The purpose of this study is to </em><em>obtain the </em><em>collision strength </em><em>of &nbsp;the ship that </em><em>can be used as a refrence to determine the </em><em>minimum thickness of FRP lamination. The</em><em> descriptive-numeric method</em><em>s </em><em>were used </em><em>in this research. Some data of the sampled vessel such as vessel type, main dimensions, speed and impact power</em><em> were needed to be analyzed. </em><em>There were 13 sampled vessels used in this research. The result </em><em>showed that the vessel was included to towed or dragged gear.</em><em> The main dimension of the vessel in average were L<sub>oa</sub> 9</em><em>.5 m; B<sub>max </sub>3</em><em>.2 m; D 1</em><em>.2 m with displacement tonnage 13,6 ton/m<sup>3</sup>. The speed of the </em><em>vessel decreased </em><em>since the first collision </em><em>in range of 0</em><em>.4-1</em><em>.0 m/s or 20-75%. </em><em>The </em><em>collision strength on that time was in range of 7</em><em>.13</em><em>-87</em><em>.48 kN<sup>.</sup>m. Therefore, the impact strength that will be used as a reference in determining the thickness of the FRP laminate layer on wooden vessels is 87.48 kN<sup>.</sup>m</em><em>.</em></p&gt;}, number={3}, journal={Jurnal Ilmu dan Teknologi Kelautan Tropis}, author={AnamMuhamad Khoirul and Novita, Yopi and IskandarBudhi H.}, year={2020}, month={Dec.}, pages={747-760} }
