Well, I don't work in the Industry, but spent my life on it....I mean, I sail almost every day.
I was wondering if I should post or not, unitl I saw Reobert's post.
I too participated in the design, drawing, project of my boat. I did not actually build it with my hands, and had it built by a trusteable known (here) yard, that only makes Custom boats.
She was made for me as I want and everything was decided by me from cratch. The best times I had in my life. In the end of a project like this, where you get 100% satisfaction, and when someone comes along and says, well the door is too tall, I can allways say, not to me...I made it that way...
So in the end I was a happy Customer and a happy "builder".
I envy you for being young and wanting to pursue this industry. Be wise, play your cards well, and you can succeed. All the best, and courage.
