Henry V's Grace Dieu and the wreck in the R. Hamble near Bursledon, Hampshire

This paper re-evaluates the documentary sources for Grace Dieu in the light of recent research, describes mid-19th to mid-20th century speculations and investigations about a wreck in the R. Hamble and presents evidence for the identification of the wreck as that of Grace Dieu .     

The Wreck of the Ex-Slaver James Matthews

This contribution presents the progress of investigations into the wreck of the ex-slave ship James Matthews, wrecked off Western Australia in 1841. The James Matthews wreck site preserves many elements of the vessel’s structure, with the result that the basic architecture of an actual transport vehicle of the Middle Passage has been recorded in detail and can be analyzed in depth by maritime archaeologists working in tandem with naval architects. The discovery of the James Matthews wreck has made possible cross-disciplinary research of a type not previously feasible for the illegal period of slavery in the Atlantic.     

The Resinous Cargo of the Java Sea Wreck

A number of blocks of resinous materials were found in the cargo of a 12th‐ to 13th‐century shipwreck, discovered in the late 1980s in the Java Sea near the Indonesian islands of Sumatra and Java and excavated in 1996. These well‐preserved blocks presumably were trade materials used for religious, medicinal, cosmetic, decorative or practical purposes. Such materials, derived from plants and termed exudates, generally include frankincense, myrrh, ‘gum benjamin’, liquidambar, dragon's blood, dammar, copal and amber. The source of the cargo resin could not be determined from the site. Investigation by nuclear magnetic resonance (NMR) spectroscopy has revealed that the molecular structure corresponds to that of modern resin from the plant family Dipterocarpaceae, known in trade as dammar and closely resembling Group B copal and amber. Other molecular classes of exudates are excluded. Such materials are not present in the Middle East, which then cannot be their source. The NMR spectra differ from those of Group B samples from Australia, Papua New Guinea and Indonesia, but resemble those from India or Japan. The spectra indicate that the saline environment had a similar effect on the molecular structure to heating and aging.     

Rigging the Pepper Wreck. Part 2—Sails.

Discovered in 1993 at the mouth of the Tagus River, the SJB2 shipwreck—or Pepper Wreck—was tentatively identified as the Portuguese Indiaman Nossa Senhora dos Mártires , lost there on its return voyage from Cochin, in India, on 15 September 1606. Its archaeological excavation led to a tentative reconstruction of the hull, based in contemporary texts on shipbuilding. Further analysis of these texts allowed us to propose a reconstruction of the rigging.

Rigging the Pepper Wreck. Part I—Masts and Yards

Discovered in 1993 at the mouth of the Tagus River, the SJB2 shipwreck—or 'Pepper Wreck'—was tentatively identified as the Portuguese Indiaman Nossa Senhora dos Mártires , lost in this place on its return voyage from Cochin, in India, on 14 September 1606. Its archaeological excavation led to a tentative reconstruction of the hull, based in contemporary texts on shipbuilding. Further analysis of these texts allowed us to propose a reconstruction of the rigging.

The use of a high-resolution 3D Chirp sub-bottom profiler for the reconstruction of the shallow water archaeological site of the Grace Dieu (1439), River Hamble,UK

The remains of Henry V's flagship, the Grace Dieu, currently lie buried within the inter-tidal sediments of the River Hamble (S. England). Previous archaeological investigations have been hindered by difficult excavation conditions resulting in a poor understanding of the dimensions, shape and degradation state of the hull's deeper structure. This study therefore aimed to image, characterize and reconstruct the buried remains of this vessel using a high-resolution 3D acoustic sub-bottom Chirp system with RTK-GPS positioning capability. The accurate navigation and high-resolution data that were acquired enabled the construction of a full 3D image of the site that not only identified the remains of the wooden hull, but also features buried within it. In addition, the degradation state of these buried wooden remains were investigated by calculating reflection coefficients while a hypothetical larger reconstruction of the Grace Dieu's hull was achieved, through the use of the ShipShape ship design software package.     

Provenance of Coals Recovered from the Wreck of HMAV Bounty

Coal samples from HMAV Bounty were analysed using standard techniques to shed light on their provenance. Petrographic analysis indicated they were Carboniferous, with high vitrinite and liptinite content and a mean random reflectance of vitrinite of 0.99%. Palynological analysis indicated the samples were derived from the Middle Coal Measures, Westphalian B. Combining coal rank (vitrinite reflectance), age, knowledge of seam distributions and coalfield history indicates the most like source to be the Durham Coalfield, possibly the Hutton or Low Main Seams. These coals were mined along the valley of the Weir in the latter part of the 18th century.

The Rigging and the 'Hydraulic System' of the Roman Wreck at Grado, Gorizia, Italy

The hull of the Roman wreck at Grado has been preserved under the cargo of amphoras. On the site, a lot of wooden elements of the rigging are preserved, including deadeyes, blocks, and toggles. Three possible bitts were identified, one of them sculpted; two were nailed to the hull while one was loose. Near the keel a lead tube, protected by a wooden box, has been interpreted as a bilge-pump but more probably it was a suction-pump. The tube would have been connected to a piston pump which has not survived. Possible explanations for its use are presented.

Site Charting and Environmental Studies of the Monitor Wreck

Abstract

Marine geological and geophysical techniques have been applied to studies of the Monitor wreck to chart the fragments of the wreck and to determine the corrosion state of the remaining iron and the state of the geological and oceanographic environment in the immediate area of the wreck. Methods included magnetic surveying of the wreck site, computer calculations of the magnetization of the Monitor iron, and comparisons with magnetic measurements on iron artifacts from the wreck. Piston coring of the strata immediately beneath the wreck and near-bottom current measurements revealed evidence on the sedimentation rates and sediment transport at the site; these data confirmed interpretations made from high-resolution subbottom reflection profiles across the site.     

The Wreck of the Warship Northumberland on the Goodwin Sands,England, 1703: an interim report

The Northumberland, a third‐rate man‐of‐war was lost with all hands during the Great Storm of 26–27 November 1703 on the Goodwin Sands—famously known as ‘the ship swallower’. It was rediscovered in 1980 by local divers following the location of a sister ship, the Stirling Castle. Since, the primary concern has been to record exposed structural remains, ordnance and artefacts, and interpret the wreck formation of the site. This paper describes the results of this work, and discusses in particular the size of the keel, the use of chocks, and standardization of ordnance in the Restoration Navy through reference to comparable ship‐finds and historical records.     

The Marausa Wreck,Sicily: interim report on a boat built in the Western Imperial Roman tradition

In 1991, the wreck of a late 3rd–early 4th century AD Roman merchant vessel was discovered on the west coast of Sicily that had carried North African amphora, tubuli, and other ceramics. The hull was dismantled and raised in 2011, including a keel hook‐scarfed to stem and sternposts, 39 pegged mortise‐and‐tenon joined planks, 43 frames with an irregular pattern of floor‐timbers, half‐timbers, and futtocks fastened to the planking with treenails and copper nails, sister‐keelsons and evidence of two stringers, 36 ceiling strakes, and the base of a bilge pump. Many repairs are indicated. The fairly flat bottom and round bilges, mortise‐and‐tenons, sister‐keelsons and lack of a coherent framing pattern, place the boat in the Western Imperial tradition.     

The Pepper Wreck, an early 17th-century Portuguese Indiaman at the mouth of the Tagus River, Portugal

Found in 1993 of the rocks of the fortress São Julião da Barra, at the mouth of the Tagus River, the SJB2 shipwreck—or Pepper Wreck—was tentatively identified as the Portuguese Indiaman Nossa Senhora dos Mártires , lost at this location on its return voyage from Cochin, in India, on 14 September 1606. Its archaeological excavation disclosed a collection of artefacts from the late 16th and the early 17th centuries and allowed the study of the surviving hull structure. The evidence suggests that the Pepper Wreck was a typical Portuguese Indiaman, similar to those described in Portuguese 16th century ship treatises, with a keel of around 27.7 m and an overall length of nearly 40 m.     

A Chain Pump Recovered from the Wreck of the Warship Northumberland (1703)

In 2008 the remains of a chain pump were recovered from the wreck of the third‐rate man‐of‐war Northumberland, which sank on the Goodwin Sands in the English Channel, during the Great Storm of November 1703. Chain pumps were vital equipment and integral to the safety of the ship. Historical evidence is mined for comparative material, and the recovery, conservation strategy, study and recording of this artefact using X‐ray and CT scanning are discussed. Information gleaned, hitherto absent from the historical and archaeological record, includes details of the pump's chain, hook and swivel, valves and roller.
