Whats special about our ocean rowing boat?
Shes full carbon and custom built for a 9,000 mile crossing of the Pacific Ocean.
It means she is incredibly strong and very, very light.
Our new one weighs in at 280kg.
620kg less weight over 9,000 miles = a much faster crossing, the trio explained.

Unlike our last row, this will be completely unsupported, so of course there are different challenges.
What if one of us goes overboard?
All three of us have ahistoryof sleepwalking so well all be on high alert.
We might need to install seat belts!
But were more excited than we are scared.
And we get to do that, he added.
Were doing something to change that.
