Really. The Class should have a discussion about where they want to go - it would be nice if the boats are more durable and built in a more worker and environmentally friendly way, but that’s a discussion that should be had held with all of the stakeholders in the class including the builders, all of them.
In the meantime, these boats should be taken back and the buyers’ monies refunded. An institutional buyer can probably be found for these boats who can benefit from their strengths and not affect the other participants in Class racing. Hopefully the builder is willing and able to make this happen.
