Hello Rolf,
Thanks for the input.
The stability factor from the boat will be limited, the righting moment will mainly come from 2 crew in trapeze. Racks extending ca 2,5 from the boats centerline. The boat is intended to be sailed "completely" flat. The keel weight will be to balance the mast but not much more. This together with sail area means it will be fully powered up earlier than a T, but later than an A-cat.(if my calcs are correct).

Kind regards

Patrik
