The best way to attach a fender is put one on each pilling that your boat is tied up too.
Take your fender and tie the bitter end to the opposite end of the fender. Simple loop it over the dock post and slip it down. There isn't any movement nor do you have to make adjustments to make sure the fender is protecting your boat from posts. When leaving slip it up and off the post.

Drives me crazy when I see nice beautiful boats with fenders and bumpers hanging off boats as they flip and splash as the captain has not a clue that the fenders are still hanging overboard. But I guess it is ok. That way you can tell they are new to boating.
