As a luxury, the price of second-hand sailing will vary with the changes of years and markets, and its price may be affected by many factors, such as regional differences, various characteristics of sailing and the year of production of sailing. In order to determine the dominant factors affecting sailing prices and explain the changes of sailing prices, Spearman correlation analysis is used. Multivariate linear regression model is established to analyze and determine the weight of the indicators affecting the sailing, and finally get a formula to explain the sailing price. Based on the price model of sailing using ridge regression, ANOVA was used to further determine the effect of regions on different variants of sailing.Considering the consistent effects of different regions on the same variable, a two-way ANOVA was used to identify the inconsistent effects of different regions on different navigation variables.Finally, according to the results of variance analysis, it was found that the price of second-hand sailing varied significantly in different regions, and through two-way variance analysis, there was no consistency between different sailing variants.
