Most definately NOT an Oday
The seller was mistaken, go figure. It is definately not an Oday, and as the previous poster have said, more than likely it is a Westerly. A good boat in it's own rites. The twin keels are called bilge keels, so that the boat will sit upright during the extreme tides in the UK and Europe. If this is what you got, the boat is a keeper. Just not an Oday.
