People have always tried to utilize the forces of wind and water to generate the power. The sailing ships and boats of the past used the wind  for propulsion. You should agree that it was quite untrivial task to maneuver a sailing vessel to some destination point under frequently and seriously changing weather, sea and wind conditions.

Moreover, seamen always have to sail through very narrow passageways and through areas with dense traffic. The proceedings of the Eighth Robotic Sailing conference contained in the present publication, have been divided into three major parts. The opening part of the book has been devoted mostly to different technical hardware solutions newly developed for the autonomous sailing platforms - the design and construction, test sailing have been addressed, together with the application of various devices.

The second part is intended to introduce some new ideas relating to the mission planning, localization and avoidance of obstacles. Finally, the last part of this volume is dealing with the design and modeling of controllers and sensors, including their evaluation. Note that some of the papers contained in this collection may treat more than one of the aspects mentioned above.

The publication contains the proceedings of the Seventh Conference on Robotic Sailing which was held in 2014; the volume includes numerous interesting works presented by the researchers from all around the world relating to both future and current challenges in the development of the various autonomous sailboats.

The autonomous sailing robots are the boats that only use the wind force for propelling with neither any actual human assistance nor any sort of remote control. The type of sailing in question offers the great potential of long-term and range autonomous solar, wind- and wave-propelled devices that are also carbon neutral. Such devices would greatly contribute to the monitoring of various important data, for example ecological, hydrographic, environmental conditions and other. Moreover, such robots could also be utilized for monitoring the traffic, assistance, surveillance, security plus rescue purposes.

However, they are still very dependent on the wind and sea conditions that are subject to the rapid change, and this is what in fact presents a serious challenge for the route planning, control of stability and avoidance of possible collisions. We recommend to treat the book as a definitely interesting and also quite informative publication for every robotic sailing enthusiast willing to be kept updated with the very latest technological developments and advances in the subject field.

Though the Robotic Sailing conference held in 2011 was only the fourth in a series of robotic sailing conferences, the organizers of this important event have noticed a significant increase in the number of people working on and interested in the field of robotics sailing. This official publication contains the proceedings of the Fourth conference and was released with the intention to duly summarize the state of the art in this area.

The first introductory part of the volume provides all interested parties with a good review that illustrates the history as well as very latest developments in robotic sailing. It is very important to clearly understand that possessing a reliable and robust boat shall be considered a basic and key requirement - this is what the part two of the book is mainly focusing on. The proposed boat designs are ranging from smaller one-design boat for development of the algorithms to the ships able to sail across the Atlantic Ocean.

Part three of the book discusses some technical aspects of the system design and validation. The other papers that have been included in this part concentrate on algorithmic issues. The remaining parts of the book deal with the approaches applied to collision avoidance, localization and route planning.

The collection of all activities during the STAB 2006 that was held in Rio-de-Janeiro, Brazil, in 2006. It is presented as the small program which requires no installation; it allows to navigate through the structure of the STAB conferences and access all documents.

Among the key points of the subject conference there were IMO and weather criteria, workshop on safety of offshore floating units, naval architecture and stability, probabilistic approaches, fundamental aspects of parametric resonance and parametric resonance in realistic seaway, numerical and physical modeling for parametric resonance, environmental modeling, stability of high speed vehicles and naval vessels, maneuvering in waves, nonlinear dynamics, intact stability and ship motions, damage stability for passenger and naval vessels, ship survivability, risk-based approaches to damage stability, rules and standards, behavior of the damaged vessel and progressive flooding, accidents investigations, stabilizing systems, safety in operations, water on deck etc.

Taking into account the technical freshness and actuality of the materials included into this set of papers, we would definitely recommend it to anyone willing to stay duly updated with the latest technical developments in the field of ship stability.

As long as shipping existed ships were exposed to the hostile environment and shipbuilders from the oldest times learned that in order to survive in this environment ships had to stable. They developed also by the method of trials and errors the practical knowledge how to build comparatively stable ships, however hot stable enough to ensure the safe completion of the voyage.

In modern times understanding of basic laws of ship's geometry and static stability enabled naval architects to make calculations during the design stage, then developments in ship hydrodynamics allowed to calculate the behaviour of ship in a seaway and the effect of external forces on stability. Nevertheless from time to time ships were lost as a result of capsizing quite often with all hands onboard. Even introduction by some nations of stability regulations which also included certain stability criteria did not eliminate casualties.

For more than twenty years IMO have made numerous attempts to establish international requirements for ship stability. The achieving of this aim is now becoming possible because of the latest development of stability criteria, which is one of the most complex problems of ship design and construction.

The series of international technical conferences held with the purpose of improvement of the Stability of Ships and Ocean Vehicles has been running since 1975, and, on behalf of the National Committee, I am very proud that Australia was chosen to host the 7th conference in February 2000.

The objectives of the present conference series is to promote a full exchange of methodologies and ideas related to the stability of ships as well as ocean vehicles. It creates practical opportunities to all marine industry pros, including ship constructors,  naval architects, officers of the various certifying and inspection authorities, regulatory agencies, capsize prevention researchers, ship and platform owners, and others to present, discuss and listen to improvements in capsizing prevention for all sizes and types of floating structures.

The most important aspect of any floating object is its ability to remain afloat and upright under all expected conditions. Even this most basic of requirements can elude professionals in the field, usually with very serious consequences. It is therefore vital that all of us who are concerned with the operation and design of ships and ocean vehicles devote the utmost effort to ensuring they are as safe as possible. Only by sharing knowledge and experience can we continue to improve safety, which is the primary motivation for this important conference series.
