Boat Outfitting — frequently asked

What material should marine hardware be made of?
For most exposed hardware, 316 stainless steel is the marine standard — it resists salt corrosion far better than 304 stainless or plated steel. Marine-grade aluminum, UV-stabilized nylon, and King StarBoard are also common for non-structural fittings.
How do I know a replacement seat or hatch will fit?
Measure the mounting pattern (bolt spacing), the cutout or base dimensions, and any post diameter or height on the part you’re replacing. Match those to the new part’s specs — outfitting parts follow common sizes but are not universal, so confirming dimensions avoids returns.
Do I need backing plates for deck hardware?
For anything that takes load — grab rails, cleats, ladder steps, seat pedestals — yes. A backing plate spreads the load across a larger area of the deck or transom so fasteners don’t pull through under stress.
