The Birth of a 'Centennial Spray' in New Zealand!

These photos will (hopefully) record the construction of our Bruce Roberts
'Centennial Spray 38'.
MANY thanks to Blair Boats for making the project happen!

A close-up shot of the cockpit dorade-type ventilator, that will feed cool air into the engine room under the cockpit. An integral, long flap can be used to stop air flow through the dorade. This flap can be seen at the back (outboard edge) of the dorade, and is operated from inside the boat beside the companionway. An additional 100mm wide overhang is yet to be fitted to the edge of the cockpit seat, and this will further protect the air intake openings. The cockpit sole is of a ply/foam/ply construction, to maximise rigidity and minimise the number of framing members required under the sole inside the engine room.

Cockpit dorade
Forward vanity locker

The forward vanity bench and locker have been completed, but not yet fully painted inside. The bench top is made from solid 50mm thick Kauri with a 10mm wide Silky Oak trim. A porcelain basin will be fixed into the bench on completion of finish work. The doorway to the left (aft) leads into the shower, while the locker to the right (forward) will be used as hanging space. The small light-coloured disk at the bottom of the vanity locker face will house an LED footlight. These will be distributed around the boat for night-time passage lighting.

The exhaust lines from both the main propulsion motor and the smaller diesel DC genset are first run through water separators in the engine room, and then the resultant dry exhausts are routed under the berth in the aft cabin to exit the transom. A water separator system was chosen due to the long exhaust run that results from the centre cockpit configuration of the yacht.

Aft exhaust
Aft berth

The berth in the aft cabin has been framed up, and cabinet work has been constructed on either side. The small cabinet on the starboard side of the berth will house a diesel cabin heater, and this unit's exhaust will be conducted through the transom behind the cabinet face. A matching cabinet on the port side will conduct ventilation air from the house battery bank, that will be housed in sealed battery boxes under the forward end of the berth. Both transom vents will be run through baffled openings which prevent the ingress of water. Other equipment, such as the main battery charger and inverter, will also be contained under this berth.
