Modernising the requirements and removing safety gaps

The proposed new standard updates the requirements for watertight and weathertight integrity to reflect current technologies and to align with current international standards and best practice. It is a performance-based standard, with multiple options for compliance to address a number of safety issues with the current requirements, including over-loading. 

The key proposed changes:

New freeboard mark 

New freeboard mark required for vessels ≥12 metres. (Not required for passenger vessels and larger workboats that are already required to have a load line).


Loading capacity placard may be used for vessels <12 metres

On smaller vessels, where a freeboard mark would not be seen on the hull, a maximum loading capacity placard may be used. The placard must be visible, preferably in the cockpit or near the main steering position in a prominent position.

The placard contains the same information that must already be carried under NSCV C6C: Stability tests and stability information.

Other proposed requirements
  • Alignment with international standards for windows and portlights, marking of doors, doors and hatches, valves and through-hull fittings and drain plugs.
  • Rapid drainage requirements. Additional flexibility for designing and calculating rapid drainage. Multiple options for freeing ports and scuppers (drains) to provide rapid drainage for decks and enclosed spaces. A simple and practical option has been added for calculating freeing port areas for vessels <12 metres and a simplified time to drain option for vessels <24m in length.
  • Improved and simplified approach to flush hatches. The current Generic Equivalent Solution 2017/19 has been incorporated into NSCV C2, with simplified tables and additional notes.
  • Sliding wheelhouse door for fishing vessels ≥12 metres. New proposed requirement for some fishing vessels to have a sliding door to allow for escape in the event the vessel capsizes or is swamped.
  • Clarification for:
    • the assessment of watertight and weathertight components, to ensure consistency across the industry.
    • installation testing and verification of watertight and weathertight components, to ensure consistency across the industry.
    • material standards for seacocks and drain plugs for vessels <24 metres. Also allows the use of modern materials like polymer in certain places when manufactured to ISO 9093.
