You have to remember, boating is a very small part of the R/C hobby. For every boater, there are at least a couple dozen or so aircraft fliers, probably 40+ drone fliers and a couple hundred car/buggy drivers. Personally, I build and race scale hydroplanes. You would think that in the Pacific Northwest, home to most of the teams over the last several decades, it would be a thriving community. Truth be told, it isn't. Last race I went to had around 40 boats and 20-25 drivers.
