Abstract: A speed reducing device for use from a fishing boat when fishing in a boat moving with the wind and/or a current comprising a rearward portion formed as an essentially circular end panel of water impervious material having the buoyancy to float in water; an intermediate portion formed of a plurality of similarly shaped mesh panels adapted to allow the flow of water therethrough while precluding the passage of debris into the device, each panel having a generally triangular configuration with a rearward edge and side edges converging and meeting at the forwardmost position, the panels being stitched together along the side edges into the general configuration of a cone with the small end of the cone constituting the forward end of the device and with the large end of the cone constituting the rearward end of the device, the end panel being stitched along its periphery to the rearward end of the mesh panels; and a forward portion being formed by the folded midpoints of cords jointly coupled together at the smal
