The seaplane rides is a great gift. We took this flight two years ago and it was great. He will work with you and arrange a pick up at your dock.
He flies out of Paugus bay and I did see him there this weekend.
Here is the website.

There is also a Waco biplane that flys out of the Guilford airport.

We have taken both tours and they were both memories we will never forget.
