La situation de Tanguy<\/div>\n
\n

Initiatives C\u0153ur glisse toujours en direction du Sud. L’anticyclone des Acores se d\u00e9cale vers le Sud-Ouest. Tanguy ne doit pas c\u00e9der \u00e0 la tentation de couper au plus court en direction de la Guadeloupe car cette trajectoire passe dans le centre de l’anticyclone, et dans cette zone, il n’y a plus de vent.<\/p>\n

Tanguy doit donc pr\u00e9voir sa position par rapport au centre de l’anticyclone pour \u00eatre s\u00fbr de bien le contourner et de rester dans un Aliz\u00e9 bien \u00e9tabli. C’est pour cette raison qu’il passe beaucoup de temps \u00e0 \u00e9tudier la m\u00e9t\u00e9o.<\/p>\n<\/div>\n

L’anticyclone des A\u00e7ores<\/div>\n
\n

le vent circule autour du centre de l’anticyclone dans le sens des aiguilles d’une montre. La ou se trouve Tanguy il vient du nord-ouest. en allant vers la guadeloupe, il va progressivement changer direction pour venir du nord puis du nord-est puis de l’est.<\/p>\n<\/div>\n

\"\"<\/div>\n
Sur la carte, les fl\u00e8ches bleues indiquent la direction du vent<\/span><\/p>\n
<\/div>\n<\/div>\n
Quelles options pour Tanguy ?<\/div>\n
\n

Comme le bateau ne peut pas avancer \u00e0 bonne vitesse avec le vent venant compl\u00e8tement de l’arri\u00e8re, Tanguy doit choisir un c\u00f4t\u00e9 pour mettre un peu d’angle, au moins 40 degr\u00e9s entre l’axe du bateau et la provenance du vent. Il va donc devoir incurver sa trajectoire vers l’ouest pour se rapprocher du centre de l’anticyclone puis tourner vers le sud ouest quand le vent viendra de l’est (car alors le vent viendra de l’arri\u00e8re du bateau, ce qui n’est pas id\u00e9al).<\/p>\n

Tanguy devra doser le moment ou il stoppera sa courbe vers le centre de l’anticyclone pour se diriger vers le sud ouest.<\/p>\n

Plus il se rapprochera du centre, plus l’angle du vent sera favorable mais plus il sera faible. C’est ce qui s’appelle jouer la courbure.<\/p>\n

Plus il s’en \u00e9loignera, moins les angles de vent seront favorables, mais le vent aura plus de force, c’est ce qui s’appelle jouer la pression.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
