How do you build a flotation pod for a boat?
You must add these flotation pods to the outside of the boat. Contrary to popular opinion adding “flotation” at the transom inside the boat will not lift the stern. Any flotation added at the stern, unless it is added to the outside of the boat, will only add extra weight and make the stern ride even lower in the water.
