天滅中共全黨死清光!

a case off ... good screen. Yeaaaaaah

According to my calculation base on the ship plan from that period:


HMS Benbow's Beam is 68ft 6 in -> 137.2pix
That meant the ship Length OA = 714pix -> 357ft
As for control, I used the Draught 27ft 3 in ->55pix

That meant HMS Camperdown is 362ft is she is 5ft longer than Benbow.

Is my calculation correct?

Problem is that the length is for PP:

I'll have a look in my Conway 1865-1905 to confirm the length (assuming its not pp in there too!)

Most probably it is PP. Contrary to what DP posted, the PP definition is: Length between perpendiculars (lbp): The distance measured along the summer load water plane from fore to aft perpendicular is known as length between perpendiculars.
The fore perpendicular is where the summer load line intersects the fore side of the stem. The aft perpendicular is usually measured at the rudder post, as explained below.

I think the way DP scaled the drawing from the beam to get the length was as good a way of getting the length calculation right as any other. One of the uses of a decent plan/side view if you are unsure of oa/pp lengths, but have the beam.

I do not question DP method of scaling his drawing. His drawings are excellent.

Sorry double post. My home router was acting up again...
