18 mm Switch T-Track 
Battcar Systems
For masts with sail grooves, 18 mm slug-mount 
track uses a unique system that allows mast-up 
installation. Use high-load slug-mount tracks on 
boats over 12.2 m (40') at sail headboard locations 
at full hoist and headboard locations when sail is 
reefed. Drill/tap track and switches fit masts with-
out sail grooves. Join drill/tap track sections with 
splice links. Order one per track section. Boats 
with larger sail areas should use long switches to 
accommodate more cars.
Mounting Kits and Endstops
Slug mounting kits are available for flat or round 
mast grooves. Order one kit per track section.
Switch track includes screwpin stops for easy car 
and sail removal below switch. Stop at masthead 
also included.
About Switch T-Track Battcar systems: see feature pages at 
beginning of this section.

** Use HC8811 high-load track on upper part of mast to reinforce HL system headboard locations. Mount using 50 mm hole spacing at 
headboard location at full hoist and headboard location at each reef point. Reduce weight in other areas by alternating holes to 100 mm spacing.     
***Switch may be shortened to 605 mm (23 13/16").
