A LOST nautical treasure has gone display in Pitsea after being hidden in junk for 30 years.

The Motorboat Museum at Wat Tyler Country Park has unveiled the world's first ever solar powered boat after rescuing it from a garage in Warwickshire.

The boat - the Solar Craft I - is said to be "historically priceless", and is acknowledged in the Guinness Book of Motorboating as the first ever vessel to harness the sun's rays.
