Title (EN) BODY ACTING AS A FIN OR CENTER BOARD OF A SAILING BOAT
(FR) CORPS SERVANT D"AILERON OU DE DERIVE D"UN BATEAU A VOILE
Abstract: front page image
(EN)The body, used as a fin or center board for a sailing boat, has a horizontal cross section asymmetrical with respect to the vertical longitudinal center plane (18) of the boat, so as to provide a lateral thrust component, and is comprised of at least two portions (14, 16) arranged one behind the other in the headway direction. The front portion (14) has a neutral cross section having the shape of a drop symmetrical to said plane whereas a rear portion (16) arranged on the leeward side of the center plane, has a substantially triangular cross section and gets closer with its anterior side to the front portion of the body so as to complete the drop shape of the latter to obtain an asymmetrical thrust section. The rear portion of the body may be comprised of one of the two retractable center board halves, of which only the one which is on the leeward side is lowered, and there may be a traversing slot (20). The front portion of the body may be shaped as a retractable ballast keel and may be retracted, with the half of the rear portion which is lowered, by means of a cable which is also used to retract only the rear half.
(FR)Le corps, servant d"aileron ou de derive d"un bateau a voile, presente une section transversale horizontale asymetrique par rapport au plan median longitudinal vertical (18) du bateau, de facon a obtenir une composante de poussee laterale, et est constitue d"au moins deux parties (14, 16) disposees l"une derriere l"autre dans le sens de marche. La partie avant (14) a une section transversale neutre en forme de goutte symetrique par rapport audit plan, tandis qu"une partie arriere (16), disposee du cote sous le vent du plan median, presente une section transversale approximativement triangulaire et se rapproche avec son cote anterieur de la partie avant du corps de maniere a completer la section en forme de goutte de cette derniere pour obtenir une section de poussee asymetrique. La partie arriere du corps peut etre constituee d"une des deux moitie de derive relevables, dont seule celle qui est du cote sous le vent est abaissee, et entre ces deux moities peut se trouver une fente (20) traversante. La partie avant du corps peut etre conformee en quille de ballast relevable et etre relevee, avec la moitie de la partie arriere qui est abaisse, a l"aide d"un cable qui sert egalement a relever uniquement la moitie arriere.
