Radar Performance Tests

Radar Performance Comparison

Use this calculator to compare real-time performance graphs on different model, motor, propeller, and load combinations. This real-time data was collected using Stalker Radar connected to a laptop running special software.

Top speed runs are taken with the boat running at full speed toward a stationary radar gun from two directions. With the radar unit set up on a stationary platform and not in the boat, tests have proven to be more accurate and more repeatable.

Acceleration tests are taken with the boat running away from the radar gun and are represented by a curved line starting at zero.

Ski Tests are taken to compare the boat's performance using different propellers pulling a skier. For accuracy and repeatability in the ski test, a certified ski drone is used to simulate the load of an average-weight slalom skier. Ski tests are performed from a standing start in deep water with the boat loaded as indicated in each test.

Tests shown are for information only and may not represent the performance of your particular model boat.
