Surprise

 |
The main jeer bitts which overlap both the companion coaming and the reinforced mast partners. The main topsail sheet bitts are positioned directly forward of the reinforced mast partners. |
 |
Two of the four chain pumps temporarily positioned. The inboard 'legs' of the chain pump assembly are seated onto the reinforced mast partners while the outboard 'legs' are seated onto the deck planking. |
 |
The four chain pumps temporarily connected with brass wire and positioned on the model. As you can see, the wire which will form the chain pump handle runs flush against the inboard face of the bitt uprights - these will be secured with a bracket allowing the handles to be unshipped when not required. |

The brackets securing the chain pump handle in place against the inboard face of the bitt uprights. |
 |
Away from the pumps, the chain pump handles are again secured with brackets to the inboard face of support pillars. In this manner, the chain pump handle could be extended a great distance allowing more men to work the pumps. |
 |
The crank handles positioned one forward and one aft of the chain pumps. The forward and after pumps are also connected with a removable bar which allowed both pumps to be operated by one row of men. |
 |
With a dowel mast temporarily positioned it is clear that space was at a premium on a fighting ship. One of the two elm tree pumps can also be seen. Although chain pumps were excellent for discharging large amounts of water from the bilges the water was dispensed through the dales by gravity only. Elm tree pumps on the other hand dispensed water under pressure and they were therefore vital tools for tasks such as fire fighting and 'wetting' the sails. |
 |
It was standard practice for chain pumps to be fitted in pairs, one to port and one to starboard, as it was generally only possible to work the lee side pumps during storms when the ship would have a substantial heel. Later, in the development of the chain pump, the cisterns of the port and starboard pumps were connected into one. This allowed both port and starboard pumps to be worked and dispensed through the lee side dales. |
