ATSC Weather for Sailing, Flying & Snow Sports (113) – Sailing Module Practice Test

The type of breaking wave described in the question is indeed a spilling breaker, which forms over gentle slopes and is characterized by its long, slow breaks and the white water that spills over the crest. This phenomenon occurs when waves encounter a gradual shallowing of the seabed, which allows them to rise and break smoothly. The energy of the wave dissipates more gradually in this process, resulting in a less violent break where the crest of the wave gently spills over the rest of the wave rather than plummeting straight down. Spilling breakers are often seen in areas with a gentle gradient, making them suitable for beginner surfers and more manageable conditions for various water sports.
