Britannic 9 Plan ordering code: BR9 Price per sheet: $30 USD
This plan sheet is a drawing of the shell plate expansion. This drawing has never been found among the Britannic drawings. It was created using the Olympic framing plan and the Olympic shell plating plan. The plan was modified from Olympic to reflect the increased breadth of Britannic. The plan is of constant scale both vertically and horizontally. All hull plates on the starboard side can be visualized in this expansion. This plan will help the modeler in plating the hull.
Special Note: It should be noted that the shape of individual plates cannot be derived directly from the shell plating expansion. The shell plating expansion shows the shape of plates in the x and y dimensions. On the ship there is also curvature in the z dimension. The shell plating expansion is at best a general guide to the individual plate shape. The modeler will need to develop the true shape of individual plates directly on the ship. The advantages of this drawing are that it shows all the seams, butts and doubling in one drawing. As an aid to the modeler, notations have been added which show how an individual plate or strake is overlapped or overlaps those adjacent to it.

Addenda
From time to time information comes to light which requires that one or more of the plan sheets be changed. This section will display changes which are more than merely minor drafting errors. All changes will be made to the plan sheets from the date of the change noted here forward.
1. Date of change: 10/10/2010
Plan sheets affected: BR3, BR4, BR5a, BR5b
Nature of change: The port side water main group of HMHS Britannic (aft of #3 funnel) has been changed from the original configuration. The new configuration has the mains traveling further aft on the port side tank room roof before they enter the deck house. The reason this change is being made is because the tank room only occupied approximately the aft third of the port side of the deck house. The forward two thirds was the engineer’s smoke room. Changes are shown below in red. Changes also apply to RMS Britannic
2. Date of Change: 8/3/2011
Plan Sheets Affected: BR1, BR2, BR4
Nature of Change: New photo evidence has come to light necessitating the removal two ventilators. The ventilators were previously numbered 97 and 98. These are the two 20 inch sirocco fans on the port and starboard poop deck promenades. These vents were listed in the RMS Britannic specifications. Previous photo evidence seemed to indicate their location but a better photo which was only recently uncovered indicates that there were no ventilators in these locations. Probably these ventilators were inside the deckhouse somewhere. Below is the photo evidence. Also there are two images of plan sheet BR4 showing the locations of the eliminated ventilators in red. The second plan image shows the alteration of the ventilator numbering. Changes also apply to RMS Britannic.
3. Date of change: 9/19/2011
Plan sheets affected: BR3, BR4, BR5a, BR5b, BR6
Nature of change:
Forward of Funnels 1, 2, and 3 on the port side is an access hatch to the fidley vents. Recent study of archival and wreck photos have led me to alter the size and position of these hatches. The new positions which are identical for all three boiler casings is shown in the drawing below. Changes also apply to RMS Britannic.
