Quasi-standing wave, speedboat

  1. Feb 26, 2009 #1
    Hello people,

    i have just 2 questions and i would be veeeeery happy if someone answer me.
    First question is about quasi-standing wave on water from boats. If someone can explain me how it's made and what it is.
    And second question is about speedboats. What is maximum speed that they can go? Why they rise up? And what physical is about it?

    Thank you very very much if someone answer me on this things.
