Tirpitz Lines Plans

The battleship Tirpitz's lines plans were recreated from the original German hull offsets recorded on the Tirpitz's completed hull in 1941. In February 1941 the Tirpitz's commander, Kapitän zur See Karl Topp, requested a hull offset plan for both the Tirpitz and the Bismarck. In August / September of 1941, the shipyard created a separate table of offsets for the completed Tirpitz. We used both of these hull offset tables to model the Tirpitz's hull in 3D at a 1:1 scale from which we were able to create the body, half-breadth, sheer, and framing plans. For comparison, we also had copies of the original lines drawings which allowed us to overlay our drawings and check for accuracy. We believe the modeler will not find a more complete and accurate set of plans to recreate the shape of the Tirpitz's hull.

The lines plans for the Tirpitz and Bismarck are very similar, but not identical. The most noticable feature difference is the shape of the bow. The Tirpitz was constructed with an "Atlantic" bow, whereas the Bismarck had the Atlantic bow shape added after the ship had been launched. This resulted in a slightly different curve to the stem and to the ship's lines at the bow. The lines plans also indicate a slight change to the hull plating and framing just before and after the 320mm armor. The Tirpitz's side cover hull plates were cut in a straight line, whereas the Bismarck's plates curved slightly. Other differences between the ships include the flat bottom, the frames, and slight variations in the breadth of the ships.

Shown below are the Tirpitz's lines plans you will receive upon purchase. Each plan is individually plotted and includes salient dimensions, several highlight drawings, plan notes, and an abbreviation table.


Tirpitz Body and Framing Plan
 

At a plan scale of 1:100, plotted plan is 41" x 10" (1041.4mm x 254mm)


The Tirpitz's body plan shows the curvature of the hull at all major stations listed below. The Tirpitz's forward and aft framing plans show the lines for the hull armor and the individual decks at the ship's side. Every continuous frame (89 forward, 89 aft) on the Tirpitz is accurately drawn on the framing plans.
 
The Tirpitz's body plan includes stations 0, .25, .5, .75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 3 through 18, 18.5, 19, 19.25, 19.5, 19.75, and 20.

Tirpitz Sheer Plan
 

At a plan scale of 1:200, plotted plan is 52" x 8" (1320.8mm x 203.2mm)


The Tirpitz's sheer plan accurately models the ship's buttock curves using molded offsets below the armor and external hull offsets at and above the hull armor. The change occurs between WL9 and WL10 on the ship.
 
The Tirpitz's sheer plan includes buttocks 1, 2, 3, 4, 6, 8, 10, 12, 14, 16.

Tirpitz Half-Breadth Plan
 

At a plan scale of 1:200, plotted plan is 52" x 8" (1320.8mm x 203.2mm)


Just as the original Tirpitz half-breadth plan and offsets, this plan models the Tirpitz's waterline curves using molded offsets from WL0 up to the lower edge of the armor (WL9) at which point the waterline curves are drawn using the external hull offsets to WL20. For the modeler, there is an enlargement of the Tirpitz's forward and aft external waterlines at the ship's centerline.
 
The Tirpitz's half-breadth plan includes waterlines 0, .5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 16, 18, 20.
