I am aware of most of the usual backing hints: back-up camera, side mirrors, steering by one hand at the bottom of the steering wheel, etc. I realize too that a small trailer has a small wheelbase which accentuates every small turn of the steering wheel. I have an original Alcort trailer which i bought in the 70's with two Sunfish. Of course over the years I have upgraded the trailer - new axel, wheels, tires, lights, repacking wheel bearings, etc. The axel can be moved forward or back but doing so throws off the center of gravity when boat is on trailer. I have a couple of problems which may or may not be unique. I'm blind in my right eye making it difficult to see over my right shoulder and the launch ramp I use has a fairly sharp slope. Not a problem when backing the rigged Sunfish, but when retrieving the 'fish from the water I cannot see the back of the trailer. I've tried the tennis ball on a magnetized expanding rod but to do much good I have to wade into the water to remove it before hauling on the boat. Very honestly i usually stop 2 or 3 times when backing and reposition the trailer by hand. I look like a fool when the guy next to me zips right in and out. So - any suggestions? Using another launch is not an option.
