Vessel History

Rebuilds/Renames  Rebuilt 1851; Renamed Mayflower 1854 then Comet in 1860
  Built as a twin paddle wheel steamer in 1848 with two walking beam steam engines.  It sank from a boiler explosion in 1851 killing eight persons.  The hull was salvaged and rebuilt then renamed Mayflower in 1854 then back to Comet in 1860. On its first voyage of the season May 1861 in strong winds it collided with the schooner Exchange.  Both vessels tried to stay close but the Exchange drifted away in the wind.  All passengers and crew abandoned ship in the lifeboats.  Two crew were killed in the process.  The rest landed on Simcoe Island.
Disposition Sunk in a collision with the schooner Exchange off Simcoe Island May 15, 1861 killing two crew.
