Even IF you had been pesty — and you haven’t been — I’m not likely to loose patience: I take care of both my grandmother (who’s getting surly with age) and a handicapped sister (who’s a twerp).

The “problem” is likely that there aren’t enough corresponding CPs in the curved surface to leave behind a transom.

At this point I’d suggest either ditching the curved surface and create a new face for the transom from the existing CPs on your hull and deck. It will have the basic curved shape you want. Since you’ve probably got a 3rd control edge on this curved surface look to see if any CPs were inserted along it when you did a layer intersection with the hull and deck. If so — and there aren’t corresponding CPs on the hull/deck (you will need to move the curved surface to check), write down those values and manually insert them on the hull/deck before you form any new face … that way you can better replicate the control edge(s) that helped to define to shape of the transom’s curve.

The alternative would be to manually create a matching set of CPs to the hull/deck in the curved surface. Which wouldn’t necessarily be hard (just start by dividing your interior edges and moving the new CPs around to match) — if you do this it may be easier to move that layer a set distance away from the rest of the model so you don’t have problems selecting the wrong CPs on the hull/deck rather than your transom.

The advantage of the former is ease.

Turn on the option to see interior edges, if it isn’t already on, and see if any sort of criss cross pattern of lines has developed on your new transom. If one has AND you can also see it when your view is set to the render mode(s) (if not, don’t worry about it) you will need to break the transom’s control face up by connecting some of your CPs with control edges. Since the transom’s surface was defined with a vertical surface curved in the horizontal plane it is probably best if any control edges you add are as near up and down as you can get. These will break up the face and prevent some, if not all, of the criss cross effect (assuming any was visible).
