Code sail / gennaker
The sails between a genoa and a spinnaker, named by their mid-girth.

Between the flat genoa and the ballooning spinnaker sits a family of reaching sails, and the naming is refreshingly literal: the number is the mid-girth.
A Code 0 is nearly flat — effectively a huge, light, furling genoa for close reaching in light air. A Code 50 or 60 is a reaching sail with some real shape. A Code 70 is well on its way to being a spinnaker.
Gennaker is the everyday word for the cruising end of this family: an asymmetric flown from a furler or snuffer, around 70% mid-girth. Hoist, unroll, go — no pole, no drama.
The words are loose across the industry and everyone uses them slightly differently. The mid-girth number isn't loose, which is why we lead with it. See our downwind sails.
