Kev, there is no real spearfishing charters, it was advertised and it was disposed of.
In the sanjuans it was Island diving that last did some and put on there site.
Bandito charters has started a charter on the olympic pennisula, it is said to be the island diver boat they purchased. You can call rick and see if spearfihing divers might do a run sometime. The season is longer and earlier.
You can also just ask each charter if they have one go out that they just keep quite.
There are several divers that go on there own. I see more divers in front of my house during ling season then I do all year, And I am talking 3 boats during week and up to 10 on the sat & sun.
When are you coming up, maybe I can help ya better, or are you just making trip to hunt ling and cabezon.
Happy Diving
