Practise VHF and DSC procedure.
A simulated radio environment for practising VHF procedures and DSC distress operations — no live transmission, no risk of broadcasting on Channel 16 during a drill.
Practise before you need it
Two drills.
VHF procedure simulation.
Simulated Channel 16 calls, marina berth requests, and weather broadcasts. Practise the correct phonetic alphabet, vessel name spelling, and call format without transmitting. Reviewed after each session with notes on procedure errors.
DSC distress drill.
Simulated distress calls from random vessel positions. Practise the full relay sequence — receive call, identify vessel, cross-reference chart, compose relay, transmit to coast guard. Timed, to build the reflex to do it quickly under pressure.
Why it's separate — and its one caveat
A practice tool, not a feature to unlock.
I built this to drill myself on Channel 16 calls and DSC distress relays without ever keying an actual radio. Right now it's tied to a boat record — it needs an MMSI and callsign, so opening it means signing in and adding a boat first. That's a real limit today, not a growth-funnel choice; a bare-download version is not built yet.
