Basic Maritime Skills and Safety: Essential Nautical Knots Every Mariner Should Master
Basic Maritime Skills and Safety: Essential Nautical Knots Every Mariner Should Master
Captain Larry O. | Waterways News | Maritime Education | Skills & Safety
Long before radar, GPS, and satellite communication came aboard, the fate of a vessel and everyone on it often rested on something far simpler: a length of rope, tied correctly. That has not changed. From the ocean-going tankers threading the Bonny and Escravos channels to the wooden passenger boats that carry commuters and traders across the creeks of the Niger Delta, knot-tying remains one of the most basic, and most essential, skills a seafarer can carry.
For Nigeria’s growing community of mariners, cadets, boat operators, and inland waterway transport workers, knot proficiency is not a ceremonial skill reserved for maritime academies. It is a practical, day-to-day necessity. A well-tied knot secures cargo on a barge navigating the Lagos–Baro corridor, holds a mooring line fast against tidal surge at a jetty, rigs a sail on a fishing canoe, or, in the worst of circumstances, becomes the difference between a rescue and a tragedy. As Nigeria pushes to expand its blue economy and strengthen safety standards across its more than 10,000 kilometres of navigable waterways, the humble knot deserves fresh attention.
Waterways News presents a curated guide to 15 essential knots that every deckhand, able seaman, bosun, officer, and sailing enthusiast should know, organised by function, and grounded in the standards promoted by the International Convention for the Safety of Life at Sea (SOLAS) and global maritime training frameworks.
Why Knot Skills Still Matter in a Modern Maritime World
It would be easy to assume that in an age of hydraulic winches, synthetic rigging systems, and automated mooring equipment, traditional knot-tying has become a relic. The opposite is true. Modern vessels, tugboats, dredgers, and passenger ferries still rely heavily on manual line handling, particularly during mooring, towing, cargo lashing, emergency drills, and man-overboard recovery operations. Equipment can fail or be unavailable in an emergency; a mariner’s hands and a length of rope rarely are.
Maritime safety regulators have also kept knot competency firmly within training curricula. SOLAS-aligned training standards, as well as the International Maritime Organization’s Standards of Training, Certification and Watchkeeping (STCW) framework, continue to require demonstrable rope-work skills for deck ratings and officers alike. In Nigeria, where the Nigerian Maritime Administration and Safety Agency (NIMASA) and the National Inland Waterways Authority (NIWA) have intensified safety campaigns following a string of boat mishaps on inland waters, basic seamanship skills, knot-tying chief among them, are being re-emphasized as a frontline defence against accidents.
Below is the full breakdown.
1. Basic and Stopper Knots
These are the building blocks of seamanship, the first knots any cadet learns, and the foundation for more advanced rigging work.
Overhand Knot: The simplest knot of all, formed with a single loop and pull-through. It is rarely used alone for critical loads but forms the basis of many other knots and is useful for quick, temporary stops on a line.
Figure-Eight Knot: Widely regarded as one of the best stopper knots available. Tied at the end of a rope, it prevents the line from slipping through a block, pulley, or fairlead. Unlike the overhand knot, it does not jam under load, making it far easier to untie after use, a critical advantage when working under time pressure or wet conditions.
Granny Knot: Often confused with the reef knot because of its similar appearance, the granny knot is structurally unstable and prone to slipping or jamming unpredictably. Maritime trainers consistently flag it as a knot to avoid for any load-bearing or safety-critical application. Its inclusion here is a caution, not a recommendation: know it so you can recognize. and avoid it.
2. Joining and Binding Knots
This category covers knots used to connect two ropes, bind objects together, or attach a line to a fixed point.
Square Knot (Reef Knot): A traditional knot for joining two ropes of similar diameter, historically used to reef or furl sails. It should never be relied upon for critical loads or dissimilar rope thicknesses, as it can slip or capsize under strain, but remains useful for general lashing and securing tasks.
Sheet Bend and Double Sheet Bend: The go-to knot for joining two ropes of different thickness or material, a common scenario aboard vessels where synthetic and natural fibre lines may need to be connected. The double sheet bend adds an extra wrap for improved security, particularly useful when the ropes involved are slippery or under heavier load.
Fisherman’s Knot: A reliable joining knot traditionally used by anglers and boat crews to connect fishing lines or lightweight ropes. It consists of two overhand knots tied around each other, which then draw tight against one another under tension.
Common Whipping: Not strictly a knot but a binding technique, whipping is used to bind the end of a rope and prevent it from fraying or unraveling, an essential piece of rope maintenance aboard any working vessel.
Cow Hitch: A quick and simple hitch for attaching a rope to a post, ring, or rail. It is fast to tie and untie, making it useful for temporary securing tasks, though it is not recommended for heavy or safety-critical loads due to its tendency to slip under certain angles of pull.
Clove Hitch: A staple aboard any vessel, the clove hitch is used to quickly secure a rope to a post, piling, or rail, commonly seen in fendering and temporary mooring work. It ties and releases quickly but can slip if not backed up with a half hitch, particularly under a fluctuating load such as that caused by wave action against a jetty.
Heaving Line Knot: Used to add weight to the end of a heaving line, allowing it to be thrown further and more accurately, an indispensable skill during mooring operations, when a line must be passed from ship to shore or between vessels, sometimes across a significant gap of open water.
3. Special Purpose Knots
These knots serve more specific and often, more critical functions, from creating secure loops to shortening damaged sections of rope.
Bowline: Frequently called the “King of Knots,” the bowline creates a fixed loop at the end of a rope that will not slip or tighten under load, yet can still be untied easily even after being subjected to heavy strain. It is used everywhere from securing a line around a bollard to forming a loop for rescue operations, and remains one of the first knots taught to any new seafarer for good reason.
Running Bowline: A variation of the standard bowline that creates a loop capable of tightening around an object, functioning similarly to a lasso. It is useful for retrieving objects from the water or securing loads that require a self-tightening loop.
Bowline on a Bight: Formed in the middle of a rope rather than at its end, this knot creates two secure loops and is particularly valuable in rescue situations, where it can be used as an improvised sling or harness to lift or lower a person safely.
Sheep-shank: A knot used to temporarily shorten a length of rope without cutting it, or to bypass a damaged or weakened section. While less commonly used in routine operations today, it remains a valuable skill for emergency situations where rope is limited and a section is compromised.
Building the Habit: Practice as a Safety Culture
Knowing a knot’s name and shape is only the first step. Maritime trainers and safety officers consistently stress that speed, muscle memory, and the ability to tie knots correctly under pressure, in darkness, in rain, on a pitching deck, or with cold or gloved hands, are what actually separate a competent mariner from a merely informed one. This is why SOLAS-aligned training standards recommend that knot-tying be built into regular safety drills rather than treated as a one-time academy exercise.
For operators along Nigeria’s inland waterways, where NIWA has reported that wooden boats make up the overwhelming majority of vessels in service, and where safety agencies have pushed initiatives ranging from life jacket distribution to stricter enforcement of navigation standards, reinforcing basic seamanship skills like knot-tying fits into a broader push to reduce boat mishaps and improve safety outcomes for both crew and passengers.
Whether you are a cadet preparing for certification, an able seaman refreshing core skills, a bosun training junior crew, or simply a sailing enthusiast, the 15 knots outlined above form a solid, practical foundation. They are inexpensive to learn, require no special equipment beyond a length of rope, and remain as relevant today as they were in the earliest days of seafaring.
Strong knot skills are, in the truest sense, timeless.

IMO Sets First-Ever Two-Year Theme for World Maritime Day, Tasks Member States to Move “From Policy to Practice”
IMO Sets First-Ever Two-Year Theme for World Maritime Day, Tasks Member States to Move “From Policy to Practice”
By Emetena Ikuku | Waterways News
The International Maritime Organization (IMO) has adopted “From Policy to Practice: Powering Maritime Excellence” as its World Maritime Day theme for both 2026 and 2027, marking the first time in the observance’s history that a single theme will run for a full two-year cycle instead of the usual one.
The decision was endorsed by the IMO Council at its 134th session in London, held from July 7 to 11, on a proposal from IMO Secretary-General Arsenio Dominguez. World Maritime Day will continue to fall on the last Thursday of September each year, with 2026 and 2027 both marked under the same theme.
IMO explained that the extended timeframe reflects a deliberate shift in focus, from the adoption of new rules to ensuring those already on the books are actually applied. According to the organisation, “From Policy to Practice” speaks to its core mandate: making sure that conventions, codes and guidelines agreed at the international level are translated into national law, enforced consistently, and embedded in the daily operations of ports, ships and administrations worldwide, rather than existing only on paper.
The “Powering” element of the theme points to the practical support IMO intends to deploy to help member states close that implementation gap, including technical assistance, training programmes, capacity-building and knowledge-sharing partnerships aimed at strengthening maritime administrations and port state control regimes. “Maritime Excellence,” the organisation says, describes the end goal: a shipping industry that is safe, secure, efficient and environmentally sound, held to the highest international standards and committed to continuous improvement.
In a video message announcing the campaign, Dominguez said the true test of the global regulatory framework lies in implementation, stressing that when the industry talks about “practice,” it is ultimately talking about people, and that IMO is committed to powering that transition through direct technical cooperation and support.
IMO has invited member states, industry stakeholders and the public to join the campaign using the hashtags #WorldMaritimeDay and #MaritimePolicytoPractice as national and regional activities roll out over the two-year period.
Nigeria Watch
For Nigeria, a theme built entirely around closing the gap between policy and practice lands close to home. It is, in many ways, the exact fault line this desk has tracked for years across the country’s maritime sector: regulations that exist in full on paper but struggle to survive contact with implementation on the water.
The theme’s emphasis on national legislation, enforcement and day-to-day operations speaks directly to open questions around NIMASA’s cabotage regime and the long-delayed disbursement of the Cabotage Vessel Financing Fund (CVFF), to the jurisdictional tug-of-war between NIWA and LASWA over inland waterways regulation even after Supreme Court intervention, and to the practical rollout of the NPERA Act now that the agency has formally begun operations. Each of these is, at bottom, a policy-to-practice story still waiting for its second half to be written.
It also speaks pointedly to the everyday reality of Nigeria’s informal and small-scale waterway operators, represented by bodies like WABOTAN and ATBOWATON, who often experience federal and state maritime policy not as technical assistance and capacity-building, but as enforcement action with little of the promised support attached. If IMO’s two-year campaign is genuinely about “translating international rules into action at sea and on shore,” as the organisation puts it, Nigerian regulators have an unusually clean, IMO-endorsed framework to be measured against between now and 2027, and operators on the inland waterways will be watching to see whether “powering” the transition includes powering their own long-stalled asset financing and safety upgrades, not just headline compliance targets aimed at the deep-sea fleet only.
With Nigeria holding a seat on the IMO Council, the country also carries a diplomatic stake in how visibly it is seen to be putting the theme into practice at home over the coming biennium.

Oyetola Sets Up Technical Committee to Fast-Track Fish Production, Cut Nigeria’s Import Bill
Oyetola Sets Up Technical Committee to Fast-Track Fish Production, Cut Nigeria’s Import Bill
By Ighoyota Onaibre | Waterways News
The Federal Ministry of Marine and Blue Economy has begun moving from policy talk to implementation on fish production, with the Minister, Dr Adegboyega Oyetola, inaugurating a Technical Committee on Accelerating Fish Production in Nigeria in Abuja on Thursday.
Oyetola said the committee’s job was to convert existing recommendations into coordinated action that can deliver measurable gains in the country’s fisheries and aquaculture sector, rather than produce another policy document.
He noted that fish remains a major source of animal protein for millions of Nigerians, and that the fisheries and aquaculture value chain sustains livelihoods across production, processing, marketing and transportation. But domestic output still falls well short of national demand, he said, with knock-on effects for food security, household incomes and the country’s foreign exchange position.
The Minister listed the sector’s key constraints as high production costs, particularly feed, poor access to quality fish seed and broodstock, weak fish-health and biosecurity systems, post-harvest losses, and inadequate cold-chain and storage infrastructure. He also pointed to limited access to affordable finance, thin research and data systems, and gaps in standards, traceability and market development.
Oyetola said the recent transfer of fisheries and aquaculture functions to his ministry gave the sector a stronger institutional platform, and reaffirmed government’s commitment to growing sustainable domestic production and cutting Nigeria’s reliance on fish imports.
The committee’s work builds on a strategic roundtable the ministry convened with the National Institute for Policy and Strategic Studies (NIPSS) on October 29, 2025, which produced a set of recommendations on production and value-chain bottlenecks. Members have been asked to test each recommendation against existing national policy, laws and institutional mandates, deciding whether it should be adopted, refined, folded into current programmes, studied further, or dropped and to map ongoing public, private and development-sector initiatives so scarce resources are not duplicated.
Oyetola said the committee’s final output must include a clear implementation roadmap and matrix covering priority interventions, responsible institutions, timelines, indicative costs, funding options, performance indicators and required approvals, along with credible entry points for private investment, public-private partnerships and development finance.
The Permanent Secretary of the ministry, Mrs Fatima Sugra Mahmood, who chairs the committee, pledged a thorough review process aimed at practical, measurable interventions. Prof Akintola Shehu Latunji of Lagos State University, speaking for other members, thanked the Minister and committed the committee to working with stakeholders to boost fish production nationwide.
Other members include Mr Omoragbon Wellington and Mr Garba Usman of the Federal Department of Fisheries and Aquaculture; Prof Ayo Omotayo of NIPSS; Prof Sule Abiodun of the Nigerian Institute for Oceanography and Marine Research; Prof Sadiku Suleiman Omeiza of the Federal University of Technology, Minna; Bayelsa State’s Commissioner for Marine and Blue Economy, Dr Faith Izibenua Zibs-Godwin; Dr Charles Okaga, Technical Assistant to the Minister; Dr Ebinimi Ansa of the Fisheries Society of Nigeria; Mr Onoja Sunday of the Catfish Farmers Association of Nigeria; Mr Mashi Gabriel Sani of the Fisheries Cooperative Federation of Nigeria; Mr Remi Ahmed of the Tilapia Development Association of Nigeria; and Dr Charles Iyangbe of WorldFish Nigeria.
The committee has eight weeks to submit its report.
Nigeria Watch
Fish production is not a subject Waterways News covers often, but it sits squarely inside the blue economy mandate this Ministry now carries and it is worth watching for the same reason CVFF, NPERA and NIMASA reforms are worth watching: Nigeria has no shortage of roundtables, committees and roadmaps; what it has historically lacked is follow-through.
Oyetola’s own framing, “your assignment is not to develop another policy”, reads as an implicit acknowledgment of that pattern, and an eight-week deadline is a useful marker for readers to hold the ministry to. The emphasis on cold-chain and storage infrastructure, and on post-harvest losses, also echoes concerns Waterways News has tracked on the inland waterways side, where WABOTAN and ATBOWATON operators regularly cite poor storage and logistics as a drag on returns from fish and other perishable cargo moved by water. A serious fisheries roadmap that funds cold-chain and market infrastructure along riverine routes would have direct relevance for the informal waterway transport economy this desk covers closely.
Whether this committee’s report becomes another shelved document or an actual funding and implementation pipeline is the story to follow when the eight weeks are up.

NPERA Charges Staff on New Mandate as Akutah Eyes $1 Trillion Economy, Pledges Harmony with Sister Agencies
NPERA Charges Staff on New Mandate as Akutah Eyes $1 Trillion Economy, Pledges Harmony with Sister Agencies
By Okeoghene Onoriobe | Waterways News
The newly transitioned Nigeria Ports Economic Regulatory Agency (NPERA) has told its workforce that the agency’s expanded powers must translate into measurable gains for the maritime sector, as its chief executive moved to calm anxieties over possible turf conflicts with other port institutions.
Speaking at a townhall session with staff, NPERA’s Director-General, Dr Pius Akutah, said the agency’s new statutory footing, created under the Nigerian Ports Economic Regulatory Agency Act, 2026, leaves no room for institutional rivalry, since the law spells out NPERA’s role as the ports’ economic regulator distinctly from the operational and infrastructure mandates held by other agencies.
Akutah described the President’s assent to the Act as a breakthrough for the maritime industry, saying the reinforced regulatory powers position the agency to curb sharp practices and drive efficiency at the ports. He urged staff to raise their professional standards to match the agency’s new responsibilities, and said NPERA intends to work closely with the Nigerian Ports Authority (NPA) in particular, alongside other sister agencies, to deepen reforms and improve service delivery across the ports.
He linked the agency’s broadened mandate directly to government’s wider ambition of building a $1 trillion economy, arguing that a more predictable and business-friendly port environment is central to that goal.
The remarks follow the formal transition of the Nigerian Shippers’ Council (NSC) into NPERA, a process more than a decade in the making. NPERA Governing Board chairman, Dr Ibrahim Shema, has described the change as a structural separation of economic regulation from the NPA’s landlord and infrastructure functions, with NPERA’s approach to be anchored on transparency, fairness, predictability, efficiency and accountability. Both officials have stressed that NPA retains its infrastructure role while NPERA takes on tariff regulation, licensing, competition oversight and commercial dispute resolution.
NIGERIA WATCH
Every new regulator in Nigeria’s port and maritime space arrives with the same reassurance: this one won’t fight the agencies already there. NPERA’s rollout is no exception, and the emphasis on “harmony” with NPA is itself a tell — it signals that stakeholders, including operators and shippers who have lived through NIMASA-NPA and NIWA-LASWA turf disputes, are watching closely for the first sign of overlap.
For the informal and small-scale end of the water transport economy that Waterways News tracks — the operators represented by WABOTAN and ATBOWATON — NPERA’s mandate is, on paper, encouraging. A regulator empowered to resolve commercial disputes and rein in unapproved charges could, if it functions as designed, extend some protection to smaller port users who have historically had the least leverage against terminal operators and shipping lines. But the sector’s experience with the CVFF disbursement saga is a caution against measuring reform by its founding rhetoric alone. An agency can be transparent on paper about “five principles” and still take years to deliver anything an ordinary operator can point to.
The real test for NPERA, as with NPERA’s own DG has implicitly acknowledged by tasking his staff before the agency has even settled into its new powers, will be whether tariff clarity and faster dispute resolution reach beyond the big shipping lines and terminal operators to the smaller players who move goods and people along Nigeria’s waterways every day. Waterways News will be watching how NPERA’s mandate is implemented in practice, not just how it is announced.
