Underwater explorers say they've discovered the shipwreck of a Canadian schooner that sank off Lake Ontario's central New York shore nearly 150 years ago.

Jim Kennard, Roger Pawlowski and Roland Stevens announce Wednesday that they recently found the wreck of the Royal Albert in deep water off Fair Haven, 35 miles northwest of Syracuse. The western New York-based team says the 104-foot vessel was carrying 285 tons of railroad iron that shifted in rough conditions, bursting the ship's seams.

The crew survived the August 1868 sinking by getting into a small boat and making it to shore.

Kennard says the wreck was found in mid-June using side-scan sonar. He says video images taken by a remotely-operated vehicle helped identify the wreck as the Royal Albert, the only two-masted schooner known to have sunk off Fair Haven.
