Atlantic Trade Winds KITE 3 MPH
Canaries → Caribbean. NE trades, beam reach to broad reach. ~45 days
⚡
Caribbean Transit MIXED 2.5 MPH
Island hopping to Panama. Variable winds, some calms. ~25 days
🪁
South Pacific Run KITE 3 MPH
Galapagos → Marquesas → Australia. SE trades, classic downwind run. ~90 days
⏳
Doldrums Crossing SOLAR 1.25 MPH
ITCZ transitions (2 crossings). Kite useless, solar only. ~15 days total
🪁
Indian Ocean Monsoon KITE 3 MPH
Indonesia → Madagascar → South Africa. NE Monsoon (Dec-Mar) provides downwind run. ~100 days
⚠️
Hurricane Avoidance HOVE TO
Strategic waiting in safe zones (Trinidad, New Zealand, Madagascar). ~45 days stationary

⚠️ Critical Constraints:
- Hurricane Seasons: 45 days of stationary waiting required (Caribbean: Jun-Nov, E. Pacific: May-Oct, W. Pacific: Jun-Dec, Indian: Apr-Dec)
- Indian Ocean Monsoon: Must traverse during NE Monsoon (Dec-Mar) for downwind run
- Doldrums (ITCZ): Two crossings required (Atlantic and Pacific), solar-only mode, ~15 days total
- Cape of Good Hope: Must stay north of 35°S to avoid Roaring Forties, adding distance
🌊 Speed Analysis
Your vessel's performance varies dramatically by conditions:
2.4:1
Kite vs Solar Ratio
By staying in the trade wind belts (where winds blow steadily from the east), you achieve 78% kite utilization, yielding an effective average speed of 2.1 MPH over the entire circumnavigation.
📅 Optimal Departure Window
To minimize hurricane exposure and maximize downwind efficiency:
📍
Start: December 1st, Canary Islands
Arrives Caribbean mid-January (post-hurricane), reaches Panama for February crossing to Pacific.
