The heart of our classification organization, ABS Rules and Guides are derived from principles of naval architecture, marine engineering and related disciplines. Currently, ABS has more than 200 Rules, Guides and Guidance Notes available for download. You can search the complete current collection of ABS Rules and Guides below, or for older publications, search our archived database of ABS Rules and Guides.

When printing an ABS Rule or Guide in Adobe PDF format you may experience difficulty if your printer does not recognize Adobe PostScript. All modern desktop printers are PostScript compatible. Some network printers are not. If you experience difficulty, please contact your IT department or download the necessary driver from the Adobe website.

In early 2019, all of the HiTechnic downloads migrated to the Modern Robotics website. However, some of their important programming blocks were lost in the transition. I provide them below for your use.
Note: The PDF building instructions for this model are a work in progress and will be done soon. In the meantime, this link allows you to download the LDRAW CAD file. When opened in LDCAD, this file shows you how to build the robot in ordered chunks. It is a better alternative to LDD.
Thousands of landing craft were used to transport men and equipment across the English Channel on D-Day. Many different types of craft were used. These ranged from tiny Assault Landing Craft to huge Landing Ships. Other landing craft were fitted with guns or rockets. There was even a 'Landing Barge, Kitchen' to prepare food for the troops. The use of landing craft meant that the Allies could land troops and heavy equipment, such as tanks, on strongly defended beaches that were not previously intended to receive supplies. Because equipment could be brought directly onto the beaches, the landing craft were also a short-term solution to the problem of securing the harbours and ports that were needed for the immediate build-up of men and materiel. Although the development of specialised landing craft began early in the war, it was only on D-Day that they were used on such a scale.
These unusual vehicles played an important role on D-Day and throughout the Battle of Normandy. The failed raid at Dieppe in August 1942 exposed how difficult it was to land armoured vehicles during an amphibious invasion and to break through German coastal defences with insufficient armoured support. As a result, armoured vehicles were designed to perform specialist tasks and reinforce ground troops on D-Day. These vehicles were nicknamed 'Hobart's Funnies' after their inventor, Major-General Sir Percy Hobart. They include the Duplex Drive (DD) 'swimming' tank, like the one in this photograph; the 'Crocodile' flamethrower tank and the 'Crab' mine-clearing flail tank. Although the Funnies had been used in simulation and training exercises, they had not been tested in combat until D-Day. Modified vehicles known as AVREs (Armoured Vehicle Royal Engineer) were created by adding specialised devices to tanks. One example, the 'bobbin' carpet layer tank, laid reinforced matting on sandy beaches so other vehicles could drive across the soft surface. 076b4e4f54
