They say that success breeds success, and that is certainly so in the case of this register. In just six years it has established itself as the first, the best and the only illustrated register for the world’s dredging fleet, and essential reading for anyone involved or interested in this dynamic business. Now in its fourth edition it is better than ever, incorporating more vessels and expanded specifications, performance data and a vital new industry directory section. This has been made possible by the participation of the IADC (International Association of Dredging Contractors) and many of the best known dredging contractors, all of whom have recognised that it is in the best interests for the industry to have one definitive reference source. For our part, we used our expertise as publishers, researchers and compilers to make this simply the finest register of its kind ever.
