Fort Myers, Fla - Southwest boating and fishing charters could go broke should oil wash ashore. The looming threat of a slick has customers from across the country calling area charters about their reservations.

"We'd go out of business. If the beaches were covered in oil we'd lose all our people", said Capt. Noah Stewart of Adventures in Paradise in Sanibel Island.

The charter company say it has received dozens of phone calls from customers asking if they will be able hit the high seas.

Many are expressing concerns their travel plans will be ruined by the spill, "businesses like ours are dependent on hotels for business and we would basically have to shut down", the captain added.

Capt. Stewart says it would take several weeks before the first signs of any oil washes ashore.

Governor Crist's emergency declaration extends as far south as Sarasota County, but that could soon change according to officials with the Department of Environmental Protection.
