When looking at all the choices when buying a towboat, it can get confusing. The best way is to boil things down to the basics with the following formula.
Price x Quality = Value
Now this formula sometimes holds true and other times does not when one factor does not fall in line with the other. The idea being that the boat that does well on both price and quality should be rated high on value but one that skews in either direction then their value should fall.
Don't get caught on options because that would have an effect on price and in the long run probably have a direct corrilation on value. Keep things simple.
If you had to rank towboats on the above formuala how would your list look?
