Securing a Vessel for Passage
This element focuses on the practical and theoretical knowledge required to ensure a vessel is properly secured for sea, including maintaining watertight and weathertight integrity through systematic checks of all openings and structures, as well as securing all movable items and cargo to prevent shifting during passage. Emphasis is placed on adherence to industry standards and reporting procedures to uphold safety and regulatory compliance.
Assessment criteria
Quick Revision Summary (Key Takeaway)
The Open Awards Level 2 Certificate in Maritime Studies: Able Seafarer (Deck) (RQF) covers essential deck operations, safety procedures, and seamanship skills required for entry-level deck roles. This qualification focuses on practical competencies such as mooring, cargo handling, navigation watchkeeping, and emergency response, preparing learners for careers as able seafarers on merchant vessels.
Topic Overview
The Able Seafarer (Deck) qualification is a vocational certificate that equips learners with the practical skills and knowledge needed to work as a deck rating on merchant ships. It covers a wide range of topics including seamanship, safety, cargo handling, and environmental protection. This qualification is recognised by the Maritime and Coastguard Agency (MCA) and is a key step towards a career at sea.
The course is designed to be hands-on, with a strong emphasis on safety and operational procedures. Learners develop skills in mooring, anchoring, steering, and maintaining deck equipment. They also learn about the International Regulations for Preventing Collisions at Sea (COLREGs), firefighting, and life-saving appliances. This knowledge is essential for ensuring the safe and efficient operation of a vessel.
This qualification fits into the wider maritime industry by providing a standardised level of competence for deck ratings. It allows seafarers to progress to higher qualifications, such as the Level 3 Certificate in Maritime Studies, and eventually to officer roles. The skills learned are transferable across different types of vessels, including cargo ships, tankers, and passenger ferries.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a thorough understanding of weathertight versus watertight definitions and illustrating how each is maintained on board through examples such as hatch covers, door seals, and shell openings.
- Award credit for accurately describing the process for taking soundings of tanks, bilges, cofferdams, void spaces and chain locker, including the use of appropriate tools, safety precautions, and proper recording of readings.
- Award credit for identifying typical damage scenarios (collision, grounding, contact) and corresponding checks on hatches, tank lids, doors, air and sounding pipes, with a clear explanation of associated reporting arrangements.
- Award credit for correctly recognising and interpreting hazardous signage (IMDG, COSHH) and explaining safe stowage requirements and emergency procedures as per industry guidelines.
- Award credit for describing comprehensive checks on lashings and securing devices for deck cargo, equipment in store rooms, holds, cargo spaces, steering and engine room spaces, and additional precautions during heavy weather, including restriction of access to weather decks.
- Award credit for accurately describing weathertightness (protection against spray and rain) versus watertightness (resistance to submersion) and explaining routine maintenance tasks that preserve hull integrity.
- Demonstrate correct procedures for inspecting and securing all openings, including shell doors, hatches, and air pipes, and for identifying faults such as corrosion or damaged seals, with clear reporting protocols.
- Carry out a systematic check of lashings and securing devices for deck cargo, stores, and equipment across all compartments, referencing relevant signage and hazard guidelines for safe stowage.
- Explain the rationale for additional precautions during heavy weather, including restricting access to weather decks, re-tensioning lashings, and verifying watertight closures.
Assessment Guidance
Guidance for achieving higher grades
- 💡Use precise maritime terminology such as 'dogging down hatches', 'frapping lines', or 'tween deck' to demonstrate professional language in written assignments or oral questioning.
- 💡When outlining inspection procedures, adopt a systematic, logical sequence (e.g., start from the forecastle, proceed to the main deck, then below waterline spaces) to ensure no area is missed and to mirror real-world practices.
- 💡Reference the ship’s Safety Management System, the Code of Safe Practice for Cargo Stowage and Securing (CSS Code), and SOLAS requirements in your responses to show regulatory awareness and depth of knowledge.
- 💡During practical assessments, verbalise your checks and findings clearly—simulate reporting to a senior officer, mentioning the nature of any fault, its location, and the action taken—this aligns with real-world accountability.
- 💡Always structure answers to cover both visual inspection and physical testing (e.g., try hand-tightness on dogs before visual check of gaskets).
- 💡Use precise terminology when describing checks; for instance, specify 'check sounding pipe caps are present and tightly sealed' rather than just 'check pipes'.
- 💡When addressing securing cargo, reference specific regulations (IMDG, COSHH) and practical measures like using chocks, lashings, or dunnage to prevent movement.
- 💡For heavy weather scenarios, link each precaution to a specific risk, such as 'restrict deck access to prevent crew being swept overboard by green seas'.
- 💡Use correct maritime terminology in your answers, such as 'starboard', 'port', 'bow', 'stern', 'bollard', and 'winch'.
- 💡Always refer to safety procedures and regulations, such as SOLAS and MARPOL, when answering questions about operations.
- 💡In calculation questions, show all your working and include units in your final answer.
Common Mistakes
Common errors to avoid in your coursework
- Confusing weathertight (designed to withstand occasional water entry under defined head of water) with watertight (structurally preventing water ingress under all normal conditions), leading to inadequate sealing of openings.
- Neglecting to verify that sounding pipe caps and air vents are securely closed and free from damage, which can compromise watertight integrity and lead to inaccurate soundings.
- Assuming that lashings are adequate without checking for wear, correct tension, or compliance with the vessel’s Cargo Securing Manual, potentially causing cargo shift.
- Failing to account for heavy weather securing requirements, such as additional lashings, storm rails, and the importance of restricting deck access, thus underestimating risks.
- Omitting to identify and report minor faults (e.g., deteriorated rubber seals on doors, corrosion around openings) on the basis that they are not an immediate threat, which can escalate into serious integrity breaches.
- Confusing the terms 'weathertight' and 'watertight', applying them interchangeably when describing closures.
- Neglecting to report minor faults or assuming they do not compromise integrity, leading to potential cumulative failures.
- Overlooking the need to check securing devices after loading or in rough conditions, assuming one initial check is sufficient.
- Failing to include chain lockers and void spaces in sounding routines, or misinterpreting unexpected readings as instrument error rather than potential leaks.
- Misconception: The able seafarer (deck) is responsible for navigation. Correction: Navigation is the responsibility of the officer of the watch; the able seafarer assists but does not make navigational decisions.
- Misconception: Fire extinguishers can be used on any type of fire. Correction: Different fire classes require different extinguishers; using the wrong one can be ineffective or dangerous.
- Misconception: Mooring lines can be handled without gloves. Correction: Mooring lines can cause serious injuries; gloves and proper PPE are essential.
