The Ships section of the website shows a low resolution image of the deck plans for this vessel. Is there a higher resolution version of that image available? I am collecting data for a radio-controlled sailing model of the vessel.

Hello FerryFan
Not sure which plan you are referring to, but if it is this one: http://www.tynebuiltships.co.uk/E-Ships ... a1961.html
There is a profile drawing of her at the bottom of the page.
If you click through as suggested then the following image will enlarge further if you click on it.
If you are looking for something even larger then I think you are needing the original builder's plans.
These might be available at Tyne & Wear Archives, see: https://twarchives.org.uk/
