Chinooks are done but should be some coho around Moh creek and clipper point to Orford river. Fish boundary is about 6km past Orford river. Prawning will be slow due commercial fishery but probable find enough for a meal or two you might find some crab in front Orford river.
Enjoy Bute.
