Greeting! I find myself trimming the main on a Catalina 310 in San Francisco bay for some medium-serious PHRF racing. I have not sailed on a Catalina before, and the 310 seems unusually tender to me. With a 110% roller-furling jib and a relatively flat-cut main, she seems to carry an awful lot of heel in 15-20 kts of wind. We seem to mostly be driving on the jib upwind. Short of adding a lot of rail-meat, does anyone have any trim ideas? I want the owner/driver to try rolling up a little of the jib to reduce backwinding the main and get the weather helm under control. While I know that backwinding is not always slow, I can't imagine that it is fast to be carrying 15+ degrees of heel while flogging the main with the traveler all the way to leward. Unfortunately the boat has mid-boom sheeting and no adjustment on the backstay (it is in charter so has been "idiot-proofed" to a certain extent.) Any tips for : getting more draft down low/ getting more twist in the main / reducing weather helm / reducing heel / jib lead settings for this particular boat appreciated. You can email me directly : keck@visa.com if you wish. Thanks.
