    This guy used to work for NASA.
    I really enjoy his videos.
    See this one through, as he covers all the bases.

    I like his simplistic explanation (and graphic) of Reynold's Number.

    Did anyone else enjoy this video?

    It was enjoyable, but I don't think the AC75 designers will miss much if they don't pay attention.

    Yes, extremely cool.
    I just wish we could use some of the cool visualisations tools to record the actual flow of wind over a sail. I just don't think that wind tunnels with models and fluorescent dyes in water tanks really scale up to a 100 sq metre sail plan of a yacht in 15 kts or true wind.
