Did you know that the material used in boat hulls, called ferrocement, is a type of reinforced concrete and was once a popular choice for building durable but inexpensive boats? With layers of mesh and metal rods covered in cement, it creates a rugged hull with excellent longevity. Ironically, while intended to save on costs, ferrocement boats now have limited resale value due to labor-intensive repair needs. Have you encountered or heard about a ferrocement boat? Share your experiences or insights on this or other boat-building materials!
