and this is what i have come up with for the rails of a thruster or even a fish.
nice thin rail that will cut through the water without catching, but with a middle section that has enough foam to keep it floating or making it super easy to paddle depending on how thick you get it.
getting best of both worlds or being able to rider a shorter thruster that doesn’t sink when you go to stand up.
i call it the IMR Rail.
let me know what you guys think.
