Andrew Help!

I'm doing a deckplan for a broadsword class cruiser for someone at the cartographers' guild but I've run into a problem. I've used the side elevation of the broadsword on Andrew Boulton's website. From this I guage that the radius of the sphere is about 17m. This provides a volume (4/3 * pi *r^3) of circa 20.5k m^3. From this site, I see that there are 14 m^3 to a dt which makes the ship on Andrew's website some 1,400 dt, which is nowhere near the 800 dts it should be.

I know that Andrew is punctilious about these things - so I'm mistaken somewhere (and I'm not great at maths), so where have I gone wrong?
 
Your math is correct. Perhaps there is some fudge in the shape or you miscounted the scale.

EDIT: Nope, you counted right, it looks like 1m squares and a radius of 17m.

It should be about (I'd round) 13.5m radius for 800tons.

Ah, there it is! I was looking for Brook's version of the Broadsword and found it. It jives perfectly with my take of the expected dimension*. I'm not surprised, it's probably why I recalled liking it, and Brook is a nitpicker for correct volume too :)

Brook's Traveller Lowport

* even if the cutters stick out a bit and the legs would add to the total tonnage
 
Thanks Dan, I thought I was going mad...so it looks like I'll have to reduce the size.

Edit: oh man that is beautiful and puts my meagre efforts to shame. I might just refer the person who wanted the deckplan to these.

IIRC, the original GDW Broadsword had a radius of 15M, giving a sphere volume of 14095 cubic meters, or about 1007 tons, using the original 14 cubic meter ton. When that supplement came out, I just refigured the stats for a 1000 ton 'heavy cruiser', and put 2 more turrets around the equator. Then I added two of them with a sort of cylindrical waist struture for a 2000 ton 'super cruiser'. Oh, the fun that can be had from arithmetic errors...

But Brooks's corrected cruiser is cool, too!
