The arrival of Thunderchild II into Dun Laoghaire Harbour on Friday gave rise to speculation that a Dublin powerboat record attempt might be on the cards this weekend, given the 80–mph Zero Dark RIB was also berthed at the town marina.

Both vessels have set separate Cork Fastnet Cork speed UIM record times, and it is understood both have an appetite to set further record times off the Irish coast. The latest time was set last month, as Afloat reported here.

On this occasion, though, it transpires the Frank Kowalski skippered Thunderchild was simply on her way home to Cork Harbour from a voyage to Iceland and had merely stopped off for a refuel at Ireland's biggest marina.

However, John Ryan's Zero Dark RIB may yet have her eye on some UIM record times while based in the capital's waters.

The high-speed RIB has been out Dublin Bay clocking up some impressive speeds over the past two weekends.

More news on any record attempt as we have it.

John Ryan's planned arrival into Dublin Bay this evening by high speed RIB was scrubbed shortly after his UIM record bid started at Cork Harbour this morning.

Ryan told Afloat "We lost the middle engine, we'll be a no show today".

It's a frustrating scenario for the record-breaker given the current favourable weather forecasts and flat seas.

As Afloat reported earlier, the Royal Cork skipper was due to depart Cork Harbour at 11 am in the 85-mph RIB.

As regular Afloat readers will know, Ryan broke his own existing Cork Fastnet Cork speed record in a time of 1 hour, 47 minutes and 7 seconds (Subject to ratification by UIM) last week as reported here.

The Zerodark team are expected to set a new date for the Cork-Dublin run and other Irish powerboat record attempts too.
