Shroud tightness

Recommended Posts

Building MS USS Constitution. I would appreciate anyone's comments as to how tight the shrouds should be. Currently I'm tightening only to make the shroud straight as it connects to the blocks et al.


I'm concerned that once I start mounting the ratlines there won't be enough tightness and the shrouds will start sagging.


Your comments are sincerely appreciated.

This may not be correct, but I always leave my deadeye lanyards not secured so I can tighten up later after some of the other rigging has messed it up.  I always just leave it tight enough to not pull the other rigging askew and then use the shrouds to balance everything.  The tension , of course , should be equal on all shrouds.  I have had too many times when something has pulled one shroud off and I had to go back in and tighten the lanyard when I had already secured it and trimmed it.


The ratlines really should not cause any sagging in the shrouds if tied properly.


Good luck!

We have the tendency to pull all standing rigging taught, which in fact is only partially correct. Although in real life, the rigging would have been pulled taught, the weight of the material would pull it into a catenary, which is quite visible on photographs. This is not so easy to reproduce without looking untidy.


I would also consider the relative humidity during the conditions under which you are building. High humidity tends to tighten rigging made from natural fibres due to water uptake and swelling (which is counter-intuitive), while lower humidity tends to slacken it. You account for this in order to not have surprises during different seasons of the year, if these entail large humidity variations.

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.
