Two vessels from the French Navy based in the Breton naval port of Brest, are to make a four-day visit to Dublin Port during the course of St. Patrick's Day festivities. The minehunter CMT Cassiopée (M642) and mine-route survey craft Altaïr (M771) are to arrive tomorrow morning, writes Jehan Ashmore.
The French vessels are to moor alongside Sir John Rogersons Quay, noting they will not be open to the public. Despite that, the naval ships will be accessible to view at close quarters along the city-centre quayside and the addition of easy road access from the north quays using the nearby Samuel Beckett swing-bridge.

CMT Cassiopée is a 'Tripartite' class minehunter built for the navies of France, Belgium and The Netherlands. The class were conceived in the 1970's and built during the following decade. The French built the mine-hunting equipment, the Belgians provided the electronics and the Dutch constructed the propulsion unit.

Displacing 615 tonnes, Cassiopée (see photo) was built by the Direction des Constructions Navales (DCN) shipyard in Lorient and entered service in 1984. The 51.5m minehunter has a crew of 49. Over the years several of the Tripartite class were sold to the navies of Bulgaria, Indonesia, Latvia and Pakistan.

In January 2009 the Cassiopée was joined by the L.E. Emer (P21) in Bantry Bay to commemmorate the 30th anniversary of the Whiddy Island Oil Refinery disaster and the sinking of the French supertanker the Bételgeuse.

Like the Cassiopée the minehunter BRS Altaïr (M771) was also built in 1984 but at the Chantier (Socarenam) shipyard at Boulogne-sur-Mer. At 28m long the craft (photo) is one of the three Antar class which has a 250 tonnes displacement and a crew of 23.

The French Naval call to the capital was to coincide with a visiting task force group from the German Navy. The task force of two frigates and a support ship were due to visit at the weekend but this was cancelled due to humanitarian relief operations off Libya.

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
