What affect does shallow water have on a vessel's stopping distance?
Official USCG Answer & Rule Citation
Correct Answer: Option B — The stopping distance is longer.
Shallow water increases the hydrodynamic resistance and the squat effect, which significantly extends the stopping distance of a vessel. The restricted flow of water around the hull and propeller reduces the efficiency of the engine and rudder, requiring earlier and more deliberate action to bring the vessel to rest.
