For shooting carp you will need to check out and get the sponsons(spelling?) from Spring Creek. for paddling open water set them above the water so they don't hang up on waves, but set them as deep as you can push them evenly and out as far the bar will go when shooting carp for optimum steadiness. I have a pair of lashing bars and we put two canoes together, they can still be paddled, but are more sea worthy than a pontoon boat. For fishing lakes with power boats, I put floats on one lashing bar with one canoe, then I do not have to worry about rollers coming off the power boats.
