Track Length and Switch
Height Considerations
Switch height is determined by the number
of cars required for system and the length
of the storage track.
Note: Cars will not pass each other if
top of car is higher than “A” distance.
See chart below.
Make sure track is longer than sail luff to
allow for stretch as sail ages. Track must
not block halyard exit.
