Are you talking about a propulsion fan or a keep you cool fan? A propulsion fan will require registration and numbers.

Registration requirements aside, graphite composite and the hub is CNC machined from aerospace grade aluminum alloy would be a premium choice & cost. Wood is likely your best option. Plenty of info online, this is a pretty decent site as well.

Look forward to your build, love seeing folks innovative ideas with this sport. Think I'm just tired, first saw this thread I was thinking hovercraft :lol: .

What are you using for an engine?

A little engineering talk here. The thrust line of the power can get high enough very easily to just roll the yak. In fishing you try to keep the rod close to the bow to prevent a side pull from causing you to turtle. The fan thrust can do the same thing, especially in a turn. Our SOT yaks are not designed to handle force thrust more than a few inches above the water line or from the sides. You might end up needing outriggers for the boat like the Adventure Island sailing rigs use. Good luck on your idea. It will be fun to follow, but I do not want to be the test pilot.

Not sure how large a Prop you are thinking of using, but have you considered using Brushless Electric motors? The very same ones you would use in RC Planes? you could mount 2 on the rear of your Yak, counter rotating and have some Lipo cells in a waterproof box with controller. you honestly could be up and running for less than $300. I would recommend outrunner motors vs inrunner motors. they are lighter and have more torque. just my .02. Looking fwd to the build

would a small fan motor be too big to put on a yak? They use them on flounder boats all the time.

I have a good size ocean yak so I don't think a small fan would be a problem just depends on the weight limit of your yak plus im building outrigers for it also so that helps to :dance:

If you mount the motor and prop on the front of the yak pointing at you then maybe you can get away with no registration. You could then pass it off as a air-cooler for the paddler when you are at top speed! :mrgreen: You can purchase large scale aircraft props from the hobby shop in two, three or four blade made from plastic or nylon and they would work great. Most that size fit on a 1/4" shaft and they do have pusher props available as well. Can't wait to see the pictures! :clap: :clap: :clap:
