The Jeanneau Brin de Folie, also called the Folie Douce, is a French sailboat that was designed by Jean Marie Finot and Philippe Harlé as a cruiser and first built in 1970.^{[1][2][3][4][5][6][7][8][9][10][11][12][13]}

The design was built by Jeanneau in France, from 1970 until 1980, with 820 boats completed. The design was originally marketed by the manufacturer as the Folie Douce (English: Tender Madness), but in 1975, halfway through the ten-year production run, the name was changed to Brin de Folie (English: Touch of Madness).^{[1][2][3][4][14][15][16]}

The Brin de Folie is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, with a deck-stepped mast, one set of straight spreaders and aluminum spars with stainless steel wire rigging. The hull has a raked stem; a raised counter, reverse transom; a skeg-mounted rudder controlled by a tiller and a fixed fin keel. It displaces 6,614 lb (3,000 kg) and carries 2,425 lb (1,100 kg) of cast iron ballast.^{[1][2][3][4][5][6]}

The boat has a draft of 5.41 ft (1.65 m) with the standard keel and 4.83 ft (1.47 m) with the optional shoal draft keel.^{[1][2][3][4][5][6]}

The boat is optionally factory fitted with a inboard diesel engine of 10 hp (7 kW) or may use a small 10 hp (7 kW) outboard motor for docking and maneuvering.^[5][6]

The design has sleeping accommodation for six people, with a double "V"-berth in the bow cabin, two straight settee in the main cabin and an aft cabin with a single berth on the starboard side. The galley is located on the port side just forward of the companionway ladder. The galley is equipped with a two-burner stove, an ice box and a sink. A navigation station is opposite the galley, on the starboard side. The head is located just aft of the bow cabin. The fresh water tank has a capacity of 24 U.S. gallons (91 L; 20 imp gal). Cabin headroom is 73 in (185 cm) in the main cabin and 61 in (155 cm).^{[1][2][3][4][5][6]}
