Rod Terminals

Special connectors designed for rod rigging, a favorite among racing and high-performance yachts. Why? Because rod rigging is super strong and lightweight, making the boat faster. These terminals keep the rod rigging securely connected, which is key for a stable and high-performing yacht.


What They Are: Specialized fittings used to connect rod rigging to the boat's deck hardware, mast, and other parts. Unlike wire rigging (made of cables), rod rigging uses solid metal rods that barely stretch and are incredibly strong. Rod terminals are built to work perfectly with these rods, creating a reliable and strong connection point.


How and When They Are Used: You'll mostly find rod terminals on racing and performance yachts where the rigging needs to be super strong. They're ideal for situations where the rigging can't stretch much and needs to be very strong, like the main support cables (shrouds), the forestay (front cable), and the backstays (rear cables).


Applications:

  1. Standing Rigging: Rod terminals are used to connect the rod rigging to chainplates, tangs, and spreader tips, ensuring the mast still is securely in place.

  2. Racing Yachts: Due to their superior performance characteristics, rod terminals are commonly found on racing yachts where reducing stretch and improving strength are critical.
