Natural Application to Waterproof a Ship’s Hull
When asked how wooden ships got waterproofed in ancient times, many will point to pitch or tar as one method, though this was certainly one possible answer. Unfortunately though, pitch/tar can pose its own unique set of challenges.
Tar is an oily sticky substance that was traditionally used as a sealant between planks of ship hulls; however, over time it would rot and weaken them over time. Furthermore, its pungent smell left staining marks wherever it touched; additionally it is extremely toxic if consumed internally.
Another method used on old wooden ships was using a mixture of rendered animal fat, bees wax, and whale oil mixed with linseed oil to protect from wood rot. Although somewhat more successful than using tar, this solution still failed to completely waterproof the vessel.
In the 1600’s, wooden ships were often re-decked using copper or brass which proved more cost-effective than tar. Unfortunately, this process was costly. A more affordable method is to apply Speedcoat-49 which provides a non-stick surface to deter fouling organisms from adhering to it – this can be applied using hand brushes or spray applicators and will last several seasons while being easily cleanable with a hose hose nozzle – marine suppliers offer it in various colors for purchase – spray on dock boards or boat deckings alike!
