"The Ezzy Skinny Mast makes ANY sail work better...not just ours!" Pre-preg is the key to acheiving a superior weight-to-strength ratio. The Ezzy Skinny Mast gets its superior strength from the 50% extra thickness of its walls. The small diameter makes the Ezzy Skinny a dream to sail. You'll notice the improved handling right away in your jibes. You can buy the perfect combination for your sail quiver. That means fewer masts. The general rule when mixing tops and bottoms is: choose a shorter bottom with a longer top. David Ezzy comments, "It is a life altering experience the first time you use an Ezzy Skinny Mast! You have got to try one out!"
