Abstract
The research of vanamei shrimp counting has been developed by numerous scientists, but image processing in actual pond didn’t progress well. The used of image processing based on the way of capturing the image from the shrimp which located on the bottom of the pond. The way to capture the image was to put a camera under the deck of a boat. Catamaran boat model was selected to build a boat that will bring up a camera that will used to capture shrimp image. The Catamaran boat with Loa (entire length of boat body) = 670 mm, Lenght water line (Lwl) = 650 mm, B (width) = 300 mm, T (full/high) = 180 mm, Cb (block coefficient) = 0,55 and Vs (speed) = 19 knots was built to accommodate this matter. The size and specification were chosen to maintain any possibility issue that might happen when the vannamei shrimp monitoring system work.

A vannamei shrimp monitoring system that uses image processing work principles requires a boat which will bear a camera device in the process of capturing a shrimp object in a pool. Physical parameters such as boat dimensions, electrical conditions, speed, resistance, motion, load carrying ability are important aspects in the building process of unmanned mini boat. These parameters further being utilized to the design of unmanned mini boats to be created as camera carriers in a shrimp monitoring system
To get design accurately worked out, we need to calculate each physical parameter precisely (Anonimous, 2001). This boat design will be the main part of the vanamei shrimp monitoring system
Summary
A vannamei shrimp monitoring system that uses image processing work principles requires a boat which will bear a camera device in the process of capturing a shrimp object in a pool. Unmanned mini boat requires several physical parameters that need to be calculated, for instance total boat resistance, boat speed (VS), Volume Displacement, Displacement, Wet Surface Area, Froude Number (Fn), Reynold Number (Rn), Coefficient of Friction Pressure (Cf), Power Efficiency (ηH), Rotative Relative Efficiency (ηrr), Propulsion Efficiency (ηp), Resistance Efficiency (ηr), Efficiency of Propulsion (ηp), Coefficient of Resistivity (Cr), Coefficient of Air Resistance (Caa), Motor Power Drive, Deliver Horse Power (DHP), Propulsive Coefficient (Pc), Power On Axle Propeller (SHP), Main Movement Power (BHP) (Couser, 2000).
