Possible small error in The Masting and Rigging of English Ships of War

[allanyed]

I just noticed that Lees' sets of ratios that start with the lengths of main mast in the 17th century up to 1670 as 2.4 times the ship's beam.    The Complete Modellist published in 1667,  gives the length of the main mast as 2.5 times the length of the beam on page 2.  While this appears to be a small difference, for a ship with a 30 foot beam this is a three foot difference.  For a model of 1:48, this is a 3/4" difference, thus noticeable.   The difference will then follow for all other masts, spars, and rigging.  

 

On the  first page cover sheet it shows this copy is from of all places the Bibiloteca Nazionale Centrale di Firenze  (Florence, Italy).  This was first posted in the Nautical History section last year but some folks here may have missed it.

Anyone building a 17th century ship from before 1670 should find this work of help in scaling their rigging accurately.
