While it might not be as important if a Spinnaker loses some shape, at least compared to other sails, the sail's material can age quite a bit and then becomes fairly porous, letting a lot of the wind it is supposed to be capturing through.
That sounds like what may be happening in your case. Even if the sail is properly shaped, if the material is so uv-damaged and the cloth has lost its ability to hold air pressure, then it will not be an effective sail.

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.
