The various DB retention systems work OK but can't be trusted...especially in the surf. Wave action and the pitching of the boat can cause your boards to fall down into the wells. My crew and I remove and stow the DB's under the tramp hiking straps when launching from or landing on the beach. Only when we are through the surf line and in deep enough water do we engage the DB's in the wells. It's not good for the wells or the boards to have one slip down accidently and grind the tips off. Keep 'em on the tramp until it's safe.
