I would like to get an idea of the world wide markets for new yachts of the following types:
  1) monohul sailing yacht 
  2) catamaran sailing yacht
  3) power trawler yacht

For each of these 3 types make 10 length ranges capturing the most common sizes sold for that type.
For each type and size range for that type, please estimate:
   1)  average interior square footage
   2)  average selling price
   3)  how many units are sold per year
   4)  total market dollars
