So I looked into my drawing archive and surfed the www… and I was again and again attracted by the way Ulf Johansson designed and build his Kayaks (https:\/\/www.johanssonkajak.com\/?cat=6) – with my strong connections to Sweden I also put Bj\u00f6rn Thomasson’s Designs into concideration. From my experiences in paddling and as a Naval Architect the lines of Ulf told me, that he is a much better paddler than I am and that his designs are focussing on Seakayak Racing and fast traveling. He features a nearly round main center section. I was not willing to take that risk and aimed out to the more classic rounded “V” shape of the main center section. This shape provides significant bigger initial and secondary stability with not too much additional drag. During this process of conceptual design I decided to not draw the kayak my self and narrowed in onto the “FREJ” from Bj\u00f6rn Thomasson. This design is actually build by Struer Kayaks in Danmark and my daugther liked the look… In the End Bj\u00f6rn and I found an agreement for a customized version of his “Frej” Design<\/a>. He provided me a paper set of drawings and a digital set of the drawings and first license to build one of the boats. He actually “spread” the offering for the “Frej” in a range from “S”, “M” to “L”. I will buy another License for our younger daughter when she is done with her Greenlander… One reason for not drawing the design myself is my study beside my job. I am going to be a “Master in Digital Tranformation”. Means for me Digital Manufacturing is every day job and I apply this not only to my professional life. So I used laser cutting to cut out the cross sections of the new boat. Bj\u00f6rn provided me the DXF\/PDF of the drawings and I prepared his design for my trusted laser cutting company<\/a> (known from my other hobby – Model Rail Road). A few weeks later – yesterday – the package with the cutted sections arrived.<\/p>\n\n\n\n I am quite happy with the results – the Laser Gang and Harald did a good job! All the markings appeared clear and the sections are super precise as expected. Sitting one hour in front of the computer instead of standing 5-8 hours in the shop to cut the sections and produce saw dust is a good trade in for 150.- \u20ac <\/p>\n\n\n\n At least for me and my super tight time budget. I also will employ 3D Printing in plasic and metal for some of the details. But later more on that. Next will be the Strong Back. I will utilize a strong Aluminium profile from special vehicle construction industry to make my life easier and the boat straight. <\/p>\n\n\n\n Today I ordered the Aluminum Tube for the Strongback. I decided to go for a 32mm x 112mm AlSiMgMn Profile suitable for Vehicle Design.<\/p>\n\n\n\n
