Another look comparing English and Dutch measurements

I thought it would be interesting to look again at the measurements for ships that we have both the Dutch and English numbers. All the ships were captured Amstedam Directors' ships:
             Dutch Dutch Dutch  Engl Engl Engl
Name         Guns Length Bean Depth  Keel Beam  Depth
Elias        34   132.5  30   13     101  27.5  11.5 
St. Matheeus 34   144    36   ?      108  32    15
Rooseboom    28   118    27   12.5    84  24.5  11.5
Groote Liefe 38   132    29   13.5   106  28.33 11

Ratios        Dutch/English  Dutch/English Dutch/English
              Length         Beam          Depth

Elias         1.312          1.091         1.130
St. Matheeus  1.333          1.125         ?
Rooseboom     1.405          1.102         1.087
Groote Liefde 1.245          1.024         1.227
This sort of information can allow us to estimate Dutch dimensions for ships for which we only have the English measurements, when ships were taken as prizes.
