There are easy to apply waxes and hard to apply waxes. I've had good results with Collinite products.

These products do not require buffing, good results can be had with hand application. Use the 920 Cleaner and then either the 925 or 870 wax. It takes me about 3 hours a side on my 36 ft boat and I'm in my mid 60s.
Years ago in my youth I realized that the 2 most tiresome parts of waxing the hull was hefting the buffer around and climbing up and down the ladder and moving it every 6 feet. With Collinite the buffer is not needed and with a simple scaffold and 2 step ladders I can wax about 10-12 feet of hull without getting off the scaffold. (Until I inevitably drop the polishing cloths or the wax.) Clean a section of the hull and then wax it. Move the scaffold and repeat.
My scaffold consists of 2 Werner Fiberglass step ladders, one 7' and one 8' between the step ladders I have an 8' x 16" pick constructed of a 2x4 frame with a ½ inch plywood deck. As an alternative you could use a 2x12x10' plank, but that can get bouncy.
