The St. Andrew was a 135′ schooner built in Milan OH in 1857. She was carrying corn from Chicago to Buffalo on her fateful voyage in 1878. The St. Andrew sank at night, June 26, after colliding the the schooner Peshtigo. Both were said to have sank together, side by side, but the Peshtigo has never been located or identified.

Present Condition

The St. Andrew lies in 65 feet of water 11 miles southeast of the bridge, in Lake Huron. She is moored on her bow. She is upright and fairly broken up. She is a great dive for beginning divers or when the west winds make other dive sites suboptimal.  The centerboard, windlass, and major sections of the hull are here, but the deck has fallen to the side, and the hull sides are falling over.

Mooring Buoy Status

This buoy has been removed for 2019 season.  Mooring is just off the bow, using a large, lighted buoy under Coast Guard permit.   Mooring is available from mid-May to September, the moorings make for easier location, safer diving and protect shipwrecks from damage from anchors and hooks.
