5101 “De juiste kiel”

“De juiste kiel”, by Peter van Oossanen, Published in “Waterkampioen”, Part 1 in June  and Part 2 in July, 1996 (ID No. 5101).

After an explanation of the function and working principles of keels in general, this paper (in Dutch) reviews the many types of keels that have been devised for sailing yachts and rates them in a relative sense with respect to the contribution they provide to righting moment (stability), to side force (in counteracting leeway), to directional stability (as in their effect on steering behaviour), with respect to the drag they cause, with respect to the draught (span) they require, and with respect to their cost.
