Problem Y: Understanding Used Sailboat Prices
Problem Y: Understanding the prices of second-hand sailboats
Like many luxury goods, sailboats vary in value as they age and as market conditions change. The attached “2023_MCM_Problem_Y_Boats.xlsx” file includes data on approximately 3500 sailboats from 36 to 56 feet long and advertised in USA, the in SA in December 2020. A boating enthusiast provided these data to COMAP. Like most real-world data sets, it may have missing data or other issues that require some data cleaning prior to analysis. Like
many luxuries, sailing ages Values vary with changing market conditions. The attached "2023_MCM_Problem_Y_Boats.xlsx" file includes data for approximately 3,500 sailing boats, ranging in length from 36 feet to 56 feet, that are advertised for sale in Europe, the Caribbean, and the United States in December 2020. A boating enthusiast provided the data to COMAP. Like most real-world datasets, it may have missing data or other issues that require some data cleaning before analysis.
The Excel file includes two tabs, one for monohulled sailboats and one for catamarans. In each tab, columns are labeled Make, Variant, Length (in feet), Geographic Region, Country/Region/State, Listing Price (in US dollars), and Year (of manufacture).
The Excel file includes two tabs, one for monohulls and one for catamarans. Within each tab, the columns are labeled Make, Model, Length (feet), Geographic Region, Country/State, List Price (USD) and Year (Year of Manufacture).
For a given make, variant, and year, there are many other sources beyond the provided Excel file that may provide detailed descriptions of the features of a particular sailboat. You may supplement the data set provided with any additional data you choose; however, you must include the data in “2023_MCM_Problem_Y_Boats.xlsx” in your modeling. Be sure to fully identify and document the source of any supplemental data used.

Sailboats are frequently sold through brokers. In a desire to better understand the sailboat market, one sailboat broker in Hong Kong (SAR), China has commissioned your team to prepare a report on the pricing of used sailboats. The broker would like you to:
Sailboats are often sold through brokers. To gain a better understanding of the sailing market, a sailing broker in Hong Kong commissioned your team to prepare a report on the pricing of used sailing yachts. Brokers want you to:
Develop a mathematical model that explains the listing price of each of the sailboats in the provided spreadsheet. Include any predictors you consider useful. You may draw on other sources to understand additional features of a given sailboat (such as beam, draft, displacement, rigging, sail area, hull materials, engine hours, sleeping capacity, headroom, electronics, etc.) and for economic data by year and region. Identify and describe all sources of data used. Include a discussion of the precision of your estimate for each sailboat variant's price.
Develop a mathematical model to explain the listed price for each sailboat in the spreadsheet provided. Include any predictions you think would be useful. You can use other resources to learn about other characteristics of a particular sailboat (such as beam, draft, displacement, rigging, sail area, hull material, engine hours, sleeping capacity, headroom, electronics, etc.). ) and economic data by year and region. Identify and describe all data sources used. Include a discussion of the precision of your estimates for the price of each sailboat.
Use your model to explain the effect, if any, of region on listing prices. Discuss whether any regional effect is consistent across all sailboat variants. Address the practical and statistical significance of any regional effects noted
. List price impact, if any. Discuss whether area effects are consistent across all different sailboats. State the practical and statistical significance of any noted area effects.
Discuss how your modeling of the given geographic regions can be useful in the Hong Kong (SAR) market. Choose an informative subset of sailboats, split between monohulls and catamarans, from the provided spreadsheet. Find comparable listing price data for that subset from the Hong Kong (SAR) market. Model what the regional effect of Hong Kong (SAR) would be, if there is one, on each of the sailboat prices for the sailboats in your subset. Is the effect the same for both catamarans and monohull sailboats
Discuss how your modeling of a given geographic region might work in the Hong Kong (SAR) market. ? Select from the spreadsheet provided an informative subset of sailboats, divided into monohulls and catamarans. Find comparable list price data for this subset from the Hong Kong (SAR) market. Simulate the regional impact of Hong Kong (SAR) on the price of each sailboat in your group, if any. Are catamarans and monohulls the same?
Identify and discuss any other interesting and informative inferences or conclusions your team draws from the data.
