Nice statement, a boat ramp certainly isn't emerging technology. I did have some offset drop axles on the trailer of my 83' V-20 which made it very low slung and easy to launch on those shallow ramps. The other side was not to forget to trim the motor all the way up before pulling out, you'd drag the lower unit off. I'm also familiar with the old seaplane ramps, they don't make good boat launches, far too shallow an angle. A contractor that misses this didn't do much research. We were able to build a nice concrete ramp in our old neighborhood and find the design information without any problem.
