ABSTRACT:
Drogues are formed in a flat configuration having a central portion and peripheral edges consisting of a plurality of spaced inner and outer intersecting belts or webs which may be separately secured to one another at the points of intersection, or integrally formed, and wherein first supple reinforcements are secured rearwardly of the front surface of the belts along the peripheral edges and second supple reinforcements are secured to the belts extending from edge to edge generally centrally of the drogues so that the drogues automatically open when deployed and are pulled through water. In a preferred embodiment, the central portion of the drogues include a generally imperforate panel.
