RICHMOND, B.C. -- An 25-metre fishing vessel has capsized at a marina on B.C.'s Fraser River, leaving an oily sheen of diesel stretching along the water.

No one was aboard the ship and there are no reports of injuries after the vessel overturned at the Shelter Island Marina in Richmond.

Port Metro Vancouver spokesman John Parker-Jervis says the fuel that escaped is light and likely unrecoverable.

He says a report of the sinking came in just before 8 a.m. Tuesday and the cause isn't yet known.

The Canadian Coast Guard is investigating and the marina has put fuel-absorbent pads around the vessel.

Parker-Jervis says the coast guard would be responsible for recovering the diesel, if any cleanup is possible.
