A full navigation course — the last line ashore to the first line at the next port, in the order it really happens.
Most navigation training tells you what the rules say. Almost none of it tells you what the job feels like at the moment you have to do it — which order things happen in, what you write down and where, who you call and when, and what somebody checks when they step onto your bridge.
Port to Port follows a single voyage from the last line ashore to the first line at the next port, in the order it really happens rather than the order a textbook puts it in.
Every lesson pairs a narrated video with the notes, diagrams and the sources behind it — watch, then read.
Every lesson ends with something real to do. You photograph your own work — nobody marks it. The doing is the part that sticks.
Chapters unlock week by week so you build the voyage in order, at a pace you can actually keep at sea.
The duty stays; the tool does the arithmetic. You won't reduce a sight by hand — you'll know what the answer is for, and what to do when it looks wrong.
Download the videos in port and study them mid-ocean. Built for a ship's connection, not a classroom's.
Post your task to the community and see how others did theirs — a fleet of peers going through the same voyage.
19 chapters, 112 lessons — preparation, departure, the coastal watch, open sea, the ocean passage, arrival, and coming alongside. Plus dedicated lanes for bulk, tanker and container ships.








Close enough to your first trip to remember what he didn't know — and far enough ahead to have learned it. This is peer-to-peer mentorship, not a lecture: the book answer and the ship answer, side by side, told honestly.
"When the book answer and the ship answer are the same thing, I'll just teach it. When they're different, you're getting both — what people actually do, why they do it, and what it costs them."
