Koroni Anchorage Guide

Anchoring Zones

Koroni has 2 distinct anchoring zones, each with different depth, holding, and exposure characteristics.

Setting Your Anchor

The bottom at Koroni is primarily sand and weed with reliable holding when properly set.

1. Approach slowly and check your depth sounder on the way in. At 4–10m, deploy at minimum 7:1 scope (70m chain at 10m depth).
2. Drop into the wind or current and pay out chain steadily as the boat drifts back.
3. Set firmly in reverse. Apply moderate throttle astern for 30–60 seconds.
4. Take a GPS bearing. Note your position once set and compare to the scope calculator.

Recommended anchor types for this bottom: Rocna, Mantus, Spade, Delta.

Overnight Anchoring & Anchor Alarm

Overnight stays at Koroni are feasible but require monitoring. The anchorage is exposed to S and SW and W and NW winds.

Set your GPS anchor alarm to 85m radius before going below for the night. 85m for the main anchorage with sand/weed bottom and W/NW exposure. The afternoon NW sea breeze in the Messenian Gulf (F3–4) creates short chop from the W — ensure anchor is set before the afternoon thermal develops. In the inner harbour, 40m is sufficient. The wide W/NW exposure means Koroni is a daytime or settled-weather overnight anchorage; not a bolt-hole anchorage for strong W conditions.

May–September is the season. The Messenian Gulf is generally sheltered from the worst Ionian gales by the mountains to the west, but W swell can penetrate. The afternoon NW thermal is a reliable feature June–August. October sees declining conditions; the bay is not recommended for off-season use. September is outstanding — warm, clear, and uncrowded.

Navigation Hazards

• W/NW afternoon sea breeze (Messenian Gulf thermal) builds F3–4 from early afternoon, creating chop in the main anchorage; inner harbour offers more protection
• Sand/weed bottom: anchor may skate on weed; snorkel to confirm penetration into sand beneath; test holding under power before going ashore
• Harbour entrance bar: can shoal to <2m; sound carefully before entering the inner harbour, especially for deeper draft boats
• Open to SW and W: any S or W system makes the anchorage unsafe; depart for Kalamata or Pylos in westerly conditions
• Limited fuel: none available at Koroni — nearest at Kalamata (22nm) or Pylos (25nm)

Rules & Regulations

• Permit: Not required beyond standard Greek DEKPA transit log
• Anchoring fee: Free
• Restrictions: DEKPA and TEPAI required. Fishing harbour: fishing boats have priority; yachts stern-to by arrangement with the port authority. Check depths at the harbour entrance (bar may be <2m). Posidonia weed patches in anchorage — verify anchor on sand.

Skipper's Tips

1. One of the most beautiful anchorages in the Messenian Gulf — the castle and village combination is outstanding; do not miss the climb up to the Venetian fortress
2. Arrive before midday to avoid the afternoon NW thermal and secure the best position close to the headland for maximum shelter
3. The inner harbour offers better overnight shelter in NW thermal conditions; ask the harbour master about available space
4. Good lunch stop on the Methoni–Kalamata passage; the waterfront tavernas are excellent value and authentically local
