Hi, I'm a relatively new sailor sailing on the bald, but windy, butt prairies. There aren't a lot of us (sailors) around here, so I hope some here can give me some advice. I have a C-18 with the standard rig. - 150 sq.ft. sail area with the 100% jib. There are days when I'm sailing and its not that windy and the boat could use more power. Is it worth putting a bigger jib on this boat? (I put roller furling on the boat last year.) Also, has anyone used a spinnaker on this or similar sized boat? Thanks, Doug
