316 stainless is a good choice for corrosive environments. Some
sailboat makers use it for rigging and good boatyards may stock it and
certainly will have swaging equipment and fittings if you can get the
cables premade. Otherwise, Nicropress fittings are a good choice and
you can probably rent the tools.

7x19 strand core is preferred for running over sheaves.
