Determine size of traveler system (13, 22, 27, 32, 42, or 64 mm) based on mainsail area, placement on the boom, and mono- or multihull. See charts. Typical boat lengths are listed as a guideline only.
Typical Boat Lengths:
22 mm Small Boat: 6.7 - 8.5 m (20' - 28')
27 mm Midrange: 7.9 - 10.7 m (26' - 35')
32 mm Big Boat: 10.4 - 12.8 m (34' - 46')
Select size and length of track (sizes listed by width measurement of top of track in millimeters). Choose low-beam track if it will be supported the entire length. Choose high-beam track for spanning companionways, cockpits, etc.
Based on system size and purchase requirements, select a car and accessories that match track and load requirements. Select control blocks for the car.
A kit contains car-mounted components to make a 2:1, 3:1, or 4:1 system. 27 and 32 mm systems only.
Cars come standard with shackles for attaching the mainsheet to the car. Upgrade to a stand-up toggle with control tangs to attach high-performance ball bearing control blocks.
Choose end controls that mate with the control blocks on the traveler car for the correct purchase system, including a deadend, allowing clean-running lines. Use Carbo ball bearing end controls with toggle-mounted, ball bearing control blocks, or use ESP sleeve bearing end controls with ESP car-mounted, sleeve-bearing control blocks.
Options include end controls with attached cams, or purchase cams separately and mount remotely. See Traveler Systems for common systems.
Endstops are designed to absorb shock loads and should be installed when end controls are not used. Trim caps finish off track ends cleanly. Select high- or low-beam endstops/trim caps to match track. Low-beam, line-shedding endstops prevent snags. Sold in pairs.
Previous steps show the most common configurations. Other options include windward sheeting cars, soft attachments, coupled cars, track risers, and track splice links.
