Seriously. The Cumberland, Boston's "other famous frigate", is very well documented with deck plans, inboard profiles and sail plans as an 1856 corvette-conversion, from the US National Archives (which I do possess.) Even Howard Chapelle called her "magnificent". The last American frigate to go into battle under sail (at Fort Hatteras, 1861), she fought the Ironclad Virginia in March 1862 for forty minutes, and sank with her colors flying and her guns firing. 121 brave sailors lost.

I have been progressing with a small/medium kit before plunging into another long term development.

 

All designs/laser cut files are done, including three PE sheets, and now I am working on drawings. Once all drawings are complete, I shall start building the model for the manual, and may do a build log.

 

This is the gun brig Adder, of the Acute Class of 1797. My two main sources state it is a 14 gun brig, 12 x 18 pounder carronades and 2 x 24 pounders in the bow - but they may have been 12 gun brigs, as the only way to get the extra two carronades in position is to fill the stern chaser ports.

A intriguing layout.

The 24 pounders look as though they would be difficult to control, especially as the breaching ropes either side of the gun would have to be of such different lengths. I can see the gun slewing all over the place when recoiling.

Might not the guns be mounted on rails or sledges to stop this?

I thought that, but I still feel this is too early for such carriages, and I suspect later gun brigs changed to sliding carriages as a result of the lessons learned from these 2nd generation vessels. Also, it looks like the second gun port from the front was for the long guns, so they would need to be moved.

 

ETA - Plus the fact that fore deck droops down means that it must have been designed that way specifically for carriage mounted guns, presumably to lessen the recoil.

Seems more likely that they would have cut an additional pair of ports aft the main-chains, than to permanently arm the stern ports.

 

 


I dunno, given that this appears to be a ship designed for a specific task/roll, (get a lot of guns into shallow waters, close to shore), it’s quite possible that some of the conventions that we’re familiar with don’t apply.
 

Just my observation.

If I added an extra gun port aft of the main channels when every plan of the Acute Class (and there are a lot of them) does not show this, then it would no longer be an accurate (or as near as damn it) representation of an Acute Class gun brig, but fantasy. As Andy points out, it seems the fore deck was designed specifically for carriage guns, to minimise the recoil of the carriage. The drop down at the fore deck is significant.

 

Having said that about the plans, they did 'Troll' me in one area, the main channels and mast. On the main profile the main mast is a couple of feet forward of where it is indicated on the deck and cutaway profile plans. I always use the main profile for the hull and major fittings and the deck for the deck fittings positions) . However, when I fitted the fore most main channel to my model, which secured just one chainplate, I realised this single channel was too far forward (just aft of the side steps) of the main mast (how did I miss this when drawing the parts..). The deck and side cutaway profile chainplates/channels are not the same as the main lines plan. Easy enough fix, though, I just had to re do the aft most main channel to incorporate and extra chainplate slot.

 

The rudder appears to have two tillers, the lower one I assume was fitted with the tackle for the wheel, running under the upper deck, and the upper tiller having an auxiliary role

The deck 'droop' at the bow was called - wait for it - camber. (Deck beams and decks 'round up';  decks do not camber across.) The usual reason for this forward droop was so that the cables came aboard above the deck without the hawesholes being placed to interfere with either headwork or a wale. In this case it would help control recoil.

It looks like the stern chase guns would impede the tiller range of motion.


Not as much as you might think. The effective range of a ship’s rudder is somewhere in the nature of 30 to 35 degrees port or starboard. Any further and the rudder begins to act as a brake, and any gains in turning speed is offset by more dramatic losses in forward movement, a critical factor in turning a square rigged ship to be able to miss getting caught in stays.

The upper tiller was an auxiliary, as there is another tiller arm that runs below the upper deck (which is operated with the ships wheel). So the upper tiller arm may not have been fitted in place if not required.

I cant say its a beauty like the Speedy, but its good to have some more odd kits to build as well. I was always thinking you might do a Bomb vessel at some point, but this gun brig is definitely unique and it will be really interesting to see how it turns out when finished!     

Current builds: HMS Victory (Corel 1:98), HMS Snake (Caldercraft 1:64), HMBV Granado (Caldercraft 1:64), HMS Diana (Caldercraft 1:64), HMS Speedy (Vanguard Models 1:64)

Funny you say that, I have considered more than once whilst developing this if it's worth continuing, and abandoning the development, as it's not exactly a looker...

Beauty is in the eye of the beholder! 😜  

 

If ever I bought from another manufacturer, cough, 😱 it would be for an unusual ship like a mortar/bomb vessel.  Partly why I leapt at the Trial when it came out, just something different to the usual suspects we see built. If you can make these “oddballs” commercially viable all power to you Chris, I like seeing them being developed.

The first kit people buy is usually something they find to "look good" on the shelf. However, the more they build the more they start to look for doing something different.  From a general selling point of view, I think you will benefit from having a variarity of Royal Navy kits to offer your customers. And so far I think you have managed that quite well! And it is always exciting to see what comes next.

Even my wife loves the Trial Cutter. So much so that she said it can be displayed in the living room, and that;'s where it is.

 

Adder does have a couple of things going for it, it has a nice flat stern, so easy to plank there, and I have done my best to make adding the pre cut bulwarks around the bow as painless as possible - plus you get two full fat 24 pounders!

 

It seems these were not coppered straight away, but on average a year after launch, so I will do the bottom white.

I recall reading the Admiralty Court of Enquiry for the loss of HMS Levant, 20, in 1815 when she and HMS Cyane fought the USS Constitution, that the crew was unable to shift their two long nine pounders to the stern chase position, because the sloop was unable to steer with them in place. This was after the Cyane had surrendered, and the shattered Levant was trying to escape.

Chris,
From something I recently read, these gun brigs were rowed when inshore in shallow water. Perhaps the tiller was used to steer when rowing? The wheel being used when under sail in deeper water and using the drop boards.

You might consider providing a set of oars in the kit, as this would make an interesting display, what do you think?

Oars would add a little more expense, as they would be a whole sheet of pear, and the pear sheet count is already very high for what I hope was a £240 kit. It is something I have thought of, however, so will see. I still may put it on hold anyway.

Just thought I would mention on here - Vanguard Models will be shut From Saturday 23rd September until 7th October. The last date for kit orders is Tuesday 19th September and for small package postal orders, Thursday 21st September. Orders made after closure will be processed upon re-opening.

 

I am being made to take a two week vacation, first in 8 years!
