Sažetak
The method for lightship weight prediction of small craft, developed in previous work, is upgraded after additional data for several aluminum and FRP hulls become available. Practical parametric equations for weight prediction are developed from the database, while the quality of these equations for lightship weight estimate is tested by the vessels from the second database (containing craft with only lightship weight known). In this way the confidence in lightship weight prediction is much higher. The standard deviation obtained for the lightship estimate is 6, 6 % and 10, 3 % for the FRP and aluminum hulls, respectively. Additional data for the deckhouse weight estimate are provided, since in many cases they are made of different materials form the hull structure and sometimes are even physically separated by resilient foundations. Additional effort was made in order to improve hull structural weight prediction. A midships section was approximated and average scantlings determined in order to find unit weight amidships. A longitudinal structural weight distribution function appropriate for small fast craft was devised in order to predict the major part of the structural weight. Parametric equations for other component weights are adapted based on the previous work published.
