If you are focused on veg, then you'll have to either forgo it, or arrange to leave your plants dockside. Herbs are generally small enough that you can bring the pots inside the cabin
spray becomes likely. But if you don't mind growing alternative stuff, there is plenty that can be grown that is salt tolerant and even favors some salt.
Cranberries, beach plum, beach rose (for the rose hips). Some edible leafy veg like some purslanes.
If you want veg you normally find in the produce section, then not so much, but if you research
wild edibles that live on shorelines and salt marshes, then you have some choices. Obviously New England

Well in the north except during the summer months.
You have 5 years to do your research
and you can learn quite a bit, and even get some stuff (like berry shrubs) established and growing before your shove off.
