Hi everybudy,after a long literature review,no i has made a desicion to come out with a rigid wing sail which will be applied to my self intelligent yatch.

. I1m goint ot use the catamaran type hull for my project. The reason why i choose rigid wing sail because the sail itself is intelligent enough to follow the wind direction in order to produce drive force. Now,let me refresh back what was my project objective going to be. My objective for my project is to design a self intelligent wind powered boat for recreational purpose. maybe people migh be asking What does it mean with a self intelligent ? It mean that when someone who doesnt know at all how to handle the sailboat (reacreational purpose),but still want to feel the pleasure of sailing.

Nnow,i`m the middle of developing a method or concept to achieve this objective.Maybe i`ll using the sensor method to develope this concept.so, By using this rigid wing sail, and apllying the airfoil theory, i hope that i can make it. So, if any of you here has any idea,homepage or any references..hope can share it with me

.
