Capri 22 are nice boats! enjoy.
not sure how the headsail gets in between the forward lowers to hang up in here. it must be flapping a lot mid tack. are you holding the old leeward sheet until the headsail is ready to tack? try backwind'ing the headsail longer, until it's ready to come across.
also try lowering the car on the mast track to deck level when not in use.
or remove the car if you don't plan to use a spin or whisker pole.
