IAMA skipper of a fairly large commercial fishing boat that spends a good amount of time at sea. Our first aid kit is pretty good. It is not cheap, but contains what you need. They can make up different kits for different applications. I get it and the refills from Lafferty's Pharmacy in Ballard, in the Seattle area. As far as I can tell Lafferty's does not have a website, but here is a link to the brick & mortar: http://seattle.citysearch.com/profile/10783843/seattle_wa/lafferty_s_pharmacy.html
