“…30 Based on the reported results in this table, all errors are smaller than 10% except that of Fn B = 1.95 for W1 and W2 hulls. Figure 12 shows the predicted CG rise for planing hull series introduced by Kim et al 31 The displayed plots indicate that the proposed method predicts the CG rise of this planing hull series with good accuracy. As evident in this figure, the CG rise of VWC and VWS models is over-predicted, while the CG rise of VPS model is under-predicted.…”

“…The percentages of error are reported in Table 5 which are smaller than 10% (except two mentioned Fn B ) and signify the good ability of predicting the resistance of the considered boats. Figure 14 shows the predicted resistance as a function of Fn B for the planing hull series of Kim et al 31 The proposed method is proved to have relatively good accuracy at all Fn B for all of the considered hulls. The percentages of error are shown in Table 5.…”

“…Two planing hulls series are considered for this purpose. The first hull is the planing hull series of Naples, 30 and the second series is the planing hull series that was introduced by Kim et al 31 First series is a warped hullform planing hull series and the latter is a spray rail planing hull series. Principal characteristics of these two series are shown in Tables 1 and 2, respectively. In order to evaluate the error of the proposed method in estimating the trim angle, CG rise, and resistance, the formula…”

“…Error in predicting the trim angle of W3 hull is small at Fn B 4 2.5, but then increases and exceeds 10%. The predicted trim angle for the planing hull series introduced by Kim et al 31 is reported in Figure 10. The displayed plots in Figure 10 show good agreement between the predicted trim angles and measurements of Kim et al 31 However, the method under-predicts the trim angle of VPS and VWS and over-predicts the trim of VWS.…”

This article presents a simple mathematical model for predicting the running attitude of warped planing boats fixed in a heel angle and free to trim and sinkage. The proposed model is based on asymmetric 2D + T theory utilizing a pressure equation which is previously introduced in the literature to compute the hydrodynamic force acting on a heeled planing hull. Integration of pressure distribution on the asymmetric wedge sections enables the suggested model to compute trim angle, center of gravity rise, resistance, and heeling moment acting on the heeled planing boat in calm water. The hydrostatic force in addition to two drag forces acting on the pressure area and spray area are also taken into account. Finally, a computational algorithm is introduced to find the running attitude of the heeled planing boats. The validity of the proposed model is examined by comparing the obtained running attitudes for two planing hulls series with zero heel angle and computed lift force and heeling moment of a heeled planing boat against available experimental data. Based on the comparisons, favorable accuracy is observed for both symmetrical and asymmetrical conditions. Moreover, it is shown that existence of a heel angle can lead to a decrease in trim angle and resistance, while it intensifies the center of gravity rise of planing boats. It is also observed that as the beam Froude number increases, the heeling moment of the heeled boat reduces.

Search and rescue operations, especially in ship accidents, require speed and reliability from the rescue vessels in facing the challenges of extreme weather and sea waves. A rescue boat hydrodynamic performance study is very important to be carried out in order to determine the ship’s ability to withstand dangerous conditions while in operation. A combination of using Maxsurf and CFD method are implemented to estimate the resistance of 3 (three) selected designs of crew boat, which demonstrated a good agreement between the two techniques. Selection of the final design also uses seakeeping criteria, i.e. having lower pitching and rolling responses. The final model is further tested in a towing tank belongs to the Institut Teknologi Sepuluh Nopember (ITS) and agrees well with Maxsurf and CFD calculation.
