The lines drawing is a more detailed view of the same information in the 17th century Baker style ship design. Like the older design, it shows the lines of the ship from multiple perspectives. In the 17th century the calculations would be done by the shipwright and measured by the ship carpenters. In the 21st century, this lines design can be used to directly frame calculate dimentions.

The top section is a half-bredth view of Virginia’s length featuring the 17th century narrowing lines.  This is very similar to the bottom drawing in the Baker design and allows the narrowing lines to be measured or computed.

The middle drawing is a profile of Virginia’s length and depth from bulwarks to keel. This is similar to the upper section of the Baker design. This allows the  vertical rise of each frame to be measured or calculated.

The bottom drawings show the dimentions of the key frames in a transverse view. This is simlar to the key frames shown in the Baker design, but with more precision. 

Virginia is wider as a percentage of length than most pinnaces of its time. This reflects a tradeoff of increased stability and hold space and decreased speed and manuverability. This is based on her intended use as a coastal vessel. Pinnaces built for privateering would have made the opposite tradeoff.

In the 17th century, shipwrights judged how well a ship would float by “eye”. The calculations of a good ship design was just starting to be written down. In the 21st century, the information in the lines drawing can be used to calculate how the ship will sail from its hydrodynamic properties. In both centuries, the ultimate test is to put the ship in the water.
