You should never consider anybodies writings as gospel and that certainly includes mine as well. As I wrote earlier I've even seen professors make huge dumb mistakes. I don't consider myself to be something that even the greatest minds are not.

I can't name problem issues with Gentry so far but I haven't read all of his stuff yet. Always use your own mind and intellect, not forgetting common sense, to check anybodies writings.

Maybe one extra note that is interesting in the larger discussion is the fact that Texel measurement handicap system EFFECTIVELY uses a 2.5 power relationship between speed and hull length. The relationship between wetted surface drag and speed is a quadratic one (2 power). This means the wave-making drag component is approximated by 0.5 power relationship on top of the wetted surface drag component. Both are continiously increasing functions for increasing speeds. Texel handicap seems quite accurate in its speed predictions relative to speed. It is not a big argument but I do think it is another element supportive of the model as presented earlier by me.
