About the COOPER 353

The Cooper 353 is a Canadian-built cruising sloop designed by Stan Huntingford and constructed by Cooper Yachts Ltd. in 1979. While the exact total production volume is unknown, this model represents a specific era of Canadian boatbuilding with a distinct fin-keel, masthead sloop configuration.
- Best for:

- Bluewater capability:
