Are structures built to protect boats from large breaking waves?

Yes, structures such as breakwaters, jetties, and docks are built to protect boats from large breaking waves. Breakwaters are typically constructed offshore to absorb and deflect wave energy, creating a calmer area for vessels. Jetties extend into the water to stabilize navigation channels and protect harbors from sediment buildup and wave action. These structures are essential for ensuring the safety of boats and the efficiency of maritime operations.
