In the typical Bermuda rig, the sails located in front of the mast generally deliver a higher percentage of the driving force. The stay that supports the leading edge of the sail causes far less turbulence than a mast, resulting in better airflow across the lee side of the sail. To take advantage of this fact, Bermuda rigs are shifting towards larger fore-sails and smaller mainsails. Fore-sails include jibs, genoas and staysails. The cutter, with its use of multiple foresails, achieves the same goal of placing a higher percentage of the sail area in staysails.
