In order to better understand the sailboat market, we have prepared a report on the pricing of second-hand sailboats, considering various sailboat characteristics and economic data divided by year and region. We have followed the requirements of brokers and made efforts to select a more appropriate modeling method. Based on existing sailboat historical data, we collected a large amount of new data and established a model to predict sailboat prices. The regression methods used include bp neural network, random forest, multiple linear regression, svm regression, and decision tree. Based on the mean square error (MSE) and determination coefficient (R²) as indicators to measure the goodness of fit of the regression model, we finally decided to use the random forest method for further modeling.

Secondly, we considered the impact of regional factors on sailboat prices in the model constructed using the random forest method. We discussed the consistency of regional effects on sailboat variants and provided practical and statistical explanations for the impact of different regions. The study found significant regional differences, and the regional effects of different sailboat variants were different. The importance of the price level of the location on Catamarans was much higher than that on Monohulled Sailboats, and personal income and price level also had a significant impact on Catamarans' prices.

Thirdly, we evaluated the application of modeling in the given geographic area, and studied the regional impact of Hong Kong (SAR) on the prices of catamarans and monohulled sailboats in the subset. It was found that sailboat prices were not only influenced by regional factors, but also that Monohulled Sailboats were less affected by local income levels, while Catamarans' prices were higher in high-income areas.

In the following section, our model is accompanied by sensitivity analysis to explain the rationality and accuracy of this paper's model, predict our future work, and specifically explain the advantages and disadvantages. Finally, we have prepared a brief report for Hong Kong sailboat brokers to help them understand the conclusions of this paper.
