While we're at it, 3-deckers...

Ship Madrid drawing
1765 San Carlos 94 (note the backswept, archaic-style upper stem and huge "porch" galleries)
1769 Santissima Trinidad 114 threedecker
1779 Purisima Concepcion 112
1780s unknown 112 (Meregildos class or maybe San Carlos rebuild?)
1784 Santa Ana 112
1780s second unknown 112
1790s unknown 90
1800 another Meregildos
1804 unknown 112 by Retamosa (another Meregildos?)
Obviously these are not all to same scale, but does this look like a better way to compare drawings? (Also obviously, it only works with the smaller Madrid images.)
