Otter boards are used for other fishing gear as well (Brandt, ). Tn the line fishery they are used as either lateral or downward shearing devices. In the Stow net (Brandt, ) of the European rivers a single board is used. GENERAL PARAMETERS IN THE DESIGN OF OTTER BOARDS. Details Big Jon Otter Boat Planer Boards are a revolutionary new planer that out performs the old fashion boards. With this new design, the Otter Boat minimizes resistance while traveling through the water resulting in an increased tracking distance from yourboat, handles well in rough water and does not stall in turns. For superior performance in all water conditions, the Otter Boat is the. heavy shoe to prevent the otter board raising off the ground and to provide stability. Otter board dynamics The basic parameters which have a bearing on the performance of the otter boards are. Angle of attack: The angle at which the otter board is presented to flow of water. Heel: The inclination of the plane of the otter board from the.

  The main parameters describing the hydrodynamic performance of otter board are lift coefficient C l, drag coefficient C d and lift-drag ratio K, whose calculation formulas can be described as follows: (3) C d = F d / ( ⋅ ρ V S 2) (4) C l = F l / ( ⋅ ρ V S 2) (5) K = C l / C d where ρ is the fluid density, V is the velocity of the. Big Jon Sports offers the most advanced design in planers on the market! The Otter Boat is a revolutionary concept that employs improved hydrodynamics. The Otter Boat will gain greater distance from your boat than the old fashion boards and skis and will not trail as far behind your boat as they do.   1. Introduction. Otter-boards are an important part of fishing gear for the spreading of a trawl. The merits of the hydrodynamic performance of otter-boards can be measured using the lift coefficient of the otter-board, the drag coefficient of the otter-board, and the pitching moment coefficient of the otter-board (Mellibovsky et al., , Sala et al., , Shen et al., , Takahashi et al.   I have also heard mixed reviews on otter boards diving in heavy seals, where I never saw that with my super skis. But I liked that in calm waters, otter boards seemed to swing further 75 degrees out to the side, then the super ski’s that sat at more of a degree angle from the stern of the boat. Speed and wave dependent.
