Which 420 Sailboat Are You Talking About? Trust us, we know it gets confusing when talking about the 420 Sailboat. There's the Club 420, the International, the Collegiate... which one is right for you? Well, in the latest installment of The Post-Opti Life we take a look at the family tree of the Club 420 and dispel some rumors and confusions about the boat. As always, we are looking at a sailing class from the lens of someone who is looking to move on from the Optimist class and isn't sure what to pick. The Club 420 class is a close cousin of the Olympic 470, designed for learning double-handed sailing skills like flying a spinnaker and trapezing, all while being easier on the bank and taking a beating as compared to more fragile International 420. Dive into the Club 420 Class in our latest video above, let us know what you think!
