🗺️ 3. PASSAGE PLANNING — CAPE HORN & DRAKE PASSAGE

✅ PREPARE PER COMPANY VOYAGE PLANNING PROCEDURE

- Best Transit Window: November to March (austral summer) — longer daylight, milder storms, reduced ice risk

- Approved Cape Horn Route Options:

- Option A — Sheltered Approach: Beagle Channel → Le Maire Strait → pass 10–15 nautical miles north of Cape Horn → enter Drake Passage eastbound

- Option B — Direct Offshore: Clear of Tierra del Fuego → maintain minimum 20 nautical miles clearance from Cape Horn to avoid strong eddies and shoals

- Option C — Westbound Transit: Position well south of the Horn to counter prevailing westerlies; keep clear of Diego Ramírez Islands

- Critical Plan Details:

- Plot dedicated waypoints for: Cape Horn clearing, ice limit boundary, and pre‑planned diversion points

- Maintain safe distance from traffic separation schemes, restricted areas, and reported ice

- Adjust speed to keep critical turns and the Horn itself in daylight

- Update route at every watch; submit position and condition reports to Company as required

- Final plan reviewed and approved by Master and Company Fleet Management before departure

 

🚨 4. CONTINGENCY PLANS

✅ EXECUTE PER COMPANY EMERGENCY PROCEDURES

- Severe weather: Hold in shelter or divert early as per Company guidelines; adjust speed/heading to reduce rolling

- Equipment failure: Activate emergency systems per SMS; inform Company immediately; prepare diversion to nearest approved shelter
