Re: Expectation of Crew's Own Equipment
Somewhat redundant as others have covered many of these:
I keep extra tethers aboard for crew, but if I crew on another boat I like to bring my own.
Do you have "at least" a whistle and a light/strobe for your PFD.
A good knife and a multi -tool. Should be personal equip.
A headlamp or small flashlight, with a red lens is useful for finding things in the night.
If you've ever been seasick or think it might be a possibility, think about bringing meds. I carry a little bottle of motioneaze it seems to work for people even after they begin to feel bad. I think most of the other meds need to be taken beforehand.
