Beautiful looking cat , already !

looks beautiful. I'd love to see this in person one day. Congratulations

Thank You. I hope we will meet us together. The world is not so big. In the future our website: carbonbee.de/ will show where we are.

Endlich mal wieder ein Video von euch. Bin mal gespannt wie der Catamaran fliegen wird....

Wir auch!!

[@johanohrstedt9304]

Love your videos, but it’s much better when you do the voice over yourself. Thanks 😊

[@bojanu7212]

Nice, you like our videos. Thanks. With the voice... it was already the discussion in other comments. The problem still not solved. The main issue is, that subtitle translation on different languages is much better, when we use AI voice. We will try our best to optimise it.

[@DenySmashinton]

I agree that your real voice is much better 😊

[@Kirkster131]

Glad to see another video. The AI is kind of a turnoff. Where it not you guys, I would have turned it off. Glad to see the progress.

[@bojanu7212]

Thank you for the comment. I agree AI narrator is little bit annoying, but speech recognition and translations for the subtitles on other languages are much better. Unfortunately, I noticed that my English pronunciation isn't sometimes good recognised.

[@prokat531]

Hi! very interesting and serious project! May I ask, when you vacuumed the hull, was the die surface made of plywood? Are the main hull walls made entirely of carbon or did you add extra panels to increase strength and reduce weight? What is the minimum and maximum thickness of the main outer hull walls? What is the approximate weight of the catamaran at the moment in the video?

[@bojanu7212]

Thank you for the comment. The answers on your questions are in the description under the video, in my answers to the other comments and in the video number 01. In this stage (video 10) the weight of CarbonBee is ca. 3,6 t.

You can find it on Temu online portal.

How did you learn so much about designing a boat like this, building it and then about how to properly install carbon fiber? Also, is this your first build?

[@bojanu7212]

Kevin and I have academic grad of Masters of Science in Engineering. We possess technical knowledge in the fields of construction, design, materials science, engineering calculations and management. Additionally, Kevin has been racing in regattas since he was a child and has won many of them. Although I worked in a completely different industry with world top biggest companies, than yacht building, sailing, designing, and rebuilding yachts has been one of my hobbies. I also briefly worked for a design office in the yachting industry. All of this forms a solid knowledge base needed for our project.

[@robertlaird6746]

@@bojanu7212 That's very cool. I started sailing when my dad built me a little homemade sailboat before I started my schooling and before I knew how to swim. I started racing Naple Sabots when I was 8 and also joined a yacht club and started taking sailing lessons for about 10 years. I've raced many different boats but mostly small boats but my passion was racing catamarans. My biggest accomplishment was winning a major Tornado catamaran regatta that had well over 100 boats on the starting line. we got four first and one second place. Because of that, I qualified for the Olympics but couldn't afford to campaign because it takes a lot of money to travel the world attending all of the races and you have to have two boats. It's crazy expensive.

[@bojanu7212]

@@robertlaird6746 Wow, you accomplish a lot. It is a pity you couldn't continue your racing career. Stay in contact with us. I am sure we will need experienced sailors with a racing background.

[@robertlaird6746]

@@bojanu7212 I'd love to go sailing with you but am about ready to build a Mumby Cyber 48 so that I can sail around the world like I'm sure that your going to do as well. By the way, I also lived aboard a 165 ft. two masted gaff rigged schooner called TeVega for 11 1/2 months. Now it's called DEVA. I hope that you continue sharing your adventures on KZbin so that we can all watch. It's very possible that we will see each other in some anchorage in the future.

[@robertlaird6746]

I've heard that anywhere the carbon fiber is exposed to the UV rays from the sun that it will delaminate. With that said, I would for sure paint the exterior of your boat and see what happens in the future with the inside sun reflections to the fibers. Did you base the design of CarbonBee off of a beach catamaran. I wish that there was more of a story about what went into the design. I'm also what the light ship weight will end up being.

[@bojanu7212]

Carbon fibres are immune to UV degradation, but the resin that holds it is exposed to UV degradation. The way to protect the carbon fibre laminate or glass fibre laminate is to cover it with the UV protective paint or to apply/add UV stabilisers to the resin. We use both methods. Outside we use white paint (additional effect is low temperature in the sun - black surface can reach over 70° C), inside where we use clear epoxy coating we add UV stabilisers. The answer on your other question: yes our design is similar to beach catamaran, because it has two hulls, mast, sails, ruder and is designed to be light, fast and giving a lot of fun. 😀.With these the similarity is ending. Some of the design parameters are in the description under the video, and at the end of video number 01.

@@bojanu7212 Thank you! Your going to have to do a full overview on everything once your completed with the build.

[@bojanu7212]

@@robertlaird6746 Yes, that is good idea.

[@jackdbur]

You would get a better resin to fibre ratio if you used a wetting out table and squeegee the carbon before laying it.

[@bojanu7212]

Yes, in general we make it on this way and always we use peel-ply. You can see it in detail in our other videos.

[@opcn18]

I do not like the AI narrator. Glad to see progress but I'd much rather hear a human person talking about it!

[@SteinVarjord]

I have to agree. It’s just too smooth. Too “nice”. Makes it sound like a sales video. The cool thing about self build videos is that they’re about real people putting huge amounts of time into making cool stuff. It’s about the people, not the video. The voice is a core part of the authentic story. Replacing it with a plastic voice makes the video much less interesting. It’s also a mismatch between the too “professional” voice and the not as smooth videography. If you hire a professional video team to film and edit, I’m sure they would succeed in making it cool, to fit the voice, but in your shoes I certainly wouldn’t want that, even if I was rich enough to afford it.

[@bojanu7212]

Thank you for the comment. AI narrator is maybe little annoying. I chose it because my English is not always properly recognised and in consequence the subtitle translation on other languages is completely incorrect. With AI narrator is the speech recognition and translation much better.

[@opcn18]

@@bojanu7212 Do you have the option to just do your own narration and upload the script as closed captions? I never found you difficult to understand at all but I understand that computers are bad at that.
