Sorry, can't help on the CADDIS Navigator II. I had the North Fork Outdoors Navigator II. Same as Ducksterman. They are 9' long "V" tube/toon with oars and optional shelf for a motor.

Not the same boat at all.

I can say with past experience, I try to stay away from any TUBE that requires a cross brace. If it breaks or you forget it, you are out of luck totally.
