Asymmetrical sail cut

[Charlie98117]

I am looking at a used North Sails asymmetrical with a leech dimension that seems much shorter than what I usually see. I'm wondering if that is a special cut designed for a specific purpose.
The dimensions are 48.95' on luff and 37.5' leech and 24.1 foot.

I'm really looking for something that will give me deeper downwind angles and I'm not sure if that favors a longer or shorter leech.

While it's impossible to tell solely from the edge dimensions, that shape would typically indicate a reaching sail, and not a running sail.

The higher clew would allow nice sail shape when it was pulled back on a reach. If you see code 0 sails (extreme reachers) they have high clews, indicated by the shorter leech.

The REAL check would be the fullness of the cut, and how much rounding there was in the luff. Running sails will be MUCH fuller in shape, and have a curved luff designed to fill and rotate the sail out and in front of the boat on deep wind angles.

Thanks Jackdaw. Your response is exactly what I was thinking.

The current owner bought the sail used from our local North Sails store so there was a contact person in the correspondence I was sent. I reached out to the sales person saying I was concerned about the cut being a reacher rather than a runner and got the following response this morning: That sail was built for a J 105 that has a sprit, so it is more of a low aspect sail design, but still a runner design. A new design for your boat would have a little less difference between them. Sounds like it is not ideal but might be OK for a low budget deal.
