One thing Van never considered when designing the RVs
was using them as a seaplane! So, when he began
receiving phone calls from British Columbia, asking
questions about putting an RV-6 on floats, he had little
advice to offer.
Fortunately,
Eustace Bowhay, of Salmon Arm, BC, is a pilot with vast
experience in both land and water aircraft. He carefully
researched the matter and decided that the RV-6 had the
potential to be an excellent floatplane. After
consulting engineers, he designed a float installation
and submitted it to the Canadian authorities for
engineering approval. The Canadian Ministry of Transport
determined that the RV-6 was strong enough, without
modification, to handle the added stresses and loads
imposed by flying off water.
So Eustace and his partner Jim Rowe built a set of
floats that mounted to the stock RV-6 engine mount and
rear spar fittings. The whole installation was
successful, resulting in what Eustace thinks is the
fastest single piston engine floatplane in the world.
Cruise speeds, with the 180 hp Lycoming and constant
speed prop, were in the neighborhood of 150 statue miles
per hour. The water handling characteristics were
excellent and the airplane was easy to land and taxi on
land or water.
After
flying the airplane on both wheels and straight floats
for two years, Eustace and Jim decided they could have
the best of both worlds, and installed amphibious
floats. These worked just as well.
In 2005, Eustace, then over 80, decided that it was
time to step out of the cockpit. C-GHAY was converted
back to wheels and sold. Eustace died in 2006, leaving
behind a large group of friends in the RV world and the
legacy of one of the most interesting sidebars in the
continuing RV story.
