Rob, at the rate we're going, it's already apparent that this clipper Staghound is another unique tribute to Donald McKay's creative genius. My only other request about the current cutwater decorative treatment is to add a single curved molding at the base of the cutwater, similar to what's seen on Glory of the Seas. It strikes me that this embellishment was added to minimize the wedge shaped appearance of this particular piece resulting in a more graceful appearance.
-
To me, nothing shows the genius of McKay's unique bow structure than actual historic Glory of the Seas pictures. When you look at those massive navel hoods which dwarf her larger than life figurehead it drives home the point that unlike headboards, these devices are integral to the hull of the ship.

Rob, Vladimir supposedly overlaid the Cornelius McKay Staghound bow profile on my sketch in red lines. If that's true, than my sketch is almost exactly the same. Your cutwater as it is now is fine, it just appears to me that your original pencil lines look just a little closer to how it appears in my sketch. If you print out the sketch on an 8 & 1/2" × 11" paper it should be exactly 1:96th scale. Then you might be able to see what I'm trying to describe better.

Rob, not all the way back but doing so at a gradual tapering inner curve. The Glory of the Seas picture you chose is perfect to illustrate how the cutwater blends into the stem to maintain the profile of the bow. You can also clearly see how this property accentuates projection of the figurehead as well. I've included my Staghound bow sketch so you can view how the graceful cutwater curve quickly intersects the stem. In doing this sketch, I relied heavily on what we learned in our research on Glory of the Seas as well. I also included a second curved molding as on the other clipper since in my studies I've seen this same feature consistently illustrated too. On your model, the outer depth of the cutwater is fine, it just needs to be a little trimmed back to match the photo and illustrations.
-
Rob, those beautifully done navel hoods really extend the prow of your Staghound and give her a genuine clipper bow. One observation I offer is that on your original outline, the cutwater had a higher curve which appears to accentuate this feature a little more gracefully. It also more accurately reflects McLean's statement that this piece appeared to descend in unbroken curvature until it blended with the waterline. The end depth where it provides a mount for the figurehead is fine.

Rob, that looks like a bow detail from a lovely Frank Vining Smith piece. I would appreciate seeing the entire work, as it looks quite colorful. Once again, this structural work demonstrates McKay's nautical design brilliance. It may even go back to his designing and building fishing boats in Nova Scotia. Those vessels had to be sturdy and tough for the type of work they were employed in. Here, we see the cutwater as the central backbone of the prow. Then two navel hoods sandwich this piece identically on both sides with the lower level of the cutwater extending the prow while doing double-duty as a sturdy base for figureheads. Meanwhile, the triple layered devices above provide a more than stable base for the massive bowsprit-jibboom just above while also providing a mounting point for the back of a figurehead and giving shelter at the same time. If you look at the Scottish tea clipper Cutty Sark you'll see that her bowsprit-jibboom mount above her bow and not into the built-up hull as in American clippers. Maybe that design philosophy was a difference too.

Rob, At this scale, your staghound's starting to look more like a chihuahua 😉 Either your navel hoods are too large or figurehead's too tiny. I'm resharing my sketch to aid in your scale evaluation. The staghound figurehead is 90" (7 & 1/2' like the Athene figurehead. Like her, the naval hoods terminate around the dog's front shoulders. The sketch is done to 1:96th scale with 8' verticle lines. I traced the Alexander Hall plans, which besides her bow profile was just about spot on. You can use the scale on that print as a guideline, as my trace was exactly the same.

Rob, Staghound bulkhead height, including monkey rail was 6'6" from the deck. Main rail height was either 5' with an 18" monkey rail or 5'2" with a 16" monkey rail. While it's not specified on this vessel, other McKay clippers had a 5'2" main rail height with 16" monkey rail. On Glory of the Seas the outer sheer rail molding was about 1' shorter than the internal main rail height. For a 5'2" main rail the outer sheerline would be about 4'.
-
@rwiederrich Rob, your Staghound is shaping up beautifully. I hope this reminder isn't too late for your build. The keel was described as being built in two sections, was 46" deep, with 36" projecting beyond her hull making the internal portion just a thin 10" deep in the McLean article. However, in the Cornelius McKay letter in addition to bottom planking being 4" and wales 5" thick he stipulated (excerpt attached) that the keel section beyond the hull was just 30" deep making the other portion of keel inside a more sensible 16 thick."

From his description, Duncan McLean appears to be listing these dimensions as taken from the main deck. That's at least how I calculated the aft poop deck dimensions. The inner fore part of the stern post would have a 2 foot aft rake, while the outer aft end would be vertical to accommodate the rudder. Meanwhile the forward stem aft inner end would have a 6 foot forward rake, while the outer end which joins the cutwater may have a different forward rake to match the vessel's clipper profile. I'm working on a rough sketch to illustrate this for Rob.
-
Rob, the only way a stern piece could be both vertical and have a 2 foot aft rake is if it was shaped like a trapezoid (picture a very skinny, ridiculously thin slice of pie) the outer edge, just like the Cornelius McKay model depicts would be vertical, the inner edge would slope or rake backwards so it's a 2 foot aft rake. That would make the further left higher red deck bubble the right position. Forget about the 2 foot fore rake and the further right lower red deck bubble, they're totally wrong. Incidentally, I double checked my deck and portfolio plans and they both appear to have the correct 7 foot distance from mizzen mast center to base of the poop deck bulkhead.
-
Rob, the stern of Staghound projects about 7 feet beyond the stern post. The stern post itself has a rake of 2 feet. A fact which everyone else seems to miss, just like the stempost has a 6 foot forward rake. Would that stern post rake then push the stern back 9 feet? That would also possibly push the stern poop deck back 2 feet, meaning the fore of the poop deck being 35 feet from the taffrail. I need to double check my dimensions to see if these factors were accurately accounted for.
-
Based on dimensions supplied by the McKay Shipyard to Duncan McLean for his Staghound article, she was just 37 feet wide on deck at the fore of her 44 foot poop deck. Central apartment was 13 feet wide, flanked by two 12 foot wide cabins with the Captains quarters on starboard and First Mate's on port. Incidentally, in his letter to Captain Hall, Donald's son Cornelius referred to her name as being one word, not two and so did Buttersworth in his painting.

@Kenchington Trevor, in the mid '90s I went to see the 1797 Frigate USS Constitution "Old Ironsides" in drydock having the hog in her hull corrected. It was an amazing sight. There were all of these massive blocks with sand pouring out of them at varying levels. This procedure was how US Navy restorers straightened out her badly hogged keel. During this extensive rebuild, in preparation for her 1997 200th Anniversary Sail, restorers discovered that the designer Joshua Humphreys had originally specified several massive diagonal riders both fore and aft. They were intended to stiffen the vessel and contribute to anti-hogging. They had been removed, most likely when she was converted to a receiving ship and eventually lost to history. During their research these riders were rediscovered in Humphreys' plans and instructions. This confirms that the US Navy as far back as the 1790s did indeed rely on ship's plans. How does this relate to Donald McKay. For a short while, Donald McKay was a Supervisor at the Brooklyn Navy Shipyard. He only remained for a short while, since he wasn't received well by the men who resented taking orders from an immigrant. He would have had to be well versed and familiar with military practice, including drafting of ship's lines. However he accomplished it, McKay was consistently designing, building and launching the largest packet and clipper merchant ships in the world, including the 1847 packet barque Ocean Monarch and California clippers Staghound, Flying Cloud, Sovereign of the Seas and the largest four masted, four decked wooden barque ever launched, the monster ship Great Republic. Donald McKay too became the largest vessel in the world after the loss of the Great Republic. Inerestingly enough, all of these magnificent vessels had similar diagonal riders installed as specified by Joshua Humphreys.

@Rick310 @Kenchington guys, it wasn't my intention to touch off a firestorm about the creative process of ship designers and builders from almost two centuries ago. My focus was on the meticulous accuracy of our specific approach in resurrecting extreme clipper Staghound Donald McKay's pioneer clipper of the California clipper fleet. Just from a logical viewpoint, I personally can't see how a half-hull model would be able to accurately predict hydrophonic properties. Being that it's only half of a hull. It makes sense that a vessel would first be drafted on paper, then possibly a full hull mock up to provide proof of concept. In such a case, the half-hull working builder's model would then be crafted to develop full sized molds. This is of course pure conjecture on my part which I've had no opportunity to confirm. Regardless, there are a few of Donald McKay's ship's lines still in existence. Of all places, this beautiful tracing of Donald McKay's extreme California clipper Flying Fish resides in the Bergen-Sjoforts Museum, Bergen, Norway.

@sob You're correct. In his Nov. 19th, 1896 letter to Captain Hall, Cornelius refers to his hand crafted Staghound builder's Model as being the sole surviving one of its type. He states that some surviving fancy models of his father's ships may be laying 'round somewhere but all of the working models were destroyed a few years ago. Since his dad died on Sept 20th, 1880 sixteen years earlier, this conclusion seems quite accurate. In his McKay biography, Richard reported that his relative Donald when late in life, broke, discouraged and to avoid freezing to death out of desperation resorted to cutting up and burning his working Models as firewood! Cornelius also wrote that he knew of no other correct model of his father's clipper ship existed. He made it himself from the lines of the ship as they were laid down on the Moulding loft floor. He also mentioned that he made drawings of her as well. I'm still trying to relocate them as they may be in the PEM, Salem, MA. Intriguingly, Cornelius adds that often the first working Model was most always altered on the Moulding loft floor in the process of laying lines down and then builders kept records of their revisions in offset tables. That implies more often then not, even a builder's working Model didn't exactly match the vessel as eventually built. Cornelius emphasized the uniqueness of his builder's Model as his was taken directly from the final lines of the clipper ship as she was actually being constructed. This makes the Cornelius McKay Model and drawing the absolutely most accurate version of Donald's California clipper fleet in existence. I have in fact discovered two working Models of McKay clippers in the Museum of Fine Arts, Boston, MA. They're the final extreme California fleet clipper Romance of the Seas apparently crafted by George B. Upton and McKay's sole, four decked monster clipper, the four masted barque Great Republic. I edited the original to give a closer look.

@Kenchington Trevor, I corresponded with a very generous lady at the Bostonian Society by email. Besides many wonderful pics of the original 1850 half-hull model, she sent me digital copies of the entire Cornelius McKay typed and handwritten letters. An intriguing fact is that Cornelius mentioned he included line drawings of the ship as well. She also included an ultra rare Chinese export painting on Stag Hound as well. In respect, I've left their watermark on although I later secured another for $25.00 watermark. In the highly detailed appendix of Richard McKay's book, he mentions that The Peabody-Essex Museum, Salem, MA has the only Donald McKay manuscript which he was preparing for a planned European trip for marketing purposes. A single example is the beautifully detailed construction illustration of the twin packets Star of Empire and Chariot of Fame.
