You can go ahead and use the old-style valves; at least until you run out of propane. As far as I know, you can NOT get non-OPV tanks refilled anywhere in the U.S. any more.
And if your tanks are old enough, you can't retrofit the OPV valves without getting the tanks re-certified first. You're probably better off just getting new tanks with OPV valves and being done with it. You can now get the translucent fiberglass tanks, which are great for the marine environment -- they won't rust, and you can actually see the propane level in them: http://www.defender.com/product.jsp?path=-1|406|301237|322407&id=1065959 They're not inexpensive; but what is on a boat?
