Just a question, would it be difficult to make your own snuffer ring/chute mouth out of fibreglass? can the dimensions be obtained from anywhere? or would i be better off getting one made professionally? Also whats the diameter needed on the sock, i know from greg goodall who made my spinnaker, it needs to be around 1.9 metres long for my spinnaker, but what kind of radius/diameter, i know theres a trade off, smaller bag=less windage but tighter spinnaker: harder to raise/retreave; larger bag=more windage, but easier flowing spinnaker.

Thank you.
Michael.
