Mine was stiff when working it back and forth on the trailer. Once I got it on the water and under power, it was amazing!
Welcome to SCJB Good looking float It might just be the pic but it doesn't look like it fits the trailer very well. It almost looks like it's hanging off the rear and the front of the boat is almost to the coupler. If the trailer is that short, you'll probably want to find a better trailer in the near future.
