I am planning to shop for a used mainsail and genoa on eBay or one of those used sail warehouses over the winter. I know my C30 TRBS has a I J P E of 43', 11' 6, 35' 6, 11' 6 respectively, but what actual sail demensions should I look for (for main AND headsail)? Are those the max or min sizes? On eBay for instance, the sizes and usually given as foot, luff and leech. Also, what weight sail should I be looking for? I am in the Chespeake bay, so I would perfer a fairly large genoa, maybe a 145 or 150. Lastly, the genoa must fit in the groove of the foil for the furler, how do I measure the size ? Thanks, I know this is a lot..... Mike
