Thanks Don! So on that note, I've noted discrepancies over the years as to the complement of guns on the St. Lawrence, perhaps people here have been able to get to a better answer than I have. 112 guns is commonly cited, but I haven't found any evidence that actually backs this up. This all in turn messes with hydrostatic calculations and determining things like draft. I have two reputable sources that both cite 104 guns, but in different configurations;
One source (Lyon, David; Winfield, Rif (2004). The Sail & Steam Navy List: All the Ships of the Royal Navy, 1815–1889. London: Chatham. ISBN 1-86176-032-9.) indicates the following complement;
• Gun deck: 28 × 32lb, 4 × 24lb, 2 × 68lb carronades
• Middle gun deck: 36 × 24lb
• Upper gun deck: 32 × 32lb, 2 × 68lb carronades
While another source (Robert Malcomson, Warships of the Great Lakes: 1754-1834 (Annapolis, MD: Naval Institute Press, 2001)) indicates the following complement;
34 @32lb, 34 @24lb long guns, 34 @32lb carronades and 2 @ 68lb carronades.
Since carronades are not counted in a ship of the line's guns, both of these sets of numbers raise the question of whether St. Lawrence was a First Rate ship. In the Lyon/Winfield scenario, we're on target, but with Malcolmson's model, while displacement, gun decks and crew still supports First Rate, guns would only count to 68 guns, which would typically put her around a Third Rate, except that these only have two gun decks typically by the Napoleonic era. To that point, Lyon/Winfield's statement of 2 carronades on the gun deck is also a bit puzzling, as carronades are typically on the quarterdeck/upper gun deck. I know gun deck placement was done though, the HMS Glatton was an example with 68 pounders on her lower deck, but she wasnt a 3 decker. I'm a little skeptical of the 34@35lb carronades, but it makes sense to load up the upper deck with these light and intimidating guns given the role of the vessel, and at the time, loading up on carronades on the upper deck was being done (take the USS Essex for example. she only had carronades, and had to surrender without a fight to the HMS Phoebe which had long guns.
Just as a bit of trivia, figures from Brian Lavery, Nelson's Navy: The Ships, Men and Organization, 1793-1815 (Annapolis, MD: Naval Institute Press, 1989), 80-85, which proposes that typical 32-pdr long gun weighed in the neighbourhood of 5,500 pounds, while the weights of the other ordnance were approximately 5,000 pounds for a 24-pdr long gun and 1700 pounds for a 32-pdr carronade. So I calculated the weight, excluding shot and powder; in Lyon & Winfield's scenario, total weight would have been approximately 270 tons and 210 tons for Malcolmson's model. Assuming proportions similar to Victory for gunpowder and shot, we could probably add 35 tons of gunpowder and 120 tons of shot to those numbers. Its hard to imagine just the logistics of getting all of this to Kingston from Quebec in the 156 day window they had from laying the keel to launching her!
