Turbinia's stern is curvaceous, to say the least.

TBA - propellors

Three shafts, three propellers. On what is now termed a displacement hull.
Safety Fence - to keep people off the prop shafts, and out of a low-headroom zone.

TBA - Turbines

StoneRoad2013 has posted:

The used steam from the turbines feeding into a condenser and back to the boilers - this means heated feedwater in a closed cycle which is more efficient, and conserves the fresh water supply.

TBA - Feed Pumps

StoneRoad2013 has posted:

Boiler water feed pumps - supplied from the condensate from the exhaust turbines.
Three turbines, two high speed for forward propulsion and the lower pressure third turbine was the brake and reverse gear.

TBA - Air Pump

Used to pressurise the two stoke holes to the boiler.
Over pressure keeps the fire in the firebox (reduces danger of blowbacks) and improves combustion - but the stokers have to work harder !

TBA - Stokers' hole

StoneRoad2013 has posted:

Teams of two stokers worked down here, there is another aft of the boiler. To improve combustion - and to prevent blowbacks - this area was pressurised; which meant the stokers had to work even harder - no wonder the funnel needed a repaint afterwards.

TBA - Information

Information Panel about the Turbinia Gallery, with the well known image of her at speed. There has been quite discussion about the identity of the gent on the conning tower.

TBA - hull cut-away

A section of hull plate has been replaced with clear polycarbonate to enable the engine room to be viewed. There is not a lot of room in there.

TBA - shafts

Charles Parsons was experimenting with propellers as well as turbines. He had to overcome design problems such as gearboxes and cavitation - all done without computers.

Almost at the water line view.

TBA - knife-edge

Turbinia's knife-edge bows. (no stem-post, as such)

Dimensions - 104 ft 9 ins x 9 ft beam and 3 ft draught with 44.5 tons displacement.

Top Speed - 34.5 Knots (39.7 mph / 63.9 kph)

TBA - from above

Deck, showing - from bows, Anchor, chain locker, cabin /deck house and bridge / helm, fore-stokehole, funnel, aft-stokehole, engine room control / access, engine room deckhouse, tender, crew access hatches, steering quadrant......and finally, her stern.

TBA - looking down

View from the Stern forwards. Items visible are......log, ensign pole, steering quadrant, two hatches (crew access), clinker tender, engine room roof / access, funnel, bridge / flybridge ...
....the long and thin profile is noticeable - length / beam ration is better than the 1 : 10 for canal narrow boats.

TBA - Log

traditional log - recording speed through the water. However, Turbinia made great use of the measured mile, just up the coast, usually used for proving trials.

TBA - Steering Quadrant

Deck mounted steering quadrant.

Turbinia's wheel is mounted horizontally, and turns the opposite way to the direction you want to go. Note, the limited forward view, at speed the bow-wave and general spray must have made seeing out difficult. No wonder that there is a handrail for someone to stand as conn on the roof above.

TBA - Funnel

This yellow funnel needed a repaint after every speed trial. Rumour has it that at times flames, not just smoke, came out of here.
