  1. Should cannons weigh a lot more?

    Not entirely. The carronade carriage is between twice and three times the weight of a standard truck carriage fitted to long guns of the same weight. Additionally the ammunition weight is higher for the same weight of deck ordnance and powder savings are diminished by the large bore and heavier shot even when the proportion is much lower. A 24lb main battery gun is given in tables as 92.6 cwt with carriage and stores. A 32lb frigate main battery carronade as 71.6 cwt with carriage and stores. This is a relatively minor difference, for the compromise in penetration and ease of use at gunnery range - the loss of 24 lb double shot to obtain similar performance from a single 32lb ball is questionable at best too. The 18lb gun can be had for the same total weight on board as the 32lb carronade. A far better option if available... at least until the introduction of a unified 32lb fit in long, medium and short guns soon after the period in question, because of the commonality of roundshot (if not of shell and hollow shot, where carronades had a different, smaller ammunition)
  2. While Frigates may only have a single magazine, I have seen multiple plans with a powder room for filled cartridges forward and a magazine, with stored bulk powder, powder handling room and store for filled cartridges under the aft platform (or vice versa). Commonly powder in filled cartridges was passed to the upper deck from one store and to the fo'csle and quarterdeck from the other, as the different requirements of powder for the different ordnance were simplified that way.
  3. Swedish 2nd rate "Spiran" by F.H Chapman

    It is the '1797' Chapman proposal, I'd guess.
  4. ship's draft affecting speed

    Not really. At this period: Draft = lines of the hullform, as drafted by the maritime architect. Draught = depth of underwater hullform from the keel to the waterline, not including the false keel in most cases. In this respect the Draft has a huge impact on the speed of the vessel, and her leewardliness, but the Draught has a far lower impact, and differences in lading are often compensated by taking on additional ballast, either as shingle or water to keep trim and balance within acceptable/comfortable levels. Trim and the carrying of the appropriate amount of and arrangement of canvas are also extremely important to the performance of the vessel, and often too much canvas will slow a ship if she is pressed by the head and heeled too much.
  5. I believe the plan, and the others for the same "Java 1815" from collections.rmg are for HMS Java, a fourth rate frigate. The quoted armament is for USS Java 1815, a '44 gun' "fifth rate" frigate, which served for a while against Algiers in the 1820s. This ship appears to be as large as the RN vessel, and has a larger battery of heavier guns. The RN frigate was one of 5 in her class of 24lb gun ships. 30 24lb guns, 28 42lb spardeck carronades and 2 24lb spardeck guns.
  6. What might be a more common occurence is that the magazine couldn't keep up with the requirement for filled cartridges (only a portion were normally made up, more were filled in expectation of engagement, but these supplies would be rapidly exhausted. The powder room was busy filling empty cartridges through the engagement and feeding them to the magazine and then to the decks were they were required).
  7. The gunner's vade mecum gives the number of discharges which may be safely made as 20 in the first 80 minutes of an engagement, (of which the first 3-4 could be discharged as fast as they could be loaded (roughly 2.5minutes per complete cycle, performed safely)). For longer engagements the interval between shots after the first 80 minutes would be 5 minutes. Thus for a 90 minute engagement, 22 cartridges per gun, with up to 44 shot or mixed shot and grape or 22 shot, chain or grape if fired singly would be all that would be required for most ordnance that were carried.
  8. The basic round shot allocation for channel service were generally around 20-30 rounds per gun lower than for foreign service. Other than that I only have the table for Admiralty supplied ordnance and gunner's stores. The same ordnance would get slightly different allocations when used on different types of vessel or on different batteries, but the differences are small in most cases.
  9. Usually the supply of specialist ammunition was *very* limited in the RN practice. No more than 7 rounds per gun of Case, Grape and Dismantling to 80-100 shot. For the lower deck guns the supply was lower 3-4 of grape and dismantling to ~70-100 rounds of shot. Carronades similar proportions in the common bore sizes.
  10. Usually you have the bowsprit supported by the stem head, and framed by the two innermost hawse pieces (the knightheads) (cant frame timbers arranged in front of the forward most main frame) which are all internal to the rabbet (the stem is an external piece to the apron). So they are usually inside the planking of the bow. Outside in the chocks there will be a gammoning piece, which has a slot through which the gammoning is passed around the bowsprit to hold it down firmly on the stemhead - the figure piece is one of the upper parts of the extension of the stem timbers which covers the forward and lower edge of the chocks and supports the figure head.
  11. I'd use a very fine plastic rod (I recall using heat softened and stretched sprue) rather than thread for the rigging tbh. Much easier to work with a dab of superglue (use tweezers to dip both ends of the rod into the 'blob' then move into position and hold for a second) than to tie off pieces of thread.
  12. Wappen Von Hamburg may be too bouncy

    Consitution was thicker high on the hull than RN ships, themselves significantly thicker than French practice. She had a hull heavier built than a third rate of 74, let alone a 4th rate or fifth rate of standard construction.
  13. USS Constitution

    Actually, as built the Consitution sailed with a mixed battery of 14x 12pdr and 16x 18pdr guns, later replaced by a full battery of 32x 32lb carronades, before being reduced to 16-20x 32lb carronades during the period just before her victories over the RN frigates in the war of 1812. So she was truly a spardecked frigate.
  14. It uses 32lb long guns and 32lb 25cwt gunnades. It was however a poor gun platform according to the NMM, being prone to excessive pitch and roll.
