Boating NZ - - Feature -

1. No mov­ing parts. One less

thing to op­er­ate or break. 2. If you ground the keels they’re eas­ily – and usu­ally in­ex­pen­sively – re­paired. 3. You can chock the boat more eas­ily on the hard and it is eas­ier to beach in some cir­cum­stances. 4. They cost less to fabri­cate. 5. You get more room mid­ships for ad­di­tional cab­i­netry. 6. The keels add a bit of buoy­ancy. On a 526 the keels are large and mostly hol­low. 7. Daggerboards are typ­i­cally a bit heav­ier. On the 526 each board and trunk weigh about 25kg more than a keel. 8. When not un­der load, poorly-de­signed boards and trunks may rat­tle. Keels don’t rat­tle.

ABOVE The Lag­gon 42 is typ­i­cal of a pro­duc­tion cat equipped with keels. RIGHT A pair of Bal­ance 526 cats was used for the com­par­i­son study. BE­LOW One dis­ad­van­tage of the dag­ger­board – it may rat­tle in its trunk.
