Why are floating breakwaters difficult to keep in position during severe weather?

Floating breakwaters are difficult to keep in position during severe weather because they require extremely massive moorings to prevent them from being torn away. These moorings are not only difficult to install but are also subject to constant movement and chafing, which necessitates substantial and ongoing maintenance.1

Additionally, in areas with a significant tidal range, the moorings must include a degree of slack to function properly. This unavoidable slack can allow the breakwater to ride over large waves, which reduces its effectiveness by permitting a considerable portion of the wave energy to pass underneath it and into the protected area.1
