Your boating history is already out there.

Bring tracks, photos and written memories together in Log. Start with one outing, see what it becomes, then bring in more years.

Bring in my history

What do you have?

Tracks from another app or an old device
  1. Find a GPX export or ZIP of tracks from your navigation app. Keep the original file unchanged. Exporting from the Navionics app gives you one big file with no extension at all — that is normal, and it is explained here.
  2. Sign into Log → + Add to your log → Track files. Choose the export, even if its filename has no extension.
  3. Review the proposed outings, duplicates and possible drives. Choose whether to preserve an unchanged private original, then import your selection.
  4. Open a saved outing to see its track and replay. Use Overview to explore your years on the water.
Photo albums, including days without tracks
  1. Choose one small album. Download or export selected originals from your own library. An album link alone does not give Log access to its photos.
  2. Open + Add to your log → Photos. Choose up to 24 JPEG, PNG or WebP files. JPEG metadata supplies capture dates and locations when present; other files may need dates you confirm.
  3. Confirm the boating day and select each photo you want to include. Missing dates are questions, never replaced with file modification dates. GPS is optional.
  4. Review the proposed days. Choose an existing private outing to add evidence, or create a reconstructed photo day. Save only the selected days and reduced image previews privately.
  5. Open the saved outing. Retrying the same batch does not duplicate days or previews; a changed batch or conflicting date requires review.

Photo days carry source references and uncertainty, with no inferred route or credited hours. Photos start private. An optional album reference may travel if you later share the outing. HEIC, ZIP and sidecar metadata need preparation first; retain those originals.

Recover days from my photos
A notebook, spreadsheet or remembered adventure
  1. For a spreadsheet, open + Add to your log → Something written → A spreadsheet, upload CSV and map the columns. No assistant or custom tool is required. For one remembered outing, choose Something written → A day I remember. For a larger log, ask your AI assistant to read selected rows or help transcribe a few pages, using the prompt below.
  2. Have it prepare Log history JSON, preserving source references and listing uncertainty. It can put this directly in chat.
  3. Open + Add to your log → Something written → From my AI assistant. Paste the text or choose its JSON file. Press Review these days.
  4. Check dates, notes and same-day outings. Choose an existing private outing to add notes, or create a written day. Save selected records privately.

Import boating history with AI (experimental)

Ask an AI assistant to look through information you already have — such as email, calendar, files or photos — and propose boating outings for your Log. It comes back with dated days, each linked to the original email, photo or file, for you to check before anything is saved.

One prompt works with any assistant: it searches whatever yours can reach and says so if it can reach nothing. Assistants that run code (Claude Code, Codex, Gemini CLI) can also save straight into Log: copy the prompt from inside Log (+ Add to your log → Import with AI → Start AI import) so it carries a connection code.

It gives your assistant permission to search your own accounts — delete that sentence to be asked first. When it hands back a block, paste it at log.boating.systems/?import=written.

If your assistant asks what format Log expects

The prompt already includes the format. If it wants more, hand it the guide as text rather than a link: assistants rightly treat fetched web pages as information, not instructions, and some report the link as “blocked”.

Browser assistants use Log directly, in your signed-in tab. Your own uploader needs a connection code from Account → Connections.

Imports start private. Sharing a trip never shares the original-file library. Sources and uncertain facts remain distinguishable from measurements.
