I think you have arrived [at] and produced is a very plausible solution Keith. Looks good. cheers Pat

COG - not so much people forgetting, but info overload and therefore a quick indicator as to what 'state' the thing can be left in, or where not to step is needed. Not only do you need to be aware of the moving hazards of rotating turrets and machinery, but: the blast zone distances of all weapons, decoys etc, radio hazards ( working / normal distance, standard conditions and when refuelling, loading ammo), laser hazards, chemical hazard etc, trip hazards and so on-and on. Then you need to know what ventilation flaps, openings etc can be left open/closed in what state/condition the ship has been ordered to keep (different depending on the current situation - harbour, warning level, preparedness etc) - e.g. is it a condition A, B, Y, Z flap/opening, can this door hatch be left open or not in Action, Special Sea Duty, etc, or in what material state (how well/tightly the ship is closed down for various operational conditions). This is the RN marking system, the USN and other navies have variations and their own specific markings. Reminders are very useful and necessary, but some are probably more useful when it comes to an 'Accident Investigation' or a Court Case - something about protecting their Royal Highness' A%#@ cheers Pat

What do we know about the origins of the lifebuoy?
BANYAN replied to Sperry's topic in Nautical/Naval History
Hi Sperry, I had to undertake some research in this area for my current build. Unfortunately, this is a very wide ranging subject as I found out to my dismay . There were considerable parallel designs offered/being developed, and some difference in the evolution path of lifesaving device between the Navy and Merchant Service. The instigation of 'Sailing Rules' in the 19th century, especially with the advent of steam propulsion, resulted in some of these devices (or what had to be carried) being somewhat standardised. The earliest developments were simple flotation devices that could be heaved overboard as required; these included cork buoys, small wood rafts, even barrels/casks etc. etc. To try and simplify this I will concentrate on the major development and stay away from RNLI initiatives such as lifeboats, shore based rocket assisted lines etc. What I found was that the earlier developments led to what was called "The Common Service Lifebuoy" (CLSB) in the RN, but a ring shaped device was developed somewhat in parallel. I won't go into histories or earlier designs that led to these. Starting with the familiar ring shaped devices, these seem to have been invented (or at least patented) by a gentleman called "Kisby" (possibly in the RN or RNLI) - these were often referred to as the Kisby Ring. His initial design was more like a 'rope thimble' or 'horse collar' shape, but these very quickly evolved to the more familiar ring shape - the following are from his patent drawings. They were originally a cork filled canvas covered ring with ropes attached to hang onto to. These have remained in the same shape and base design ever since. The various 'Rules' introduced in the mid-19th Century required a ship to carry at least two lifebuoys but did not specify what types. The RN went with a device (CSLB) invented by Lt. Cook RN (no not that Lt. Cook ) which was a more complicated affair that was launched from the stern of a ship and had a smoke/light attached. That said however, some ships such as the 'Billy Ruffian' carried two, one each side on the transom - appears this may have been the custom for larger ships. I have attached a copy of one of the earliest designs of this (patent sketch). These developed quickly, so that by the mid-19th century, they were made from telescoping metal bars with a bottom weight to keep the 'arm' upright, copper balls for flotation, and a gunlock ignited flare/smoke. Later designs allowed the device to be dropped and the flare ignited with a single release mechanism, located within arm's reach of the helmsman. As best as I have been able to determine, most RN ships carried one of these on the stern and two lifebuoys. The CSLB was usually carried on the centreline of the transom outboard and when released slid down two metal rails, the lower telescoped leg dropping down to a stop, and the flare being ignited in the process. The two life rings were usually kept with one in the bows (vicinity of the foremast) and the other midships (vicinity of the main mast) - one to port the other to starboard. I have read that the usual practice was to have several man-overboard lookouts. I hope this helps? If you need further info please PM me. cheers Pat -
That was a very thoughtful and kind gesture; I am sure the 'karma' gods will reward. In the meantime you can be sure many a person has wished you well on this. regards Pat

Topsail schooner sail plans and rigging
BANYAN replied to Dr PR's topic in Masting, rigging and sails
Great overview of these rigs Dr.PR, you have put a significant amount of research into it. I can appreciate that effort as I am doing the same for a Steam-Screw Barque rigged ship - so many options to choose from and try to nail down the probable rigging and belaying plans. cheers Pat- 104 replies

Thanks for that Morgan; also adds weight to my earlier thoughts on the use of those end eyebolts in that they were the aft through bolt )of the axletree/transom, did replace the side bolts eventually, and were used to assist training of the gun. Many thanks for that pointer. I will have to chase down a copy of that article in MM. cheers Pat

HMCSS Victoria 1855 by BANYAN - 1:72
BANYAN replied to BANYAN's topic in - Build logs for subjects built 1851 - 1900
Dan, the Rigging Warrant, Contract etc I mention are all open source public records at the Public Records Office of Victoria (PROV) - the PROV are on line and you could order them if required? These documents are very specific to this ship though and would not be of much use for other ships as Victoria was very unusual. Might help you if you are trying to identify mid-19th century sail /rigging configurations. The Rigging Warrant is an attachment to a letter from Commander Lockyer (Build Superintendent) to the then Governor of the Colony (Sir Charles Hotham) and is located in VPRS 1189 Box/Unit 580 Unregistered letter dated 20 December 1855. The Specifications (Not the Deeds/Articles Agreement /Contract) for the Engines (Annex A) and the Ship (Annex B ) are on the web as a transcribed PDF document. A search for VPARL1854-55 NoA79 (1854-5 Victoria Screw Steamer and Dredging Vessel). The original document was published by the Government Printer 17th April 1855. The Contract (Agreement - Articles) is also in the PROV under VPRS 1189 P0 Box/Unit 580 (Unregistered) and dated 26th January 1855. Her Majesty's Colonial Screw Sloop (HMCSS) Victoria was designed and built on the principles of a warship (a one off design Screw Steam Sloop based on the contemporary RN Gun Despatch Vessels circa 1850s). She was built by a mercantile ship builder (Young and Co., at Limehouse Docks in London) for the Colony of Victoria (before we became a State in the Federation of Australia). While outfitted as a warship, she was never commissioned as a naval ship. She was minimum manned and rigged IAW merchant ship practices (according to Capt. Norman's preferences). She was rigged as what the Specification and other correspondence called a 'Barque', but in effect was a modified form of that which I have called a 'Steamer' rig. The Rigging Warrant appears to have been completed after she was rigged by the builder. This is not the Rigging Warrant referenced as an attachment to the Contract - which has not been found (if it ever existed). Is there a particular interest? I am about 40% into determining the 'probable' Rigging and Belaying Plans. If you have further questions on these documents, rather than clog the build log, could you please PM me? cheers Pat- 993 replies

Allan, I took a quick look through Kemmis without luck. I have found other examples of carriages showing these bolts, especially where the rear transom is sited further back, and this eye sometimes appears to be an extension of the securing through bolt as shown in the first illustration, but not in the second (from NMM). One thing I did find in Douglas (1855) though, in that his illustrations used in describing the positions etc of crew when drilling, have the gun tackles extending to this position. I am therefore reasonably confident they were used not just as gun tackles, but also to assist in pointing the guns (due to the angles). i am no gunnery expert and may be very wrong in these assumptions Sadly, there is a lot of info on 'gunnery' and the guns, but not for the carriages. cheers Pat

Hi again Allan, these eyebolts were in place in the 32 pdr 25 cwt gun carriages fitted in HMCSS Victoria (1855 supplied by the Royal Arsenal at Woolwich. These are of the Dundas Pattern, and only differ in having a rear chock rather than trucks, and a screw elevating device rather than a quoin. cheers Pat
-
Hi Allan, I have wondered the same thing My thoughts were that as they are slightly angled they may also have been used to assist in the 'training' of the gun. The angle would maintain a 'straight pull' on the eyebolt as the rear of the carriage was hauled around, much more than comfortably achieved using levers alone? Apart from assisting in moving the gun to an extreme angle of firing (chase?) it is also possible these may have assisted in turning the carriage sideways as sometimes seen when the gun was stowed fore-and-aft for rough weather? Another thought being that many naval carriages were also designed with the use in coastal batteries in mind (interchangeable). I have attached a book that may help Treatise on Military Carriages and Other Manufactures of the Royal Carriage Department_ W Kemmis (1874).pdf A tad busy to search at the moment, but if I get a chance I will poke through this for you. I have found some answers to my questions in this but it is a little limited in its naval carriage content. Another useful reference has been the The Mechanics Magazine which was contemporary engineering magazine that often included discussions and illustrations of naval guns, carriages etc, especially patents. If I get a chance I will have a scan through. Also, Captain Boxer's 'Diagrams of Guns' may be useful if you can find someone with a copy. Although mainly diagrams, there are sometimes helpful annotations on some fittings - unfortunately I don't have a copy as it is far too expensive for my pockets Blomefield, and his successor 'Dundas' introduced many innovations for the mass production of guns and carriages around this period, and it would be great to find a good reference on their work. Douglas (1855) and to some degree 'Garbett' both provide comprehensive discussions on naval gunnery but are a bit light on in their discussions of carriage fittings in particular. Hopefully, of some use? Pat

I may have cracked this while searching for information on getting the lower yards onboard. Lever, page 32 (1848 edition), explains: “When it [the lower yard] is lowered it will lie athwart the fore-castle , and over the Main Stay for rigging. In small vessels, a Mat is laid over the stay; but in large….”. This would perhaps suggest the listed mats were provided for this purpose as they specifically mention yards and stays (as does Lever); the mats may have had a secondary role as anti-chafing mats. This may explain the absence of other anti-chafing rigging in the Rigging Warrant, as these items may have been assumed to be made-up on board and used as required in different ships. What do you guys think? cheers Pat
