Airmar Deadrise Angle Finder - Accuracy of ± 1/2°

The Airmar Deadrise Angle Finder is a precision measurement tool built for anglers, boat builders, and marine technicians who need to verify hull deadrise angles with confidence. This compact instrument eliminates guesswork, allowing you to measure deadrise at the transom or anywhere along the hull to confirm structural integrity or compare performance characteristics between boats.

Built by Airmar—a leader in marine electronics and precision instruments—the Deadrise Angle Finder delivers ±1/2° accuracy, tight enough to catch meaningful differences in hull design without unnecessary expense. The tool uses a gravity-based pendulum mechanism that requires no batteries or calibration, making it reliable in any weather condition your boat encounters. Its simple analog readout is legible in bright sunlight and shade alike.

Serious boaters rely on this tool before purchasing a used vessel, after hull repairs, or when dialing in trim tabs and running gear. Naval architects and boat builders use it to validate production specs and troubleshoot handling complaints tied to hull geometry. Whether you're a charter captain evaluating a new acquisition or a restoration enthusiast verifying a rebuild, this tool is essential for accurate measurements.
