San Diego Bay's waves hum with life. Dolphins gambol in the water, seals sun themselves, and sea birds swoop through the air. Humans enter the scene, joining the activity by exploring the waters on OEX Point Loma's stand-up paddleboards. Situated in Sun Harbor Marina, the shop stocks SUPs by brands such as Starboard, JP Australia, and Art in Surf, which its clients can rent along with kayaks on an hourly basis. The expert team also helms SUP lessons for novices, which cover topics from key strokes to safety tips, such as never to stand on the bottom side of your board.
