I have the stern shade extension on my '22 Mojo. Takes about 3 minutes to put it up. Stores nicely in a bag, poles slide into the holes at the stern, clipe the corners of the shade on, velcro the other end to the tower and its done. I have driven wakeboarding speeds with it up with no issues. Just cant tow with it up because of the poles. Another 3 minutes to take it down and put it back in its bag. Totally worth it for me....I need shade.
