A Canadian legend
A community that supports it

The legendary Disappearing Propeller Motor Boat and its Patented “Device” were both invented in Port Carling, Ontario Canada in 1915. Powered with a 3 hp. inboard marine motor, 3100 boats were produced by four different companies over a 44 year time period. In the ensuing years, it has truly become an icon of classic small motor boats. It is fondly referred to as a Dispro or Dippy.

The Dispro Owners Association mandate is to preserve the Disappearing Propeller Motor Boat and offer fellowship and technical information to all Dispro boat owners and enthusiasts. The association was formed in 1979 and has grown to represent approximately 250 operating Dispro boats and 400 family members throughout North America.
