    The bow was a major design flaw on John Cobb's Crusader. When the boat nosed over after the forward planing shoe collapsed, the short very steep recovery area instead of popping the boat back up acted as a huge water brake and stopped the boat dead in its tracks.

    What did the redesigned bow on Mark II look like ?

    There was no Mark II. (Unless you count Lee Taylor's Discovery II, which had a whole different set of problems.)

    Crash video
    It occurs at ~1:59
    Probably too wide an angle/to far off to really see much.

    About the only "wreck" left was the jet engine.

    Yeah it looked like a nasty mess on the video. You can see the bow dig in and the back comes up to cartwheel and it just disintegrated.
