d/p it is real easy to put on and take off. I ran 8 1/4" bolts with nylock nuts thru the gunnals just to keep the platform from coming off the bolts aren't even tight i just snugged them up to keep them from backing out. because my boat wasn't square i had to weld the legs on using the boat as my template so it doesn't slide around from to back or side to side. Without the lights the platform weighs 42lbs. I would guess with the lights it's about 50ish those 2 hps lights in the front are pretty heavy but they work great.
