Jeff, You left out one most important parameter............ The angle of heel should never - ever cause your beer can to tip over............. My daughter's boyfriend who absolutely had to have a sister ship of our Tripp-Lentsch thought fast meant lee rail under water and hanging on for dear life. When he found his Tripp-Lentsch (which by coincidence was also red like mine) and we sailed together, he sailed his way, but I never spilled my beer and beat him every time. Finally made a believer out of him: sail it on it's feet and let it fly............! Of course, my sailing style didn't bother him because he didn't drink beer and therefore was oblivious to the problems he created - but he did tip over his cans of soft drinks! Connie
