We are building "CarbonBee" in Berlin (Marina West). Measuring 15 meters in length, based on our JANU-15 design, full carbon catamaran focuses on both high performance and a well-balanced level of comfort
It's a family project from the design over the construction up to... sailing the catamaran.
Unsatisfied with the offerings on the market, we decided to design and build the catamaran ourselves using state-of-the-art materials and technology.
"CarbonBee" is designed to be a true blue water sailing catamaran, offering a combination of lightness, solidity, power, speed, and safety. Our intention wasn't to create and build any houseboat or a condo-maran.
The aim was also to demonstrate that building a high-tech sailing catamaran can be achieved by amateur builders.
The catamaran's two hulls will each contain two cabins for two people, as well as a shower with a basin and a separate toilet with a basin. The bridge will feature a kitchen, saloon, navigation equipment, and a steering station.
"CarbonBee" will get electric propulsion and possibility of recuperation when going under sails.
"CarbonBee" measures 15 meters in length and 9.3 meters in width, with a draft of 0.5/2.5 meters and a weight of approximately 4 t. The displacement is 6.5 t.

Wir bauen „CarbonBee“ in Berlin (Marina West). Mit einer Länge von 15 Metern, basierend auf unserem JANU-15 Design, der Kohlefaser-Katamaran Projekt konzentriert sich sowohl auf hohe Leistung als auch auf ein ausgewogenes Maß an Komfort
Es ist ein Familienprojekt vom Design über den Bau bis hin zum… Segeln des Katamarans.
Unzufrieden mit den Angeboten auf dem Markt entschieden wir uns, den Katamaran selbst zu entwerfen und zu bauen und dabei modernste Materialien und Technologien einzusetzen.
'CarbonBee' ist als wahrer Segelkatamaran für die Ozeane konzipiert und bietet eine Kombination aus Leichtigkeit, Solidität, Kraft, Geschwindigkeit und Sicherheit. Unsere Absicht war es nicht, ein Hausboot oder einen Condo-Maran zu bauen.
Das Ziel war auch zu demonstrieren, dass der Bau eines High-Tech Segelkatamaran auch von Hobbybauern bewerkstelligt werden kann.
Die beiden Rümpfe des Katamarans werden jeweils zwei Kabinen für zwei Personen sowie eine Dusche mit Waschbecken und eine separate Toilette mit Waschbecken enthalten. Die Brücke wird über eine Küche, einen Salon, Navigationsausrüstung und einen Steuerstand verfügen.
'CarbonBee' wird einen elektrischen Antrieb bekommen mit Rekuperation Möglichkeit beim Segeln.
„CarbonBee“ ist 15 Meter lang und 9,3 Meter breit, hat einen Tiefgang von 0,5/2,5 m und ein Gewicht von etwa 4 t. Verdrängung beträgt 6,5 t.

@bojanu7212
@bojanu7212 10 месяцев назад
Thanks! CarbonBee is extreme light and has very low air and hydrostatic resistance, so we decided that 2x 6 kW electric motors are more than enough. Computer simulation show, we will reach 10-11 knots maximum speed easily... and under sails we can lower the engines and get enough current for Anna's demand 😄.

Funny to find this, I've been building the same type of carbon fiber leg extension for two ePropulsion Pod 6.0. I was just laminating it yesterday! My usage is on a regular outboard electric hydraulic tilt/trim thing on my Seawind 1000. First I made the legs in steel for testing and now I'm redoing them in carbon fiber with an hydrofoil type of fairing around the flange where it attaches. The core is 3D printed ABS, with a carbon fiber epoxy cast foot, blending into a mix of unidirectional and plain weave on the skin.

@AntoineGrondin
@AntoineGrondin 10 месяцев назад
More details, I didn't want to use the ePropulsion batteries because they (1) shut off automatically (2) are pretty heavy in terms of kWh/kg (3) don't support CAN to interact with my Victron GX setup and (4) didn't fit well in the space I had available. So I made a custom battery pack with CATL cells (280Ah) and an ORION BMS. I've been slowly reverse-engineering the code to make the ePropulsion motor controller turn on the regen, but I've stopped working on this recently because my solar production has been more than enough for my needs so far. I might go back to it later, or I might replace the ePropulsion controller with another motor controller that is more "open" to configuration. Or I might put a small ePropulsion battery "in the loop" just to turn on the regen. We'll see! I wish there was more options on the market! But electric propulsion, especially with retractable outboards/pods, is so amazing. I just love it. In addition, when the sun is shining and the battery are full, you start to use your engines in a different manner. There's literally no reason not to run an engine and go a bit faster when the sun is overflowing you batteries. So I end up motor-sailing even though I would otherwise be a sailing purist on a dino-juice boat.

@bojanu7212 10 месяцев назад
@@AntoineGrondin Thank you for the info. I didn't buy the batteries yet. So, I have to consider that what you said. Sure we will have the solar panels too, but on my rough estimation it will not cover our needs. Still I wasn't busy enough with this theme, because I do have still a lot of other issues to solve.
@AntoineGrondin
@AntoineGrondin 10 месяцев назад
@@bojanu7212 how much solar are you planning? I went above and beyond and shoved 2,280W overall on the coachroof top and over the arch, and we have a 10m catamaran. You should be able to put more, depending if you prioritize it or not. Mine is all over the dinghy, keeping it shaded and staying in the shades. But it's ~25kg per panel, not so light. Custom panels can be made that are lighter but I haven't gotten there yet, I just wanted a functional prototype with as much surface area used for solar as possible. I'm considering adding a lightweight diesel genset, like the Hatz 1B50 fiPMG, but this would require some creative designing for the air-flow to account for cooling and exhaust. But it's an incredibly lightweight direct-DC 48V generator that's compatible with Victron. Note that there's an exponential curve to power vs. speed. The curve looks best (to me) around 2-3kW of power, to motor at 4-4.5kts. This is a good mix for me of speed and power. I can do 3kts at 800W. Going fast, for long, with my engines isn't something I'm counting on. Sails are for that, otherwise we just need something to move a bit at a steady pace.

Please post more! How did you get the structural requirements figured out? Is it also something you calculated in your CAD or did you outsource to a structural engineer? I'm interested as I design a cat
@bojanu7212
@bojanu7212 7 месяцев назад
First, thanks for the comment. For the structural calculation I used SolidEdge which has well working FEA module. Without the correct calculation I would not advise to design such complex structures as multihulls. If you do not have experience in this matter I would advise that you design the general shape you like, and look for advise of known yacht designer, which has experience in multis, because it is not only the structural calculation and choosing of the correct material and its quantity , but also it's about of many air- and hydro-dynamic aspects around. Wish you success in realisation of your dreams. 👍

@@bojanu7212 how can weight and displacement be different?
@bojanu7212
@bojanu7212 10 месяцев назад
@deerfootnz To explain simple - displacement is (in ship building) understand as the volume of the water (or their weight) pushed out by the ship, and calculated to the construction water line. It is calculated as the weight of the ship and the weight of the cargo (here: the crew with all belongings, drinking water, fuel, eatables, etc). Weight of the boat is considered as it is empty.

@@bojanu7212 so you are actually talking about lightship displacement versus fully loaded displacement.

@bojanu7212 10 месяцев назад
@@deerfootnz Yes, correct. - Lightweight + Deadweight = Displacement. I use the "Weight" of the boat instead "Lightweight" because it is better to understand for most people and the translation in other languages is correct.
