- 1,800 copies since 1976
- From 5,000 euros for a first generation keelboat - before 1984. 35,500 euros new.
This one-design dedicated to racing remains versatile in all conditions and at all speeds. And it is always a pleasure for its helmsman - exemplary smoothness and precision at the helm - and his crew! But beware, there is Surprise and Surprise. The one that registers is the keelboat, available in several versions. Alongside there are numerous versions more oriented towards cruising: ballasted dinghy, pivoting keel or twin keel.

The diagnosis of Bateaux.com
Tough but sometimes harshly treated - especially by the clubs - the Surprise first version requires a lot of elbow grease to get back to its former glory, especially indoors. On the first models, check the anchoring of the chainplate.
"The Surprise is a marine sailboat, soft at the helm and well balanced, it is a boat of unfailing solidity".
Pierre Simon, base chief of the Cercle de Voile d'Arcachon.

But what is he missing?
A mobile keel to facilitate road transport
The equivalent today?
The J 70 is probably the one-design with the closest spirit: the simpler the better!
