Description
Adkins skiff modeled from a set of offsets give to me by a friend who was building the boat. His offsets were off when he was laying it out. I modeled the boat and then corrected the errors so that the hull would be fair.

Remarkable work. What is an "offset"?
DENCOUCH
Offset is short for a "Table of offsets". When a boat is designed, it is drawn in 2d, and then the marine architect uses a scaling ruler to measure the vertical and horizontal points of importance. These points are usually drawn at a regular distance from the start of the bow of the boat, and are broken into equal segments known as "stations". When a boat is lofted for building, the table of offsets is used to transfer the points onto a floor or wall. After all of the points are down, they are joined by a thin and bendy piece of wood known as a "batten" Because the architect is measuring with a ruler points from his drawing, he may be off a bit with his measurements because of scaling error creeping in. Joining all of the points in real life with a batten will quickly show where the errors are, and those measurements can be corrected before any wood is cut. The measurements are usually taken from the waterline of the boat, with positive numbers representing measurements above the waterline, and negative numbers below. this link may help you understand. http://www.dixdesign.com/loft1-3.gif
