Raft Engines and Navigation Guide: Sails vs Engines, Receivers, Antennas, and Sailing Between Islands
Raft navigation runs in three stages: a free but wind-limited sail, a receiver with three antennas and a battery that turns drifting into coded travel, and engines from the Vasagatan that push against the current. This guide covers sail limits, receiver placement and four-digit codes, the engine recipe and the 100-foundation rule, plank versus biofuel, and efficient island-to-island sailing.
