My own solution to that was installing Boonedox landing gear. I went out memorial weekend where ramp was so busy with big boats. With all the gear setup at parking lot, I rolled the kayak, ask the boat next in line to let me use the ramp, continue roll the kayak after getting the thumbs up, and as soon as my kayak reached the water , jump in and paddle away. The point is I did not cause anyone to wait as I disappeared from the ramp the moment I hit the water. The same thing happened going back. There was a lot of boats waiting in line. About 10 meters away from the ramp, I dropped the wheels, Waive the next person in line to let me Cut in line, the moment I know it's knee deep, jump out the kayak right before I hit the concrete, reach out the front handle and roll the kayak back to my parking spot. Here's one video from YouTube to give you an idea.
