In the USA, I think the growth has been driven by racers joining the class for the racing and the concept of a light singlehanded, single sail performance boat. We are getting new boats from 4 basic builders.

Class growth is not driven by sailors with a better design idea and the skills to go build it.

We are buying boats that are percieved as basically competitive from a domestic builder group that is really quite small.

Within this box, I can think of Ian Lindahl and collaborators and Steve Clark and collaborators building the LR and DK boats on the edge of design. Vectorworks is building the XJ's and Moreeli and Melvin A series. The exchange rate has put a real hurt on the import of Marstroms and Aussie Flyer's 1 and 2 or anything from the EU.

Future growth requires keeping the existing racers and adding new converts. The cat racers moving from 2 man boats or dinghy sailors are choosing between the A class, the single handed spin boats; F16 and F17 spin classes or the traditional Hobie 17 class.

A revolution in design that fractured the class would really change this growth forcast and the dynamics between the single handed cat classes.

How much interest is there in buidling a flying catamaran class?
