We 100% recommend the launcher.

My wife and I are avid kayakers, but the shoreline of our lake access is very muddy and rocky — not at all suitable for landing a kayak. When we first started kayaking we’d get into and out of the boats using a swim ladder, but that is difficult, particularly for my wife who has some mobility issues. Many years ago we purchased a kayak launcher from Get Kayakative. This proved to be a fantastic upgrade. Tied to our dock, the launcher makes it easy for us and our friends to get safely in and out of the kayaks. No getting wet, no worries about tipping over, or about damaging the kayaks on rocks. It’s a great device.
The launcher lives outdoors on our dock year round, and is in the water much of the summer. It has held up extremely well, despite being exposed to the weather. I have replaced the rollers once. Al was most supportive in getting me what I needed, and replacing them was simple — required no tools.
We 100% recommend the launcher. I think it is an absolute requirement if you routinely launch from a dock, and in many ways better than launching from shore, even if you have a gentle sandy beach.
