Built for people who run the boat
Intrepid Mariner is a multi-module boating assistant for iPhone, iPad, and Mac — live NWS NEXRAD radar, nested onboard inventory, captain’s log, maintenance records, safety checklists, and professional PDF exports in one app. Your data stays on your device.
All features are free. Optional Premium entitles backup export/import and report / PDF / CSV file export only — including inventory grid sheets.
Not a chartplotter replacement — the operational brain your MFD doesn’t provide: where the spares live, what the yard needs to see, and what weather is bringing.
Everything at the helm
Animated NEXRAD, warnings. Weather or USN map modes. Marine Conditions modal (waves control) for local wind, seas, tides, and forecast.
Nested locations with photos. Inventory, loans, borrows, expenses. Vessel profile on every export.
Print-ready photo cards at 4, 8, or 16 per US Letter page — cut-apart locker tags with name and stow path. Premium for file export.
Journal, GPS position track, engine hours — free. Optional automatic logging while the app is open.
First aid, lifejackets, shore power, engine checks — plus your own lists with photos.
Problem cases with photo timelines, Customer Boat yard handoff, schedules, and shipyard-ready PDFs.
Inventory (list or grids), expenses, maintenance, checklists — PDF with thumbnails or CSV. Premium for file share.
Guided surveyor workflows — in-water or hauled. Photos, dictation, ratings, signature, signed PDF.
Claims with photo trail, mechanical defect reports, policy docs on vessel profile.
Pre-departure (free). Full-system backup (Premium). Experimental boat network (NMEA).
Why boat owners choose Intrepid Mariner
- See weather first — Animated radar and marine overlays before you cast off.
- Find gear fast — Nested lockers and photo-backed locations; stop guessing which bin holds the impeller.
- Hand off real paperwork — PDFs and CSVs with your vessel name, make, and year — ready for the yard or insurance.
- Log the boat properly — Journal, track, engine hours, and maintenance history in one place.
- Safety routines built in — First aid, PFDs, shore power, and engine checklists you can customize.
- Talk to your plotter — experimental NMEA 0183 over vessel Wi‑Fi for boat position (boat network & AIS expanding next release).
- Keep your data yours — Local storage; no cloud account required for core modules.

Honest positioning
Intrepid Mariner does not replace Navionics or your MFD charts. It wins where plotters are weak:
- Nested inventory with photos and loan tracking
- Exportable reports with vessel identity on the header
- Captain’s log, checklists, and maintenance in one native app
- Local privacy — your boat data stays on each device
