About 35 South Marina
35 South Marina is the newest piece of the North Haven Boat Harbour, Adelaide's densest concentration of recreational berthing, and it pitches itself accordingly: modern floating berths, deep water, wide fairways and none of the club membership obligations that come with the neighbouring yacht clubs. The marina occupies 23 Alexa Road on the harbour's southern side, takes its name from Adelaide's approximate latitude, and grew in 2022 when its owners - already the largest berth holders in the precinct - acquired an adjacent slice of the harbour and added fifteen new berths. Berths run from around twelve to twenty metres, sized for monohulls and, unusually for an Adelaide marina, explicitly welcoming multihulls, whose beam defeats many older pens. The harbour setting does much of the work. North Haven's enclosed basin is dead-flat in any weather, completely protected from wind and swell behind breakwaters, yet the entrance channel puts a boat into Gulf St Vincent within minutes of slipping lines. The marina is unattended after office hours and relies on electronic access and CCTV rather than a marina office culture, which suits its typical customer: an owner who wants a secure, serviced berth, easy parking and a quick getaway rather than a social club. Thirty minutes by road from the Adelaide CBD, with Port Adelaide, the cruise ship terminal and the TechPort naval precinct as neighbours, it functions as the metropolitan coast's newest base for private motor cruisers and sailing cats. The name nods to the latitude that runs through the harbour, and the branding is accurate: this is a facility built by berth owners for berth owners, with expansion funded by demand rather than speculation.
Marina facilities
Berthing is the core product, offered for vessels up to twenty metres in deep-water pens with wide fairways that allow multihulls to manoeuvre without the pole-dancing required in older marinas. Every berth carries fresh water and power, with three-phase available for larger motor yachts, and the pontoons are reached through electronic security gates under CCTV coverage. Secure parking sits close to the berths, and marina trolleys are provided for the run from car to cockpit. Onshore, the marina has invested in comfort rather than boatyard hardware: a recently built amenities block with showers, bathroom ensuites and laundry, a customer lounge, and a barbecue area with a herb garden for berth holders' use. A small on-site chandlery covers consumables and basic spares, and directory listings also record a sewage pump-out and fuel among the marina's services. There is no travel lift or hardstand of its own; haul-out work goes to the DockYard precinct at Largs North or the slipping facilities at the CYCSA and the Royal South Australian Yacht Squadron, all within a short steam inside or outside the river. Booking is deliberately simple: there are no membership fees, berthing is quoted directly by the marina, and discounts apply for quarterly or annual payment. The office at 23 Alexa Road answers on 0447 221 841, open weekdays nine to five and closed weekends, so casual visitors should arrange arrival in advance rather than expecting a staffed dock on a Saturday. Berths are offered for sale and lease as well as rent, reflecting the marina's role as the precinct's largest private berth owner.
Local sailing knowledge
The North Haven Boat Harbour is entered from Gulf St Vincent through a dredged, beaconed channel between breakwaters; depths are reliable for keelboats, but the entrance is exposed to westerly swell and deserves respect in a fresh sea breeze, when breaking water can stand up across the leads. Once inside, the basin is landlocked calm, and 35 South's pens sit minutes from the entrance - a genuine selling point, since the alternative Adelaide option, the Port River marinas, adds a half-hour river transit each way. The harbour precinct has matured into a proper boating suburb. The CYCSA clubhouse with its bistro and restaurant overlooks the water a short walk away, and the Sailmaster Tavern and waterfront eateries around the basin cover dining without a car. Fuel is available within the precinct at the club fuel berths. By road, Semaphore's main street and beach are five minutes south and Port Adelaide ten minutes, with supermarkets at both. Cruising options divide neatly: inside the gulf, the metropolitan coast from Outer Harbor down to Glenelg offers sheltered day sailing with anchoring off the beaches in settled easterlies; across the gulf, the run to Kangaroo Island's north-coast anchorages - Kingscote, Bay of Shoals, American River - is roughly fifty nautical miles and the standard long weekend. The resident Port River dolphins frequently escort boats through the entrance, and snapper and whiting grounds in the gulf keep the fishing fraternity in the marina year-round. Trailerboat owners note that the harbour's public ramps can queue on summer mornings, one more reason berth holders here value simply turning the key and idling out.
