Renting a seaplane in the USA has become difficult due to insurance problem. There are only a very few places where a seaplane pilot can rent a seaplane and fly solo. I found a great solution at Tavares FL, America’s Seaplane City. www.tavares.org/899/Seaplane-Base-Marina. Here you can join a club for moderate costs, a seaplane insurance and 6 hours seaplane flying included. Rob and his crew are easygoing and helpful. www.jonesairandsea.com/seaplaneclub.
Unfortunately I was not able to fly it solo due to insurance coverage for this specific plane. Hopefully next time this will be solved and we can use it for trips. Below a flight with the developper of the amphibious Searey, Kerry.
