I have a carbon mast on my I20 and I love it. It is super-light when rigging/derigging the boat, and my back greatly appreciates this. They also reduce the pitching tendency of the boat a little, and make righting easier after a capsize.<br><br>I once dropped while raising the mast when the mast ball came off of the boat. There was no damage to the mast except for a small scratch at the mast head cap.<br><br>While aluminum is cheaper (maybe half the cost), in every other way carbon is more desirable.<br><br>Sail fast and have fun,<br>Alan Thompson<br>I20 - San Diego<br><br>

Alan,<br>Do you happen to know how much your I20 mast weighs complete with diamond wires, tangs, downhaul, etc.?<br>I was thinking an I20 mast might work nice on my 18sq. The I20 main is about the same size as the sq and the mast would be strong enough for a Spi.<br><br>Good Sailing <br>I'm off to check my lottery tickets<br><br>

Not sure of the exact weight. I would say the I20 carbon mast is maybe 1/2 - 2/3 the weight of a Prindle 19 aluminum mast, with both fully rigged.<br><br>Alan<br><br>
