David Summerville and Steve Cockerill had originally planned to make the crossing in September last year, but those plans were scuppered by 50-knot gale force winds and a 12-foot tidal swell, according to Incentive Travel.
But the duo is now planning to try again, with the backing of the Ramada Plaza Southport.
“David and Steve will be covering 115 nautical miles during the challenge," said Ramada Plaza general manager Enda Rylands. "They will set off from my own home town of Dublin and finish in Southport, aiming to raise £50,000 for mental health charity Mind and the John Merricks Sailing Trust."
Summerville, a 53-year-old grandfather of two who runs a boat repair business, said the date of the challenge would again depend on weather and tidal conditions, and that the pair is ready to depart any time from mid-April to mid-September.
It's not the first time that an Irish Sea crossing has been done in a Laser as Tiffany Brien achieved the feat in 2010, sailing single-handedly the 30 miles from Portpatrick in Scotland to Belfast Lough.
But Summerville and Cockerill's ambitious undertaking, at more than three times that distance, would surely get them a place in the record books - provided the weather goes their way!
