Ballasted keelboats can extend that significantly. As pointed out in the June 2015 report, it is important to understand that stability is not the same as seaworthiness.
WebIn order to achieve high stability with a minimum amount of weight and drag, we have developed a keel that is reminiscent of our Whitbread 60 designs. A large lead bulb is supported by a cast steel fin which produces a reliable, durable structure with maximum righting moment. High stability also means less need for a lot of people on the rail.
