Anybody out there can send me the dimensions for P27 furling jib/foresail?
The basic boat measurements are here -

Your sail loft will need you to, or they will, measure your boat to confirm things in addition to match any of your particular preferences. The loft will provide you with measuring instructions if they will not be visiting the boat.
There are slight differences between boats because of changes made by prior owners, production changes at the factory and how you have set the rig (rake for example).
