    Nice work, Ecofeco. It looks very precise. I hope you'll make the entire cat. We can make it into a render competition then ๐Ÿ˜„
    btw Sang really gets to go places, doesn't he? ๐Ÿ˜„

      Okay, NOW you all can start telling me what I doing wrong. ๐Ÿ˜„ (because I know I am)

      I'm also thinking about making this sail instead of fully motorized, so the thruster you see is mainly for channel/harbor maneuvering.

        Any suggestions? Obvious mistakes? I think I have the rudder and thruster misconfigured or designed wrong.

        Does anyone see any glaring errors?

        Thanks.

          Hi Eco, nice looking Hull there, I would suggest removing the Kort nozzel as ive never personaly seen one on a Cat before,or such a small one, but your rudder assembly looks fine.

            Ah! Thanks!

            Is there something else that can be used for channel and harbor? A small standard prop perhaps?

              Well your size Cat suggests it only needs skill to moor,im pretty sure larger cats have bow thrusters but if you say is there anything else,im assuming you made that Kort nozzle with the idea that it was a azipod?

                Well I blew it. I've realized the scale is all wrong. And the way I constructed it, I'll have to start over. And the deck railing is overdone.

                At least I can save the rudder and forward top hatch. And I know what I'm doing this time around. Which ought to mean better geometry as well.

                Live and learn.

                    ๐Ÿ˜† Right?

                    As with my other exercise models, I only have what I can find on the Internet to work with. Which is fine. It makes me work and focus on the numbers instead of just free-flowing.

                          Preliminary setup. Still need to scale all plans to each other.

                              I just search google. Sometimes I have to search a lot and even then, I often have to settle for the next best thing of what I had in mind.

                                  Roughing in the bulkheads. I have just one bulkhead to go by, so I'll have to fake the rest.

                                    Going to be a lot of adjusting before I skin. The hull profile slopes from the top middle down to the ends.

                                    I had to pick this one, didn't I? ๐Ÿ˜† Oh well, it will look more interesting this way.

                                        Most of the bulkheads placed and now to just refine their profiles and set up the final aft bulkhead, then find the true hull curve.
