As strollers take in the fresh conditions along Dun Laoghaire Harbour's East Pier today they will see the state's first purpose built oceanographic research vessel RV Celtic Voyager moored alongside at the jetty, writes Jehan Ashmore.
With her distinctive 31m green-painted hull, the 340 gross registerd tonnes (grt) vessel built by the Dutch Damen Shipyard in 1997, was commissioned for the Marine Institute, whose headquarters are based outside Galway city at Oranmore.

RV Celtic Voyager is an inshore RV and she can accommodate 6 - 8 scientists with a maximum endurance of 14 days. According to her intensive survey schedule she is currently conducting hydography work for this month entirely. To read her complete survey programme click HERE.

In 2002 she was joined by a second though considerably larger vessel the 65m RV Celtic Explorer, which is six times larger than her fleetmate in terms of tonnage, which is 2,425grt. Apart from all the scientific and deck machinery she can also handle seven 20-foot containerised laboratories.She has accommodates for 35 personnel, including 19-21 scientists and has an endurance window of 30 days.

The vessel was also built by the same Dutch shipyard and both are owned by the Marine Institute. Ship management of the Galway based pair is provided by P&O Maritime Services (Ireland) Ltd.

In addition the ROV Holland I a deepwater Remotely Operated Vehicle is operated on board the RV Celtic Explorer. The ROV is named after John Phillip Holland from Liscannor, Co. Clare who was an early inventor and builder of submarines. For more information about the ROV which forms as part of tonight's 'Sea2Sky' event in Salthill, Galway, as previously reported on Afloat.ie click HERE.

Today is European Researchers Night, where the ROV will be on display in Galway

During the weekend call of L.E. Eithne to Galway Harbour, the Naval Service flagship shared the mid-west port with a Spanish oceanographic research vessel (RV) and a cargoship,writes Jehan Ashmore.
The port consists of a single basin named the Dún Aengus Dock where the Vigo registered RV Vizconde de Eza (2000/1,401grt) was berthed. The 53m vessel is run by the 'Secrataria General del Mer' (MARM) which is on an assignment to asses the abundance, estimation and distribution patterns of demersal-benthic species in the Porcupine Abyssal Plain. The port is of also the homeport to the Marine Institute RV vessels and their headquarters based in nearby Oranmore.

Also sharing the basin but located closer to the dock gates was Arklow Shipping Ltd's Dutch registered dry-cargo vessel Arklow Surf (2000/2,316grt). The dock is capable of handling more vessels simultaneously and of course used as a host-port of the high-profile Volvo Ocean Race which is due to return next year.

Galway and neighbouring Limerick City with its Ted Russell Dock, are the only dock-gate accessed ports on the island of Ireland. In the case of Galway there is an exception as freight operations are also available from an outer pier on the seaward side of Dún Aengus Dock though only for domestic purposes. From this pier the dedicated Aran Islands freight service is operated by Lasta Mara TEO's Blath na Mara (1983/330grt). As for Limerick, vessels can also berth outside the dock but they tend to be small port-work related craft that use the outer berth on the Shannon Estuary.

The Galway Harbour Company in recent years have proposed plans for a new outer port, to be built in four stages with a completion date set for 2017. This would enable larger deeper drafted vessels such as tankers and cruiseships to dock in the new port. In the meantime cruiseships anchor off Mutton Island. In addition a freight rail-link, berthing for an inshore fishing fleet and a 216 berth marina are proposed.

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
