How to 3D Print a Performance Catamaran

[@LifeOnTheHulls]

So good to see Aussie builds,bringing state of the art manufacturing back to our shores.Congrats CURE we are all behind you.Ross

[@millanferende6723]

That is awesome! This is EXACTLY what I had in mind when I saw the first boat 3D print from 4 years ago. Would be amazing to see one, with rooms, conduits for electricity and water-pipes, outside benches and any other structures such as pivots or mounting points for solar panels, already in place. You could even make your own custom build boat/catamaran designs!

[@kirkb3473]

Loved the video! 3D printing plastic is actually how I paid for our catamaran, definitely the present and future of manufacturing. Don't be fooled by the outboard helms after day that was a perfect afternoon for a sail! Ask to go back out again on a day when it is raining sideways, blowing 30 knots and you are needing to hand steer while surfing down 2-3 meter waves. Yep, autopilots never break lol.

[@leondaniels4033]

You guys were on an amazing boat that was built by a company that has up to date construction processes that helps keep the price at a reasonable price point. I feel you guys have found the builder that will provide you with exactly what you have been searching for!!

[@TheOKellys]

Yeh, really nice boat. If we had another million to spend, we'd definitely give Cure a shot!

[@BobFirth]

Amazing owners are so reluctant to show their boats that are after all FOR SALE. Especially with youtubers like you guys. What are they so afraid of? So cool to see the future of boat building with your tour of Cure. Your videos are always so informative.

[@fogllama]

I am loving these journalistic episodes. Your documentary film making is a joy to watch.

[@cutekidstories]

Not sure how I missed this one until today, but I LOVED THIS MOVIE. I can't believe how cool cure marine is.

[@TheRaptor1967]

How did I miss this one? Only just seen it now as a youtube suggestion. Looks like I was not getting the notifications. Very interesting. I'm going to be looking for a 55' performance cruising cat in soon (seems like it keeps getting pushed back as I've been looking for almost 2 years now). Manufactured in Australia, ouch. It's great in one way, I live in Australia, but production costs in Australia are as 'Expensive as hell' (at least generally). Very interesting, thank you for the video and information. I'm off to go check them out. :)

[@captainpaddy1524]

Excellent episode. Thank you. Before retiring, I spent a professional lifetime balancing automation versus cheap labor. There is absolutely no doubt: Products made in Western countries, using automation, are a MUCH higher quality than products made in Third World or developing countries using manual labor. They are also more sophisticated and up-to-date. The one problem: The up front capital cost of setting up the automated production systems is really high. So, the investment required to set up an automated facility in a developed country is MUCH MUCH higher than setting up a basic facility in a less developed country; which is why you see so many boat builders in Asia and South Africa. One comment caught my attention: Cure Marine can quickly redesign and recycle molds. That is in complete contrast to many catamaran manufacturers who are using 20 year old molds and everything is done by hand.

[@troybabs]

Wonderful and informative episode. Your filming/production quality is knocking it out of the park. 100,000 Subs is just around the corner! Keep up the awesome work!

[@TheOKellys]

100,000 subs! Wow that's a lot of people! Thank you for the kind words!

[@whitneylake2107]

If you'll excuse the pun - If you've got the (boat) fever, they've got ... THE CURE ! Keep that original music coming ! Awesome episode and thank you again !

[@benjaminperrett588]

Our economy was hollowed out in the 80’s with the move of production to south east Asia so we consumers could have cheaper prices. It has been said that technology will start to bring that back home with the added advantage of strong environmental laws and a social wage. Well done for show casing what the future looks like and welcome to Australia. I sincerely hope you have a great time.

[@timallen6025]

Insightful, I like your approach

[@Canuck_]

Awesome. I love 3d printing technology. I have many 3d printers and I love the ability to make almost anything I want. I also own a 3d scanner so it works hand and hand with the printer. They even have 3d concrete printers.

[@graemepollett1641]

I do love a Schionning. It's on the top of my list while I'm boat shopping. A boat like Zero is waaaay outside of my budget though. Great video guys. Thanks for coming to Australia. If you're coming to The Kimberly's in Western Australia, let me know

[@crustycobs2669]

You guys are pioneering the future. Absolutely brilliant design, and it proved itself.

[@justincase5272]

Well done video, O'Kelly's! Informative and wise.

[@careylogan7639]

On the tech side, this was a monumental video. One of the best yet. I would give this 5 of 5 stars on KZbin University. You guys are GREAT !!!!!

[@zaffman]

Awesome video!! Loved the 3D printing factory tour and seeing the tech. The Schionning was a beautiful boat! It would have been great to get a tour of it as well. If that’s possible can you do a follow up with them? Great content as always.

[@jodymooney255]

What an adventure and experience. You’re truly in your element! Great video too! ❤

[@carsonc1272]

Very cool, thanks for keeping us up to date on the latest boat building tech! It was interesting.

[@hectorcyre7664]

Without question - this is the most exciting episode I have seen yet on the sailing channels I follow. Not just on the O'Kelly's sailing channel. On ALL of them. And I follow a lot of sailing channels. Perhaps for the first time I wish I was much younger, so I could see where all of this goes. No regrets mind you. Regrets are a waste of energy. But the next twenty years and beyond are going to be truly mind blowing. The 3D printing tech applied to industry is going to change everything - from boats to other vehicles to living spaces to food production to anything else you can think of that is manufactured or built in some manner. Damn, I would love to be in the middle of all that.

[@michaelhamilton5571]

Great vid, very informative,thanks

[@bravofighter]

Oh my gosh, watching Zero slip past the other boats at speed was incredible. Nobody chasing sheets, nobody cranking on winches…the owner just casually presses a button and adjusts the sail from the helm. That’s about as close to sailing a Laser as you can get, only your guests are sipping cocktails as you win the regatta, the boat isn’t heeled over, and nobody is getting wet. The hulls just cut the water like a razor.

[@alansmith2203]

That is all fine and dandy near major boating centers like Brisbane. But make no mistake about it Mate....if something goes sideways on ya far offshore and away from major marine centers....you no longer have a sailboat...now ya got a motorized cat. Do I love the concept? Absolutely love it...me nipples are hard just looking at Zero.

[@britboy20002]

When you make it to the Whitsundays, say Hi, I also have a Schionning build in progress in Airlie beach.

[@TheOKellys]

Down in Melbourne now, but will be back end of next week!

[@britboy20002]

[@johngribbin7039]

Great video. The music. The quiet moments. The narration is so…smooth. I’ve been pricing boats too. Trying to decide on speed vs comfort issue. And then it all came together. Something set in. Yeah that’s right…Reality!!

[@CreekRanger]

❤ Impressive Journalism. It is amazing how long it has taken for production boats to adopt techniques that have been used in aerospace since the 1980s I am surprised the catamaran industry has still not replaced foam core with nomex honeycomb. Take a look at a Force Engineering catamaran from the 90s they used nomex core and look like the LongEz of boats almost like Burt Ruttan designed it.

[@exploranator]

Closed-cell foam is still buoyant if it is exposed to/submerged in water/leaks. It is also of similar strength in all directions, so it is well-suited to being machined/cut and placed anywhere it is needed. For those who have never handled this type of foam: it is hard like rock or a hardwood, not like the styrene foam used for insulation or packing material, if I recall correctly. Someone with a 3D printer has invented the lightest strong substance known to man. It is, in effect, 3D-printed foam, but it is open-cell. One of the revolutions of 3D printing is not only scaling it up, but when they can scale it down to cost-effectively print things like closed-cell foam cells/bubbles. Then some phenomenally light and buoyant materials will be able to be created.

[@CreekRanger]

@@exploranator So is Nomex honeycomb plus it is easier to repair and damage is isolated, it is lighter, fireproof and depending on the skins used can even be bulletproof. The US Navy has uses it on specialty coastal ships and take a look at Force Engineering Stilleto catamarans. The weight savings are massive performance gains are unbelievable. I think it may even be cheaper because marine applications are not concerned with number of plugged cells do they can buy aerospace seconds. It is also easy to machine if you know the tricks (10000 rpm jewelers saw 😀)

[@ProjectsinLessTime]

The look on Nick's face while he was at the helm. Missing sailing much?? ;-)

[@davidbauerdorf1324]

Awesome to see you guys out in the wind and happy!!

[@frankmortimer27]

What a great episode, you guys are nailing the content and production

[@LoanwordEggcorn]

3:08 The title is a bit misleading. Cure are not 3d printing the boat. They are 3d printing the plug which is used to make the molds for a conventional, vacuum bagged plastic composite hull. Many boat builders use CNC to mill the plugs currently. While not quite the same as 3d printing, it's also a computer controlled machining process. (Milling is subtractive machining, i.e., taking away material, while 3d printing is an additive process, i.e. adding material. In addition, after printing, Cure will use milling and automated sanding to smooth out the plug.) 17:35 The aft outboard helms are probably better for racing, since as you note you can see all the sails. However for cruising, it's probably not ideal. I still like the Chris White front helms. They're very well protected, keep lines very short, and have visibility of all sails.

[@lassesvedberg6355]

Exactly my thoughts on misleading title. No part of the boat is 3d printed.

[@TheOKellys]

"How to use a giant 3D printer in new performance boat manufacture" is maybe more accurate? Sorry to mislead you. Guys like you know the difference between printing a product and using that print to create a mold. For most of us, we don't. Hopefully it is explained well enough in the video. If you are a longtime viewer, I hope you know we try not to mislead.

[@LoanwordEggcorn]

@@TheOKellys Thanks guys. It is noteworthy that they're using a 3d printer to make the plug. Just getting a bit picky with the title.

I think you can get a 50 ft aluminum Mumby in Vietnam new for less then $600k new.

[@Seafariireland]

Excellent!

[@captainsensible298]

Zero is a most awesome boat, awesome build, but like the man says a VERY expensive pursuit, aramid standing rig is great, not so cheap either. there are other alternative that are more cost effective and more durable for those that want a fast cruiser.

[@juantellez7858]

You spend most of the time cruising on auto pilot. Having the helm outboard gives you the option to see well when you need it. You adjust the pilot see tye saiks, or enter the dock, then go back to the shade.

Excellent episode, forward looking and thought provoking. Sailing is simple at its core, these race boats exemplify that, we cruisers forget it sometimes

[@vbjoker]

That zero cat is really nice 😊

[@robertlaird6746]

Zero is a very cool looking boat but a bit to large and fancy for me. That fancy adds not only dollars but weight. One of the things I've never seen before was that short silver automatic wench. That little disk is cool. Have you thought about getting an aluminum catamaran? If so, check out Sailing Jupiter and Sailing into Freedom. Sailing into Freedom is having a brand new boat designed for him. The prices are very affordable depending on how you do it. Sailing Jupiter has a most popular play list. Watch the most popular one. They go over the price and build.

[@peterpocock9062]

Welcome to Oz you two. It's a great place, as you will learn. Of course I'm not biased, much!

[@barilro]

When you state that you can not have both a fully protected helm and full view of the sails for trimming: a new design brand seems to have figured this out. The Windelo 54 which has a full protected inside helm station with full view of both sails for trimming while at the helm. Check it out…lots of video on KZbin. NautiStyle just did an extensive review.

Well, that was a good one! Cure certainly is up to date amd even ahead of the curve. I liked the piece you did of price comparison as I had little idea of what a 55 footer would cost. Outboard helm is great but can it be made weatherproof? I like the HH 55 in that regard. So more food for thought.

[@222INFINITY]

You guys do such excellent boat reviews, you should be picking up at least $50K for every sale you deliver to the builder. This will also put you on some nice cats to sail. Endless opportunity, the 72 full carbon Chris Whight cats are $9mil, better get the show on the road!!!! Enjoy the adventure.

Thanks for the glimpse into this new technology. Fascinating stuff (feeding my Engineering). Given all this wonderful experience you're getting (whether you like it or not perhaps), I'd be interested in your current thoughts on the sailing experience one the forward cockpit on an Atlantic cat vs this latest one, and some of the enclosed ones? So many trade-off's and there's nothing like learning from real-world experience.

[@alansmith2203]

O'Kelly's, loved the film on Zero. Isn't it funny how almost always we see these super expensive boats in the hands of old guys? There is a reason for that. I like your take on that. Maybe you could afford the longeron and ???. Because of your channel you get lots of invites on these boats. But to afford one of these boats takes some serious cash flow. I loved the story of why the boat was named Zero...."it is what i had left in my bank account after buying it." That is some seriously funny rhetoric. Had me chuckling for half a minute. I don't remember if you saw the For Sale listing of the Trimaran Avalanche a year or so ago? I have lusted after a Chris White design for years. I own a 30 foot Condor Trimaran which is trailerable. I had 3-4 long conversations with the Skipper about the boat. Watched all of his videos on KZbin about his travels on the boat. A seriously fast trimaran with huge off shore capabilities. He was selling it for bargain basement prices...unheard of prices for a 50+ footer in good shape. He is a rather rich man moving on to a HH full on racer/cruiser. He could afford the losses. It was being sold for around 250K. I could barely afford it if my wife divorced me...snicker. During one of our conversations we got around to what condition were the sails in? He talked about why he chose North sales. Talked for 15 minutes or so about offshore and ocean crossings what is required in powerful boats and sail design. So, I asked him how much his mainsail cost. Well, about 2-3 years earlier it had cost him over 80K to replace his old one. Holly Shizzle Batman!! I don't know...but somehow it was like someone snapped their fingers and brought me out of trance. Back into the real world of seriously expensive boats and what they cost not only to purchase...but even more important is what they cost to keep going. Remember the part where the North Sail guy...or a racing dude told the skipper he should have a carbon fiber rig? Everyone wants one...but few can afford that kind of bang for the buck. Love your search...I thought for sure you were going to buy the Chris White cat.....thanks for leaving for it to me to drool over.

[@TheOKellys]

Yes, the high end of this "sport" get's ludicrous. But....I'd like to think that if we had that kind of cash, we'd have a boat like that. The deals do come up every now and again, but it is a Who You Know sort of thing. By the time a boat makes it to the classified ads, a lot of friends and friends of friends have passed.

[@donmcneal233]

You guys are great as always & smartly venturing, highlighting this new marine focused paradigm. You're doing good though by not pressing for a cat.

[@steveturansky9031]

I'm 6'3" with a bad back so I can't get a boat where I have to hunch over. Low headroom boats are a big issue for us taller folks and it just becomes a bigger issue as we age and wear out. I'm certainly not a helm position guru - I wish I had much more experience. But I think it comes down to how you plan to use the boat. For short-handed cruising, I think a semi-raised, enclosable bulkhead mounted helm (like the Leopard 46) would be great. It'll keep you warmer and dryer (or out of the sun), for those long watches. If you are racing with plenty of crew, those dual aft mounted helms would give you best sail vision (Catana style). For chartering where you never have an overnight passage and do alot of motoring and anchoring, the 2nd story fully raise flybridge is probably the optimum (Lagoon 450 style). I'm intrigued by the Seawind style dual bulkhead mount unraised helms. Decent sail vision. Not too high for pitching seas. Not too exposed for wet or excessive sun. It seems none of them are perfect for all conditions/situations - It's all a compromise. I seriously need to spend alot more time on each type to decide.

[@TheOKellys]

Really no substitute for experience on these boats. More miles = better decision making

[@Four_Words_And_Much_More]

Wow. Way cool. I lead the change at Boeing where we used similar technology to make the aluminum hulls (fuselages) easier to assemble and less weight. The drop in labor costs were huge. Then Boeing used the same basic technology to do it in carbon prepreg material. Prepreg is lighter than the infusion manufacturing technology, but it takes huge ovens to cure these monsters. Then, because sometimes things don't go well, you have it ultrasonically inspect every inch of every piece. This adds a lot of cost because you end up throwing some of them away. That would up the cost of the boats about 2X. but you get a lighter and stronger boat. I think we may be talking about America's Cup Racing there. I love seeing the smooth surfaces created by a printed/machined/polished surface. I can do the same exact thing using a mill to smooth the inside of a more traditional wooden mold. It is all about understanding the technology of forms. Boeing did a lot of work on that while I was there. So I get a lot of the problems and solutions. They called it tooling. As an example: When I started the "tooling design group was about 3000 engineers." When I left, there were zero. Not one. The entire process of tooling had shifted into the CAD system and ever increasing computer aided design automation. All the automation was at different parts of the design-build process. Fascinating to see and be a part of the huge changes. So it was not only at the manufacturing floor. Great video. Great story. I love the progress I am seeing.
