+## Wave Deflector / Wave Breaker Plate (压浪板)
17

18
+A **wave deflector** is a structure or plate used to **redirect, reduce, or break incoming waves**, protecting a surface, structure, or vessel from direct impact.
19
+
20
+- In **boats or ships**, it is usually installed at the bow or deck to **prevent water from splashing onto the deck**.
21
+- In **coastal or marine engineering**, similar structures help **reduce wave energy hitting seawalls, docks, or harbors**.
