Police have launched an appeal for witnesses following the theft of a £30,000 sports boat from the side of the road opposite a slipway off Hamble Lane, Hamble.
The theft happened between 3.20pm and 4.45pm on August 31, 2010.
The owner, a Worcestershire man, had positioned the boat across from the slipway in Ensign Way while he waited for the tide to come in.
He left the red and white Regal ‘Halo’ speedboat for just under an hour and a half and when he returned to the site, the powerboat was gone. He did not see or hear anything suspicious within that time.
Sergeant Bob Chambers from the Force Marine Unit said: “This is an uncommon theft but one that must have been witnessed by someone.
“This is a very expensive craft which was taken within a small window of time. I’d ask anyone in the Hamble area on that day to cast their minds back and think whether they may have seen something suspicious.”
In February a Rib Craft was stolen from Botley Mills and was then found abandoned at Warsash.
Police are appealing for anyone who may have seen the boat at around that time, either on the slipway or being towed, to contact Acting Sergeant Bob Chambers on 101.
Alternatively contact the charity Crimestoppers line where information can be left anonymously.
