🗺️ 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
