Got to a new ramp today and found it to be very shallow (as in "not steep"). Could only get about 33% of my 18-foot bowrider wet before my vehicle's tailpipe was in the water. Had a hell of a time pushing, rocking, reversing, etc before I could launch the boat. Am I missing an obvious launching technique on a ramp like this? Is this the big advantage of rollers vs bunks (I've got bunks)? What's the best way to deal with a ramp like his?
