As Thomas Armstrong has so eloquently described it, Sjogin had her lines recorded this week with the able help of Steve Martinsen. Steve is one of the parties that will receive a set of the Paul Gartside plans. It is his dream to build a copy of Sjogin for himself. Just typing that makes me very happy.

Thomas came by late Wednesday afternoon and took some pics which are shown below. Here’s a link to the post on his always interesting 70.8% Blog.

Here I am applying one of the fingers to mark the location of the lower edge of the keel. This will define her profile.

…

Moving right along, more fingers are added, each pointing to the lap joints where the planks are joined.

…

Here the fingers are laid on the laydown, where each point is marked. Then a hopefully fair line is drawn between the points. At each crossing of the waterline and buttock lines, the distance from the centerline and the above the baseline respectively are recorded, resulting in a table of offsets. That table lists all the points that define the hull shape. It’s the essential information that allows the boat to be built.

…

Here Steve and I are setting up a batten to draw a line through all the recorded points. In practice not all points lined up in a smooth curve. Paul Gartside and Francois Vivier will take the measurements and fair them as they see fit.

…

After the lines are drawn, each height and half-breadth is recorded in the table. Since the whole boat is drawn here on only one side of the centerline, it was a challenge to make sure the offsets were measured properly.

…

The almost completed Table of Offsets. The first step in developing plans for Sjogin. The next steps involve measuring all of her construction details, the shape and size of the cabin, spars and everything else that the designers will need as a starting point for their own idea of what makes Sjogin, well Sjogin.

Thanks again to Steve for his able assistance and to Thomas for documenting the documentation.
