The following reasons seem to be of the greatest significance. Breaking waves capsize is relatively rare, and many sailors survive storms by lying ahull or by running off. They do not perceive the need for more gear. There is no firm specification for a drogue. When a makeshift arrangement has been tried it often has not worked and in some instances has made the situation worse.
Prudent sailors are aware that a drogue can impose high loads on the boat.
Since they do not know the magnitude of the loads they are reluctant to take the risk. In a survival storm the crew is of ten tired and disorganized. If the drogue is difficult or dangerous to deploy they are unable to handle the job. The research program described in this report is intended to address these concerns and to provide the information needed to make a rational decision on emergency equipment for the prevention of breaking wave capsize.
