Moudros Bay Anchorage Guide
Also known as: Moudhros, Ormos Moudros, Mudros
Moudros Bay is one of the great natural wonders of the Greek islands — a vast, almost completely enclosed sea bay that covers approximately 160 square kilometres and is accessible through a narrow entrance channel only a few hundred metres wide. The geography makes it one of the safest natural harbours in the Mediterranean, which is exactly why it was chosen as the base for the Allied Gallipoli campaign fleet in 1915. The French and British Expeditionary Force assembled here before the Dardanelles landings; at its peak, hundreds of warships and transports lay at anchor. The Commonwealth War Graves Commission cemetery at Moudros village (the largest WW1 cemetery in Greece) is an extraordinarily moving place — 877 graves of soldiers who died of wounds or disease before ever reaching Gallipoli. The Armistice of Mudros ending the Ottoman Empire's war was signed aboard HMS Agamemnon in this bay on 30 October 1918. Beyond the history, the bay is a birdwatcher's paradise — flamingos, herons, and numerous migratory species use the shallow areas. Bottom is thick mud throughout with exceptional holding.

Recommended Anchor Alarm Radius
80m for the vast bay in 4–8m on thick mud with excellent holding. The bay is so large that there is effectively unlimited swinging room — the 80m alarm is set conservatively to account for the soft mud allowing some drag before holding fully. Once firmly set, 65m is adequate. This is arguably the safest overnight anchorage in the Northern Aegean — the narrow entrance blocks all swell from outside.

Moudros is one of the largest naturally enclosed bays in the Mediterranean — approximately 160 square kilometres of virtually landlocked water, accessible through a narrow entrance channel. The entire bay is in 4–8m on thick mud with exceptional holding. In practice, this is an all-weather anchorage: the narrow entrance limits fetch and swell from every direction, and the internal bay size creates a calm surface even in strong external conditions. The WW1 Commonwealth War Graves Commission cemetery at Moudros village commemorates the Allied base used during the Gallipoli campaign (1915). A profound and moving historical site.
Setting Your Anchor
The bottom at Moudros Bay is primarily mud with reliable holding when properly set. Use the following approach:
- Approach slowly and check your depth sounder on the way in. At 4–8m, deploy at minimum 7:1 scope (56m chain at 8m depth).
- Drop into the wind or current and pay out chain steadily as the boat drifts back — do not allow chain to pile on the anchor.
- Set firmly in reverse. Apply moderate throttle astern for 30–60 seconds. The chain should tighten without the boat moving backwards.
- Take a GPS bearing. Note your position once set and compare to the scope calculator to confirm you have adequate chain for the depth.
Recommended anchor types for this bottom: Rocna, Mantus, CQR, Bruce. See our guide to anchor types by bottom for detailed comparisons.
Overnight Anchoring & Anchor Alarm
Overnight stays at Moudros Bay are excellent — 360-degree protection means minimal boat movement.
Set your GPS anchor alarm to 80m radius before going below for the night.80m for the vast bay in 4–8m on thick mud with excellent holding. The bay is so large that there is effectively unlimited swinging room — the 80m alarm is set conservatively to account for the soft mud allowing some drag before holding fully. Once firmly set, 65m is adequate. This is arguably the safest overnight anchorage in the Northern Aegean — the narrow entrance blocks all swell from outside.
Year-round anchorage. The bay is genuinely all-weather — the only anchorage in the North Aegean where you can anchor confidently in any wind direction and strength. Autumn and spring are particularly atmospheric. July–August sees almost no visiting yachts despite being peak season — extraordinary historical remoteness.
Navigation Hazards
- Entrance channel shoals — approach through the marked entrance channel carefully; depth over the bar is approximately 5–6m but shoals exist on both sides; proceed at slow speed with depth sounder active
- No yacht facilities — no fuel, no water, no chandlery; carry everything you need
- Fog possible in early morning in autumn — the large enclosed bay traps cold air; navigate with care
Rules & Regulations
- Permit: Not required beyond standard Greek DEKPA transit log
- Anchoring fee: Free
- Restrictions: DEKPA and TEPAI required. Entrance channel to the bay: follow the marked channel carefully; shoals exist on either side. No facilities in the bay beyond the village of Moudros — provision fully from Myrina.

Skipper's Tips
- The WW1 Commonwealth Cemetery at Moudros village is a deeply moving place and should not be missed — dinghy ashore and walk 10 minutes from the village quay
- This is one of the safest anchorages in the North Aegean in any weather — if a major storm is forecast, run for Moudros; once inside, you can anchor anywhere in complete safety
- Birdwatching: the shallow areas at the bay head attract flamingos, herons, and in spring/autumn, rare migratory species; bring binoculars
- The Armistice of Mudros (30 October 1918) ended WW1 in the Middle East — the bay where that history happened is now one of the quietest anchorages in Greece
A note on this guide: The data in this guide has been researched from multiple sailing sources and is provided in good faith. Anchorage conditions — including depth, holding, and local regulations — can change. Before visiting, always check current weather forecasts, NAVTEX and VHF weather bulletins, and consult your up-to-date charts. Use a GPS anchor alarm and never rely solely on a guide for navigational decisions.
Sleep peacefully at Moudros Bay
Safety Anchor Alarm monitors your GPS position continuously through the night and sounds a loud alarm the moment your boat drifts outside your set radius — essential in remote North Aegean anchorages where katabatic gusts can arrive without warning.
