Hi there, it is so nice see you guys floating around Holland my birth country, I was born in Amsterdam in 1942 and we moved to South Africa in 1956, so I was 13 when we left. We visited Holland once in 1975 and traveled around the country for 5 weeks with our only daughter when she was 7 years old. Nice memories, have a great visit in Holland and I will be following you wherever you go!

Sending electricity through ball bearings is a particularly bad idea - the electrical arcing can erode the hardened ball bearings and their races, which promotes the rapid wearing of the bearing surfaces. This may be the cause of the awful crunchy noise in the sail drive.

I wanted to give a shout-out regarding the great video and video editing in this step. Especially enjoyed how you incorporated the drone footage into the sea trial footage, how you filmed/edited putting the boat back in the water and the before/after, back/forth sound experienced comparison between the diesel and electric drive on the two different boats. All of this took a lot of effort in the editing room, was noticed, & was very appreciated.

I have watched Sailing Uma episodes from the beginning, and now, seeing this "sister ship," it really was like a walk back in time, particularly inside the cabin. What a sweet and satisfying reminder of all the work you've done it must be for you, especially on Uma's interior. She is really so well redesigned and updated now that she is actually like a brand new sailboat. You've done such great work in the redesign, and the workmanship in doing what you've done has been so craftsman-like. No, your workmanship has been nothing less than masterful. Huge kudos to you both. And now, the super quiet and efficient Ocean Volt motor that blended with the new sail drive is all but indicative of what you two have become together, a perfectly blended "power couple." What a team. Love you guys.

So nice to see a mechanic using proper tools and doing a professional job. One thing you may want to keep in mind is that the closer each of the three propellers are to the exact same weight of each other, the less wobble or vibration, and the less wear on the bearings of the sail drive also. It may not seem like a big deal but it can really make all the difference in the long run.

Their interior layout not only is done 50 years later then the original one, so using 50 more years of knowledge compared to the original designer, but mainly is a layout specific for the use they do of the boat, live aboard in only 2 people. The original design had a table on which more then 2 people can eat, had more berths, was a better design for short time cruising with more crew. They did a fantastic work on Uma's interior design, but it is not fair to compare it to the original one and if it is prefect for them would not be a great design for a production boat, as it is optimized to live aboard in 2 people, and it is not how the 99% of the boats are used for.

Of course if a company decides its worth while to get involved with a youtube channel and partner up as some form of advertising than they can, but it shouldn't be expected as a given which you seem to be implying (sorry If I'm reading this wrongly), Ocean Volt are already known as THE electric propulsion company for boats in the industry without needing extra advertisement and I say that as a long term Uma watcher. That said its nice that they decided to help out on this occasion, especially from the sound of it the fault wasn't down to a manufacturing defect.

given that they've only had their gear installed for a month or so and didn't buy it from the company, I doubt the company even knew they existed except for one of their Dutch tech reps who happened to follow their channel. And then invited them into his employer's wharf to check out their problems (the wharf they hauled out is the Dutch representative for Oceanvolt). I'd call that a pretty quick response.

You got a new sail drive with warranty and it is longer, which gives it better bite in the water and eliminates cavitation noise against the hull. That electric drive will likely produce more regeneration power due to the lower drag on the drivetrain. Well, all that worked out to your advantage! It was wonderful to see a sister ship to see the differences not only of the motoring configuration, but also the batteries, electrical, cabinetry, standing rigging, deck hardware, and the roominess. I’m sure you are quite pleased with your boat and of your accomplishments. Bravo Zulu!

A lot of love there ❤ and you are full of fun but I know this is hard work I've done similar things in my day I just sold my 1978 VW WESTFALIA CAMPER that I spent over two yrs restoring. I did put two solar panels the thin flexible ones that produced 48 volts and I used the Victron charge controller i believe it was the the same one you showed on one of your videos. I was only using it to maintain the 3 batteries on board. I only went on one trip with it with my Navy shipmate and went from Florida to Seattle. Were both in our 60s and driving a VW without power steering for me was tuff because I have all worn out parts in my body. So keep doing what your doing while you're young.

And these are the energy consumption with original prop: -1kn 100W -2kn 320W -3kn 700-800W -4kn 1kW+ -Full speed, 5,2kn, 3,3kW. These include the main contactor about 20W. This is actually very interesting and also gives overall idea of the energy needed for moving the boat even with sails! It has been very light winds so far so I haven't been able to test it in heavy winds or the ability to regen.

Been binge watching for a couple of weeks and finally got caught up. That was a shock in a way because I miss being able to just sit down and play another Uma episode whenever I want (often!). But it looks like I caught up just about the time you finished the rebuild. So now it really is Sailing Uma, instead of Rebuilding and Sailing Uma. You know you guys could easily consult on interior design and perhaps even write a book or do a series of videos (for patrons?) on the process of coming up with design strategies that increase liveability on boats. Also since you are on the cutting edge of electric propulsion, consulting and a book could easily be in the future if you so wish, especially now that you mostlly are done with projects and just need to do maintenance. When you talk, people who have any interest in electric propulsion listen!

The more I watch your channel the more i'm convinced that electric will be the way to go for my next boat, i've never run a diesel or outboard on a boat for more than 1 hour per day, but I have sailed on and off my mooring because I couldn't be bothered to start the motor.

Not sure if you motor 3 hours, how many time it take to recharge using solar (assuming no wind for regen because you want to motor) in order to get another 3 hour run. Let's say you can motor a day on two ?
@timhardman4764
@timhardman4764 4 жыл бұрын
I agree with Romain - Uma has an awesome setup but saying "electric 3hrs/day for unlimited days @5knots" is a misrepresentation that could be accepted as fact by those who don't understand recharge rates and all the variables related to it. I don't remember the size of their battery bank and the size of their solar array but they did mention the recharge rate from the prop at certain hull speeds. I think under ideal conditions (full sun and decent sailing speed for prop regen) theoretically, they can come close to fully recharging their batteries in a 24 hour cycle but how many 24 hour cycles out at sea are under these particular ideal conditions? Much fewer than 50%. Here is my very rough calculation showing how I arrived at my estimate. Assumptions: 1. 3 hrs at 5 knots drains battery bank. 2. Battery Bank is 12 Battle Born 100 amp 12 volt batteries = 14,400 watts. 3. 1,000 watts of solar array 5 hrs/day at 1,000 watts + 4 hrs/day at 500 watts + 3 hrs/day at 250 watts = 7,750 watts. Sail drive regen. average 24 hrs at 300 watts/hr = 7,200 watts. Actual watts produced from solar and regen (7,500 + 7,200 = 14,700) x .85 efficiency = 12,500. This very optimistic number 12,500 gets you charged up to 85% of the 14,400 watt battery capacity assuming you used 0 watts of your battery bank for running all systems, electronics, cooking, water heating, refrigeration, laptops etc... In REAL sailing conditions, if you used the motor for 3 hrs depleting the battery, you might generate enough power in the next 24 hours to get the battery bank half full again for 1 hour of motoring plus other electrical demands and that number is probably closer to the maximum "unlimited" days of propulsion for 1 hour, if lucky. Draining ones battery bank frequently will significantly reduce the performance and life of the battery bank even with Lithium chemistry. The Uma crew are real sailors and only use mechanical propulsion for short periods of time so this setup the way they use it does provide them with "unlimited" mechanical propulsion. To get them unlimited 3 hrs/day propulsion they would need to tow a barge behind Uma loaded with Lithium batteries covered by a roof of solar panels.

You don't always have to go 5kts though. Slowing to 4kts might let you go for 6 or 8 hours a day, and at 3kts, you would be able to motor a lot longer than that. You plan your trip for the available energy, and when you get there, you can anchor and recharge for free.

@MrGunboat78 Yes, that is the "best" setup for now for both safety and meeting a schedule. Depending on "fuel" from the sun for solar, wind for a top side wind generator and thus bottom side prop regenerator while sailing (due to wind) are fickle. One must overcompensate for these undependable power sources by carrying extra weight in provisions, batteries, water, medical equipment, etc... OR like you, a dependable diesel GenSet with enough fuel to complete your mission under the worse conditions in the time you have allotted. The Uma crew is young, in good health with no deadlines and a well provisioned boat. They figured out what works for them and I love that they are helping to push forward, by example this technology. It is important however not to oversell or over represent the current practical application of this technology. I don't believe they are doing this but others may be misinterpreting their capabilities and setting an unrealistic expectation for those in the planning stages of having an all electric boat.

@@brianorca No doubt brianocra a sailor can make this system work for them with good weather predictions of fuel replenishment in the form of sun and wind. Weather prediction is so much better now than it was 10 years ago but it still has a long way to go. If you have some flexibility regarding passage durations and you bring extra provisions "just in case" and you have an adventurer's attitude that deals well with uncertainty....you are golden. The Uma setup would work fine for me.

Really interesting, I liked being able to see the difference, I really love your boat by the way, all the refits are amazing compared to what it was on his, I did like his vinyl matting on his, how's it compare to your repaint texture on the deck? The other thing I think is important, he may have more range with the diesel, but you are OFF-GRID, so you NEVER have to refuel or do as much maintenance, saving tons of money.

I am wondering if you intend to convert to lithium - carbon batteries from lead - acid to complement your electric engine and drive system, adding new (if necessary), highly efficient solar panels which recently have become available? The "Sailing Brick House" channel has Rebecca's excellent exposition on implementing such a conversion. So to does the "Ran" channel (he seems masterfully handy at doing this conversion). The reasons to do so seem overwhelmingly compelling in numerous regards now that the technology appears non-susceptible to fire (a lithium - ion battery problem now surpassed by lithium - carbon technological advsncements, less heavy by half, less room consuming, etc. advantages. I am super enamored of your electric motor and was keenly interested by your having had it for 6 years - has it ever given you folks any trouble particularly from lightning. If you've had that experience? Denver, Colorado

You yelled the whole way and it was the new norm. so LOVED this episode - SO jelous of that new sail drive- good job.
