Solve wind and current problems quickly at sea

A multi-use navigation slide rule – ideal for storm evasion, wind vectors, fuel use, and more.

The Weems & Plath Vectormaster is a versatile circular slide rule designed to solve a wide range of navigation problems quickly and accurately. With the position of a storm and its speed and direction, the Vectormaster helps you calculate the optimal course to maximise your distance from danger.

This two-sided tool is equally valuable for routine calculations at sea – including time, speed, and distance, fuel consumption, and conversions. By rotating the dial on the face, navigators can quickly solve problems involving vectors such as current sailing, true wind direction and force, or expected apparent wind on alternative headings. Its durable PVC construction makes it a reliable companion on any voyage.

  • Two-sided circular slide rule for rapid vector solutions
  • Ideal for storm avoidance, current sailing, wind calculations, and more
  • Also solves time, speed, distance, fuel, and conversion problems
  • Made from sturdy PVC with instructions on the back
  • Covered by Weems & Plath’s Limited Lifetime Warranty
