Length to beam 185/28ft = 6.6 or (better for stability considerations) 170waterline/28 = 6.0 is hardly a narrow hull. To improve stability the usual measure adopted was to increase beam. What displacements do you mean by "a builder's measurement" and "actual"? Light, legend, normal, full load? Why, ...

Oooops! Where I got 165ft from I don't know. I'm getting old! However, I don't see why you think a mean draft of about 10'6 is low. Taking 175ft as waterline length, the underwater block volume is 175x28x10.5 = 51450cu ft so that is 51450*62.5/2240 = about 1440 tons displaced Displacement is given a...

Hobart Town Courier http://trove.nla.gov.au/newspaper/article/2505044 The item bottom left may be of interest. Length 185ft is 20ft more than your Australian Sketcher figure. I've copied your drawing of Victoria, scaled it down 165/185 and the result fits between the stem at waterline and the rudder...

It's not as bad as that, and there are still libraries to borrow from. Snap one up at the £20-odd pound range if you can afford it. http://www.bookfinder.com/search/?ac=sl&st=sl&ref=bf_s2_a1_t1_1&qi=WOluR6FhesiUv9.0GzcAKdOocEo_1485768511_1:14:79&bq=author%3Dnorman%2520friedman%26title%3Dbattleship%2...

I wasn't "jumping down RegiaMarina1939 throat" just pointing out some ways in which you can see that something has gone wrong. For example the displacements. Also you will - should - get different results for hull strength if you say the ship is flush-decked or if it has a forecastle. Don't expect g...

RegiaMarina1939 Oh dear. Where have your figures come from? 5,120 t light; 5,300 t standard; 5,330 t normal; 5,354 t full load That cannot be. I know you have bunker 53 tons so that your standard and full load displacements correlate, but 53 tons of fuel won't take you very far. Weymouth's legend di...

Hood on Friedman I agree. But reading Covers from this time period is a bit of a nightmare and even those sources are not always consistent. The big problems are memos describing some change, which then doesn't happen. The best sources to resolve such problems are the NMM collection of as-fitted pla...

If you'll take some advice from someone who takes all his drawings from others -especially Gollevainen Hood and Krakatoa on here - the most useful source drawings are those which show what is inside the ship. It sounds obvious that the funnels are over the boilers, but knowing the internal layout he...
