Duke-Class Frigate Docks In Dublin
The Royal Navy's HMS Portland (F79) a 4,900 tonnes displacement Type 23 Duke –class frigate built as the last of fifteen such vessels a decade ago is on a weekend visit to Dublin Port, writes Jehan Ashmore.
Launched in 1999 at the shipyard of the then Marconi Marine at Scotstown on the Clyde, she then entered service two year later. During her contractor's sea trials she achieved a top speed of 30.8 knots and claims this as a record across the entire class.

She measures 133m (436ft) long and on a beam of 16.1m (52.9ft) and has a crew compliment of 185 in total. An array of highly sophisticated arnament is packed on board in addition she can convey a Lynx helicopter. Propulsion is derived from a combined use of diesel and gas (CODLAG) .To read more about the penultimate Type 23 class and her sisters click HERE

We've got a favour to ask

More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven’t put up a paywall because we want to keep our marine journalism open.

Afloat.ie is Ireland's only full–time marine journalism team and it takes time, money and hard work to produce our content.

So you can see why we need to ask for your help.

If everyone chipped in, we can enhance our coverage and our future would be more secure. You can help us through a small donation. Thank you.
