And you're saying that the power curve of a boat "at or near hull speed"
does not have an asymptote? Meindert Sprang wrote: No. I mean JAXAsshby. Sorry, I was trying to goad him into one of his classic explanations of hull speed, which are always good for comic relief. ... As I have always learned it and according to the mathematic literature, an asymptote will NEVER reach or cross it's associated curve. My understanding is that it might intersect (usually doesn't) but will never cross. ... So if the power curve of a boat would be an asymptote, the boat would never be able to reach hull speed, which is not true. If you apply enough power, the speed WILL get higher than hull speed. Sure. "Hull Speed" is not a hard limit. But in some cases the boat will sink under her stern wave, in other cases you're looking at trying to apply tens of thousands of KW to gain a knot.

... oh, Meindert. You spoil all the fun. Just when I was beginning to toy with dougies -- what him telling one and all what a genius he is -- you come along and point out the high school math involved. damn! maybe next time. Oops, sorry :-)) have fun Meindert. I will! Meindert |

dougies, what word didn't you understand? I mean in addition to asymptote? I understand every word, Jaxxie. What I don't understand is why you contradict yourself. Does the power/speed curve for boats have an asymptote or doesn't it? More power = more speed. This has an asymptotical limit, though.

Any Naval Architect would agree to your statement.

for the krying out loud kriste sakes, dougies.

in other cases you're looking at trying to
apply tens of thousands of KW to gain a knot. Fresh Breezes- Doug King no. or least "no" until maybe 10,000,000x "hull speed" dougies, stay out of conversations that are beyond gune's capabilities, for you and gune are twins separated at birth. |
Rod, it doens't. dougies was just spouting again, waaaaaaaaaaaaaaaaaaaaaaaaay

brian, please stay quiet. That way no one will realize you learned everything
