Long spines with appendages
Spines are generic to a number of wave energy devices . Ducks use round spines with very low freeboard. Other devices use spines which are, for example, rectangular in section, or have higher freeboards. This report describes experimental investigations into the effects of adding appendages to the Edinburgh spine model. Some appendages were constructed to be similar in section to other devices, some were chosen because they were hydrodynamically interesting.
