There is a lot going on in a float plane during take offs and landings.We are keeping tabs on wind, current,waves,traffic both on the water and in the air.That is a VERY busy time.I can't imagine someone having the time or willing to take the chance of death or serious injury to play around with a sailboat on the water. Why don't you sail over to where these aircraft are docked and start a conversation with the pilots? There is a good chance they are unaware of your concerns and if you guys can get on the same page, it will be much safer for everyone.I fly off of a river and the pucker factor when there are boats in the area is high.Power boats drivers are a big problem but pwc guys, well...I'm sure you can relate.
