Welcome to the Fishing Vessel Maintenance section, here you will find information on the maintenance programme, the membership process, and how to access the maintenance database.

Fishing is one of the most dangerous jobs in the world. The worldwide most common cause of accidents on fishing vessels derives from machinery breakdowns resulting from poor maintenance. Our Maintenance Programme enhances safety and efficiency while promoting long term economic benefits.

Fishing Vessels & Boats 

Fishing vessels and boats come in various types and sizes, each designed for specific fishing methods and environments. These vessels are essential for commercial and recreational fishing activities. Here's an overview of some common types of fishing vessels and boats

Commercial Fishing Trawlers

Trawlers are large, seaworthy vessels designed for catching fish in bulk. They use trawl nets that are dragged along the ocean floor or through the water. Trawlers can be equipped for a variety of fish species, including shrimp, cod, and haddock.


Longliners are vessels equipped with long fishing lines that have multiple hooks, often used for catching species like tuna, swordfish, and halibut.

Purse Seiners

Purse seiners are typically used to catch schooling fish like tuna, sardines, and herring. They use a large net to encircle the fish, and then the bottom of the net is drawn closed to "purse" the catch.


Gill-netters employ gill-nets, which are vertical panels of netting that hang in the water. Fish swim into these nets and become entangled by their gills.

Lobster Boats

Lobster boats are specialized vessels designed for trapping lobsters in pots or traps. They are often smaller boats with hydraulic systems for lifting traps from the water.

Shrimp Boats

Shrimp boats, also known as trawlers, use large nets to drag along the seafloor to catch shrimp. They are commonly used in commercial shrimp fishing.

Tuna Boats

Tuna boats are designed for catching large pelagic fish like tuna. They are equipped with heavy-duty fishing gear, such as longlines and purse seines.

Drift Boats

Drift boats are small, flat-bottomed boats designed for fishing in rivers and streams. They are often used by anglers for fly fishing and have a unique design to navigate shallow and rocky waters.

Center Console Boats

These versatile boats are popular for recreational fishing. They feature an open deck with a central console for the helm and typically have rod holders, baitwells, and other fishing amenities.

Bass Boats

Designed for freshwater fishing, bass boats are typically small, high-speed vessels with platforms for casting and fishing for bass.

Kayaks and Canoes

Kayaks and canoes are used for fishing in calm waters. They provide a quiet and low-impact way to access fishing spots.

Commercial Fishing Vessels (Small)

Many small fishing boats are used for various types of fishing, including line fishing, pot fishing, and netting, depending on the species and location.

Sport-fishing Yachts

Sport-fishing yachts are luxurious vessels equipped for deep-sea fishing. They offer comfort and amenities while catering to anglers' needs.

Ice Fishing Shanties

Ice fishing shanties are small, often portable structures used by ice anglers. They provide shelter and protection from the cold while ice fishing.


Dories are small, flat-bottomed boats used for inshore fishing, particularly in regions with strong tidal currents.

Each type of fishing vessel is designed to meet specific fishing requirements, whether for commercial or recreational purposes, and they vary in size, equipment, and features to cater to the unique needs of the fishing activity and the environment in which they operate.


Maintenance Programme

It is a globally accessible Maintenance Programme designed to suit the individual needs of owners, skippers, and those responsible for the maintenance and operation of their fishing boats.

The maintenance programme covers the mechanical, electrical, domestic, deck machinery, and boat safety procedures on your vessel, and automatically resets the programme after maintenance.


Maintenance Plans

Primary Plan covers all the mechanics of a boat from the fuel tank to the propeller and takes priority over all other plans. The Primary Drive Plan is the drive system for your vessel – both these plans include the critical spare parts list. The Secondary Plan covers the auxiliary and domestic systems.


Maintenance Tasks

The tasks are adapted to a vessel’s needs and can be either carried out by the local boatyard or the maintenance crew aboard the vessel. Either way, an owner/skipper is encouraged through our programmes to manage a variety of maintenance tasks, thus understanding better the systems on their boat.


Maintenance Schedules

Maintenance Scheduling is a way to help the planning of maintenance. Yearly monthly, weekly, daily, and even hourly checks form part of the maintenance schedule. We have designed into the programme flexible scheduling which can be readily adapted to a Fishing Boats working programme, and periods alongside.


Fishing Boats - Fire & Safety Equipment Maintenance

Boat Safety procedures and basic fire equipment maintenance practices are essential for the well-being and safety of your boat and crew.

In many countries the authorities are now looking for paperwork showing test certificates and expiry dates for fire and safety equipment, VHF and AIS certification, plus LPG testing. These are systems covered by imardex-marine’s Maintenance Programme.

Fishing Boats - Maintenance

Deck Equipment

Maintenance Programmes and inspection procedures designed by imardex-marine include deck machinery. Lines and warps, gantries, and lifting blocks (emptying bags and cod ends), fish cutting equipment and conveyors, derricks, cranes, wire and box clips for offloading crates to the dockside. Towing points, winches and capstans, rollers, reels, power blocks and hydraulic systems to power these important items of equipment.


Pre-Sea Inspections

Freeing ports and scuppers form part of the pre-sea deck inspection. Engine room and galley inspections are included with a full list of items to check, during these essential pre-sea inspection requirements.


Watertight Doors & Hatches

Watertight doors, hatches and compartments have their own maintenance requirements, including procedures when entering unventilated spaces.


Refrigeration Hydraulics & Auxiliary Engines

Refrigeration, hydraulics, and auxiliary engines are important machinery items on the Maintenance Plan.


Fishing Boats - Emergency Drills & Stops

Emergency Drills include fire practice, man overboard, helicopter rescue and abandoning ship. Practising emergency stops are essential in preventing accidents and loss of nets.

The Modern Diesel Engine its Fuel and the Environment

Modern Diesel Engines

To reduce the increasing threat to the environment and global warming, the harmful emissions of diesel engines have to be reduced. The search for cleaner emissions has resulted in engine manufacturers redesigning fuel delivery systems to the cylinder. Common rail diesel delivery being one system. Injector pressures in the 70’s was around 300 bar (4,351 psi), today pressures are in excess of 2,500 bar (29,000 psi), this higher injection pressure is a key factor in reducing an engine’s untreated emissions. It also improves atomisation by having a better fuel air mixture ratio, meaning that optimum combustion is achieved giving enhanced power output and efficiency.

Fuel & Additives

To reduce harmful emissions from diesel engines, the sulphur content of diesel fuel over the last few years has been reduced from 500 parts per million to 15 ppm. This fuel is now known as ULSD (ultra-low sulphur diesel). This dramatic reduction has resulted in problems for manufactures and operators of diesel engines and diesel fuel distributors. There is a full programme of maintenance and preventative measures to combat diesel bug outlined in the members section, entry by subscription. Engine and Generator Lubricating Oils can be sent for testing, we can advise you on this.

Diesel Engines - Maintenance

We have designed a comprehensive maintenance programme to be followed by owners of marine diesel engines. Requiring only basic skills, this maintenance programme covers all the mechanical work to keep the engine in a seaworthy condition. It does not include tasks where rebuilding is required.

Boat Engines & Drive Systems

Modern boat engines have a higher power to weight ratio and are usually more reliable and cleaner than older engines. Many now have electronic controls to optimize fuel consumption and efficiency. Our maintenance plans reflect this increase in power, by the addition of rescheduled maintenance tasks.
