Port Owen Marina Authority (POMA) manages the berthing facilities and waterways of Port Owen Marina, a sheltered estuarine marina on the Berg River. The marina provides mooring for recreational vessels and cruising yachts in a calm residential environment with river and ocean access. Berths are allocated through application and include short- and long-term options. Water and shore power are available at jetties, and a slipway operates under permit. The marina is community-managed and maintains infrastructure, waterway regulation and safety oversight.
