Yes, fiberglassing the rudder will add some thickness..but you will be shaping the plywood to an airfoil shape (in an ideal case), and that will remove some of the thickness of the plywood... so starting at 1.5" thick would probably be better than starting off 1/4" shy of it.

I am shooting for 1 1/2" based on my old rudder and the width of the band that bolts on the pintles. Will the glassing add any noticable width to the finished rudder? thanks for your help and advice.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
