Technical Boat Tour: Voyage 590 Hybrid-Electric Catamaran | Step 378 

Dan did a great job explaining a complex bunch of systems. Kika gave a great topside tour. That catamaran is truly amazing.

Hey guys, YOU CAN'T BUY ONE OF THOSE!!! [it has a COUCH!] lol. Great episode, as usual, really enjoyed seeing you sail a Cat. Greetings from sunny Perth, West Australia. It was only 44°C here today, so probably nearly as hot as where you guys are. Cheers, Frank.

My big take-away from this video is that I can find interest in other boats; however, I'm most interested in YOUR boat, Uma! Safe travels ❤

Everybody needs 7 fridges and 2 icemakers! Maybe 3. And more stainless steel/chrome. Nothing gets you in tune with nature faster than hard edges.

I guess that’s why they call those “condomaran”. Glad to know that you are missing Uma and will return to her as I can’t wait to see what you will make of her.

Thank you so much for explaining the electrical side of sailing and informing its limitations regarding running in-house systems sides by side. Looking forward seeing UMA coming back to life

I'm glad to see you guys enjoying yourselves on water again. Please, please keep us in the loop with whatever you decide to do with Uma or a possible Uma II

Nothing like being with friends … all the best in boat work 🇨🇦 ❤

You guys are legends, the best of us. Like lighthouses to keep us off the rocks. Lol no presure

Outstanding boat tour and explanation. Glad the future does not include a Cat as UMA II. Great video and detail shots, but not enough of Mia; it was like she was a fifth wheel.😉😎👍🏽

Great to see and read about the electric and hybrid systems. Although i’ll never buy such a floating house (catamaran), but that’s another story😊

Really liked the more tech spec side of the video...never thought the 24/7 powerconsumption of the boat is so unbeliveable high, but when considering the 6/7 fridges, Icemakers etc. it all makes sense :D

Enough traipsing around in tropical waters enjoying leisure time and get back to Uma and make some vids so we can share in the refit, lol!

Glad that you will be back to UMA soon!

glad to hear that they had a good time and I hope they have plenty of ideas for Uma's upgrades

Now I am super curious how the systems on Uma are going to be set up!

Very interesting to have the tour of how it works and what it feels like, in advance of Gone with the Wynns taking delivery of their HH44 very soon. However, I'm with you - Uma is the way to go, and I only hope you can progress the MOUNTAIN of work needed without too much pain. What the luxury of a big Catamaran does is take away the real challenge of sailing.

‘’To get Uma float again” can’t wait 👍

Thank you so much for taking us along to live vicariously on your adventures.

How the other half live. Now back to the real world and the refit of Uma.

Me half asleep opened this video and got confused by the catamaran. I then remembered where you were and what you were doing.

Sounds like you really liked that floating house. Remember the don't buy a couch thing applies to floating couches too 😅

I am so happy to see you guys sailing again. Seeing the two living on land is OK, but it doesn't seem natural to me. When you two are on an ocean or sea both of you look as if there are no problems in the world, just peace, comfort and happiness. What do you mean you gotta get Uma to float again? She was floating the last time I saw her. It wasn't feasible to live on her but she was still floating. Also I must compliment Kika on the long, beeautiful, wind blown mess you call hair it is simply gorgeous. Never cut again, please. Dan, you lucky bugger keep that woman away from hair salons where they offer hair cuts.

On "Home Again" now for 2 weeks and enjoying every minute !!!

I can’t Waite till you all are sailing back on UMA an showing us all the beautiful places you travel to. I’ve been watching you two back in the beginning. I miss the sailing!

Nice to see you and Bo and Brandy are friends. Love both of your channels.

If you have lot of money and someone to take care of this boat its nice to have it. But i have never met someone living aboard on such a luxury boat. Always have a meeting! I was sure that at the end of the story you would go back to uma!!!

Thanks for the tour! You guys did seem to have fun throughout it all.

wonderful experience and show of the catamaran! Thank you!😍🙌

Hey Dan and kika. Happy to know that you were in Gorda Sound. Been watching your videos since 2017. Please stop by the Bitter End Quarter Deck on your Next trip in the BVI.. lots of love Kemron❤

Great episode! I love the big cats! Cheers !

It would be interesting if you guys could swing a trip on the Zen 50 with the Wingsail when it comes out. It may be the first renewables only vessel with a fairly decent turn of speed. The Wingsail is supposed to be not only more efficient than a conventional sail, but to be progamamble so that any idiot without sailing experience can sail it. In spite of my apparently being super qualified to test it, in that case, I think I will leave it to others! If it works, it will be great to get rid of the smell of diesel. The Wingsail also overcomes most of the problem about shading the solar, too.

Thanks for the tour of the boat. You two are living a good life. God Bless

Got excited hoping it was a tour of new stuff on Uma. You two are amazing, how far you've taken that little sailboat.

Best crew ever.

It was really nice to see you two back in the Caribbean. I had the impression that especially Kika shines a little brighter there.🌞 However, I'm really looking forward to some heavy DIY boat work, which is what brought me to the channel some years ago.

Just found your channel last week. I love it. Thanks for bringing us along. Safe sailing.⛵️

You did well to film that and hold your line. Right on the precipice! Great work you got My sub! Your challenge now is to top that one. 😊

Great technical review. Well explained why it makes sense to have generators for this purpose but seems to me a short reach to add more battery capacity, more solar and in other settings regen in order to completelt eliminate the fuel tanks and generators! Hopeful, but appreciate your experienced insights!

love these guys, excited to see what uma becomes😊

Thank you guys, strangely, I have enjoyed your luxury holiday almost as much as you! Your film making skills I think.

Enjoy the ride!

Starts out good and gets better at the 14 minute mark.

What an amazing boat!

Behind the control panels, there are a bunch of components made by Phoenix Contact, a company I am proud to work for!

Lovely boat! Maybe Uma wants a bow thruster.

22:46 - Speaking of hot showers, how's the pressure? I was recently on a chartered Bali cat and the (telescopic) faucet was decent but it definitely cannot be used as a shower! I tried to get some hot water out of it for a few seconds and the crew panicked because it drained the battery, so only cold short faucet water supply for the rest of the trip. A pull-out faucet DOES NOT make a shower!

Great info. On catamaran.👍🏼

The overarching principles of hybrid propulsion: 1. Power Source: Batteries. Enough battery storage to achieve relatively modest (5 kts), short-term (< 1 hr) movement by means of batteries alone. For hybrid cars, this would allow them to conduct the majority of their commutes via battery power alone. For hybrids sailboats, this would allow them to safely drop sails outside a harbor and use electric propulsion to motor both to a dock or slip, as well as back out into a channel or seaway before raising sails again. 2. Power Source: Diesel Fuel. Enough diesel fuel storage to achieve relatively strong (10 kts), long-term (>10 hr) movement by means of diesel alone. For hybrid cars, this would allow them to travel at least 500 miles between cities without refueling. For hybrid sailboats, this would allow them to motor several days out of doldrums back into wind-driven areas while topping off their electromotive battery propulsion. 3. Power Source: Solar Panels. Enough of a third source of energy (solar panels) to accomplish two things: - Beginning with a system that's totally dead, provide enough solar energy in one hour of average daylight to charge an engine starting battery enough to start a diesel engine. - At anchor, provide enough energy during any average 24-hour period to power normal systems on the boat for 36 hours, not including A/C. The 50% overkill will cover your panels' reduction in production over time. 4. The ability to use any system, directly, to propel the boat, even if the other systems are completely on the fritz. For hybrid vehicles, this means using diesel in town and electric on the highway, but each within their respective limits. For hybrid boats, this means using either system to drive the propeller, either individually or both. It also means getting at least 2 knots out of direct sunlight, alone.

Great job on the tour guys! Having a boat like that in a charter fleet makes a lot of sense for what it provides to the customer. If anything goes wrong you can't handle, you just pick up the phone and call the base and help is on the way. As a long distance world cruising boat I'd have some second thoughts. There is just way too much technology on that boat. I think you would need to have a minimum of two techies on board just to have a reasonable comfort level and I'm a technologist. I like the idea of a monohull with some tech but also a good manual reversion capability. Look forward to Uma's reconstruction videos.

I think, for me it would be hard to get back to your little boat, I know, it's different if it were my little boat, Lol! I can see you finishing your boat and selling it and getting a Catamaran, because they have so much to offer. Not a big fan of flying bridges though, nor a charter boat layout.

Kika's going to be spoiled after this. Dan's going to have to figure out how to put multiple full bathrooms on Uma. Perhaps a fact-finding visit with the folks who built the TARDIS would be in order.

With the short runs these boats are actually doing in the BVIs then the sail is pretty much there for decoration and, I suppose, a bit of fun. Probably better to use something like the Greenline 45 Fly, which you can buy in a hybrid configuration and has bigger solar panels without shading as there are no sails.You would likely be running the diesel less often than in this supposed sail configuration, but I suppose for what is really a holiday boat real world usage is not the main consideration.

The boat is ok , your tech explanation was good, the tour was enjoyable, the best part was the ladies, in particular MIA, of which we did not see much of, and personally can’t get enough of !!!!!

Truly awesome cat episodes. Gone with the Wynns just took delivery of a hybrid catamaran. Totally different concept. Get some ideas. Can't wait to see the new Uma!

Pretty creative hack using the MPPT’s as 48V-24v DC-DC converter, but from what I’ve read, it’s not a great idea, as if there is ever a fault, it is designed to short circuit the PV side which is not a big issue when it’s just solar panels, but when you have a 144 V 44kW battery up stream that your short circuiting… eek, at a minimum you would fry the MPPT, at worst…. Well… 🤯

With your new experiences on Cats now, maybe get a hold of the Wynn's(Gone with the Wynns Channel), they are about to get theirs for sea trials of a new HH-44 hybrid drive????

It’s the Chevy Volt of boats. I had a Volt and loved it but went full battery electric a few years ago. The complexity of the Volt worried me as it aged so I sold it after four years. I would have the same fear with a boat like this one. The complexity is well beyond the average owner to troubleshoot so when something breaks it’s going to be very expensive.

it looks like you guys had an awesome vacation! (despite that your whole life looks like a vacation :D )

I guess Uma's a thing of the past. Enjoyed the simpler adventure days.

‼️‼️you don't need AC in the Caribbean in the winter! Lawd🎉 That boat takes all of the simplicity and minamilisticy out of maintenance and pure sailing. 🤪 It won't last 2 seasons in the Caribbean with out serious maintenance 😂😂😂😂😂😂

I love all the technology and have many of my own alternative systems I've installed in my home but in this case I would stick to the dual diesels, there's just too many things that could go wrong that you would need a specially trained person to troubleshoot in most cases

Im building an electric drive trawler that will be hybrid. The advantage is range. No range anxiety. Plus, I can have ac when I sleep. And a small fridge.

I can see pouring $$$ into all the massive electronics and complexity. Roller furler is just the start of things.

What happens when you have a lightning strike??? What happens when salt water and/or salt air impacts the battery system??? What happens when you can’t control the boat without the electrical system. What heck is the cost of an electrical system for Uma??? ENJOY. Love your channel!!!❤❤❤

I have 2 battery banks on mine. We have a switch to either run 1 or 2 or both.

Beautiful looking boat! What do they have in place in the battery compartment for fire detection and suppression?

Good times🎉 many many systems on this cat, miles of wire, but I like it 🎉

Amazing cat. Wow

AND, what happens when there is a very intense moisture problem bc you are on the ocean. Have more fun. ENJOY. Love your channel!!!❤❤❤

I can’t see why one would opt for this hybrid setup as opposed to just having two diesel engines to power the boat . As you pointed out having a generator running when you’re at anchor is unpleasant for those on board and annoying for your neighbours. I get the point that solar panels can get shaded by the rig but with a bit of ingenuity and more panels I’m sure this can be avoided. There is always wind and water generating power available to keep the seven (!) fridges going and obviously if the boat has ICE power then batteries will charge when motoring.

Not found of the boat but love the hair!

Ok guys I wouldn’t be mad at you if you was to buy a cat. I honestly could see the comfort in it and like you mentioned the open is Awesome. . Great video guys and cheers 🥂🥂🍻🍻

Dan : " Really easy to source and figure out if there is an issue " LOL - sure it is , every joe at some remote atol will be able to repair that himself no problem . In reality a simple standard instrument suit with say a bad wind transducer , chafed wire or intermittent termination can be days to sort out . Immagine when that stuff is 15 years old . I cite the fact the furler stoped working - now what ? That could be really bad in a passage . Better have deep pockets to keep it all running and not stray far from a decent repair shop .

Well this has been interesting, but frankly I miss Sailing on Uma. Can we expect to see some video's of this trip on Beau and Brandy Sailing ?

When are you taking the defender to Electric Classic Cars in Wsles UK to be converted? They have kitsets that will make that thing a thousand times more reliable, faster and all round better.

Time to get back to work on Uma? Will it ever sail again?

15:09 that's where you put the Jedi's and Wookies.

Boat designed for charter, entertaining, short tris, redundancy, all the conveniences. Massive.

You seem to feel like the one time I upgraded to first class on an airline flight.

Gotta question if i bought a sailboat a small one and i want to live in it full-time but the sailboat has nothing completelly gutted no electronics nothing but a floating sailboat i just want to live on it docked or just on anchor somewhere but it does have a running motor and the mast is down ,should i try this or no

Great video as usual! If you were looking to outfit a cat to be as full electric as possible. Is there a system you would recommend?

I like solar and wind generation, but I truly believe the future is hybrid, we can combine all 3 systems, eventually the Generator will be needed, specially on long passes.

Nice

Great video, it’s good to experience some luxury from time to time. I watch carefully each of your episodes. In one of previous you said, you were going to visit Haiti. I wonder if you manage to get there, and what situation is there now? Will you tell wide audience something about it?

Like all electric boats, you never want emergency power for emergency situations because it's just not there. For charter short hops between anchorages, it seems to work OK. For a high-windage boat like a cat or tri, I would not do this.

WOW!! Beautiful, however I like UMA better!

I think Uma 2 is coming

Lekker man lekker 🇿🇦

Great show enjoyed the content one question , that boat is set up for 14 people . UMA is set up for 2 people . How does its power consumption stack up to 7 UMA's ? Taking into account the larger boat would be set up much different if you owned it . On regen and amount batteries would drain before Gens kicked in . Since it is set up as a comfort power hog right now

It looks that might almost press button in sailing seeing that most electrical are set automatically or press buttons very unique

Dehumidifiers are cheaper to buy and massively cheaper to run. They keep you cool in the summer and stop you getting cold in the winter. Moisture is the main constituent in transmission of heat energy through convection. Remove the moisture and you get dry heat rather than swampy muggy air. Remove the moisture and the damp air that chills you to the bone has gone. It also stops mould and mildew. And it dries your clothes cheaper and better than a tumble drier, you just hang your wrung out clothes on coat hangers on a rail. Your wet weather gear dries to. And you can use the grey water from the dehumidifier to wash your salty clothes with. Unless it is a specialist drinking water dehumidifier DO NOT DRINK the fresh water from it as it will contain lead and other heavy metals from the heat pump cooling mechanism as well as being standing water exposed to constant airflow so it is probably full of bacteria.

Looks to me that the cat platform easily beats beats the mono as a home to live in, and they seem to sail faster in many conditions. This from a land-lubber.

Wow, the logic infused to say your diesel cat is green.

If a mono hull boat is like a horse and carriage then a catamaran is like a modern car. If you can eliminate sails and rely on solar power with a generator for a last resort it is like a private jet.The last one won't happen in my time but it will happen.

Hope Uma gets 12/24V house batteries with seperate feed from solar panels for resiliency.

Just wondering why they are still running dc motors. Kind of reminds me of some of the old car conversions.

A great boat for it's purpose.... to act as a small cruise ship. I guess the label Hybrid-Electric is the new catchy title for things but I would call it a diesel with an electric transmission, in the same way some cats use hydraulic transmissions. While it is true it can be run on the batteries for a short time, I would argue that the batteries are protected from over charging in this manner rather than being made to motor electric only. Electric transmission is still a great choice if the prop is designed to use the electric motor's strengths but I don't see that. Running the house bank from the motor bank makes the house bank smaller as well as redundant and runs the gensets less often. The comments about outdoor space and other amenities, need to tempered with apples to apples comparisons. That is this boat should be compared to a similar priced mono-hull.... which would be much longer and have a hull that is quite wide too (as most newer mono-hulls are). such a mono-hull would likely still have a lot of outside areas and dual drives too. I can understand comparing this with what one already has though, I would do the same thing.

UMA!, UMA!. 👏👏 💪❤🍷

Hey guys ✌️⛵⚓⛵✌️✌️✌️✌️
