Mathew Baker's early concept of ship hull design, ca. 1570
druxey replied to Waldemar's topic in Nautical/Naval History
You assume a distance of the stern post overhang using an estimated overall 85' 0", or a measured 6' 9". The ratio of 6' 9" to 18' 0" is very close to 1:2.5 which is what I suspect Baker used in his construction. That angle produced by that ratio is 22 degrees. See how that fits, Waldemar. -

You may find that the angle 20.5 degrees is actually a slope with a ratio of x inches in y inches (or feet). -
Nice wiggly tafferel rail, but the number of cross-grain sections will be difficult to work with....

It appears that the fairing over the sixth bulkhead from the bow needs further beveling. There should not be an angle to the garboard in the area where you have cut it. Check it out.

Mathew Baker's early concept of ship hull design, ca. 1570
druxey replied to Waldemar's topic in Nautical/Naval History
Thanks, Waldemar. I did understand that the limber channel drawings were representative, based on findings. Also I appreciate the clarification on the figures written on the cross section. Is the difference between the number and actual radius perhaps due to distortion over time? -

I've never seen a larger, clearer version of the plan that you are overlaying on, Waldemar. That figure written on the plan; does it read 5.2634? If so, what does this signify? I've been pondering your illustration of deadrise/limber channels. It begs the question as to when (in naval ships) the channels were moved to run above the floor timbers. The variants you show are fascinating, especially version E that runs centrally above the keel. -

I note some other near ratios on your latest iteration, Waldemar! Might they be exact, but for distortion over time and reproduction, I wonder? That 11.5 is sooo close to 12, for instance, as is 24.3 close to twice 12! -

Thank you, Waldemar. My impression is that ratios were very common - often decimal rather than duodecimal. -

Fascinating topic/discussion! What relationship is there - if any - between the span across the supposed first (lower) deck and the keel length and moulded breadth? -
You won't want to make the captain (whomsoever he may be!) cross by that missing cross! Coming along famously.

About the NRG
If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.
The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.
The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
