no reason you cant use your bass tackle in the salt, unless you have lower tier equipment or Mg series reels.
I use my bass tackle (if that is what you call it)for everything from trout to kings and cobia. The curado 300 series reels can handle just about anything inshore. With the 200 series reels I have landed everything from trout to small tarpon along with many smacks and small kings.
I use 30lb braid with fluoro or steel leader, depending on what I am fishing for. Then just rinse the reels when finished.
If you are using lower tiered equipment, you may have issues with rust, weak drag and possibly things breaking depending on what you are catching but I always use a Curado when jetty fishing... Almost always...
