I worked for Excalibur Leisure Skills Boat in the early 90's.This project is different it provides insertion and retrive of handicap persons to & from boat on shore before launching your boat.Two different ways, via a seat or actual lift of the wheel chair for less mobil persons.Much safer on land then over water and designed for public self use.Also no time holding up launch ramp while loading or unloading handicap person.
