From its position as the eye of a watersporting storm within walking distance of both the wave-laden Pacific Ocean and the placid Mission Bay, Mission Surf furnishes oceanic excursionists with a wide selection of one-person watercraft. The shop's board stable is stocked with both soft-topped and epoxy-coated long and short surfboards, as well as cushy paddleboards and steamrollered sharks. Thrill-seekers can leap atop a sleek surfboard and ride the tides that endlessly pound the coastline, zipping among whitecaps and floats of kelp. With a simple-to-operate paddleboard, easy riders can explore the coves and rippling waters of the secluded bay, or venture out into the oceanic surf for a more intense adventure. The chilling effects of brisk waters are staved off by the included wetsuit, which keeps boarders warm in the event of a wipeout or iceberg collision course.
