    I belive a 55M catamaran are always bigger than your small 50 cats..Do you have any experience in 50M+ catamaran design ? Have you ever dreamed designing a catamaran in this size one day ? I also expect that you have ability and chance to do so ,I think It makes sense to us whether art or design or concept or order project ...

    About the anchor ,Can I move them from bow to aft ? This is the first time you have see this idea of anchor arrangement ?bad idea or good innovative design ? Thanks for your comments..

    I think You should try doing small cats first, say 18' would be good to start - design, build and test it. Jumping into superyacht league with zero experience gives very little chance for Your projects.

    Anchor location - if You ever anchored on a catamaran, You will understand why Your idea will not work. There are many practical reasons why one should not do this.
    Any boat designer should have seagoing experience, otherwise this is just 'work of art'.

    I know Anchor location of small cats are at the bow, Maybe you've never seen a cat with aft anchor ? But some big cats not at the bow , really at the aft !
    Can you explain why it will not work ?

    I saw/designed/operated many boats with different anchors. I also own power cats for many years thus have have expertise how to anchor them, also on strong current.
    Aft anchor is not bow anchor. When You position the boat head to wind/waves (which is what everyone want), You use bow anchor.
    On Your sketches, anchor is not at stern, it is deep in tunnel between the hulls. It will hold the boat exactly side to wind/waves, and one would not be able to control boat's position - no access for bridle, etc. Add current, and the anchor line will go under the hull, and probably catch the propeller and rudder.
    Another problem, anchor should be accessible and visible - it might catch some objects, lines, etc. so the crew should be able to clear the anchor out. In Your design, there is no access and the anchor is not physically visible.
    In Your design, anchor pipe is close to waterline, is it a downflooding point? If not, where does it go, to watertight deck?
    ...
    One should understand such basics prior to attempt designin 50m boats! This is the issue of nautical culture that does not exist on such artwork.

    PS You could have put anchor on top of mast. Very innovative and nobody did that before. With the same level of usability ;)

    your comment is right . But in fact the hull tunnel is 2.1M Above water so the anchor pipe is not so close to the waterline as your view. so I do not think there is downflooding point. The anchor is far way from the propeller about 8.5M and propeller is 1/2 width of the hull beam . so I think the anchor line is hard to catch to the propeller and rudder.
    I should admit the anchor not at the good location, but for reduce the load to the bow and leave the space for dinghy storage. So have to move to the new location .

    When the boat is anchored on current and wind at different angles, the chain will go at oblique angle one can easily catch the propeller. Imagine the wind of 15kts and current 1-2kts, 90 deg to each other - how will the boat position? On a cat, if the anchor chain attachment point is a bit deep in the tunnel, the chain will go under one hull and damage it. With Your layout, it will be much worse...

    What I suggest: look at working together with proper naval architecture office. Don't design boats on Your own, You will never sell such designs.

    You would think that the "Senior" guys would be encouraging... but that is not the case in the real world... our ego's are always bigger than we can see from our own perspectives... from the inside, we know best, but from the outside we're just fat headed and prideful... this is a fact in this day and age. Internet make everyone an expert... see, even I can become an expert on becoming an expert! I'm not a doctor, but I can play a doctor on the internet! (psychology doctor to you, thank you!)... LOL!

    Everyone should just help each other live their dreams... what every that dream may be. I think that TZ3dcom did a great job and have a gift... Not everyone can invest that amount of time and create something as cool and beautiful as what he has done.

    I would get him to model my projects... I don't have the time to waste on making pretty renderings... I am an engineer and I know the efforts needed to make such a detailed model. TZ3dcom did a ton of work and it shows... Good for Him... let the haters hate, and just ignore them. TZ3dcom has a bright future ahead of him at his pace... He could turn out to be the guy who designs the next big thing... you never know.

    Agree that he could design the next big thing. The next boat (big or small), that floats correctly, is another thing that I would not dare to say. But I want to encourage him to continue on that path. For what he has shown us so far something like 10% (this figure is dicutible, I admit) of what is necessary to design boats he already has it.

    I don't disagree, but here is my point... What he has already done is ten fold what a lot of people here could never do. Give him time and the drive that he has, as displayed in his work, he will be ten fold better than most people here on this site. Just a thought. You never know what is in the head of someone else. Maybe he has a doctorate degree in structural engineering and he is just out of college and this is his first stab at boat design. Maybe he is just playing because his real job is designing something on the micro scale and this is a release for him. it's not our job to judge his motivation, but to answer simple questions to help and encourage. To tell him that his work is only 10% of what is needed, is wrong... You have to have the idea, you have to have a starting point... you need something real in order to move forward, or your just coping what others have done. He is 90% toward something viable, which is more than most will every dream of nor create, as he has.

    Did you see the work that he did? I would not prejudge anyone who is committed to put the time and attention to detail as he has. He may be your boss one day... Just my thoughts out loud.

    Thanks...

    I did not say that, I said that it is 10% of necessary to design a boat. I know very well what I'm talking about. I did not say that he is not capable of designing a boat, I said that, because of what he has shown us so far, he has a long way to go to design a boat. Obviously, I am not able to guess the knowledge that this man has. I can only judge what I see and, from what I see, I have to say once again that a nice render does not mean that it is a boat. At the moment it is nothing more than a decorative object to put on a table. I am not capable of doing such a nice render but I am capable of designing boats and I have been demonstrating it for a long time and there are many projects that endorse me. I do not want to discourage the OP, on the contrary, I recognize the beauty of his render and I encourage him to continue working on everything he needs to become a boat designer. Moreover, if I can help him in that regard, I will be happy to do so.
    In my comments there is no hate, absolutely no (why should there be?), there are only advices derived from the practice of a profession.

    P.S. By the way, review, if you feel like it, the thread: New to site, design and looking for perspective!? https://www.boatdesign.net/threads/new-to-site-design-and-looking-for-perspective.57683/

    you are absolutely right. As a Naval Architecture and marine engineering student and also as a novice designer i feel like ı need more courage than knowledge.

    Well, I will not say that you are not right, the demonstration is in your hands. Try to do something, which you do not know how to do, with much courage and then try to do the same after learning how to do it. I look forward to you telling us the results of your experience.

    You're welcome, man. I will say again that I am at your disposal if you need something (within my means), either to increase your knowledge or to increase your courage.
