1. As the study shows, boarded cats point higher with less side-slip. On keeled pro­duc­tion cats you can “stick them up into the wind” but they tend to crab hor­ri­bly when pinched – you must crack off con­sid­er­ably to re­duce lee­way and sus­tain mo­men­tum. 2. Typ­i­cally, the draft on keel cats is deeper than on dag­ger-board cats. Our 526 keel ver­sion draws about 300mm more than the dag­ger-board ver­sion. Some cats carry very stubby keels to sus­tain shal­lower draft, but the shal­lower the keel the poorer the close-hauled per­for­mance. 3. Off-the-wind with the boards raised 75 per­cent there is less drag and the boat steers and sails faster and more play­fully. 4. As the study shows the dag­ger-board cat is a bit faster and makes less lee­way on nearly all points of sail in the ma­jor­ity of wind con­di­tions. 5. An equally ef­fi­cient set of keels has al­most four times more wet­ted sur­face than dag­ger-boards, as is the case on our 526 keels. 6. Set prop­erly, dag­ger-boards can as­sist in prevent­ing a cat from a ‘trip­ping cap­size’ in very high winds with large, break­ing cross seas. Both boards can be fully raised, or only the lee­ward board raised, so the boat can sideslip eas­ily. 7. Dag­ger-boarded cats tend to have a slightly higher re­sale value because few are masspro­duced. A buyer want­ing boards tends to fo­cus on cats that have them.
