Yeah, it does doesn't it? trouble is no one in this country carries stocks of "exotics" in the sizes that "boaties" find useful and everything's a trade-off. The most corrosion resistant doesn't have the highest tensile properties for instance.Best you can aim for if you require high strength and it's above the water line, if you need S/steel, is B8 class 2 (which is a 304 material heat treated and strain hardened to give good tensiles). Any good fastening supplier should be able to supply these, but there may be minimum order quantities.
I will look out some US contacts for you to try you may have luck there, they do tend to be more helpful with "nuisance" enquiries.
When we buy stuff like this it's generally special order, for larger sizes 60mm and above and it's a nightmare...
