Invest in the money necessary to buy lunch and beers for the experienced boat guy you need to take with you. Sure the list will help, but it is not the end all beat all answer to deciding your future years of time, money, and energy. As guys, we always think it's funny for a woman to pick a car based on the sheet metal, but when us same guys get near a boat while we have money in our pocket, there is that moment of being "stupid". That guy with you is your safety net. It's worth the beers and lunch to take him.
