AIDS TO NAVIGATION

Six stations, each carrying a character that cannot be confused with any other. Everything that moves on this site is keeping one of them.

READING A LIGHT

Fl(3)W15s43m24M

ORDANE ROCK, RUNNING NOW

  1. Fl(3)

    The form

    Flashing, in a group of three. The lamp is dark for most of the cycle and shows a short burst of light. Three panels of glass turning past you, one flash each.

  2. W

    The colour

    White. Red and green appear too, but never decoratively. A red sector means there is something under the water in that direction, and it means nothing else.

  3. 15s

    The period

    Fifteen seconds from the start of one group to the start of the next. Count it with a watch and you have identified the station, without needing to see anything else.

  4. 43m

    The elevation

    Forty-three metres above mean high water. Height sets how far over the curve of the earth the light can be seen before the horizon takes it.

  5. 24M

    The range

    Twenty-four nautical miles in clear air. This is the last number, and in fog it is the first one to stop being true.

THE REGISTER

Six stations, six rhythms.

SECTORED LIGHTS

The same lamp tells you something different depending on where you stand.

Saltmere Head shows white across open water and red across the ledge that dries at low tide. Nothing about the lamp changes. The glass in front of it does.

THE CHARTER

A light exists to be recognised. Not admired, not noticed, recognised. Every decision this division has ever made about a station comes back to a single question asked from the deck of a vessel in poor visibility: which light is that, and how long have I got.

THE KEEPERS

R. Vance, Principal Keeper, Ordane Rock
People ask what you do out there for eight weeks. You keep the light. That is not a modest answer, it is the whole answer. The light does not keep itself and it has never once been late.
R. VancePrincipal Keeper, Ordane Rock1968 to 1991
M. Oyelaran, Optical Technician, Division Workshop
The mercury float at Saltmere carries four tonnes of glass and you can start it turning with one hand. Nobody builds like that now. I am not sentimental about much, but I am about that.
M. OyelaranOptical Technician, Division Workshop1994 to present

THE DIVISION

First-order Fresnel lens, close

A lens that has not been improved on since 1822.

Concentric prisms bend a single source into one flat beam. Every station on the register still uses the principle.

Pharos Division does not exist. The craft that built it does.

Every rhythm on this site was derived from one idea and carried through every route, every hover and every transition. That is the part we would bring to your brand.
