I am thinking along the lines of Potomacbassin’. We are on a shallow lake. It is extremely shallow the first 200-220’ out from our shoreline. Water level drops significantly through the season. I sold our original lift and added Sea Legs 2 years ago as a result. It is excellent in solving any issues with raising the boat out of the water regardless of water depth, but can be used anywhere that is 4-5’ or less water depth - very handy. You can having it sitting on solid ground and just raise it up too.
As mentioned above, it’s an expensive solution though ($4-6k dual toon, $8-9k tritoon). On my lake it can also get very windy, wavy and ROUGH. Thus, not having a boat bang into the dock but also flexible with shallow water level, were combined concerns for us. This made the Sea Legs worthwhile for our situation.
I have had concerns a couple of times with my boat bottoming out towards the end of the season with a very low water level. The last 8 weeks of last boating season I had to walk my boat out to deeper water with 1-2 people standing on the bow to raise the stern slightly. Otherwise, It was bottomed out in the back.
