Dufour 42 / Lacoste 42

Launched under the name Lacoste 42 in Paris Boat Show in 1985, she became Dufour 42 in 1988; production then switches workshops of Yachting France with those of Dufour. Designed for Lacoste clothing brand this boat had ambitions to be French response to Nautor's Swan, so she has been designed by Sparkman and Stephens firm (S&S Plan #2462), industrialization was supported by Michel Dufour.

Lacoste 42 is a fast and upscale sailboat, she makes extensive use of teak, the interior is treated with care and hardware is free from criticism. Finally the Lacoste 42 came with towels and sheets branded with green crocodile. Wiser Dufour 42 is nearly a ton heavier than the Lacoste 42 and also drops one of three sets of spreaders.
