Traditional winches designed for oceanographic research have evolved with several unique features that set them apart from their relatives in commercial applications. Characteristics such as a large drum capacity for long lines, precision level-wind mechanisms and advanced motion compensation systems that maintain line tension in heavy seas have satisfied research mission requirements for greater depths, higher speeds, and improved control and repeatability. But throughout this evolution, the typical winch remains a relatively heavy deck-mounted machine that is powered by the vessel's hydraulic or electric system. This design works well for permanently installed equipment, but it can create operational challenges for temporary installations, and it cannot be used on small vessels.
