The heel-induced sway force and yaw moment of a high-speed craft in following regular waves

The coupling between heel and the loads in the horizontal plane is usually neglected in manoeuvrability studies. However, the heel–sway and heel–yaw coupling can play an important role in potentially unsafe conditions, such as in a following sea. In these conditions, small fast vessels experience dynamic instabilities which threaten their...

The manoeuvrability of high-speed craft in the following sea

Broaching-to is a highly complex, non-linear dynamic instability event that several vessels might face when sailing in the same direction of the waves, for example when returning to port during a storm. This condition is referred to as following sea. Vessels such high-speed craft but also patrol and rescue boats, fishing trawlers or small...

Experimental and numerical investigation on the heel and drift induced hydrodynamic loads of a high speed craft

Heel-seeway-yaw coupling hydrodynamic loads on a high speed vessel

Experimental and numerical investigation on the heel and drift induced hydrodynamical loads of a high speed craft

In order to provide an insight into the manoeuvring of high speed crafts, an experimental study was undertaken at the towing tank of Delft University of Technology, using a rescue vessel of the Royal Netherlands Sea Rescue Institution (KNRM).<br/>
