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>
