ST. AUGUSTINE, Fla. -

Two boats struck the Bridge of Lions late Wednesday morning after breaking loose from anchors in the St. Augustine bayfront because of heavy winds.

A trimaran sailboat was jammed under the bridge, half-submerged, and a houseboat also struck the bridge.

Each boat had two anchors, and all broke loose. A third boat also broke loose from its anchors, but it didn't hit the bridge and was not damaged.

No one appeared to be on the sailboat.

One of the cables from the sailboat's mast was stuck on part of the bridge, keeping the boat from moving.

About 20 gallons of diesel fuel created a slick that stretched about a mile long down south of the Intracoastal Waterway. The St. Augustine Fire Department was using boom, a material used to help stop a spill from spreading.

"Essentially what we're doing is surrounding the vessel with a material that floats and absorbs the lighter, leaking hydrocarbons," said Capt. Carlos Aviles, of the Fire Department. "The weather's working against us, but we're doing what we can with what we've got."
