Lines drawings of the fore-deck

Outline

The slightly smaller inside perimeter visible in the drawing, marks the waterline.

Due to the fact that yachts are constructed symmetrically, only one half is drawn in each case: above the mid-ship's line you can make out the keel section, below the deck area.

Tip of the bow

In the upper half of the drawing, you can clearly see the frames and floor plates, which are joined to the keel, and in the lower half the deck beams, which meet with the the king plank in the middle.
The longitudinal beam runs around on the outside on both sides within the ship's wall.

Mast section

This section aligns directly with the bow on the right and gives an outline of the mast section with fore-deck and cabin.

At first glance, a lines drawing appears very confusing for a layperson. With a ship over 21 metres (almost 70 ft) long and a scale of 1:10, there are thousands of details to be included in a 2 metre (7 ft) drawing.
For this yacht, Josef Martin drew all the lines drawings on four single sheets each 1,5 metres (5 ft) in length.

Reinforcements in the mast section

On this enlarged extract from the upper lines drawing, you can clearly make out the reinforcements necessary to take on the enormous forces around the mast.
Especially noticeable are the two diagonal beams, which redistribute the forces of the chain plates for the shrouds into the deck.
Next, you notice the many parallel and perpendicular beams, especially on the deck (bottom half of picture).

The downward-facing semi-circle visible on the mid-ship's line marks the position of the mast.
The dotted, upward-facing half-ellipse visible above the mid-ship's line marks the position of the keel.
