No they are not, they just need lots of stuff added because they are tensioned so much . on the water on a slip of foam you need constant supply of power.

you wont need to unpick the white bit as most of it wiil get cut away.
next job is to fill in that hole in the pocket then stretch it out nice and tight. you should find that the leading edge is really straight and the trailing edge has all the curves I would recommend as a first sail you rebuild witha straight,untapered pocket. Put all the cams in the bin and never use them again.
Fit the sail by the leech as I said beforeto your cl5 sail. then I will do a drawing for you.
Remember that reverse of the luff curve at the head of the sail...... That is how the sailmaker stops the head from falling away so draw a template of the top 500mm of the sail at least
