Lil bars in bottom of manual ?

[Bleiz]

The little bars or scales in the bottom of a ship in the recognition manual, you know that go *black white black white*, do they represent a static value in meter or yards? If so, what is it, it would be easier to find the lenght of the ship. ATM i do a rule of 3 to find it with the height of the mast. Also, im all new to nautical jargon, so what exactly is a knot worth? I saw a video that made me believe that 1 m/sec = 2 knots, is that correct ?

Well,

(1) 1 knot = 1 nautical mile per hour
(2) 1 nautical mile = 2,000 yards = 1,828.8 meters
(3) 2 nautical miles = 3657.6 meters
(4) 1 hour = 3,600 seconds
(5) 1 m/s = 3,600 meters per hour = approx. 2 nautical miles per hour

so, yes, 1 m/s roughly equals 2 knots

Almost exactly right, and, as they say, close enough for government work.

I used to think that a nautical mile was exactly 2000 yards, or 6000 feet. Then I learned that it's 6080 feet, or 2026.2 yards.

Then I found that, according to the American Practical Navigator, the International Extraordinary Hydrographical Conference of 1929 set the official nautical mile at exactly 1852 meters, or 2025.372 yards, or 6076.1155 feet. This is because it's exactly 1 meridian arc minute at sea level.

Weird, isn't it, that a nautical mile is actually a perfect metric distance?

But it doesn't change panthercules's answer; 1 m/s is still pretty close to 2 knots.

Tnx thats very helpful, but what about the bars i was talking about ?

:o The what ?

Sorry I just found that 'title' amusing.

The 'bars' I believe are graphical scales.

:rotfl: I agree; it sounds like something out of a Jules Verne novel.

Bleiz, I haven't seen the SH4 book myself, but I agree; it's probably a measurement scale for the ship drawings. Question now is, is it feet, yards or meters?
