The top 3 profiles are fitted, actual photos of near-perfect (orthographic) side-views, taken of the boats - on the dates - indicated, with their key features enhanced by line-overlays. Note on the profiles of Tradewind and Tally Ho (from their sail numbers), that these were actually port-side views, flipped horizontally. On all three, note many smaller features - particularly (just about everything) on their bow casings - varied from boat-to-boat.
The line-drawings at bottom reputedly depict "Tabard" - date (and correct spelling of "Tabbard") unknown. While clearly a vast improvement over our best-prior drawings, not all of the features shown here are known-100%-correct (though most certainly look to be).
Note the saddle tanks (lower right) are maximally bulged low down on the hull - exactly the opposite of usual - and this has been confirmed by another drawing (not shown), as well.
Note also in this new drawing, the deck accurately rises - the height indicated by the topmost pair of hash-marks, on either side of the drawing - over the length of hull indicated by the bar drawn above the periscopes. However along the same length of casing, its lower edge - actually a vent-line against the pressure hull - does not appear to angle down as steeply as apparent in the photos. This feature - visually important, accentuating the appearance of the rising casing - is about the only remaining, substantial question I have regarding this drawing - which I may update accordingly, if indicated by further comparison(s).
Meantime, this is certainly enough with which to proceed - with confidence - on a whole lot of the remaining work required!
