I found to be what seems a recent photo where that's not the case, and now you're claiming it's a relic? I don't get that. Either it can be a factor or it can't be. If I may again... Compare a Catalina 27 and My Catalina 26. My waterline is 3 inches longer. That's because the 27 has significant overhangs on both ends. Overhangs are the part of the hull above the waterline forward or aft of the waterline/hull point. If there is a lot of hull forward of where the water meets the hull then you have a long bow overhang. Same for the stern. Heeled 30 degrees (quite a bit actually) the 27's waterline length just about matches my 26's. Any less heel and the 27 is shorter than the 26. Waterline length that is... So, what does it mean as far as speed goes? Three inches is 1/4 of a foot. So.. 1.33 * sqrt (.25) = ? 1.33 * .5 = .665 knots difference In theory, at least. Which can be easily hidden by sail trim, rudder position, sea state, etc Yes, I get that current is only a real help in a few instances. What about the gulf stream example? I don't think that changes direction does it? Current is not tide. Tides change direction. Currents usually do not. That's both right and wrong in so many ways.... Tides go up and down. Currents caused by tidal differences do change direction---one or more times per day, depending on whether you have diurnal or semi-dirunal tides. Currents in the open ocean--like the Gulf Stream or the Japan Current, do not change directions---at least during the time span of a normal cruise. Mark Borgerson Much better explination of tidal currents, Mark. Thanks Mark sure is more correct than Bruce. LOL! But, then again, perhaps that's not saying much. Wilbur Hubbard |
