I think that was probably the intent, but with the canvas going forwards from the conventional cabin shape to the cratch (once built of course) but also providing a section that was watertight and connected to the main conversion??
Maybe, yes...but a 'new build' fully riveted hull, which is correctly proportioned and topped with engine room and back cabin in an 'as built' style with an additional sympathetic conversion..you couldn't commission that level of 'new build' for the same price now?
They look like two inch guards to my eyes.
