Generate and adapt a sea-duty daily routine with watch rotations, sleep protection, duty handovers, internet-budgeted work blocks, and role-specific tasks. U...

Overview

Build a practical 24h onboard routine that protects sleep, keeps safety anchors, and fits real constraints (role duties, sea state, and limited internet).

Workflow

1. Capture context inputs.
2. Select watch/sleep model.
3. Generate 24h timeline.
4. Add safety anchors and handovers.
5. Add bandwidth-aware work/content policy.
6. Return concise schedule + non-negotiables.

1) Capture context inputs

Collect only required inputs:

• vessel type: cargo / tanker / offshore / yacht / fishing / ferry
• role: captain / OOW / engineer / deck crew / passenger
• timezone (IANA)
• watch model: 4/4, 3/3, 6/6, solo cycle
• start of first watch (local time)
• internet limit (GB/week)
• priorities: sleep, productivity, fitness, content, study

If data is missing, assume: 2-person 4/4, start 08:00, timezone Europe/Vilnius, 4 GB/week.

2) Select watch/sleep model

Use references/watch-models.md. Rules:

• Protect minimum 6h sleep/day, target 7h.
• Keep one uninterrupted core block >=3h when possible.
• No cognitively heavy tasks immediately after fragmented sleep.

3) Generate 24h timeline

Use scripts/build_marine_plan.py for a starter plan. Required blocks:

• on-watch blocks
• sleep/rest blocks
• meal/hydration
• weather/navigation review
• role duty block
• optional online work + posting window

4) Add safety anchors

Use references/safety-anchors.md. Always include:

• start-of-watch handover checklist
• 2-4 safety scans/day
• end-of-day log line

5) Add internet policy

Use references/internet-budgeting.md. Always provide:

• daily MB target from weekly limit
• one low-traffic day/week
• "offline-first" recommendations (downloads, no autoplay, no cloud sync on cellular)

6) Output format

Return exactly these sections:

1. Status: one line.
2. 24h Plan: bullet list HH:MM–HH:MM — action.
3. Non-negotiables: max 5 bullets.
4. Traffic budget: one line daily MB target + one line policy.

Keep it short, operational, and in the user language.
