Q&A
WHY DO I WANT A SWITCH 
BATTCAR SYSTEM? 
A Switch Battcar system cuts stack 
height in half, so putting on a sail 
cover or connecting/disconnecting 
your halyard is a much easier task. 
The patented system works by 
alternately dropping mainsail cars 
onto port and starboard storage 
racks. Headboard cars articulate 
and pass through the switch, 
reducing stack height even more. 
Cut car stack height in half by 
flaking the sail alternately to port 
and starboard of the boom.
