Could someone please tell me what a knotical mile is in comparison to
the standard mile.
A nautical mile is 6,080 feet (1853.18 meters) and is equal to 1/60th
of a degree of latitude. A statute mile is 5,280 feet.
Also what does D/L limited speed: 10.08 kt. and Disp. Hull Speed: 5.90 kt.
mean.
Just guessing here, but the D/L should be Displacement to Length Ratio
and don't aske me how you figure it because it has been a long time
and I'd have to look it up. However, it's basic explanation is that
the longer the boat at the waterline, the faster it is given it's
displacement (weight). For example, a boat weighing 1,000 pounds will
act like a boat weighing 2,000 pounds if you shorten the length at the
water line and vice versa - a 2,000 pound boat will act like a 1,000
pound boat if you lengthen the waterline. There are a couple of other
factors involved, but that's the basic gist of the term.
The Displacement Hull Speed is the speed at which the designed hull
will efficiently travel.
I am just fooling around with a hull designer and would appreciate any
info.
Have fun.
