Richard Steffy The glossary is primarily relevant to the first two sections of this handbook and is not meant to be representative of the entire field of maritime archaeology. As an independent contribution, it is an exquisite source of information on ship construction terminology, but also a testament to the work of the late Mr. Steffy, whose influence has been instrumental to the understanding of wooden ship building and the interpretation of shipwrecks and archival material.
Words set in bold type are defined elsewhere in the glossary. Entries have been illustrated wherever possible, either within the glossary or in the text. Alternate terms or spellings are listed in brackets after the entry. Alternate definitions for a single entry are commonplace; this is the result of diffusion, varying localities, and technological progress. However, the reader is cautioned that many of the timbers and devices listed here might have had additional identifications, often the invention of the writer or in local slang; some difficulty may be experienced in identifying such entries in various documents.
The confusion extends to modern publications. One marine dictionary shows the knee of the head as being located behind the gripe, while most of the others call this timber an apron and properly place the knee of the head just below the bowsprit. I have tried to sort out this confusion where possible. A few of them have been assigned terms in archaeological publications; the rest I hope I have anticipated and defined accurately.

The invention relates to shipbuilding and for the design of contours of the hulls of displacement vessels, combining elements characteristic of the contours of single hull vessels and catamarans. At the same time, the advantages of single-hull vessels include the possibility of ensuring high stability in conditions of significant sea waves, the advantages of catamarans – less resistance to movement in water and the possibility of achieving higher speeds.
The disadvantages of single-hull vessels include a relatively greater resistance at high speeds, to the disadvantages of catamarans – burrowing of the nasal extremities into a wave and less stability on a rough sea. Specifically, in the invention according to the specified patent, which is further considered as a prototype, a hull form is proposed that includes close in length single hull bow and catamaran aft ends.
The combination of these extremities into a single hull is ensured by a smooth combination of their outer sides, connecting the inner sides of the catamaran hulls floats of the aft end, separated by a tunnel, to the end bulkhead transom of the single-hull end and the deck above the tunnel between the catamaran floats. The border of the contour transition between the bow and stern ends is located near the middle of the length of the hull of the vessel, while in the bottom part there is no smooth transition of contours – the rear part of the single-hull bow end is limited by a bulkhead, behind which the tunnel between the floats of the catamaran stern end begins.
In the lower part of this bulkhead, in a substantial part immersed in water until the vessel reaches a certain speed, there are exits of the channels of the ventilation device through which air is supplied during acceleration of the vessel to reduce resistance to movement in water. According to the applicant of the said patent, the use of such a hull allows to improve the characteristics of the vessels under all conditions of sea waves, in particular, in relation to achievable speeds compared to single hull vessels.
Despite the fact that the description of the invention according to the patent US indicates a special case of its presentation, from this description, drawings and the claimed formula, including from paragraph 1, it follows that the proposed hull form is designed for high-speed vessels, primarily boats, the main design mode of movement of which is the planing mode. It is this effect that is used in the housing proposed in the patent US , the single-hull nose end of which, in accordance with the claimed formula, is provided with a V-shaped cross-sectional shape having a number of fractures cheekbones in order to lift from the water due to dynamic support forces at a certain speed and ledges longitudinal redans and characteristic for planing boats.
A single-hull nasal extremity with a transverse bulkhead bounding it, which is substantially immersed in water during acceleration of the vessel before transition to the planing mode, moves in a displacement mode, having contours that are not optimal for this mode. In this high-speed mode, the fore end of the hull has a resistance that does not allow the vessel with the proposed hull to have any advantages compared to traditional single-hull vessels. To facilitate the lifting of the single-hull nasal extremity from the water and the hull exit to planing, in addition to giving it boat contours, in paragraph 1 of the claims of the patent US also states that:.
Without the specified ventilation device, the necessary acceleration of the vessel is practically impossible or substantially difficult.

They had a visit from a goliath grouper they named Spot as he made himself comfortable under Running Erins for their two-night stay on the historical island.
Part of the fun of doing the loop for Ron and Erin was the cultural, historic and culinary experiences. There were many wonder-filled experiences including exploring historic sites and enjoying fabulous dockside meals from pizza in New York City and Chicago, to prime rib at the Coinjock Marina and Restaurant famous for its ounce prime rib in North Carolina.
Throughout the trip Captain Ron and Erin would host family and friends while meeting new friends including fellow Loopers. Instant bonds were created from their shared experiences.

MATTs are an important part of the training activity carried out by every officer and soldier in the British Army, regardless of whether they are part of the Regular Army or Army Reserve. MATTs are divided into nine sections and cover a range of subjects considered important to the profession of soldiering, focussing on skills and attitudes that contribute to operational effectiveness. These subjects include shooting, fitness, first aid, navigation and operational law amongst others, and individuals have to achieve and maintain a standard appropriate to their role and their likeliness of operational deployment.
This article is divided into seven parts for easier reading. Part One provides a background to MATTs, discusses what they are, and when and where they are delivered, as well as a brief history. Part briefly describes the responsibilities of commanders and training officers. Part Six outlines some of the benefits to employers of officers and soldiers who have undertaken MATTs training. Finally, Part Seven provides some useful publications and references.

The present invention relates to a marine speed nozzle which is positioned around the propeller of a ship and is hydrodynamically structured so that it maximizes the thrust provided by the propeller at lowers speeds, while also increasing the free running speed of the vessel. The most common propulsion mechanism used for cruise ships, tankers, freight carriers, steamships, cargo vessels, loading barges, tugboats, and other large marine vessels is the radiating blade propeller.
The propeller, which basically is a hub surrounded by a plurality of fan-like blades, is typically located under the rear or aft end of a ship and its rotation accelerates water towards the rear of the ship to effectuate the primary means of driving and maneuvering the vessel. Those skilled in the art relating to marine propulsion devices have realized that the propulsion efficiency of a ship’s propeller may be increased by carefully channelling the incoming water flow to a ships propeller and similarly directing the accelerated water flow efficiently as it leaves the back of the propeller.
In the past, various types of conical enclosures or nozzles have been fashioned in an attempt to increase the performance of the ships propeller.

A point beyond the mid-point of a ship’s length, toward the stern relative to an object or point of reference ‘abaft the fore hatch’. Further aft than the beam: a relative bearing of greater than 90 degrees from the bow: ‘two points abaft the port beam’. Some modern references claim that AB stands for able-bodied seaman as well as, or instead of, able seaman. Able seaman was originally entered using the abbreviation AB instead of the more obvious AS in ships’ muster books or articles.
Such an entry was likely to avoid confusion with ordinary seaman OS. Later the abbreviation began to be written as A. The correct term, able seaman, remains in use in legal documents, in seaman’s papers, and aboard ship. An Able Seaman also AB is an unlicensed member of the deck department of a merchant ship. An AB may work as a watch-stander, a day worker, or a combination of these roles. On or in a vessel see also ‘close aboard’. Referring to cargo being put, or laden, onto a means of transport.
