5105 “Een bulb in het midden is eigenlijk een onding”



“Een bulb in het midden is eigenlijk een onding”, by Peter van Oossanen, Published in “Zeilen”, No. 12, December 1999, pp. 38-48 (ID No. 5105)

 This article (in Dutch) describes the advantages of dividing the side force development, and the positioning of lead ballast in the form of a bulb attached to the bottom of the keel fin, on an International America’s Cup Class (IACC) yacht into two parts – one located forwards on the hull and the other aft on the hull – rather than in a single keel fin-bulb configuration in the middle of the  hull.
