Spinnaker
David - Are you looking specifcally for the dimmensions the original chutes came in or are you looking to have a chute built? I don't have the original specs, perhaps someone else here does, but if you want to have on built your sail makers can work out the dimmensions from the J measurement and the mast height above the pulpit (sometimes the deck but the sail is easier to work if it clears the pulpit).
