Captain’s Log – Day 30

      We’ve got a crazy last night… Brainstorming with my colleagues on a two big cans of energy drink, gave me the focus I need to draw the last boat parts before the cabin – back stairs and the sails.

      On the end of the night I was almost ready to focus on the cabin and the solar roof. But… Because of the excess of inspiration I had last night, this morning I woke up with an new idea for hull shape optimization… the roof will delay again.

Captain’s Log – Day 27

       We are going social… 

      The Rare Blue Project now have an official name, facebook and instagram pages and ti’s own domain. Slowly but steadily our work become more and more serious. You guys will also be able to join and help us soon, so keep your eyes open for news.

Captain’s Log – Day 26

      Designing the new roof was more complicated than I thought. For enough surface to capture the sun, we need more area, which extends the entire body of the boat. So today was not the day for the roof, but for the body.

      We recalculate all dimensions and extend the hull’s length by 90 cm. But what we did is that we only extended the bows (the front part of the hulls), keeping the center of gravity and the position of the main mast unchanged.  Now the complete waterline length is officially 19.5 m. What we also change was the length to beam ratio to Lbr= 12, reducing the beam of waterline, as well as the draft of the boat. This significantly reduce the drag, highly increasing the performance and the speed of the catamaran.

      Enough changes… Now is time for the roof 😀


Captain’s Log – Day 25

      Hull design is ready. We still need to optimize the shape of the centerboards and rubbers. Also the draft was designed for a boat weighted about 18 tons, which will also be more optimized.

      Anyway, the interior inside the hulls is now finished: four double bedrooms, two bathrooms, two toilets and two storage rooms inside the hulls. More storage is available into the bridge deck, so it is ready to care at least 8 people for a longer travel.

      Now it’s time to design the roof. This will be the most important energy producing part of the boat, because it must include at least 4 KWp of solar panes. Nik, our designer works hard, so soon you’ll see the result.

Captain’s Log – Day 21

      First try to capture some footage for the incoming presentation video. I want to include a moment in a rainy day for a stronger expressing the main message of the project.

      Well, using an umbrella to cover my camera from the rain was not the best idea. Wind blew it away together with my expensive camera and the tripod. But falling on the grass land saved them all from damage, so there will be a presentation video soon 😀

Captain’s Log – Day 17

      “Well done, Mr Paterson”, said one of my colleague who accidentally saw my drawings. “Mr Paterson” came from the name written on our rent house door. About my colleague, Uglesa, he is from Serbia, and for a fact, he is the only one who is curious about this project and actually motivates me to keep going. The others just laughs and ask stupid questions.

      Anyway… 17 days after the start, we are already not only estimated the main dimensions, but also draw the first design. Large rooms, good aerodynamics, and enough place on the roof for 4KWp solar panels…

“Well done, Mr Paterson” 😀

Captain’s Log – Day 15

      I am a night shift again, trying to design the bridge deck. It is really hard to estimate the dimensions properly for the deck compartments to be practical for long time living.

      Nik just gave me some sketches, so I am making a coffee and start drawing… Keep your eyes open, because soon we’ll start sharing the technical data of the project.

Captain’s Log – Day 12

      Step by step we are estimating the main parameters. Now, using 3D is much more easier to change dimensions and get more accurate visualization of what we really do.

     Ouh, I almost forgot – I finally finished  the calculator.  I’ve put all the formulas in a simple program, which is able to calculate immediately everything, when we change an initial parameter.  This makes our life a lots easier taking us a light years ahead on the design. Now, after a few days of crazy research and calculation, we finally get the most efficient cross section for the boat’s hulls, as well as the position of the main mast.

Also for a first time we trying to test the design in “real conditions”, using the latest simulation technology… Well, as you see on the picture, we still have to learn a lot more about this, before we get the real simulation results.


Captain’s Log – Day 10

      Things just got serious…
I am on a night shift in the office, where I have a second screen to attach to my laptop. Also a big working table where I can spread all of my maths and drawings.

      It is now time to draw… to draw a lot. And I am not alone. Two of my craziest friends were willing to join, and now we are working together, bringing the things to life much faster. Also I have a good friend with a lots of sailing experience, who gives a precious advises.

      What about the others? Well I still do not share any information. But, seeing me all the time covered with papers containing complicated maths and drawings, some of my colleagues now start to jog with me… “you will give us a ride with your boat, right?”… I have no words to say about that. I’ve already experienced this, few years ago, on the beginning of the school project for the solar powered car. It is nothing different. Closing my eyes and continue.


Captain’s Log – Day 5

The first handmade sketch is ready. It is nothing special, I just put some ideas on a paper, realizing that I did not draw anything from 5 years…

Normally, I am not good on this. But because of the magical wooden pencil box, a miracle sketch was born…

Still have no idea how big it will be. Simply because I can’t imagine it. I know only that is have to be big enough to be able to travel across the ocean. Tomorrow start with calculations, so stay online for the next update.
