I am similar to George C and Ocean Song. I have a boat in charter.

While briefing and getting you off/on the dock is part of the job, all appreciate a tip. Don't feel compelled to tip(I would say most do not think about it) but especially if someone goes above and beyond (which I think a tip is really intended).

I keep pockets filled with 10's and 20's, and distribute as I feel the urge, at the base, chase calls, and fuel docks, etc.

Sometimes, when service is sub-par, I don't reach into my pocket.
