Very low crew could be a bonus.
Primary armament could be 20/30mm rws, maybe looking toward introducing same as secondary armament on EPV/MRV and eventual roll out to OPV's.

The upper range of MRV's would be more apt, however provision must be included to compensate when payloads are NOT on board. Setanta was a case in point as she was light ship with no bouyage, or anchor chains on board when we took her over. She stopped in head seas and rarely did speeds of 11.5kts. Ferdia was faster but cheerfully would go on fire, in the funnel lagging, when maneuvering heavily.

As for the reasons AM has pointed out, Setanta wouldn't do 11.5 knots on a downhill slope with the wind behind her!Covid 19 is not over ....it's still very real..Hand Hygiene, Social Distancing and Masks.. keep safe

I may have made 2 spelling mistakes typing on a iPhone wrecked tired at nearly 2am on names I'm not used to spelling but I got the speeds right as per Damen and the DF.

Setanta was steam powered. STEAM. Designed to maintain the buoys and lighthouses around the coast before the job could be done by Helicopter. So lots of laying at anchor. Designed to have numerous navigation aids stored in her Hold. I am open to correction, but I don't think her hold held anything during her naval service.
Ferdia was a stern trawler. Only displacing slightly more than the Peacocks with a tiny engine, in comparison.
military.ie up to very recently had people as Officers commanding Naval vessels who were no longer serving in the Naval Service, and we have no such vessel as L.E. James Joyce.For now, everything hangs on implementation of the CoDF report.

Back in 1953, Setanta could probably have achieved her published speed. By the time of her Naval Service she would never have achieved her maximum speed and very modest cruising speed of less than 10kts.
Ferdia again for as often as she went to sea modest cruising speed as opposed to anything like her max.
The RN have a measured mile that ships are tested to their max capability over, this becomes their max published speed although they may never reach it again due to various factors.
Speed in ships is quite variable and economic cruising speed is often a better guide to their capabilities rather a measured dash speed.
The finest example of this relates to aircraft and not ships. In a world of Mach 2 fighters none could sustain it for more than a matter of minutes due to fuel capacity and the only true supersonic aircraft was Concord(e) which actually cruised supersonically for most of its journeys.Last edited by hptmurphy; 16 July 2016, 20:40.Covid 19 is not over ....it's still very real..Hand Hygiene, Social Distancing and Masks.. keep safe
