Are there any concerns on using stainless steel inside the hull?

Bob,
Just like a lot of materials, all stainless steel is not the same "recipe". The more common stainless fasteners are "18-8" and "316". Around my area, Fleet Farm type stores are the cheapest source for stainless fasteners. Those fasteners will most likely be 18-8 as it is less expensive to produce than the 316 variety. McMaster Carr carries both choices and can be ordered online.
Some info;
18-8 stainless steel pan head screws have good chemical resistance and may be mildly magnetic. Length is measured from under the head.
Passivated stainless steel screws provide added protection against oxidation and corrosion.
Chrome-plated stainless steel screws have a decorative, mirror-like finish.
PTFE-coated stainless steel screws won?t stick or bind as you thread them into a hole.
Black-oxide stainless steel screws have a matte-black finish.
316 Stainless Steel
More corrosion resistant than 18-8 stainless steel screws, these button head screws have excellent resistance to chemicals and salt water. They are passivated for added protection against oxidation and corrosion. Screws may be mildly magnetic.
I have used the 18-8 with good success, HOWEVER, I am not in an area where I have to deal with saltwater exposure.
