Inventions Shaping Our Oceans: Rafnar Hull

By Ariadne Dimoulas– This short article collection will certainly check into creations forming today’s seascape. How has our seafarer background caused today’s groundbreaking creations? Which creations straight our future? What is the stimulant for these creations, indicating what is the crossway in between a certain location as well as specific individual that triggers such an advanced stimulate? Finally, we will certainly have a look at the tale of a certain development forming the aquatic globe today with significant repercussion for tomorrow.

There is a stating “necessity is the mother of inventions”, yet specifying the stimulate of a development as an easy human or social requirement does not totally define what a development is, or its location in humankind. When we think about today’s watercrafts, airplanes, trains, vehicles, phones and so on it appears apparent to consider our varieties contemporary presence is feasible just due to creations. Perhaps much less apparent are exactly how creations in systems such as farming as well as tank farming have actually formed what we consume. Inventions in microscopic lens formed our understanding of illness transmittal as well as consequently enhanced our long life. Inventions in water transportation from Greeco-Roman aquifers to contemporary drain systems have actually affected the advancement of neighborhoods right into a globe that currently flaunts 31 mega-cities, on a trajectory of 41 megacities by 2030, where a huge city has greater than 10 million citizens.

Many times creations can be developed via the mixing of requirement, knowledge, as well as scenarios. Arctic ship advancements as well as enhanced ballast water therapies might be thought about instances of creations produced from cross-disciplinary reasoning driven by brand-new possibilities. Scrubbers as well as scrubber adjustments for delivery exhaust seem creations driven by transforming plan producing requirement. For this very first short article, allow’s study an amazing innovation seen in our aquatic seascape using cross-disciplinary cooperation as well as brand-new believing to get rid of an old issue.

Cruising around as well as pounding versus seas due to harsh weather condition is not secure or pleasurable. Thankfully a service is given birth to in the kind of ingenious watercraft hulls from an Icelandic firm,Rafnar Their turbulent technical innovation in watercraft hull layout might transform our whole seascape market, with ramifications getting to from deluxe watercraft markets to browse as well as save vessels.

One may not typically wish to go cruising in harsh seas, however a Rafnar Hull cleaves via the water also in the roughest problems. The watercraft is constantly planed, as you raise speed you have an impact that the keel is being drawn right into the water causing a sensation that is both regulated as well as nimbly sliding. Bear in mind, this is via massive swells that typically would bang you right into the ceiling of your cabin.

Rafnar’s groundbreaking modern technology Rafnar Hull was developed by a wide reasoning person that started Rafnar, Össur Kristinsson.

Össur Kristinsson was currently renowned for his cutting edge advancements in prosthetic modern technology. Kristinsson is both a prosthetist as well as a prosthetic individual. His firm called “Össur” came to be extremely effective as well as motivational via technologies in silicone lining user interface of prosthetic outlet modern technology, which has actually enhanced numerous lives. As a serial developer, Kristinsson brings the development to a last fully grown phase, after that hands the task over to his commercialization group in order for the development to get to complete market capacity.

Though the Rafnar Hull is not his very first cutting-edge development, Kristinsson had actually constantly had an interest in cruising as well as when he researched in Sweden he came to be specifically thinking about Fredrik Ljungstorm’s round hull. From the success of his prosthetic firm, being currently an upscale seafarer, Kristinsson made a decision to acquire himself a private yacht that has a tender. It was after that Kristinsson understood just how much he disliked being jumped about in a little watercraft as well as questioned why individuals simply approved being jumped about in tiny watercrafts in harsh weather condition?

Out of this requirement, for convenience as well as security in all kinds of seas, Rafnar’s vision was birthed. In enhancement to the globe requiring a hull that minimizes wave slamming, Kristinsson additionally thought it was time a business was called after his better half. Her family members name, Rafnar, was picked as the firm’s name. With Iceland’s Viking marine background, the name additionally fit suitably to the tale of Raven-Fl óki, the very first Norseman to intentionally cruise to Iceland, in 868 ADVERTISEMENT. He took with them 3 ravens to help him in his look for the end up north, as well as the 3rd raven led him toIceland Rafnar appears like the Icelandic word for raven as well as the firm’s logo design is a shape of a raven sliding over the water, its body comfortably matching the distinct contours of the Rafnar Hull.

Kristinsson with his group of marine engineers as well as designers took one decade of establishing as well as enhancing models via storage tank examinations, area tests as well as computational liquid characteristics simulations to develop the end product. During the last 4 years of advancement, from 2011 to 2015, the group worked together with the Icelandic Coast Guard in order to enhance as well as boost the layout with end-user responses. Not just a neighborhood for Rafnar, however the Icelandic Coast Guard are perhaps amongst one of the most requiring aquatic end customers worldwide because of the frozen sea states their watercrafts require to browse in around the shore of Iceland.

To discover more concerning the phases of Rafnar’s change in hull layout, as well as their prepare for the future, I connected to Kar Birgir Bj örnsson, Rafnar’s Director ofBusiness Development Karl formally signed up with the firm in 2016, after having actually collaborated with them on their change right into commercialization.

Karl begins by discussing exactly how Rafnar is entering its following phase of industrial advancement. The strategy initially was to perform beginning of models styles as well as preliminary industrial watercraft structure inIceland Rafnar currently collaborates with industrial as well as develop companions in essential places all over the world in order to have Rafnar Hull watercrafts offered as well as created in your area.

Karl: “We are building strategic partnerships around the world and will continue doing so for the next year and a half to 2 years. The last 6 months have been spent building initial partnerships with boat builders for a future where we franchise the Rafnar Hull design with our new partners. We will continue to develop these relationships and we welcome more opportunities for collaboration.”

“We have already achieved a franchising partnership in Europe. Our strategic partner in Athens, Greece is now operating under the name Rafnar-Hellas, and has already begun taking orders of Rafnar boats, with orders quickly building up. Rafnar-Hellas is building the most powerful Leiftur 1100 to date. Whereas the standard Leiftur 1100 is equipped with twin 300hp outboards, this one will carry three 350hp outboard engines. Our partners in Abu Dhabi specialize in making autonomous vehicles and are working on making a version of our Rafnar boat Leiftur 1100 semi-autonomous. Rafnar and Knarr Maritime Consortium very recently signed a letter of intent to cooperate on manufacturing, marketing and sales of Rafnar Hull and Rafnar Boats in Russia. Operating through Knarr Rus, this moves marks Rafnar’s first steps into the Russian Market.”

“Currently all of Rafnar’s boats are made from fiberglass, however, we do have many requests for aluminum boat builds so we have opened discussions with an aluminum boat builder. Though the curvature of the hull is quite different from a deep v or shallow v hull design, we know that it is indeed possible to build our boats out of aluminum. Due to the numerous requests, we are investigating the potential of having aluminum Rafnar boats sometime in the next two years.”

Will the light weight aluminum develop be as durable as the fiberglass constructs?

Karl: “With the fiberglass vessels, we produce them to be as robust and durable as possible. The same will be true for the aluminum. Though the exact details remain to be seen. Building and testing of aluminum boats will be performed to the same standards as the fiberglass Rafnar boats we have today.”

Without sharing exclusive details, could you provide me a summary of the phases of Rafnar Hull’s development to the development procedure? Were there several mistakes, stumbling blocks, or notable innovations?

Karl: “Initially the design was thought up for larger vessels, originally for yachts. In fact, a lot of the early concept designs were for large yachts, and a lot of pitfalls were avoided in the early stages by then avoiding yacht design and having a RHIB (Rigid Hull Inflatable Boat) be the test platform. There were, of course, many prototypes that were unsuccessful and did not work, but others that showed promise, which became platforms for next stage iterations. Some of the early stage RHIB concepts went into submarine mode. To mitigate this aggressive diving, we focused on developing the bow further to prevent this effect, in the process creating further prototypes. When we felt we had something worth demonstrating to others, we contacted the Icelandic Coast Guard and asked them if they would consider becoming our trial partners. The Icelandic Coast Guard are arguably among the most demanding users around, operating in very rough conditions around the Icelandic coast. Our thought was if they can use this hull to their benefit, then anyone should benefit. Starting in 2011 we began to trial and test various hull prototypes with them. We then continued to make adjustments and improvements based on the Coast Guards’ feedback regarding function, structural integrity, deck plan and layout, and general ergonomics. This partnership carried on for about 4 years until 2015, when we were confident that we had our final boat product, which came to be called the Leiftur 1100, where the number refers to its 11-meter length or 36.5ft long vessel.”

Was there ever before a time when there was severe uncertainty that this brand-new layout would really function?

Karl: “There were of course early prototypes that did not work as intended. It took a lot of iterations and steps with considerable changes that needed to be made. It was a 10-year process of development. Though there were many “back to the drawing board” times, pressing via it inevitably came to be effective as well as what we have today is proof of that. Very at an early stage in screening, it came to be apparent that there was something distinct concerning the layout. So we pressed on as well as remained to enhance the layout.”

I have actually discovered that Rafnar’s owner Össur Kristinsson was influenced by Fredrik Ljungstorm arc-of-circle span, developed for its round arc hull. Although I have actually listened to that this layout, described as a Ljungstorms Sailboat, was unpredictable for hefty weather condition as the round arc hull comparable to a superficial v hull, does not cleave the water well. Though your hull layout cleaves the water incredibly well. How does your advancement got over the regular round hull downsides?

Karl: “While the symmetrical curve and keel were inspired by Ljungstorms design, the Rafnar Hull itself is a completely different design. Aside from symmetry, the only connection to the original Ljungstrom designs is inspiration. Our keel nicknamed the “Cuba keel”, so called since developer Össur Kristinsson had the concept while on a vacation to Cuba, is made for hefty climate problem. It functions forcibly the bow wave in the direction of the rear of the keel, where a low-pressure scenario is produced, drawing the keel back right into the water, lowering as well as alleviating upright activities which would certainly or else bang standard preparation vessels boldy downward.”

Are discharges guideline as well as performance vital to your group? Do you understand any kind of discharge data for Rafnar Hull styles?

Karl: “While emissions are very important, we cannot make any claims that Rafnar Hull boats are more efficient than similar-sized craft, simply due to its nature of wanting to remain in the water, which creates more resistance. Though we have not seen fuel consumption exceed more than 2-3% that of comparable craft, so we are roughly on par. Having said that, we have seen that fleets can become more efficient using a Rafnar craft due to the fact that the average size of their vessels can be smaller. The Leiftur 1100 can be used in operations where the sea state would otherwise call for larger vessels being used, simply due to its unique ability to handle rough seas. As such, fleets needing to operate in poor weather conditions no longer need to be made up of large vessels. The Icelandic Coast Guard, for example, can now use their Leiftur 1100, an 11m vessel, to accomplish fisheries inspections where before they would use 20-90m vessels. Clearly, it is significantly more efficient to use an 11m boat than having to start up and operate up to 90m ships .”

Where can individuals attempt Rafnar’s cutting edge modern technology? Are you as well as the watercraft team touring, if so where?

Karl: “We don’t really tour. Our trip to Maine, USA, came about due to our connection with the New England Ocean Cluster primarily. Also, Iceland has established itself in the region primarily due to the presence of Icelandic cargo shipping company Eimskip. We received a very warm welcome in Maine. Everyone was extremely helpful and supportive, as well as being interested in the boat and the company. It was a very pleasant place to visit and we hope to be back there soon. We do attend boat and industry shows of course, such as the Monaco yacht show and others, but with an increased focus going toward strategic partnerships we will be delegating some of that to our partners.”

“Currently, our demonstrator vessel, Askur, is in the UK and will likely remain there until early next year with our Rafnar UK partner. Until it heads for its next destination, we will, of course, welcome anyone keen to try to ask for a trial.”

“There was a tornado just recently throughout Askur’s remain in Poole, England, as well as waves rose to some 5 or 6 meters (16 to 19.7 ft.). When all the various other watercrafts remained in, we headed out, as we did throughout Askur’s see inMaine Common feeling would certainly inform you not to head out in those problems, as well as good sense would certainly additionally inform you not to do an extremely dogleg in massive weather condition. But this watercraft puncture all that. Each time we head out it verifies itself much better as well as much better. It is really an item of the toughest problems, which’s where it executes finest.

“The maiden voyage and trial run of our other Leiftur 1100 demonstrator, “Embla” was from Reykjav ík, Iceland, to Gothenburg,Sweden The watercraft prepared to go the specific very same day it required to go, as well as it hasn’t had a misstep because. The just upkeep the watercraft has actually needed because it triggered from Reykjav ík in April 2016 was a little bit of work with the blow up collar as well as engines, which just took place after concerning 5000 maritime miles of procedure. She has actually gone throughout Scandinavia as well as to Monaco, where she visited Florida as well as to the Caribbean, back to Florida, after that over to Spain, as well as Greece, as well as at some point to Abu Dhabi, where she is currently. She has actually currently done concerning 6,500 maritime miles on her on stubborn belly as well as has actually preserved her architectural honesty totally undamaged, although she is constantly through various drivers that get the very same guidelines of “drive it like you stole it”.”

This all is quite impressive, as well as I am extremely happy you had the ability to share time to discuss even more concerning Rafnar’s vision. What means could this short article aid accomplish a few of your objectives?

Karl: “Overall, it is simply great that you are so keen to learn more about us and in so doing are helping us to spread awareness of the Rafnar Hull and our craft. We are very often faced with non-believers and those who believe that our claims could not possibly be what we say they are. We look at this as an opportunity to show people what is indeed possible and have done so through both trials and studies. We engaged with the University of Iceland to perform comparison research on the Rafnar Hull and deep “v” hulls, which they did. We lent them a watercraft as well as left them to it. When they were done, they had researches that revealed that the Rafnar Hull pounded on typical 82-95% much less than the deep “v” s they evaluated versus. We like to share our tale as well as its outcome with any person eager to pay attention, which this short article undoubtedly achieves.”
