Hey I know a seawind owner......
The plane is one of the best planes you will ever fly with your pants on or off. I have had mine up to 210 knots with a quartering headwind confirmed by ATC. Empty weight varies between 2400 and 2700lbs depending on the builder. Usefull could bring gross up to 4000, usually around 3600. I hold 112 gallons which will get me from NY to Fla....non stop.
The plane is only as good as the pilot!!
It is not easy to fly untill you get use to it. As in any plane, you have to keep in front of it as you keep in mind it is reversed from all other planes with respect to the engine location.
There are currently a few for sale on the website and the forum......
