You: Why Dave; why now?
Me: Well, I've two talented kids; the younger mentioned my stopping with the lectures. Then enthusiastically asked, 'Dad, can I help you set up a blog?' Moments later, Me: 'OK, that's a great idea, thinkin' they might just read it someday.

Surface tension is a wonderful thing, if you are a wasp, or a boat. I guess you have to have a hydrophobic surface contact, but boat hulls are usually of that character, or can have a surface waxing to create better opposition. I wanted to notice that water stretches like a rubber surface. In boat design this means that a hull should first ‘stretch’ the water …. not ‘cut’ into it like a sharp bow can. However above the water where waves crash into the bow, a sharp surface is preferred as it requires the least energy to reject the momentum of the wave. The round bulb on the bows of huge tankers are not just for decoration and they might be a good place for sonar/radar/guidance systems, but it also stretches the water before it cuts into it. I remember on Lake Geneva, with David Driscoll as the sailing counselor, there were a large group of sailboats, called scows which had a smooth platelike bow and would skim over the water, not cut into it as our traditional sailboats would. In the regatta, where Dave was 1st and I was 2nd, as we had all challenged a local yacht club in a nearby lakeside town, the scow boats would go around the course twice as we sailed them once. They were longer as well, so the hull speed was greater. They also would be a terrible design for an ocean sailboat which would encounter waves often, a wave could crash on the top and force the bow to dive like a rudder on a diving submarine…. not a good thing. The triangular bow was also stronger against external forces. Navy ships, especially destroyers look almost like a knife in the water. A sub has a tough target if it tries to stop them from the bow or stern…. so that leaves only the sides that need protecting… and that’s where all the guns are.
When I get it out, I’ll show you the picture of my Grand Uncle Harry’s boat that he had in NYC in the 1920’s thru the 1940’s. It was a sloop and had no engine. He sailed it. In the 1940’s he designed ships for the Navy, I think they must have been the Essex class, as many of the quickly designed and built ships where splitting in half and sinking, according to my father-in-law. Well, that’s all for now.
