Were all the initial problems she had post launch rectified? I.understand there were numerous changes made to Niamh, to rectify issues encountered with Roisin. That said, on either vessel it is almost impossible to remain on the bridge wing in certain winds while in motion. The wind noise is too uncomfortable. Simple aerodynamics I think. The box shaped funnel whacks the wind horribly.For now, everything hangs on implementation of the CoDF report.

Surely we have to be one of the only countries in the world where this argument persists regarding defence?

Virtually a new ship. All of that is consequent on hull areas having to be strengthened or cut out and replaced. When all is done I hope they carry out an Initial Stability Test to see if her start point for Stability is " as built " in the UK.
Since Construction P51 has gained mounts for secondary armament quite high above the CG. For such a squat profile it was an interesting decision.Last edited by na grohmiti; 21 January 2020, 20:48.For now, everything hangs on implementation of the CoDF report.

I know when Deirdre was stripped of all her paint , after her equipment was removed during her mid life refit in 87 it was reckoned she had risen about five inches in the water.Covid 19 is not over ....it's still very real..Hand Hygiene, Social Distancing and Masks.. keep safe

The overall reason is mathematics based on waterplane area (WPA) and Tonnes per centimetre (TPC) loaded on or off in Salt Water or Freshwater. If for example the TPC for a P61 is 7.5 tonnes and she decreased her draft by 12.5cm (5 inches+/-), she would have shed 93.75 tonnes. Our ships carry only a few hundred tonnes of usable weights and mostly make their own FW and have no unpredictable changes in draft, except as you point out after drydocking and paint job.

Why wasn't it tracked by international resources, was there positional data passed to our Government and CG. What were our MPA doing. What were the NS doing with it's Complete Maritime Awareness/Complete Maritime Domain to provide situational awareness to all that need to know. While the errant vessel " ALTA" was floating around, every vessel transiting the SW approaches was in danger. Somebody knew from day one that this vessel was derelict and drifting. Imagine a 4000 passenger vessel steaming into an unlit vessel in rough seas and buried within radar clutter, or a laden tanker from Whitegate doing the same. It is at times like this we must get real and become aware of our geographic position and the responsibilities it brings.

In the last day a ship that was abandoned off Bermuda in 2018 gets washed up on Ballyandreen Strand near Ballycotton. It is only 70/75 metres long and maybe 1000 tonner. It was spotted last year in the Southern area of the North Atlantic on a Latitude with Africa.
