Query: Suitable as a toy or a float for diving equipment

Here's the problem with these inflateable canoe's kayak's: They don't have a keel. I.e. they sit so high out of the water that they don't track when you paddle them. This is an issue when you want to go any distance or when the wind comes up. On the other hand, if you have a quiet lake and want to anchor a float for the kids to swim out to, climb in and out of, play king-of-the-float games, this will do. Or if you are a diver and want to anchor a float to hold your stuff after you bring it back up, this boat will do. But otherwise its an expensive toy, not a boat.Advantage over a regular canoe, difficult to tip over. Even when full of water, it will float high.Disadvantage, you can't go anywhere. It's no better than an inner tube on a river. If the wind comes up, you will be downwind quickly. Frustrating to paddle.
