Hey Product Hunt 👋

I'm Chris. I sail a few times a year, and for a long time I was the guy on deck who didn't know things.

Someone shouts a word I've never heard. I can't tell a fishing boat lights from a tug with a tow. A buoy sits off the bow and I have half a memory of which side to pass it. Every answer existed, just buried in a 400-page handbook or a PDF. By the time I found it, the moment was over.

So I built the thing I wanted in my pocket. Modern, digital, driven by UX and usability needs of modern recreational sailor.

Ship Lights: pick a vessel, see it from all sides with the actual lights glowing where they sit.
Flags, buoys, shapes, clouds: every one house-drawn or shot on real water so you can relate to them 100%
Dictionary: searchable sailing jargon, English and Polish for now
Radio Help: ready-to-read VHF scripts, so neither Mayday or asking marina for a spot isn't something you improvise.

Free to use. Ahoy Pro is a one-time purchase that unlocks full offline access, because out there the signal goes first. I plan tu put some more premium edu materials there too as a collab with sailing schools.

If you sail and see how Ahoy may be an app for you - I'm here ready to go 🌊

Safe travels and favourable winds!
