    Leo:
    Surprise! You said years ago that you would probably never do it.
    It certainly is a comprehensive job; congratulations.

    There is a typo in your URL to my website; should be:
    atkinsopht.com/row/rowrpage.htm (missing the fourth letter "r").

    I have passed your URL on to Marinus van Holst at Delft as I know he will be interested.

    I will try to stay in touch.
    Next week is my 90th birthday.
    Regards,
    Bill

    Thanks, Bill.

    I decided to release an early version of the program once I had good
    on-water data for all 14 Olympic classes and when the manual grew to
    150 pages.

    I still have an enormous amount to do (e.g. energy, work, and power
    calculations) but the essential framework is in place and I have
    enough time now to slowly fill in gaps.

    I'll correct the link to your pages in the next iteration.

    I hear 90th birthday celebrations can be rowdy affairs. Good luck
    with yours!

    NoEyeDeer, "If someone has the actual table of offsets for any versions of this boat (original Herreshoff, or modified by Gardiner)"
    I'm sure I have offsets for the Herreschoff and the Gardiner modified version.
    Don't know if you can PM people on this site.
    Cheers A

    L. Francis Herreshoff published a simple lines drawing of a 17' double ender in Rudder in 1947, and included the lines in The Common Sense of Yacht Design Volume II. My understanding is a table of offsets was never published and probably never existed.

    Lines and offsets for two versions by John Gardner of L. F. Herreshoff's rowboat are in Chapter 1 of his book Building Classic Small Craft Volume 2.

    After I had posted the above I "ferreted" about in the books. It was in Gardner's book I had seen the offsets.

    Thanks, but someone else already sent me the offsets from Gardner's book. I just haven't got around to doing the modelling yet. On second thought I'm not sure there's going to be much call for it. A guideboat is obviously faster anyway, so makes more sense as a fixed seat benchmark. It's also an effing nuisance that the Gardner offsets are to the inside of the planking, and would have to be corrected everywhere to get offsets that Michlet or FIRM could use.

    Short version: I've been lazy. ;)
