Gibert Marine
Gib'Sea 302
Deep draft

The Gib'Sea 302 is the perfect example of cruising-racing monohull, she made her mark racing (winner of the Spi Ouest France in 1993) and cruising including a massive hit with renter. The wide hull is powerful but its large wetted surface penalizes the Gib'Sea 302 in light air.

The width also allows spacious interior, we can easily seat at six around the saloon table. The kitchen is compact but well equipped. The cooler changes sides and ends up under the chart table, to allow more space in the kitchen.

The Gib'Sea 302 was available in three versions: shoal draft, deep draft and centerboard. The hull was used for Dufour 304 Trophy.
