The loading of vessels to secure maximum security and seakindliness is of vital importance to fishermen. This book deals with this important subject in detail and is intended as a textbook for preparing for masters and mates certficates. It also affords practical guidance to the fisheman or smallboat owner. Since it was first published, much of its advice and many of the principles behind its recommendation have become officially adopted, nationally and internationally.
This document introduces some basic principles of the stability of small fishing vessels and provides simple guidance on what fishing vessel crews can do to maintain adequate stability for their vessels. It is not intended to be a complete course on fishing vessel stability. The publication is aimed at fishers and their families, fishing vessel owners, boat builders, competent authorities and others who are interested in the safety of fishing vessels and fishers. It may also serve as a guide for those concerned with training in matters of safety of fishing vessels.
The European zebra mussel in the Great Lakes, a toxic Japanese dinoflagellate transferred to Australia--such biologically and economically harmful stowaways have made it imperative to achieve better management of ballast water in ocean-going vessels. Stemming the Tide examines the introduction of nonindigenous species through ballast water discharge. Ballast is any solid or liquid that is taken aboard ship to achieve more controlled and safer operation. This expert volume Assesses current national and international approaches to the problem and makes recommendations for U.S. government agencies, the U.S. maritime industry, and the member states of the International Maritime Organization. Appraises technologies for controlling the transfer of organisms--biocides, filtration, heat treatment, and others --with a view toward developing the most promising methods for shipboard demonstration. Evaluates methods for monitoring the effectiveness of ballast water management in removing unwanted organisms. The book addresses the constraints inherent in ballast water management, notably shipboard ballast treatment and monitoring. Also, the committee outlines efforts to set an acceptable level of risk for species introduction using the techniques of risk analysis. Stemming the Tide will be important to all stakeholders in the issue of unwanted species introduction through ballast discharge: policymakers, port authorities, shippers, ship operators, suppliers to the maritime industry, marine biologists, marine engineers, and environmentalists.
