Designed by Laurent Giles after the success of the Centaur the 21' Warwick and the Jouster were aimed at two very different markets. The Jouster for racing and the Warwick for cruising. The Warwick was a much heavier design (and pricier) with bilge keels, full accomodation and providing you weren't taller than 5'10", headroom. Whilst not a fast as the Jouster, because of her long waterline length and tall rig she had a good turn of speed. The Warwick was superceeded in 1977 by the W21.
