2026 RMI yacht-code applicability, MLC water and welfare obligations, with evidence gaps transparently marked for code-specific review.
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”.
The RMI Yacht Code 2026 entered into force on 1 January 2026. It covers distinct commercial, private, PAXY and limited charter use cases. Marine Notice 7-044-1 (Jul 2024) implements MLC Title 3 and specifically cross-refers to 2021 Yacht Code in its historical references; the yacht’s governing 2026 code requirements therefore need to be checked directly. The below register does not invent an exact RMI laboratory interval or mandatory chlorine concentration.
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.

Treatment
Check treatment design, approvals and performance verification; do not assume automatic RMI authorisation for any named biocide or technology.
When in scope: Installed UV/chemical/silver/chlorine or other treatment
Evidence requested: RO/flag acceptance, validation and calibration
Maintenance
Set vessel-specific cleaning, flushing and biofilm control intervals aligned to risk and component manufacturer instructions.
When in scope: Freshwater tanks, low-use outlets and showers
Evidence requested: PMS, cleaning logs and sample results
Sampling
