The Olea and the Bongo are the same boat. The Olea is the twin keel version.
There is a post on this thread about the big Olea, the 44 (post 101).
They have two new boats, the 44 and the 30. The designer is Pierre Rolland, a French NA specialized in fast and racing boats. He used to be a racer
Both boats have been very well welcomed by the French, specially the ones that like fast boats
