Racers are driven to improve. A rotomolded cat that anyone can sail on their first day will not challenge people with the racer make up. They will outgrow it quickly. A Rotomolded boat cannot be repaired by owners, can be dented and is less stiff than fiberglass.
It's a big FU to the people that buy the new cats and promote the sport, the racers.
You obviously have never raced Rick White on a wave. What challenges a racer is not the boat it's the competition. It's difficult to sail a wave very well and easy to sail a Tornado very badly. Racers do not outgrow their boats (After all these years they are still finding new ways to make the H-16 go faster). Racers may move on to other classes looking for more performance but it’s not because they have mastered their previous boat.
I would also add that the use of roto-moulded boats by resorts is a great way to introduce a broad audience to cat sailing. Some of them may find their way onto the race course.
