Split list of curves with plane

Hi everybody, I need to split a bunch of curves, that are sections of a hull, with a plane that I created at the maximum beam, and a longitudinal plane. At the end I need to be possible to select indipendently one of the four groups of curves. I’d be greatfull for any help, thanks.

PS: the file I update is a bit confusing, I put the curves and the planes to the extrem right

You need Pufferfish (Point surface side) for this:
