Two thirds of the earths surface is covered by water - Our carbon fibre power catamarans can safely cover all of it
Offshore Wind Energy is expanding globally requiring a continuing number of catamaran workboats. TMD Workboats intends to be a major player in this industry with our four FUEL EFFICIENT light weight carbon fibre workboat models
Welcome to Trawlercat Marine Designs & Workboats
Following the 2007/2008 global economic downturn that crippled the recreational boat market Trawlercat Marine Designs (TMD) focussed on designing catamarans for workboat markets.
Our latest series of designs are High Speed Long Range carbon fibre Navy Pocket Patrol Boatsdesigned specifically as simple to operate and maintain low cost patrol boats. These boats are well suited for developing nations with major maritime criminal activities occurring regularly in their harbours and elsewhere within their territorial waters. These criminal activities include hijacking ships for ransom, or stealing their oil cargo, or robbing the crew of money and possessions. Locating and capturing these pirates will require a lot of small high speed Patrol Boats to cover large coastal areas where most of these pirate activities take place. This is where our 45 knot Pocket Patrol Boats will excel.
Our second series of designs are directed at the global offshore wind farm industry with our range of four carbon fibre crew transfer service catamarans. The 20m model is excellent for near shore work with the 26m, 30m and 35m models capable of working further offshore due to their twin foil system and 4 engine twin water jet or controllable pitch propellers configuration.
Carbon fibre is ten times stronger than aluminium and less than half its weight and once we discovered how to build them competitively against our aluminium competitors the decision to use carbon fibre was a 'no brainer'.
Aluminium is a slow build process with every join having to be hand welded taking months of work and a lot of man hours. Fiberglass was a possibility but after further research we made the decision to design all our workboats to use carbon fibre and use the “epoxy resin vacuum infusion carbon fibre and Kevlar foam sandwich method”. This will result in a superior and super strong lightweight catamaran structure that will provide double the working life of aluminium catamarans. Our new range of carbon fibre workboat catamarans we call Carbon-Cats.
We have designs for the commercial fishing industry a SCUBA Dive cat and a Party Excursion cat and we did a special project for an all-electric replica of a Mississippi River Boat catamaran that we would love to build for someone.
And of course all our recreational models are still available for custom building and information for all of these catamarans can be found on this web site.
Trawlercat Marine Designs made a strategic decision to once again become our own boat builder and to this end we are actively seeking a Global Boat Builder Business Partner or a Joint Venture Investor Business Partner.

Offshore wind is a major renewable energy industry that is expanding globally and URGENTLY NEEDS carbon fibre catamarans to help bring down the high cost per kilowatt of offshore wind energy.
Carbon-Cat OWF Crew Transfer Service catamarans are available in 20m, 26m, 30m and 35m sizes and are half the weight of similar size aluminium catamarans. They use smaller engines that weigh less use less fuel and still outperform similar size aluminium catamarans. Lower weight and innovative features results in a lower fuel burn and longer range and will reduce the vessel Owner’s annual fuel cost by 50% compared to a similar size aluminium catamaran.
WHO WOULDN’T WANT TO SAVE 50% OFF THEIR ANNUAL WORKBOAT FUEL COST?
TMD’s antipiracy Pocket Patrol Boat catamarans have a 45 knot top speed, a 4,000 nautical mile range and are capable of patrolling open ocean waters along major shipping routes of the West Coast of Africa, Gulf of Guinea, Gulf of Aden, Gulf of Oman, the West Coast of India, the East Coast of Africa and the Mozambique Channel.
They can patrol “Hot spots” in South East Asia, South America and the Caribbean and out to the edge of any country’s territorial waters on “search and rescue” missions, searching for pirates, drug smugglers, illegal immigrants, polluting ships and foreign trawlers poaching billions of dollars’ worth of fish every year.
TMD’s antipiracy Pocket Patrol Boats are half the size of many Navy Patrol Boats. They can best be described as “Littoral Riverine Pocket Patrol Boats” as their shallow draft and water jets allow them to search out drug smugglers, pirates and pirate boats along the shoreline, on the beaches, in shallow bays and inlets and up rivers. Carbon-Cats are also designed to nose up to a beach, lower a bow boarding ramp and send armed marines ashore on foot or in side-by-side diesel powered ATVs to explore further in areas that may be inaccessible from the land.

Carbon fibre is less than a quarter of the weight of steel and Carbon-Cat Multi-Mission High Speed Pocket Patrol Boats, (HSPPB) are more practical and far less expensive to operate than large metal Navy Patrol Boats. The HSPPBs are not meant to be warships fighting other warships at sea and they don’t carry missiles or cannons.
The HSPPBs purpose is to patrol a countries territorial waters and apprehend private or commercial vessels that have broken the law. Most of the offending vessels will only have a few hand held weapons not heavy artillery and they’re not likely to show their weapons when they see a Patrol Boat bearing down on them at full speed with a dozen machine guns pointed at them.
The 20m to 35m High Speed Pocket Patrol Boats are very inexpensive to purchase and to operate and should at least be operational in every country where they have fish poaching problems. These vessels will soon pay for themselves from the revenue brought in by fishermen exporting their catch.
Carbon fibreisfive times stronger than steel, ten times stronger than aluminium and less than half the weight of aluminium. Its strength, durability and double the life of aluminium catamarans will be a huge bonus for Workboat Companies saving them millions of dollars throughout a vessels working life. In the hard working workboat industry strength and durability are key to a boat being able to take a lot of punishment and not have to be hauled out of service on a regular basis to weld cracks in the aluminium. Carbon fibre does not crack, rust or corrode, it requires far less maintenance than steel or aluminium and unlike aluminium paint stays on it.
Carbon fibre is relative new to the boating industry due to its very high cost. The price has come down over the last four years and is expected to fall even further as new carbon fibre manufacturers start up and different industries start using it in great quantities. There is no doubt carbon fibre is an economical force to be dealt with as it comes to be used in more and more products including everything from high rise buildings to the roads and bridges we will drive our carbon fibre cars on.
TMD has found innovative ways to absorb the high cost of carbon fibre allowing us to offer our clients a competitive price against aluminium cats. Building Carbon-Cats in as many production moulds as practical is much faster and will save many thousands of man hours compared to hand welding aluminium cats. Using proven production techniques to further speed up the assembly and fit out of a Carbon-Cat will save even more man hours. Building boats faster is smarter as time saved does not have to be paid for and the more boats completed in the shortest possible time the more the operational overheads are amortized.
With a large enough facility our schedule calls for a 60 work day build time for a 20m OWF Crew catamaran and with a continuous backlog of six boats on the shop floor we can roll a Carbon-Cat out the door every 21 work days and provide seventeen 20m Carbon-Cats a year. Amortising fixed overheads over 17 boats a year brings down our cost per vessel considerably compared to amortising fixed overheads over just one or two aluminium boats a year.
Carbon-Cats 50% lower fuel consumption longer working life and lower maintenance costs are something aluminium cats cannot match.These cost savings are ongoing year after year and service operators who do not purchase Carbon-Cats will be passing up a serious amount of profit. Eventually they will not be able to compete against service operators who make the change to Carbon-Cats as they will bid lower on new contracts and win the contracts. Lower service costs to the OWF Owners will help to bring down the cost per kilowatt of offshore wind energy.
One other very important advantage of a Carbon-Cat is due to its carbon fibre foam sandwich construction. The closed cell foam panels are positively buoyant and along with designed in water tight void areas Carbon-Cats are totally.....
