A private operating record for M/Y Meridian Hour: what's installed, what's running on borrowed time, what's certified, and what a new captain would need to know on day one.
Specification
Every registered vessel gets one living record. It organizes machinery, certificates, maintenance, and crew knowledge around the hull itself, so that record, not any one person's memory, is what a new captain or a buyer's surveyor actually gets handed.

What's aboard, and how it's tracked
Main engines and gensets are serviced on running hours, not the calendar, that's the one structural fact that makes a yacht different from a house. Select any system for its full record.

The knowledge that walks off the passerelle
Most yachts change captain every few years, and the chief engineer's memory usually leaves with them. That handover problem is more acute on a vessel than in any house, it's the reason this record exists.

What would be lost at the next handover
Port genset cold-start purge
Requires a 90-second manual fuel purge before the first start after any shutdown longer than 48 hours, or it won't catch. Not in the Kohler manual — learned through experience and passed captain-to-captain verbally until it was logged here in Nov 2024.
Logged by Marcus Oduya, Chief EngineerPort watermaker feed sequence
The feed valve must be opened before the pump is energized, or the low-pressure switch trips and locks out the unit. A workaround from a previous engineer, not documented by Sea Recovery.
Logged by Marcus Oduya, Chief EngineerStarlink handoff drop off Sardinia
Starlink drops for roughly 40 seconds during satellite handoffs in this specific stretch of the Western Med. Confirmed by two prior IT contractors as a known regional issue, not a fault — VSAT picks up the gap automatically.
Logged by Rhys Calloway, CaptainAnchor chain marking scheme
Chain is marked in a non-standard 10-metre scheme specific to this vessel rather than the usual 25-metre yard marks, left over from the 2022 refit. Every new deckhand has to be told this by hand.

Q: What are the running hours on the port main engine, and when is the next service?
A: 5,238 hours. The next scheduled 1,000-hour service is at 6,000 hours — approximately 762 hours, or about 9 weeks of typical cruising, remaining.
Source: Port Main Engine — Machinery LogMore example questions
When does the EPIRB hydrostatic release expire?
The HRU expires in August 2026 — about 3 weeks out. It was last replaced in August 2024, on its standard 2-year cycle. The EPIRB's battery has a separate expiry in March 2028 and is not due.
Source: EPIRB & Distress Beacons — Safety RecordWhat's the vessel's VAT status?
EU VAT was paid via Malta import in 2016, so the vessel is eligible for unrestricted EU cruising. There is no Temporary Admission in effect.
Source: VAT Status & Temporary Importation — Document RecordWho serviced the watermaker last, and what did they find?
Chief Engineer Marcus Oduya inspected it in April 2026 and flagged the port membrane's output trending down — salinity is still within spec, but he recommended an early replacement, likely due to local marina water quality rather than a fault.
Source: Watermakers — Machinery LogWhat's logged about the port genset cold start?
It needs a 90-second manual fuel purge before the first start after any shutdown longer than 48 hours, or it won't catch. That isn't in the Kohler manual — it was learned through experience and only written down in November 2024.
Source: Handover Notes — Chief EngineerWhat Astra Doesn't Do
Astra Intelligence answers from this vessel's own records and always shows its source. It does not offer navigational, stability, or compliance advice, and it does not certify that any repair or procedure is safe to perform — the engineering team and the vessel's official documentation remain the authority on anything safety-critical.
Change of command & ownership transfer
This score reflects how much of the vessel's operating knowledge is written down versus held only in someone's memory, not the boat's condition or value. See Crew & Handover for the detail behind it.
