Lombok map

Medana Bay is in the red circle in North Lombok close to the three Gili isles. Mount Rinjani rises to the east at 3,726m high. The sailing route from Java and Bali to Flores and other eastern islands follows this route north of Lombok. Lombok international airport (LOP) is 90 minutes away near Praya, Central Lombok. The Fast Boat terminal at Teluk Nare is just 15 minutes away.

Sea Chart



The approach from the east tracks through 08°20.067'S and 116°08.361'E in deep water to our transit waypoint at 08°20.432'S 116°07.685'E where it bears south into Medana Bay – locally called Teluk Dalem, meaning Deep Bay. If your approach is a little to the north of this track you may be surprised by the depths suddenly becoming shallower from over 20m to just 7m as you pass over some coral. Don't be alarmed – you do still have 7m of water in this shallow spot. 

The approach from the west tracks in north of Gili Air and Gili Trawangan to the same transit waypoint, keeping half of Gili Meno in your sights behind Gili Air. This is to ensure a wide berth of the coral fringe to Medana headland.

The mooring basin is at 08°21.833'S   116°07.750'E. The approach way-point is almost due north at 08°20.432'S and 116°07.685'E. Please refer to our Sea Chart and ‘google earth' map.
From the transit waypoint please observe and align your transit with the Leading Marks set behind our pontoons on the beach – two white squares with red outlines. These will bring you safely along a deep water channel 300m wide and 30m deep into the central mooring area 150m wide and 15m deep. At night time the rear upper marker has a white vertical strip light, and the lower forward light is a vertical blue strip.

Our Port (red) and Starboard (green) marker buoys are set at a minimum depth of 4m inside the protective coral reef. Sometimes they are damaged by impact from local fishing boats. It is best to follow the Leading Marks into the mooring basin, then choose your mooring, or come straight on to a booked berth.


The mooring buoys are the plain black floats with a smaller white ball float attached to the painter for ease of pick-up.

A love of the sea and its environs brought us together to fulfill a dream and build a marina on Lombok. Between us we have a range of skills, knowledge and networks wide enough to bring this project to fruition.
Our plan is to build a full service marina and develop the surrounding property. The facilities will meet international standards in terms of environmental protection and well trained staff to provide top quality service whilst holding our costs and prices to moderate levels.

Medana Bay was selected in 2006 as an ideal spot on Lombok since it meets the requirements for such a project from both the marine and landside development aspects. The bay is a natural safe harbour, protected from the prevailing major winds and waves. It is on the preferred sailing route to the eastern isles, yet within easy day sailing from the Gilis, and short trips to the Sekotong peninsula and surrounding islets. On the land side there is established infrastructure and we have built a hotel, meeting hall and café in a very tranquil coconut grove garden setting. Nearby there are also several 5* hotels and an 18 hole golf course at Kosaido Country Club.

PT Wisata Alam Samudera is the name of the corporate body and receives full support from the local authorities; the Bupati, the Harbour Master, the Customs Department, the Communications Department, Immigration Office and the Governor of NTB province.

Marine consultants from LAPI-ITB Bandung completed the initial engineering studies and the detailed bathymetric survey of the bay, required to initiate a marine license application. Mataram University assisted with the environmental surveys and assessments required for a number of presentations and reports by the company.

The Department of Sea Communications in Jakarta issued a license for the development of a private harbour and associated facilities to PT WAS in September 2009 and issued the construction license in January 2011, and the operating license for our first stage facility in Fenruary 2013.

Medana Bay Marina successfully hosted Sail Indonesia Bunaken in 2009 with over ninety yachts enjoying the facilities and has continued to do so annually including Sail Indonesia (Tomini) 2015 and Sail2Indonesia and the Blue Planet Odyssey in addition to an increasing number of independent private sailors and yachts.
The marina and resort is planned to develop in three stages. We have completed the first stage development of a 17 room hotel overlooking the gardens and bay, a 200 person meeting hall and separate covered buffet reception area, together with our beachside café, Sailfish, and more importantly a floating berth system rigidly attached to the concrete shore anchor block. This provides berthing for 10 vessels with metered pedestal electrical supply and metered fresh water. The company is now in the detailed planning stage for the longer term development of the marina together with a slipway, hardstand and basic maintenance facilities.


There are many marinas in Thailand, Malaysia & Singapore, but so far, only ourselves and Nongsa Point in Batam in a blue water, island setting in Indonesia.


  1. Many marinas in Thailand, Malaysia & Singapore. So far none in Indonesia in a blue water, island setting.

  2. Lombok is 8-9 degrees South – opposite weather pattern to Langkawi & Thailand. Our best weather: June to September. Monsoon weather in Phuket at that time.

  3. Identified and surveyed a site, completed early engineering.

  4. Deep water access, safe from major winds and waves.

  5. Acquired the rights to a 7 hectare site.

  6. Existing Oberoi Resort and Kosaido golf course adjacent.

  7. Indonesian companies for project development formed and permits for a recreational harbour (marina) granted.


  1. Safe, deep water access for water craft.

  2. Minimum exposure to prevailing winds.

  3. On preferred north coast sailing route to Flores.

  4. Proximity to Gili islands for day sailing activities.

  5. Natural harbour setting – minimal excavation required.

  6. Existing landside infrastructure – roads, water, electricity: require upgrading, not pioneering.

  7. Nearby high quality golf course and hotel.

  8. Within the designated tourist development area.

  9. Nearby educated workforce, ready for training.

Gili Air lies just 4 miles to the west and The Oberoi Resort, The Lombok Lodge and Medana Resort are all within walking distance. Tanjung town is 4km to the east.

tranquil lagoon

Wind Rose. Medana Bay is only open to winds and waves from the North and North East. It is totally protected  from the more frequent and stronger westerlies and southerlies.


Outer & Inner Harbour plan with breakwater – natural water depths of over 12m. Channel to inner harbour, with excavated depth of 5m – which provides 2.5m water at lowest low tide. This model was used for our development cost estimation.


An alternative plan for the inner lagoon – using a lock between the sea and the tranquil inner harbour.
