Morphology
The compound is compositionally transparent: 'balloon' modifies 'sail' to indicate a sail that is balloon-like (large, light and loose) used to catch the wind and increase speed. This noun+noun modification follows a regular, cross-linguistic pattern, so a B1 learner who knows both constituents can reasonably infer the intended meaning.
Etymology
Balloon sail comes from the sail's look: a large, loose sail that puffs out like a balloon when the wind fills it. That's why the term means 'a light, full sail set to catch wind from behind and make the boat go faster'.
