    I bought a new Ford F250 Tri-Flex Fuel Truck Go figure it runs on either hydrogen, gasoline, or E85. I returned to the dealer yesterday Because I couldn't get the radio to work. The service technician explained that the radio was voice activated. 'Nelson,' the technician said to the radio. The radio replied, 'Ricky or Willie?' 'Willie!' he continued and 'On The Road Again' Came from the speakers. Then he said, 'Ray Charles!', and in an instant ' Georgia On My Mind' replaced Willie Nelson. I drove away happy, and for the next few days, Every time I'd say, 'Beeth
  7. I once asked my senior hydrodynamics lecturers about the transition between the different modes. He would comfortably say that the flow detaching from an immersed stern marked the transition from displacement mode. Beyond that, there was nothing except shades of grey. What he tried to explain to me was that - if a hull is not in displacement mode, then it is planing. The phrases semi-displacement and semi-planing have evolved to deal with those hulls which are optimised to exceed hull speed, but not be subject to hydrodynamic trim and so tend to be somewhat slender - such as catamarans.
  8. The question I have here is for the transitional, or semi-planing region. So the flow has cleanly detached from the stern but there is no dynamic lift. Here, the hull is displacing the same volume of water AND some virtual amount. Thoughts?
