As I recall, that attempt didn't work particularly well....

But our little boat with a wide flattish transom considers hull speed
(1.34 x sqrt(LWL)) a suggestion rather than the law. It seems the AC
boats and other newer sleds are more advanced that way.


Two points he

1. Hull speed only relates to displacement hulls. Planing hulls such as
the aforementioned sleds are another story.

It also only applies to displacement hulls with a L/W of less than
around 3 or 4. When you get to the 8-10 range, you can easily exceed
hull speed, as catamarans (also displacement hulls) do.
