Asymetrical Spinnaker Dimensions - Young Son 35

[Lilrascals]

Does anyone know the dimensions for an asymmetrical spinnaker for a Young son 35? ( same as Tayana 37 or Union 36). Any info on spinnakers of any type would be helpful. Thanks. We're in the market for a good used sail.

The luff should be tight when fully hoisted and tacked down hard. The breadth will be about 150-185% of the I dimension (stem to mast) or in otherwords well aft the shrouds but not at the cockpit.
