Abstract

6947. Eitzen, J. von. March 19. Trawling-gear. - An otter-board is made up of longitudinal wooden slats and removable cross wooden slats a, b, screwed together so as to form an even surface and chamfered at the front edge. The specific gravity is maintained slightly greater than that of water, closed airtubes or other buoyant bodies being incorporated with the cross slats if necessary. The chains for attaching the towing warp are secured to the board as near the vertical edges as possible, and the net is attached at the rear.
