Hi, relatively new to all manner of electric vehicles, but I’ve been reading a lot on this stuff, and been planning on making my own motorized surfboard.
I’m now trying to design the board and plan out the build process, while still staying in a student budget, and I started to wonder how pretty much all of the DIY motorised surfboards online use water jets with impellers, while practically every Efoil design uses a slower rotating propeller attached to the mast. Is it a question of useability? Do waterjets not work well underwater? Why dont surfboards use larger propellers?
I’d like to know more about the reasoning for choosing either one as the method of propulsion on a surfboard or an Efoil. I was going to buy a cheap used surfboard online and buy a beefy waterproof motor and propeller to propel the board, but decided to ask you guys first. My goal is to go very fast on a cheap, ugly board.
