Spinnaker Pole Cars
Harken spinnaker pole cars feature recirculating ball bearings 
to permit adjustment under load. They roll freely on low-beam trav-
eler track to allow crew to adjust for optimal sail shape. Machined 
aluminum hardcoat-anodized races permit Torlon® bearings to 
transition smoothly from active to return race for 
smooth trimming or easing. 
Cars feature captive ball bearings, making them easy to load onto 
the track and to maintain. 
Strong, lightweight cars are constructed from one-piece 
solid aluminum that is Hard Lube-anodized for strength 
and durability. 
Ring fittings are 17-4 PH stainless steel and accept piston pole 
ends for end-to-end jibing. Midrange and Big Boat cars accept two 
popular toggle studs and Harken ball-end fittings. Cars are also 
available from Harken’s Custom Division. 
Use for:
Spinnaker poles
Whisker poles
See page 275 for replacement balls.     *Check dimensions of pole end toggle from suppliers listed.

Wire retaining clips keep balls 
captive, making cars easy to load 
and maintain. Composite corner 
keepers help keep ball bearings 
captive when the car is off the track. 
For a cost-effective option, CB+ cars 
can be modified to run on Harken 
non-CB track.
Cars fit low-beam track.
