    I have installed new version of delftship, just for fun. Nothing like it was so even though an easy model, this was bit of work.This is 12 m long, 3,5 wide, Hogfish like sharpie, it comes almost exactly at 12 tons displacement at 0,7 draft, with keel pulled inside. Why the heck do I have the crease at the end of the deck? :D
    Honestly, boat like this would benefit from a self tacking sailwing and a deckhouse. When simplification, then simplification. Is there any benefit to add V portion to the bottom?

    Can you show the model with deck mesh and control points (control net) visible?

    Is the edge between deck and stern defined as a crease edge?

    Yes. Bu t I think my mistake is to have the transom trapesoidal and then trying to project the curved deck over. You reckon this would be a good build on 8 mm steel base plate? 6 mm sides. Even today prices I can have about 3,50 bucks per pound welded superstructure. :D Build would be a folly though. Boats were never cheap as now as people cannot afford to keep them.

    Ok figured it out, the arched deck needs to be done first and the transom afterwards. The deck gives the box some aesthethics back.

    I cannot seem to get rid of this particular leak point. When attempting to extrude the transom I cannot mark the lower edge yellow. :(

    Doesnt seem to be a bad hull, could it really go at 9 knots on 13 kW? The displacement comes at about 14 ton at 0,8 m draft as with the original hogfish.
