Yes, three decades and a few thousand nautical miles.
I consider that a yacht is two halves of a glider on its side:
The mainsail being half a mainplane.
The jib being half the leading-edge droop in airflow with a large angle of attack.
The fin-keel being half a tailplane.
The rudder being an elevator.
Eg. Fabricate two identical yachts from very light materials, glue two together, throw very hard and it should fly. Briefly.
The navigation and communication principles and TCAS systems are also similar.
Traffic separation options in the vertical plane are, however, somewhat more limited than with aviating........
