#Lifeboats - The video above shows off a prototype of the RNLI's new lifeboat class, the Shannon, as it undergoes sea trials to determine how it handles the rough weather all too common to the seas around the UK and Ireland.

As previously reported on Afloat.ie, Irish naval architect Peter Eyre has been instrumental in the new lifeboat design, which is nearly 50% faster than the vessels currently in service.

It's also the second RNLI boat to be designed by an Irishman, after the Atlantic 21 developed in the 1970s by Cork-born Rear Admiral Desmond Hoare at the Atlantic College in Wales.

In other RNLI news, tributes were paid in the Isle of Man this week to the founder of the lifeboat institution in an annual ceremony on the Irish Sea island.

As BBC News reports, Sir William Hillary launched an appeal in 1824 that let to the formation of the RNLI, and he went on to serve as a member of the lifeboat crew at Douglas.

#INLAND WATERWAYS - Waterways Ireland has taken delivery of its third tug boat from Mooney Boats of Killybegs.

Designed by Marine Design International, the Inish Fendra is an 11.2-metre LOA steel-built tug which has been specifically tailored for operation on the Shannon-Erne waterway system.

Its design bears many similarities to the Inis Muillin, which was delivered by Mooney Boats in 2010.

The new tug, Inisfendra built by Mooney Boats of Donegal

According to Maritime Journal, the design process "involved significant input from the vessel operators and managers combined with the latest technology and ideas from the designers and builders to improve on efficiency" and safety.

A key feature of the Inish Fendra is its 3,500-litre ballast tank and pumping system, which is operated by the push of a button and can reduce the vessel's air draft by 0.2m.

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
