How do I choose the right code zero or gennaker furling unit for my boat? Data from 8 well-known manufacturers is reviewed and conclusions drawn to help guide you to an appropriate unit for your needs.
A quick review of the available data will tell you that sizing the correct furling unit for your boat is NOT an exact science!
The correct method for specifying a unit is by the Safe Working Load (SWL) and this is the one consistently available piece of information, across all manufacturers. Unfortunately, few, if any, people really know the SWL of their forestay or their Code zero tack load.
