Patrick, you need to find a copy of the polar diagram for your boat. This will tell you the maximum speed potential for windspeed, point of sail and sail size. Remember, as a displacement boat, you are constrained on the top end by your theoretical hull speed. I donít know what boats you sail on the Bay, but I have had the experience of going into horizontal stalls a couple of times on light displacement boats where a gust pined us over and we didnít have enough displacement/ momentum to carry forward boatspeed. Wound up getting dragged sideways a little bit. On our family cruiser, we do not have the rail crew to hold the boat upright and the constant feathering and square waves/chop knocks some boat speed off.

Most importantly, where were you sailing and what type of boat? I had to take care of some family business and wasnít able to get out on the Bay. Sounds like I missed a good one.
