Thieves have stolen a 16-foot boat from its mooring.
It was taken between Sunday 30 August and Sunday 20 September from a mooring in Poole Harbour near to Lake Road, Hamworthy.
The Isla Skiff is green above the water line and pink below, with a cream interior and pine seats. The sails were not onboard.
Police Sergeant Katie Harvey, of Hamworthy Safer Neighbourhood Team, said: “I am appealing to anyone who may know the whereabouts of the boat, or who perhaps witnessed any suspicious activity in the area in recent weeks to contact me.
“I would also ask for people to remain vigilant. Please report anything relating to the sale of a boat matching this description on 101. All calls will be treated in strict confidence.”
