E-Numbers Explainer

Food additives are labelled as E-numbers on food packaging. This tool helps navigate what is behind these numbers.

A visual calculator of important sailing measures, from Apparent Wind Speed and Angle (AWS and AWA) to Velocity Made Good (VMG).

Teaching model with tide direction and tide speed, but BTW held fixed (static bearing to waypoint).

Fixed mark in the ground frame: live BTW, range, XTE and VMG update as the boat drifts under tide.

Barcode and ingredient checker: scan a product, look up E-numbers, or paste an ingredients list.
