I make one if you need to retrofit!!!
Wiring and lighting on a dock structure above a lake is a totally different application then pool and spa installations. GFCI breakers on the primary circuits, all SJOW 12/3 wire, fully grounded circuits throughout is the safe way to go. If installing into a new structure, you have the opportunity to run all your wire in conduit which is extra nice.
Have a safe day.
