Individuals with a vision to build a class and make it a success. First you have to persuade people with the money to sell what they have and buy a new boat. Folk can be wary of buying a boat that no one else is sailing - so you have to perusade a few people to go for it at about the same time. Then you need a supply of cheaper used boats to get others into the class - and sometimes this comes from those promoting a class buying a new boat every year or two to create a trickle down of used boats.
