Underwater lines for a performance cruiser

[Nordic cat]

I have been reading up on some of the literature on hull designs, but there is not much out there regarding cats. So any pointers and feedback will be much appreciated.

By the way this is a bi-rig design without foresails, so I need to ensure easy tacking - so any input on this would be great.

My design has about 52 cms/21" draught without boards. LOA 49'/1490cm

LWL = 47'/1430cm. Transoms are 8"/20cm free of the water at rest. Hull beam is 110 cm/ 3'7". Fineness ratio is 1:13
Prismatic coefficient = 0.575.

Any comments on these figures?

How far back should the max wlbeam be? Also is there an advantage to having the max draught at this position?

Looking forward to feedback from the great knowledge base here.

Regards

Alan
