AI can help with passage planning — but only inside clear boundaries.
Passage planning is not just drawing a route. It includes weather, sea state, tides, currents, daylight, fuel, water, crew readiness, vessel systems, alternates, arrival timing, communications, safety gear, documentation, and judgment.
AI tools like ChatGPT can help organize that complexity. They can help create checklists, identify missing questions, compare options, prepare briefings, and structure go/no-go thinking. But AI can also be wrong, incomplete, outdated, or overconfident.
What AI can do in passage planning
AI is most useful when it helps you organize information and think through the passage more completely.
Create structure
Turn a scattered route idea into a more organized passage planning checklist.
Surface missing questions
Identify what you still need to know before leaving the dock.
Support go/no-go thinking
Help separate favorable, cautionary, and no-go factors before departure.
Prepare arrival thinking
Organize approach, anchoring, docking, customs, communications, and backup options.
Useful AI passage-planning tasks
- Build a pre-departure checklist.
- Organize a route review by leg or waypoint.
- Create a crew briefing outline.
- Prepare a go/no-go review.
- Identify arrival planning questions.
- List official sources that should be checked.
- Prepare communications or emergency information summaries.
- Help debrief the passage afterward.
What AI cannot do safely
AI should never be treated as the authority on a passage. It does not replace verified navigation, official weather, local knowledge, emergency procedures, or the captain’s judgment.
Good uses of AI
- “What should I consider?”
- “What information is missing?”
- “What should I verify?”
- “What could change the decision?”
- “How should I organize this briefing?”
Risky uses of AI
- “Is it safe to leave?”
- “Tell me the best route.”
- “Can I ignore this forecast?”
- “Do I need to call for help?”
- “Is this official procedure current?”
Always verify safety-critical information
- Charts, depths, hazards, and navigation data
- Official marine weather and forecasts
- Tides, currents, bar conditions, and local restrictions
- Customs, immigration, and clearance requirements
- Notices to Mariners and local advisories
- Emergency procedures and communications protocols
- Medical, mechanical, electrical, and safety-critical guidance
Safe AI prompts for passage planning
Good passage-planning prompts tell AI what you know, what you do not know, and what you want it to help organize. They also instruct AI to flag what must be verified.
I am planning a passage from [departure] to [arrival] on a [boat type and length] with [crew size and experience]. Help me create a passage preparation checklist organized by weather, route, navigation, vessel systems, safety, fuel and water, communications, crew readiness, and arrival planning. Do not assume facts you do not know. List what must be verified from official sources.
Help me organize a go/no-go review for a passage from [departure] to [arrival]. Ask for missing information first. Then organize the decision into green, yellow, and red factors. Include weather, sea state, tides/currents, daylight, crew, vessel readiness, alternates, arrival conditions, and unresolved risks.
Create a departure briefing for a [boat type] leaving [departure] for [arrival]. Organize it into crew roles, watch plan, expected conditions, route overview, communications, safety gear, engine and systems checks, emergency actions, and decision triggers. Flag anything that should be confirmed before departure.
I am arriving at [harbor/port] in a cruising boat. Help me create an arrival plan covering approach hazards, timing, tide/current, communications, anchoring or docking, customs or check-in if applicable, fuel/water needs, backup options, and what should be verified from official sources.
Help me debrief a completed passage. Organize the debrief into weather and routing, vessel systems, crew performance, fatigue, communications, arrival, safety concerns, maintenance follow-up, unresolved issues, and lessons for the next passage.
The five phases of AI-assisted passage planning
Passage planning is not one task. The information a captain needs changes as the passage moves from idea to execution to follow-up.
Pre-planning
AI can help organize route options, seasonal considerations, weather windows, hazards, refuge points, documentation, fuel/water planning, crew readiness, and questions that must be answered before departure.
Departure
AI can help surface final checks, systems status, communications, harbor/tide/current considerations, crew briefing items, emergency roles, weather-window review, and unresolved go/no-go factors.
Underway
AI can help organize watch concerns, changing conditions, system checks, alternates, fatigue concerns, communications, decision triggers, and the question: “What has changed since departure?”
Arrival
AI can help prepare approach notes, harbor hazards, marina or anchorage planning, arrival communications, customs or check-in considerations, tide/current concerns, and backup arrival options.
Closure
AI can help with logs, debriefing, maintenance follow-up, unresolved issues, expense notes, safety lessons, and improvements for the next passage.
Final thought
AI passage planning is useful when it helps a captain prepare more thoroughly, ask better questions, surface missing information, and organize decisions.
It becomes dangerous when it is treated as an authority.
Used safely, AI can become a second set of eyes for passage preparation. It can help cruisers keep the right questions in front of them — but the captain remains responsible for the plan, the crew, the boat, and the decision to go.
