Can anybody share some advice or their experience with running kites on 4.9s.

These boats were never designed for them but many people have fitted kites to them even just for fun outside class racing.

Are the boats structually sound enough to take the kite?
What are the potential problems to look out for?
Have any sailors had any bad experiences with them?

More specifically, is the front beam and the bows up to the job long term in testing conditions?

I have heard of front beam breakages but have also heard of non spin 4.9s with front beam breakages also......

Anybody experience breaking front beams, and if so, what was the cause.
