Influence of the Spatial Pressure Distribution of Breaking Wave
Journal of Marine Science and Engineering Article Influence of the Spatial Pressure Distribution of Breaking Wave Loading on the Dynamic Response of Wolf Rock Lighthouse Darshana T.

(2019), Antonini et al. (2019). Due to the peculiar bathymetries and topographies of rock pinnacles, there is no dedicated formula to properly quantify the loads induced by the breaking waves on offshore rock lighthouses. Wienke’s formula (Wienke and Oumeraci (2005) was used in this study to estimate the loads, even though it was not derived for breaking waves on offshore rock lighthouses, but rather for the breaking wave loading on offshore monopiles. -
'British Small Craft': the Cultural Geographies of Mid-Twentieth
‘British Small Craft’: the cultural geographies of mid-twentieth century technology and display James Lyon Fenner BA MA Thesis submitted to the University of Nottingham for the degree of Doctor of Philosophy August 2014 Abstract The British Small Craft display, installed in 1963 as part of the Science Museum’s new Sailing Ships Gallery, comprised of a sequence of twenty showcases containing models of British boats—including fishing boats such as luggers, coracles, and cobles— arranged primarily by geographical region. The brainchild of the Keeper William Thomas O’Dea, the nautical themed gallery was complete with an ocean liner deck and bridge mezzanine central display area. It contained marine engines and navigational equipment in addition to the numerous varieties of international historical ship and boat models. Many of the British Small Craft displays included accessory models and landscape settings, with human figures and painted backdrops. The majority of the models were acquired by the museum during the interwar period, with staff actively pursuing model makers and local experts on information, plans and the miniature recreation of numerous regional boat types. Under the curatorship supervision of Geoffrey Swinford Laird Clowes this culminated in the temporary ‘British Fishing Boats’ Exhibition in the summer of 1936. However the earliest models dated back even further with several originating from the Victorian South Kensington Museum collections, appearing in the International Fisheries Exhibition of 1883. 1 With the closure and removal of the Shipping Gallery in late 2012, the aim of this project is to produce a reflective historical and cultural geographical account of these British Small Craft displays held within the Science Museum. -

PREFACE AND DEDICATION In so small a volume it would be somewhat hopeless to attempt an exhaustive notice of R. L. Stevenson, nor would it be desirable. The only possible full biography of him will be the Life in preparation by his intimate friend Mr Sidney Colvin, and for it his friends and his public look eagerly. This little book is only a remini- scence and an appreciation by one who, in the old days between 1869 and 1880, knew him and his home circle well. My earlier and later knowledge has been derived from his mother and those other members of his mother's family with whom it was a pleasure to talk of him, and to exchange news of his sayings and doings. In the actual writing of this volume, I have received most kind help for which I return grateful thanks to the givers. For the verification of dates and a few other particulars I am indebted to Mr Colvin's able article in the Dictionary of National Biography. It is dedicated, in the first instance, to the memory 6 PREFACE AND DEDICATION of Mr and Mrs Thomas Stevenson and their son, and, in the second, to all the dearly prized friends of the Balfour connection who have either, like the household at 1 7 Heriot Row, passed into the ' Silent Land,' or who are still here to gladden life with their friendship. -

Thomas Stevenson, Civil Engineer, 22.07.1818 – 08.05.1887
Thomas Stevenson, Civil Engineer, 22.07.1818 – 08.05.1887 Thomas Stevenson was the youngest son of engineer Robert Stevenson 1771-1850, designer of the Bell Rock and Isle of May Lighthouses, and the brother of engineers Alan and David Stevenson. Between 1854 and 1886, Thomas designed over thirty lighthouses with both his brother David and nephew David Alan Stevenson. Thomas Stevenson’s greatest achievement was the designing of a revolving light which earned him an international reputation. In addition to his innovative work as a lighthouse and harbour engineer, Thomas Stevenson invented the Stevenson screen used in meteorology as a shelter to shield meteorological instruments to enable accurate weather measurements to be taken. Thomas married Margaret Isabella Balfour and their only son, Robert Lewis Balfour Stevenson, was born in 1850. At about the age of eighteen, Robert changed the spelling of his middle name to Louis (pronounced Lewis). Expected to follow in his father’s footsteps and to join the family engineering business, R L Stevenson enrolled as an engineering student at Edinburgh University in November 1867. R L Stevenson spent the month of July 1868 in Anstruther observing as part of his engineering training, the work being carried out by the family firm of D & T Stevenson on Anstruther Harbour. He lodged with carpenter Baillie Brown in Cunzie House, Crail Road, opposite St Adrian's Church. A plaque on the side of the house records his stay. Stevenson wrote later: ‘though I haunted the breakwater by day, and even loved the place for the sake of the sunshine, the thrilling seaside air, the wash of waves on the sea-face, the green glimmer of divers’ helmets far below, the musical clinking of the masons, my one genuine preoccupation lay elsewhere’. -

Accounting for the Fund The Companies Act 1985 does not apply to all public bodies but the principles that underlie the Act’s accounting and disclosure requirements are of general application: their purpose is to give a true and fair view of the state of affairs of the body concerned. The Government therefore has decided that the accounts of public bodies should be prepared in a way that conforms as closely as possible with the Act’s requirements and also complies with Accounting Standards where applicable. The accounts are prepared in accordance with accounts directions issued by the Secretary of State for Transport. The Fund’s accounts consolidate the General Lighthouse Authorities’ (GLAs) accounts and comply as appropriate with this policy. The notes to the Bishop Rock Lighthouse accounts contain further information. Section 211(5) of the Merchant Shipping Act 1995 requires the Secretary of State to lay the Fund’s accounts before Parliament. -

A special point of interest arose out of the committee meeting & the Rougemont gathering (see page 2) In the Chair, Jenny George began the meeting. Last year's AGM minutes were read, confirmed & signed. Mention was made of an article on the Lundy Cabbage in 'British Wildlife' by Roger Key (see page 11 of this newsletter). The meeting's attention was also drawn to photographs on the LFS website taken by the first LFS warden.
