On approaching the anchorage, be sure to honor the second red marker off (and fully past) the wood barricaded docks of East Hampton Point Marina before turning to starboard. This will avoid a shallow, but nearly invisible bar that extends along the west side of the channel. The town has free pump-out service can be summoned on VHF Channel 73 (call for pump-out boat).
