If you're near Largs at the end of February, there's an opportunity to see this fascinating account of the construction and use of an electric lobster boat.
He has an entertaining channel on Facebook. The vids are worth a watch. He has been using the all electric boat for a wee while now, very successfully.
Our mooring is in the same village as the “It’ll never work” boat and we know Hans. I can guarantee the evening will be hilarious - thoroughly recommend going along.
