About
Orsa is an educational game that teaches the basics of sailing by doing. Even if you have never been on a boat, guided practice takes you from reading the wind all the way to docking in a harbour.
SET SAIL: 14 LESSONS
Reading the wind, steering and leaving the dock, points of sail, sheets and trim, stopping and heaving to, tacking, gybing, man overboard, squalls, buoys and right of way, night sailing and lights, anchoring, docking and the return routine. Each lesson first teaches with guided practice, then lets you try the same skill on your own. Chapter questions reinforce what you learned, and a final exam earns you the "Orsa Basic Sailing" badge.
FREE SAILING ON REAL COASTLINES
Three charts built from OpenStreetMap coastline data:
• Avşa · Marmara Islands
• Fethiye Bay: Şövalye, Kızılada, Tersane, Göcek
• Gökçeada · Bozcaada
Choose your chart, boat, wind direction and strength, and time of day; find discoveries and complete route missions.
7 DIFFERENT BOATS
From the cabin training boat and a single-handed racing dinghy to the sporty Poyraz 24, the Kırlangıç 40 catamaran and the two-masted wooden gulet Karya 56 — each with its own speed, agility and stability.
KNOT TRAINING
Figure-eight, cleat hitch, clove hitch and bowline. Watch each step animated, then tie it yourself with your finger.
LIFE AT SEA
Dolphins in your bow wave, gulls overhead, loggerhead turtles in Fethiye, sunsets and night sailing.
