Shaping ships blocks

Hi there
We’re making a series of ships’ blocks at our boatyard and want to mill the pieces on a CNC machine. I’ve shaped one side of the block using sweep 2 rails and capping the ends but don’t know if it’s the best way of shaping it or whether it will run into problems when the CNC machine has to deal with it. Any tips?

Without having the file, it’s difficult to say. But I would contemplate ‘remove knot’ near the symmetry plane.
