I agree about the effort not being worth the payoff. The hike with equipment, even using the trolley to go down to the beach, is too much work. There are many better shore dives on the island. The surface swim out into the bay is a bit of a pain. The best approach is to time your efforts with the surf. Only kick as the water pulls you out. Pay close attention to rock ledges. You may see some interesting things. My buddy, using the handle of his knife, played a gentle tug-of-war with an octopus. The little guy looked like he enjoyed the game, but didn't really want to come out of his hiding space.
