Import from Furuno (GPX)
Export waypoints from the Furuno TZtouch via USB (Import/Export →
GPX) and drop the file here. Rhumb keeps the original name,
symbol, and color codes so you can decode them once and bulk-label
every matching mark. Cruise tracks are skipped on purpose.
Decode codes
Each row is a unique symbol/color combo from your imported marks.
Set what it means once and apply to every matching mark. The
legend is remembered for future imports.

Heads up. Mexican regulations reserve billfish for sport fishing only,
and the lead-boat policy on this app is catch-and-release for anything under tournament-class
(300 lb). Consider logging this as Released.
