I'm looking for some current feedback on overall design and quality of
parts. I'm partial to a flying boat vs. float plane.

Kits I've been researching to this point a

SeaWind 3000 - Not building kits anymore but there projects for sale
SeaStar - No new news letters since 2002?
SeaStorm Z4 - No completed planes in the US.

I'm looking for an aircraft that can realistically be operated in
sal****er that is a true 4-place amphibious aircraft.

Any insights would be greatly appreciated.
