I have built a trailer for my 1990 Hunter 28. To construct the keel support and keel guide I need to know the dimensions of the keel parts: the width and depth of the "bulb", the overall length of the keel, the width of the "winglets" at the aft end of the keel, and the thickness of the vertical part of the keel. My boat is in the cold water so I can not measure it. Thanks
