20807now hull speed, was Re: mast options for Ruben's Nym ph
- Jun 4, 2002In general, I agree with you. The one that gets me is abbreviated boat
names, tho I also originally thought OSB mean "one sheet boat".
In this case, there is an explicit definition of the D/L ratio we are
using (though actually it is NOT just displacement/length) in an
earlier post in this same thread. I seem to recall it is displacement
in long tons (2240lbs?) divided by the cube of .01 times the waterline
length in feet, IF I remember correctly. S/L is speed/waterlinelength
(knots and feet, I think).
I think SHP is shaft horsepower, and O/B must be outboard motor.
LWL is a common and conventional abbreviation for waterline length.
BTW, I forget where it is on the web, but a guy in Australia or New
Zealand or someplace south of the equator like that (I forget which,
it's not that I think they're all the same) has a free program which
purports to calculate resistance for hulls like this and even has an
"evolution" algorythmn (sp?) to come up with low resistance shapes.
Unfortunately, I don't remember the URL.
