Some of these delays were the result of placing historical accuracy above all else. We do let deadlines slip if we are not confident that our content is accurate. Like the Society, Historical Diver is basically run by a volunteer staff who do their best to bring you an accurate accounting of various topics of diving history from around the world. This sometimes involves translating several foreign languages, deciphering local technical jargon, a considerable amount of editing, and also transforming four different versions of the English language into one. The result is often a mid-Atlantic, mid-Pacific blend of English text. It might be a little unusual, but the criteria is historical accuracy: not competing with Shakespeare. If our printed accounting is inaccurate we invite and welcome corrections which we will publish in future editions. In this edition we are pleased to announce the formation of HDS Canada, who under the guidance of the knowledgeable Dr. Phil Nuytten, will no doubt expose us to that country's rich and varied underwater history. Our friends "down under" at DHS ASEA sent over some historical photos of the divers in the Royal Australian Navy which we are extremely happy to share with our members. Skin Diver Magazine has been working its Editor, and our Director, Bonnie Cardone at such a frantic pace that her regular "Women Pioneers" column missed our deadline, after 15 straight issues, but it will appear in the next issue. Those members with an interest in the maintenance and preservation of classic equipment will be pleased to read about the transformation of the Gulf Coast Working Equipment Group into The Undersea Heritage & Exploration Society, a non profit corporation. This wise move, orchestrated by Paul Shenck and John Hoover, provides the group with a vehicle to acquire and maintain artifacts of diving history. Of equal importance, it provides them with various means to fund their chosen activity while ensuring their diving operations have access to public support. We wish them luck on their new adventure.

The product was an instant success and was immediately accepted in the domestic as well as overseas markets. Products and machinery were gradually developed and improved until the first major leap forward in our production technology happened in the 1970’s and early 1980’s when specially designed, in-house constructed machinery for rotomolding of our buoys and fenders was developed and put into use. Such type of machinery at that time was truly unique in the world of molding buoys and fenders. More recent and even more revolutionary developments took place in the new millennium, by our designing and constructing of the first ever fully automated and robot assisted production machinery, built for molding of inflatable fenders. Ever since the start in 1955, our company has been committed to further expand the range and to further develop, customize and improve the individual products. Today, Polyform ® of Norway can offer the widest range of inflatable buoys and fenders , expanded foam marina fenders, purse seine floats and an extensive range of hard-plastic products for use throughout the marine industry, including aquaculture/fish-farming, offshore oil and gas industry, harbors, ships, marina industry and custom made products also for land-based applications.

  • 1.0 Introduction
    1.0 INTRODUCTION 1.1 MARINE RECREATION AND TOURISM IN HAWAI‘I Hawai‘i hosts approximately seven million visitors each year who spend more than US $11 billion in the state and in the last 20 years tourism has increased over 65% (Friedlander et al., 2005). More than 80% of Hawaii’s visitors engage in recreation activities in the state’s coastal and marine areas with the majority of these individuals participating in scuba diving (200,000 per year) or snorkeling (3 million per year) when visiting (Hawai‘i DBEDT, 2002; van Beukering & Cesar, 2004). Other popular marine recreation activities include ocean kayaking, parasailing, swimming, outrigger canoeing, and surfing. Coral reef areas are a focal point for much of this recreation use, but these areas are also a natural resource that has considerable social, cultural, environmental, and economic importance to the people of Hawai‘i. For example, the state’s reefs generate US $800 million in revenue and $360 million in added value each year (Cesar & van Beukering, 2004; Davidson et al., 2003). These reefs are also important for local residents, as approximately 30% of households in the state have at least one person who fishes for recreation and almost 10% of households also fish for subsistence purposes (QMark, 2005). As popularity of Hawaii’s reef areas continues to increase, demand for access and use can disrupt coastal processes, damage ecological integrity of reef environments, reduce the quality of user experiences, and generate conflict among stakeholders regarding appropriate management responses (Orams, 1999). As a result, state regulatory agencies such as Hawaii’s Department of Land and Natural Resources (DLNR) are faced with a set of challenges that include determining use thresholds and how to 1 manage and monitor use levels to ensure that thresholds are not violated, protecting reef environments from degradation, and ensuring that user experiences are not compromised.

OF MECHANICAL ENGINEERING, AIMS COLLEGE OF ENGINEERING, AMALAPURAM. 2ASSISTANT PROFESSOR, DEPT OF MECHANICAL ENGINEERING, AIMS COLLEGE OF ENGINEERING, AMALAPURAM. ABSTRACT-Composites materials are finding wide spread use in naval applications in recent times. Ships and under water vehicles like torpedoes Submarines etc. Torpedoes which are designed for moderate and deeper depths require minimization of structural weight for increasing payload, performance/speed and operating range for that purpose Aluminium alloy casting is used for the fabrication of propeller blades. In current years the increased need for the light weight structural element with acoustic insulation, has led to use of fiber reinforced multi-layer composite propeller. The present work carries out the structural analysis of a CFRP (carbon fiber reinforced plastic) , (Graphite fiber reinforced plastic ), Nibral propeller blade which proposed to replace the Aluminium 6061 propeller blade. Propeller is subjected to an external hydrostatic pressure on either side of the blades depending on the operating depth and flow around the propeller also result in differential hydrodynamic pressure between face and back surfaces of blades. The propeller blade is modelled and designed such that it can with stand the static load distribution and finding the stresses and deformation, strain, for different materials aluminium, Nibral and Graphite fiber reinforced plastic ,carbon fiber reinforced plastic materials.
