If you stand it on end, can you add boards for shelves on the side of the seat? That way you could put pretty pots on it and use plants that grow longer.
We propped an old wooden boat sideways up against the side of the barn by the pool and added old patio seat and used it as a chill spot. Another idea would be to cut out one front side add cushion and hang it as a swing.
thank you.....like to try your idea!
A friend of ours turned her boat (similar) into a strawberry patch. She leaned it on it's side, so she could easily reach all of the strawberries and the runners would go down into the bed, but not tilted enough for the soil to errode. Looks & works great.
you could turn it into a fish pond (after sealing it to stop leakages) and then plant around it.
If you have small children, would make a great sandpit.
