OBJECTIVE Guiding the right measurement of each dimensions Creat a simple formula for GT calculating base on LOA Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015
METHODS directly survey on the same type of vessel to take the dimension of LOA, L deck, breadth of mid ship, and depth 487 units purse seiner, 2008 Analysis Standard Formula : GT = V x 0,353 or GT = V x 0,25 (Vb + V superstructure) x 0,353 {(LxBxDx Cb) + (l x b x h)} x 0,353 Nomura &Yamasaki, 1975 Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015

Relation between standard formula and simple formula Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015
Deviation between standard formula and simple formula d = ~ 0.04 Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015
CONCLUSION 1.GT calculation using simple formula Based on LOA is closer to actual GT, it’s indicated by the value of R 2 = 98% 2. If you want to replicate this formula, you should take a few examples of the dimensions of the vessel first. CONCLUSION 1.GT calculation using simple formula Based on LOA is closer to actual GT, it’s indicated by the value of R 2 = 98%, d = ~ 0.04 = ± 4% 2.
