Panama MLC potable-water provision, frequent logbook inspections under MMC-275 and practical evidence requirements for yachts.
Choose only your vessel's registered flag. The crew records what can be demonstrated; Vorenico assesses the relevant evidence and identifies outstanding actions.
Vessel name, commercial or private status, length, GT, year and applicable certificate/code.
Evidence supplied, action needed, not checked yet, or not applicable with a clear reason.
Enter a logbook page, inspection date, laboratory report ID, maintenance record or corrective action. This field is text only; documents are shared separately.
Save your draft, export the CSV and share that register and source documents with Vorenico for review.
Example: Weekly water inspection → Evidence supplied → “Inspection 26 Oct 2026; deck logbook p.84; responsible engineer: Chief Engineer”.
Panama Merchant Marine Circular MMC-275, revised in December 2023, requires suitable drinking water supplied free to seafarers. It directs the master or authorised person to perform frequent documented inspections of drinking water, the water-handling/storage equipment and the galley, recording dates and results in the official logbook. The circular does not set a universal seven-day inspection interval. Panama Executive Decree 160/2021 is a separate national legal instrument: vessel-specific MLC and any applicable yacht requirements must be checked.
This evidence register is a member self-assessment tool; a recorded Vorenico technical review is not a statutory flag-state clearance.
Duty: binding if relevant regulation applies. Conditional: only under stated code and circumstances. Best practice: prudent engineering control, not an independent statutory limit. Review: confirm with the administration or applicable code before claiming compliance.
