Hi. Just found this promotion for Mobiloil in a technical magazine in Sweden in 1955. This is nice showing that the unlimited hydroplanes were famous in Sweden even though we didn´t have unlimited in Sweden. Since I have been furtunate to meet Ron Jones Jr last year at the Hydroplane Museeum this is special to me.... Hope to be back soon...…

About four weeks ago I was able (with a few friends) to locate the first of a series of inboard hydroplanes built in Sweden. It was built in 1963/64 and based on a design by Ron Jones Sr. It was powered by a Volvo 4-cylinder engine souped up to about 135 hp. It was raced in the 1800cc class and was able to reach speeds around 70 knots. This boat was found in a barn where it has been sitting since 1967. Rear cowling, engine cowling and the engine is missing but otherwise it is in not too bad…

In early April I had the chance to visit the Hydroplane museum for the first time. I would like to thank everyone for the welcome and I must say I am impressed by the work and dedication of everyone. 

I am working with a boat museum here in Sweden but we have nothing like what you have. Being a boat racing fan it was like coming to heaven. There is nothing even close to unlimited hydroplanes here. I am restoring a small inboard hydroplane which origin is from one of Ron Jones…
