In the video above is my pontoon during a fast moving thunderstorm. This was the first true test of the system.
Previously I had a 50lb dumbell tied to anchor chain and rope. The weight would hold the boat just fine but in a storm or heavy wave situation the boat would drag the anchor slightly. I have had sand anchors, drift anchors, mushroom anchors d homemade anchors. This is byfar the best anchor I have had.
At this campsite the water is about 12"deep when you step off land and drops significantly as you go out with a mix of rocks, some sand but mostly fine silt. This area is on a point and the land is erosion protected by rocks and wrapped fencing so you have to make sure the anchor hold you off about 2' or your boat will be destroyed by waves pushing it I to the rocks.
You can see in the video that this anchor held strong. I would give 6 stars if it was an option. Folds up for easy storage and is very easy to set up and set the anchor point. It really doesn't matter how you throw off the boat because it will correct itself and dig in quickly. Removing the anchor is easy as well.
If you have a pontoon or any kind of boat that's heavy and needs a better anchor system do yourself a favor and buy this system. You will not regret it.
