Interesting Club 420 Systems:


This special block allows your spinnaker the necessary rotation but prevents your halyard from twisting.


The 57 mm Carbo® ratchet block’s lightweight, strength, and great grip ensures heavy-air holding power, while providing that soft touch for light-air trimming. Like its International 470 cousin, a lightweight bridle has replaced the traveler to handle the mainsheet. When fully sheeted in, the bridle pulls the boom to centerline without tightening the leach, ensuring optimum sail shape when sailing upwind. 90-degree fixed-head blocks are shackled to the boom.


T2™ Carbo blocks make the ultimate lightweight, Gucci set-up. Use low-stretch Dyneema® line and splice the T2s in a cascade system. To add a becket, simply tie around the center of the block. The 16:1 vang system is led to the top of the centerboard trunk, through the clam cleat with a fairlead behind it. The tail can be reached from the rail while hiking.


About the Club 420:

The Club 420 is a spirited but durable double-handed one-design that forms the base of active local, high school, and collegiate sailing programs throughout North America. Used as a stepping stone to Olympic class racers, the C420 not only allows youth sailors to master the spinnaker and trapeze, but teaches them how to race as a team. Currently there are over 5,000 class-compliant boats on the water. The Club 420 has three approved builders: Laser Performance, Zim Sailing, and Sturgis Boatworks.
