Former SAS soldier Tom McClean has spent 100,000 pounds and 2 decades building his 20-metre boat in the shape of a whale.

Moby the boat is set to take her 73-year-old creator on a journey from Loch Nevis in Scotland to London and then New York, USA, which is a 5,600-kilometre adventure.

When asked why, the man says, ¡®Why not?¡¯ He does things instead of watching television, and he aims to get environmental companies to be involved so he can help the planet as well.

Difficult words: former (-ex), SAS (Special Air Service), loch (the Scottish word for ¡®lake¡¯), aim(have a goal for something).
