翻译文字：模型求解结果如图3.8所示，其中单体船和双体船训练集的得分都接近0.95，而交叉验证集的得分随着采样的数量而上升，最好的结果接近0.75。结果可以看出模型训练效果较好，对帆船价格的回归和预测较为准确。

The results of the model solving are shown in Figure 3.8. The scores for the single-hull ship and catamaran training sets are both close to 0.95, while the scores for the cross-validation set increase with the number of samples, with the best result approaching 0.75. The results indicate that the model has a good training effect and is accurate in regression and prediction of sailboat prices.
