Mast tackles/Burton pendants in 1763 Cutter

Recommended Posts

As usual, once I arrive at the point of making a particular part, I find the details confusing. This time it's about the mast tackles. The Sherbourne kit that I have doesn't illustrate or mention mast tackles or Burton pendants. Similarly, the 1763 cutter model I photographed in the Royal Dockyard doesn't have any.

 

On the other hand, one of the cutter models (1790) I photographed does show a similar tackle hooked to the base of the mast as follows:

Furthermore, Petersson in his book 'Rigging Period Fore and Aft Craft' shows what he calls a Burton pendant and tackle as follows (though I have added text to point out the difficulty I have with his diagram):

This made me think it might be a good thing to set up mast tackles. However, the moment I started looking at this, I thought that the diagram didn't make mechanical sense. It shows the runner going through what looks like a hook without a block -- which would mean it would have to run through a thimble.

 

When I looked up Marquardt's book on Eighteenth Century Rigs & Rigging, he shows the following arrangement:

This is very similar to that shown by zu Mondfeld and is clearly more sound (to my mind) in terms of mechanics.

 

Marquardt also supplies the following information about cutter rigging (following Steel) -- the last two paragraphs of which I am at a loss to understand:

 

"The mast tackle pendants were wormed, parcelled and served over their whole length. Each was doubled, and the bight was seized to create an eye which fitted over the masthead. The ends were then spliced together, and a single block was seized in the lower bight. The ends of all splices were tapered, marled down and served over with spun-yarn.

 

The tackle runners had a hook and thimble spliced into one end and were served over. They rove through the pendant blocks and were spliced round the strops of long tackle blocks.

 

The tackle fall was bend to a becket at the lower end of a long stropped single block, with the ends seized. The long strops, with hooks and thimbles spliced in, were hooked to eyebolts in the sides."

 

Here, I don't understand the terms 'served over' and 'long tackle blocks'.

 

I also don't understand which 'long stropped single block' is being referred to as having the becket for the tackle fall.

 

As a result I don't really know whether it's right to put mast tackles on, and, if I do, whether to try to mimic Petersson's diagram, or whether to go for the kind of picture Marquardt shows.

 

Any advice, comment or other will be, as usual, very welcome!

The description is exactly what you see in the last diagram.  A long block is much like a sister block.  It looks like two single blocks end to end. In some versions the upper sheave is larger than the lower to give some clearance between the parts of the fall.

 

A long stropped single block simply means that the strop is longer than you would find on a regular block.  It is what you see for the lower block of the tackle in the last diagram.  One end of the strop holds the thimble with the hook, the other end is the becket loop where the tackle fall is bent on.

Hope that makes a little more sense.

About the NRG

If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.

The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.

The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
