The Operational Context: Sailing the Sulcis

The waters of the Sulcis-Iglesiente region are among the most fascinating yet technically demanding in Sardinia. Porto Zafferano (Cala Zafferano) is located in the heart of the Capo Teulada Military Firing Range. Navigating this area requires rigorous knowledge of Coast Guard ordinances and local wind patterns.

This guide, drafted with the expertise of professional skippers, provides the essential coordinates for a safe and legal experience.

Safe Approach Routes

From Porto Malfatano (Approaching from the North-West)

  1. Maintain a heading of 200°–210° (S-SSW) for approximately 4 nautical miles.
  2. Identify Punta Zavorra as a visual waypoint to starboard.
  3. Enter the bay on a heading of 140° (SE), maintaining a minimum distance of 0.3 NM from the coastline.

From Tuerredda / Porto Tramatzu (Approaching from the East)

  1. Sail West (heading 270°–280°) for about 2.5 NM.
  2. Round the rocky point maintaining a wide safety margin (0.4 NM) to avoid submerged shoals that are not always visible in rough seas.

⚠️ RESTRICTED ZONE: DELTA PENINSULA

The Delta peninsula is permanently off-limits. It is a military exercise area that cannot be cleared due to the presence of unexploded ordnance. Transiting or anchoring in the zones marked by yellow buoys will result in the immediate seizure of the vessel and criminal penalties. Always monitor VHF Channel 16 and the Sant’Antioco Coast Guard ordinances.

Bathymetry and Seabeds

The basin of Porto Zafferano features a predominantly sandy, light-colored seabed, providing excellent holding ground for the anchor.

  • Center of the Bay: 3–6 meters depth. Clean sand, excellent holding.
  • North/South Fringes: 1.5–3 meters. Massive presence of Posidonia seagrass. Anchoring is strictly prohibited.
  • Entrance: 4–7 meters. Transit zone subject to weak currents.

Wind Patterns: Maestrale and Libeccio

Maestrale (NW)

This is the prevailing wind. Although the bay is partially sheltered by the coastal morphology, the rough seas offshore generate a swell that can make mooring unstable. With forecasts exceeding Force 4, returning to Porto Malfatano is highly recommended.

Libeccio (SW)

The most dangerous wind for this location. The bay is completely exposed to the South-West. The sea funnels into the entrance, generating steep waves. Golden Rule: If a Libeccio wind exceeding Force 3 is forecast, leave the anchorage immediately.

Skipper's Tip

If the air suddenly becomes crystal clear and the peaks of the Sulcis mountains appear very close, the Maestrale will arrive within 6 hours. It is time to plan your return trip.

Anchoring and Environmental Protection

Anchoring on Posidonia oceanica is an environmental crime punishable by fines of up to €30,000. The seagrass meadow is easily identifiable as dark patches on the seabed.

Recommended Technique:

  1. Locate the white sand patch in the center of the bay.
  2. Drop the anchor (preferably a Delta or Rocna type).
  3. Pay out chain at a 5:1 ratio to the depth (e.g., 25m of chain in 5m of water).

Final Notes for Boaters

  • Arrival Time: Before 10:30 AM to secure the best anchoring spot on the sand.
  • Wastewater Discharge: Strictly prohibited throughout the SCI (Site of Community Importance) area.
  • Going Ashore: Permitted only on the main sandy shoreline during July and August.
