I must replace a lost (daysailing) mainsail and would like to buy a used sail in reasonable condition or try to find a reasonably priced, new sail. If new, I will purchase a white sail with a row of reefing points. Any offers or help on this purchase will be appreciated. Who knows the significance of the sail numbers? Are they supposed to match the boat ID in some way? Should they be put on new sails. (I probably won't be racing my boat) I guess that I could ask the same question about the Carpi logo.
