Boat building and design using autoclaved carbon fibre

[s1st]

A new manufacturer of RIBs has entered the global market, building ribs constructed out of full autoclaved prepreg carbon fibre. This advanced technology is used in the aerospace industry and formula 1 car racing. Pretty cool! eXtreme ribs build sports ribs, Superyacht Tenders and ribs for professional applications.

These boats have the best strength to weight ratio, they are extremely light weight, strong and durable.

"These boats have the best strength to weight ratio, they are extremely light weight, strong and durable."

And are so expensive to build that mostly only governments with printing presses for currency can afford to build them.

Happily as time goes by the cost of the materials WILL get lower , and the newest concept of using light or RF to cure the layup may be cheaper than building an autoclave to cure the hull in.

In the larger sizes its not ready for the home builder , or small shop, although simple accessories is not a problem.

You would think that a company building these boats targeted towards cash-saturated government purchasers could afford to buy an advertisement rather than attempt scammy free advertising on a non-commercial site like this. On Sailing Anarchy, this type of irresponsible self promotion would result in a chorus of "Buy an Ad!".

I see nothing new or innovative in these millionaire RIBs. Pretty, but useless. These things are the Paris Hiltons of the RIB world. Go away Dirtbag.

======================
This isn't Sailing Anarchy and I, for one, enjoy seeing this type of thing.The video was good and the boats look terrific. Of all the boats, especially powerboats, that could benefit from this kind of construction these are right at the top of the list. I think the poster may have felt like I did that this is really interesting and wanted to share that with this community. Assuming that the motive was to sell boats seems off the wall to me.
I don't think that sitting in judgement of a poster(with so little information as to motive) is appropriate especially when the comment is "Go away Dirtbag".

UPDATE: I've done a little more research on this Company: the Technical Directer is Goran Marstrom, builder of some of the most outstanding carbon sailing multihulls anywhere:
http://www.marstrom.com/
These boats are the top of the line when it comes to the "rib" configuration powerboat and Marstrom's involvement is a major coup for this company when it comes to quality and technical excellence. Thanks S1st for bringing this to the attention of the forum!

Yes, I know that some people love looking at boating porn - especially if you can view it for free. But, much like "real" porn it doesn't translate well to real life and real people who have to pay bills, work 60 hours a week and try hard to keep the count down to one wife. It sure would be nice to be able to afford to build something as unimportant as a RIB out of autoclaved carbon - but much like Lamborghini's and Aston Martins it just has no relevance to the average person's usage.

I guess if I were the itinerant spoiled son of a wealthy retired father, without career, wife and children I'd have discretionary money to spend on toys like this. But as a responsible adult, I find this kind of product contemptible. And I find the kind of people promoting it without paying for advertising contemptible. If the original poster's motivation was purely third party excitement about the technology, I apologize. But if he/she has ANY financial interest in the product, my dirtbag comment stands.

I'd rather see a little guy like Jeff at Boatdesign.net get a few bucks from people like this paying to advertise their products, than all his hard work get used for free by commercial interests.

Thread moved from the main boat design (discussion) forum to the Press Release forum which is the designated place for promotional threads and press releases.

Folks that build for Governments have their own advertising magazines and information tanks.

Since they are overpriced for most common folks , an advertisement to us , even free , is a waste of time.

Over the years we have learned to spot the Gov shops to avoid.

A good boat builder may have 1 or 2 folks in the front office and 4-10 folks out back building boats.

The Gov shop will have a dozen in front , all doing paperwork , and a couple of folks in back , actually boat building.

EZ to spot,

This forum is about boat building and design, so I thought it fits well.

Applying the technology of autoclaved prepreg carbon fibre is not a luxury gadget, but an innovative technology to take maximum advantage and optimize the properties of carbon fibre. This brings several advantages.

In the marine industry, and specially ribs, this is kind of unique.

eXtreme ribs build ribs that someone may own and use for life because there is hardly fatigue. This may significantly cut the cost of ownership on the long term.
Because of the optimized power to weight ratio, there are significant fuel savings, and as a result a strong reduction on carbon footprint.
What can be wrong with that?

This is not a commercial story, I'm just mentioning the advantages of this technology and my enthusiasm.

Considering ribs you might be right... but in marine industry it's been around at least a decade..

You are right TeddyDiver,
We should also consider that there are many boat manufacturers who process carbon fibre in the conventional way (vacuum bagged) which does not take optimized advantage of carbon fibre properties. Carbon is not a standard material, the way one processes it makes the difference. A nobel prize was given for the invention of a new -carbon like- material that is even stronger and lighter as grafite (the current carbon fibre). It may be applied on touch screens on mobile phones soon, however building a boat out of such a material is beyond our imagination, maybe as it was for using carbon (grafite) about 30 years ago for construction.

Someone has to take the major step, take the risk and create a high demand so it becomes profitable for manufacturers to change their construction methods. Decrease production cost, and decrease carbon footprint because of the power to weight ratio.
Let's say that the next step would be electric engines. This would need a very light constructed boat, while batteries still are very heavy in weight.

Here's more on these extraordinary ribs:

With Americas Cup thinking going straight out the box, ACRM needs technology to keep up with their progress, everywhere from course changes to safety. Why not turn to eXtreme Ribs in Sweden? Started in October of 2008 by the former owners of TornadoSport (builder of the Extreme 40), eXtreme Ribs went into full swing in 2011 when ACRM ordered 10 RIBs with more tender orders for super yachts such as Ecstasea-Pelorus. Now with 22 orders to be filled by the end of the year, they took over the area of their shop where the Tornado catamaran used to built…and then some.

To keep pace with the AC45s, ACRM needed a medium sized rigid inflatable with handling and speed around the course. With a hull weighing in at just over 600 lbs. and twin 250hp supercharged outboards, this really, really ain’t your dad’s RIB. With all the extras added, this 27’ autoclaved prepreg carbon rocket ends up at just over 2400 lbs., about one-fourth the weight of its polyester equivalent. They went with outboards for maneuverability to tug the engineless cats on and off the dock safely, as inboards have too much torque to maneuver properly in reverse.

But speed and maneuverability aren’t the most important aspect of the design brief. In today’s environmentally conscious world, carbon footprints are discussed before steps are even taken. The carbon footprint for the eXtreme RIB is much lower than a more conventional craft. Since the eXtreme RIB is 100% carbon, at the end of its lifecycle the materials can be recycled into asphalt concrete. Called the Cradle-to-Cradle philosophy, the aim is to ensure zero waste going to landfill or incineration, and it doesn’t stop there. During the use phase, estimating 200 days of use per year (an underestimation in my opinion), the savings of one RIB over an America’s Cup cycle of three years would save an estimated EUR 37,000 (at EUR 1.50/liter) per RIB in terms of fuel alone, with a 60 tonne CO2 emissions equivalent savings over a same size polyester RIB, which equals a 29% CO2 emissions and 43% savings in terms of fuel costs for a 27 foot RIB. According to eXtreme Ribs Carbon Footprint Overview, “Utilizing 10 eXtreme carbon fiber ribs operating for the AC circuit over two Cup cycles would provide a total carbon saving equivalent to the total emissions produced by 126 average families in the UK over a whole year.”

They are currently working on a 12.3 meter (40’) RIB for Cup teams to use for their 72’ cats coming out of the shop next year. -John Casey
