    Daiquiri,

    Except if I am wrong and uploaded the wrong one (which I don't think), this is not the NPL4a graph but the actual hulls re-ran into Michlet at a much lower scale (0 to 2.5 kts)

    Where I think this can be more than adequate is in terms of relative values for comparing different designs.

    Finally, where I find this important is that this gives a feel about the expected figures for resistance and hence powering. Even if a ball park estimate within percents (5-10%?) it is always good to have a reasonable figure in mind.

    Thanks again

    I know, I was talking about Rick's post #11 and the relative graphs. You and Marshmat have been faster and have inserted 2 more comments before my reply. :D
    All the best,
