Boat dock wiring GFCI location

[Dkimbro]

i hung up my electrical license several years ago , I'm not familiar with boat docks at all. I have a new dock with a boat lift. distance from house to dock boat lift is 130'. boat lift has two motors that I would like to leave at 110VAC. total amp dwg is 24 amps with a ACII controller which needs a single 30 amp ckt. I also want a receptible and light at boat lift. we may want to add another boat lift later on second circuit. this is why i want to pull 220 out there even thought lifts will never be operated at same time. If I'm reading right i need to run #8 THWN . I'm running 4 wires ( black , red, white , and green) in sch 40 PVC from a disconnect at house to boat lift pole where controller is at. my question , confusion, is where to put my GFIC's. i would like to have a non fused disconnect at house for 220VAc 40 amp. put a sub panel at boat lift for 2 -30 amp GFIC's for boat lifts and 1 20 amp gfic for receptible and light.
is this within code and more important is this safe?
thanks,

I'm curious. When did you have a license?

i really don't know why that is relevant to my question but i passed my limited about 45 years ago. i have not done regular electrical work for 40 years when I hired on a medical company but kept up my license up till last year. just got tired of going to the classes...

When I do a boat dock, especially with boat lifts, I feed it with a 2 pole GFCI breaker (usually 100A) and install a NEMA 3R sub panel on a strut rack near the shore. The entire panel and every circuit that originates from it is GFCI protected. Do a voltage drop calc. after determining your total connected load for the proper wire size.

I'm sorry if I offended you. I suppose I was reading too much into the wording of your post.

110/220v is really 120/240v
GFIC is really GFCI
Receptible is really receptacle

I would put the GFCI protection in or near the subpanel at the dock. I would not put it on the house and then have 130+ feet of wire on the load side
