An 10-foot unmanned robotic yacht was launched off the Irish coast as part of a trans-Atlantic challenge, although it is not expected to complete it.
Pinta was built by scientists at Aberystwyth University, who have carried out sea trials and taken part in competitions since 2006. But this is the first time their boat has attempted the Microtransat Challenge ocean crossing.
Aberystwyth is the only team competing in this year's challenge.
"I don't think Pinta will succeed because there are some horrible weather conditions out there. There are 35- to 40-knot winds and the remnants of a hurricane," says Mark Neal of Aberystwyth University. "It will probably capsize. It is waterproof, but it won't survive the continual flipping over."
