The #3171 Big Boat double-sheave Dodger block provides a simple, clean way to route bridge-mounted traveler control lines to the cockpit on your cruising boat. This 4:1 system features an integrated side-mounted 57 mm Carbo block that leads line from an elevated position, down through a deck mounted block and under the Dodger to a Cam-Matic® cleat within easy reach of the crew.
"For people considering the comfort of a Dodger, this is a great way to help solve the problem of accessing your traveler control lines," said Jon Malcolm, project engineer.
Blocks feature ball bearing sheaves allowing cars to easily adjust under load and release instantly in a gust. Compact, high-strength Carbo AirBlock® components keep traveler weight minimal.
