I realize we are straying off subject here and I know nothing about rules or regs regarding a "Guides License". Isn't the guides license that a Guide pays $180 for, good for only fishing on rivers? I think you need to be CG licensed and have a 6-pack Salmon license (hard to come by) to take people out (as a Charter) on the salt to fish for Salmon.
Again, I could be way off base here...

Anyway interesting subject, I'm always curious how other boat owners and their fishing buddies handle what could be an awkward situation. I usually supply the gear (unless they have their own or I have fished with before and they bring their own) and say pitch in a few $$$ for gas.
