The European Commission is seeking proposals to develop a fishing vessel equipped with alternative propulsion technologies and improved energy performance.

The “demonstrator” vessel should foster energy transition in the fisheries sector, and has a budget of 2.2 million euro, drawn from EU pilot project funds.

The Commission lists the expected impacts as:

To develop and demonstrate viable solutions for fishing vessels which improve the energy performance, including reducing greenhouse gas (GHG) emissions and costs;

To increase knowledge on the challenges, benefits and impacts (including economic, environmental and in terms of health and safety of fishers) of different technologies aimed to improve the energy and emissions performance of fishing vessels;

To strengthen understanding of the potential to adapt existing technologies to the fishing sector;

To raise awareness of and broaden the possibilities offered to fishers to become more energy efficient and initiate the energy transition of fishing vessels.

It says long term expected impacts include:

  • Improving the resilience and economic viability of the EU fishing fleet;
  • Improving understanding of technical, social, legal, regulatory and policy barriers to energy transition in fisheries;
  • Reduced fuel consumption and GHG emissions from fishing vessels and improved energy efficiency in their range of activities;
  • Accelerating the adoption of new technologies in the fisheries to foster energy transition;
  • Improving the business environment and raising awareness among investors.

The closing date for proposals is June 11th, and more details are here.

New DIY Copper Protection

Marine Technology Ltd, owner of the CuNiGuard antifouling system, has developed a new, single application copper antifouling product which can be owner applied. Copper-Tek uses a specialised copper which has been extensively tested to create a coating, providing, say the manufacturers many years of antifouling protection from the single application.


During mixing, each litre of Copper-Tek resin is impregnated with 2 kilograms of ultra fine copper powder, the maximum allowed by law. Marine Technology is confident that there is no stronger copper based antifouling system currently available on the market. Following the company's application instructions, a minimum of 200 microns of Copper-Tek is applied, typically the surface will erode at a rate of 5 microns per year. Prior to launch the cured the Copper-Tek surface is lightly burnished with a fine wet and dry paper to allow the copper to activate on contact with the water.

Further burnishing is not anticipated for several years. If ashore for an extended period, a light rub with an abrading pad or fine wet and dry is all that is necessary to reactivate the coating and continue fouling free cruising. Once immersed, the special copper reacts with seawater to form a thin slippery surface covering of cuprous oxide, resistant to all common fouling such as weed, barnacles and other marine growth, but non toxic to the environment. A minimum of 10 years protection should be expected from a properly applied Copper-Tek system.

Using Copper-Tek eliminates the annual labour and high costs of lifting out, preparation and reapplication of antifouling coatings. Previously, high volume copper based products have been prohibitively expensive but Copper-Tek can now offer a DIY option at very reasonable cost. Unlike ordinary antifouling paint, the active Copper-Tek ingredients are hosted by an epoxy resin base which also provides a degree of protection against osmosis in GRP hulls. The treated boat can therefore remain in the water for the owners enjoyment for longer periods.

Copper-Tek is fully approved and licensed for professional and owner application in UK, HSE No 9240 and available from Marine Technology Ltd +44

About Electric outboard engines

The direct-drive component in electric outboard engines means that the electric motors are incredibly efficient compared to conventional marine combustion motors, operating with considerably higher torque whilst using less power.

Without any need for gears, cooling systems and moving parts the motors are maintenance free, highly efficient and economic to run.

As a result, electric boat engines are becoming more popular on Irish waters as the world transitions from fossil fuels to green energy.

To date, popular electric engine sizes have been trolling engines typically used by fishermen on lakes.

These marine engines are available in models that can be used in fresh water and sea water, for your boat or kayak.

Electric motors are Ideal for fishermen because they are quiet and create little in the way of disturbance 

Popular electric trolling models range from 30lb thrust to 55lb thrust in a range of shaft lengths.

But use is becoming broader now in 2021 and electric outboard engines are being used on small runabouts and RIBS where electric outboard engine sizes are getting bigger.

Outboard electric engines are economical and environmentally friendly. Battery technology is also improving at a rapid rate meaning they are becoming smaller and lighter and run for longer.

Built in hydro-generation provides alternative recharging options whilst under sail are also options meaning the electric outboard now has a home on the stern on small yachts and dayboats too.

As far back as 2014, Torqeedo owner Jack O'Keefe from Cork Harbour told Afloat readers of his sailing adventures in a Drascombe Coaster dinghy and how after swapping from a petrol version the rewards from his new electric outboard engine are less noise, no smells, more stowage, better sailing performance and a motor that can be started by a small child. But it's still not silent, there's a whine he says here 

Popular brands in Ireland are Torqeedo, ePropulsion, Pulsar and Minn Kota but there are more arriving all the time as the technology advances
