The Baymaster M1 Swim Under Cantilever umbrella is inspired by the wind-swept ocean and desert landscapes of the Baja Peninsula. The shorter mast allows for deployment directly over pools or patios with in-ground mounts within the base for added security and the parasol features an auto lift system on the back side of the cantilever allowing for easy opening from poolside.
