...and there is a prohibition on the use of any powered vessel on LB-G.
Some electric vessels, some outboard-motored rowing school support vessels and a couple of tourist ferries have exemptions, but you ain't gonna see any "speed boat" out there on a normal day.
Setting all that aside... walk me through why all the little tackers on their becalmed or otherwise sailboats are obliged to make way for a seaplane.
