Cal 20 Rigging Guide

Spreader Brackets:
The weakest area of a Cal 20 rig is the spreader brackets. An original spreader bracket is on the left. One of Seal's heavy duty spreader brackets is on the right. After a few years of hard use the original spread brackets tend to fail. There has never been a failure of a heavy duty bracket, making them a must for Cal 20's, especially on San Francisco bay.

The Outhaul is led inside the boom to a tackle system at the gooseneck end. The tail exits the boom after going through the tackle system. From there it goes down to the base of the mast and ends up on a swivel cam on the bridge.
