About Nav Lights

What this tool does

Marine tools calculate hull speed, fuel burn rate at various RPMs, anchor rode length, displacement, sail area, tide times, and sea distances between ports.

Why use this tool

Boating safety depends on correct calculations. Not enough anchor rode in a squall means dragging anchor. Underestimating fuel burn means running dry offshore. These tools help you plan passages with proper safety margins.

How it works

Hull speed uses the formula 1.34 x sqrt(waterline length in feet). Anchor rode applies the 7:1 scope ratio for moderate conditions. Fuel burn estimates interpolate from engine RPM and consumption curves.

Pro tip

In heavy weather, increase your anchor scope to 10:1 or more. The holding power of an anchor depends almost entirely on the angle of pull, and more rode keeps that angle close to horizontal.
