Expo rigging ?

Thread starter #1
I have a rigging question of the Expo vs: 14.2 sloop. On the sloop, which has about 10 so. ft. less of mainsail then the Expo the mainsheet runs between the end of the boom and the traveler and then to the center of the boom. On the Expo there is no traveler and the sheet is just connected to the middle of the boom. Why the different attachment points ? I tried to get this question to Catalina engineers and couldn't find a way to send it.
