Cutter to sloop
Detaching the jibstay will be of benefit, especially for tacking in light weather. Otherwise a ''tricing-line'' (same as a tack line for an asymetrical spinn.) attached to the genoa clew and pulled forward during a tack will be of benefit - less windage than backwinding the genoa to get it through the slot between the forestay and the jibstay.
Since Most cutters usually balance well on Genoa (or staysail) alone ... another plus when you''re ''lazy''.
In heavy goin'', nothing beats a deep reefed main and a staysl.
Most ''experts'' will argue that a staysail flown under a genoa when on-the-wind is of NO benefit and should be dropped/detached.
