Dan and Kika are architects and contractors. Few boat owners have their education and, or, skills. My guess is that if one paid to refit a boat the way they've done, the cost would be more than $100,000.

@@gustavocabrall What's the alternative to this "technology"? Diesel engines? They're at least equally expensive and they definitely break all the time (oil leaks, broken impellers, fuel contamination...). Especially in a boat environment they are far from being more reliable than an electric engine. Take a brushless DC electric engine like the ones from Torqueedo (Torqueedo Pod engines or Torqueedo Cruise outboard engines) that don't even need active cooling, because the actual drive unit is submerged under water anyways: they are literally maintenance-free. And what you pay for the batteries you don't pay for fuel. Last but not least, redundancy via multiple separate battery/charging circuits is very easy to implement with electric systems. The boats that are closest to being maintenance-free are actually those that 100% electric: solar boats. They have almost no moving parts and an unlimited supply of free energy, with no wear&tear on things like sails and rigging. While this might seem like an unrealistic concept, a few companies are already doing it (Silent Yachts Austria, Soel Yachts, Azura Marine / Aquanima .... and many more).

Seeing how you meticulously sand and prepare surfaces for fiberglassing and painting. All the testing that you do on your new equipment. These are the things that up front add extra time but in the end save big headaches! This is the first time I have seen something not go exactly as planned during one of your tests and it really does make the preparation worth it, even if it's only 1 in a 100 tests that doesn't go perfect.

Akfu 84 I brought this point back in their install video, may not make much diff while cruising but when docking or very slow speed that extra distance from prop to rudder will be significant in control response lag time. I was giggling seeing their first attempt to dock.. I'm sure that now they are aware of the diff, they will practice maneuvering at slow speed. Not sure programming will compensate for that but using more initial power to initiate slow speed turns will likely be the only way to mitigate the lag... not sure why the motor drive was installed so far from the rudder...

Hi, thank you for this video, I learn a lot from watching. Seriously, You two are making history, from the cutting edge. I know that you are way ahead of me from all of your first hand experience, but there are some comments that are not consistent with what you're saying, so I would like to expand a little on what I'm seeing. Please forget for a moment that the propeller pushes the boat forward and pulls it backward through the water. If you think of the propeller as a paddle wheel (mounted like a propeller at a right angle to centerline of boat) it's easier to visualize the way that it takes water from one side of the boat and delivers it to the other side. The sideways flow is the water passing under and around the prop, not the prop shoving water through the gap between the prop and the hull. With the prop mounted closer to the keel (farther forward), it has less leverage to turn the boat and is more inclined to simply pull the whole boat sideways. Your old right hand propeller, when in reverse, would take water from the port quarter and deliver it to the starboard side ("backs to port"). So if you're trying to make a tight right turn, if you spin the prop in reverse halfway through the turn, it will not only pull the stern to the left (helping the boat turn right), but it will slow the boat's speed through the water, further reducing the turn radius. With the new LH prop, I would expect her to turn left better than right. The other thing that makes a boat turn sharply is the way its propeller shoves water into the rudder. If the prop is moved forward, away from the rudder, it's going to have less ability to bounce water off the rudder, to help turn. What I said first applies to Forward as well as to reverse: in 'Forward', the RH prop was stealing water from the starboard quarter, and putting it on the left side of the stern. This means that when you are in Forward, it is actually trying to turn the boat left, not right. But even though it is working against making right turns, the boat will still turn right better. Because in Forward, you can goose the throttle for a moment, enough to shove some water into the rudder, but not enough to gain headway. But if you are turning left, and you need to turn sharper halfway through the turn, putting the boat into Reverse will only make the boat resist turning left. That's with the old RH prop, farther aft. The effect from the propeller taking water from one side, and putting it on the other side, is less noticeable once the boat is moving through the water. Going Forward, with the old RH prop mounted aft, you could Start a turn either direction, and if you weren't in a tight spot where you had to slow down halfway through the turn, yeah, the boat would turn sharper to the left, but moving through the water the rudder is going to overpower the paddle wheel effect. So, with a right hand prop, and less speed, the boat Will turn left better. In theory. I mean with little way on, and goosing the throttle just enough to move water from stbd to port aft, but not goosing it enough to gain forward way. To help counteract the way the RH prop would turn the boat left when in 'Forward', the old prop shaft was angled to starboard. This shaft would not have worked all that well with a LH prop. Forgive me for being so wordy about this, I'm just trying to be consistent. So, with Uma's propeller farther from the rudder, it has less leverage to spin the boat, and less effect when trying to bounce water off the rudder. Now there is More reason to benefit from a bow thruster, because the prop has less ability to manouver the boat. This has been a problem for a lot longer than there have been sail drives. Older full keel racing boats with tiny props in tiny apertures may be able to shove a little water into the rudder in forward to help turn, but in reverse they were useless. I am not going to talk about that because this is supposed to be about Uma. There have been Lots of production boats with the props forward like this. Like Cal 40's. Ericson 41. Lots. All I would like to say about reversing "difficult" boats is: Put it in reverse. Goose it, not enough to cavitate or make everybody in the marina stop and look, but don't be timid, either. First thing that's going to happen is the boat is going to turn sideways. Uma will turn less than a boat with the prop further back. Keep the power on, though, until you get past the sideways-ing and into where it you start moving backwards through the water. Once the boat is moving through the water Back Off on the throttle. The prop will stop turning the boat and the rudder will start Steering the boat. If the boat slows down too much to steer, goose it again, then back off and steer. It's OK to gather a little speed, but too much speed backing up could grab the tiller (wheel) out of your hands, so go easy. Point the rudder blade exactly where you want the boat to go. Stopping is no problem, just put it in 'Forward" and the boat will stop quickly. Which is the opposite of going forward and trying to stop by putting it in reverse. That doesn't work so well sometimes. So, from personal experience, and this is just my opinion not necessarily fact, but the noise is not the motor. When the tip clearance between a prop and a hull is less than 10% of the prop diameter (or so), the spinning prop blades will compress the water between the two every time the blade passes the hull. Not sure what the official name is for this but we just call it "prop pound". You will notice that if this is the case, there will be a vibration that you can Feel through your feet as well as the noise it makes. I suppose you could say it may have a destructive effect on the propulsion system, but it is not really the end of the world. It is what it is, I just do not believe the noise is from something else. Thank You

The propeller being further away from the rudder might be one factor that affects the maneuverability, just like several comments suggested. A much more important factor is that your old shaft drive had a right handed propeller, and the new folding prop is left-handed. So the propeller walk effect (asymmetric thrust) is to the opposite direction than what you are used to. When reversing a left-handed prop always moves the stern to starboard. This is what happened both times when docking port side to the pontoon. Whenever possible, you might want to choose to dock starboard side. It is much easier with a left-handed prop.

VERY nice work on the re-power and hull work! (10:25) When slipping lines at a dock, you often position crew off the boat and on the dock, tossing lines onto the boat as she's in motion, and then clumsily re-boarding over the lifelines - again whilst the boat is in motion. This creates opportunity for risk (such as allowing a line to fall into the water and possibly fouling in your prop, or Kika stumbling as she rushes aboard (and over the lifelines) onto a a vessel that is now making way. Try "two-parting" your lines from the boat, by leading docklines from the boat to the dock, under the cleat and back to the boat where it is made fast onto Uma's cleats rather than on the dock. In this manner, Kika can simply unfasten the onboard hitch, and withdraw the lines onto Uma whilst remaining ONBOARD and inboard the lifelines. When down to one line remaining, the final line may be used as a "spring" line to lift your stern away (turn the wheel towards the dock and come ahead onto the spring line). Just before you reverse, center your rudder, and instruct Kika to withdraw the final spring line (midships or forward), and withdraw the line onboard. Easy-peasy, professional and much safer. Your new sail drive has positioned the propeller much further away from your rudder than the previous shaft drive. This new posture is contributing to your close-quarters maneuvering difficulty. Prop "walk" (the horizontal vector forces resulting from the prop grabbing water from one side of Uma's centerline and tossing it out to the other) may work for you or against you. You've also changed the propeller dimensions and are probably suffering much larger prop-walk when the motor is engaged both ahead and astern. W ps: Tides do not "come in" (10:45). They rise or fall vertically ("Rising tides lift all boats"...). Horizontal movements of the waterways are "currents".

Hi Dan and Kika, when you come alongside the pontoon you could maybe lasso the end cleat on there and motor against it. That'll bring the boat alongside nice and easily. You can do it single handed, there's no longer any need to be close to the pontoon or step off the boat, and you can ease your mooring line to get the boat in the right position. Once you're there keep motoring against the mooring line as a spring until you get your bow and stern lines on and both springs.

Fantastic editing again. OK. We know we have to berth into the forces. But cutting to the chase, the pivot point and wind is more in your favour if you reverse in. You go in hanging off your prop like a wind vane. Then get a stern line on first and hang off that instead. If being blown off your (port or starboard finger) your first line may be better mid-ships followed by stern. My "Hanging-off" concept. In my head it's like a walking stick. Balance a walking stick on your finger. The crook will affect it's centre of gravity (just as wind/stream does Uma). Now control your balanced stick into a hole in the ceiling three steps in front of you (without touching the sides) Very fine control needed. OK bear with me now. Instead, suspend the walking stick's crook on a line that's leading from the hole. Pull in the line. Getting through the hole now just needs a little lateral adjustment on the bottom of the stick, to counter the wind/stream. And maybe a timely mid-ship line. On a wet Wednesday, in lively wind and in the middle of a mid-springs stream, go to a lonely bedraggled mooring buoy, wet from the chop. Approach and maintain a two meters off bows-to position. Balancing=harder. Then do the same in stern-to. Hanging=easier. Do both lots and lots. One of these is a single-handed mooring technique.... Buoy and marina..... AND offers a contingency get out of jail back out plan B of easily reverse ferry gliding back out of the fairway. Buy Duncan Wells' "stress free sailing", even I coughed up for it. It has oodles more pragmatic ways to just do things better and with less stress. You saw him at the boat show demonstrating his man overboarding thing. The walking stick is mine though.

Test the docking maneuvers in the open water. You can see how prop walk and prop wash behave with the new motor/prop out in the open before trying to dock. The same applies to mooring and anchoring. Try it in the open first. Same applies to anyone chartering an unfamiliar boat. Try the different moves in the open to see how the boat responds to docking/mooring/anchoring maneuvers before needing it for real.

I think you know this but some of the issues you are noticing are due to having gone from a fixed prop to a folder. That will make a big difference in handling and one thing you DO NOT want to do is fling the blades from forward to reverse under large loads- at least not too often. I think you can adjust pitch on the prop for forward and reverse independently and that might make your lives a bit easier as you ease into the new equipment. If you can do this going to finer pitch while in reverse will give you more "bite" and less P factor which is the primary component of "walking". I admire your skills guys, that installation couldn't have been done better and you take care of your lovely little yacht very very well. Calm seas and following winds to you!!

@@bobadam7021 You engage the prop in reverse, then go back to neutral. The force of the water on the prop keeps it open and spinning, thus regeneration occurs. It's a rather complicated system with many points of failure and since we rely on regen to power our electronics while we cross oceans, we opted to stay with our fixed 3 blade prop. It always worked and gave us enough power to keep the fridge on the whole way across the Atlantic! You should check out our channel, we have been cruising for 3 years with our electric motor.

The folding prop will make docking more difficult due to the "mechanical" lag needed to get the prop into proper position. OK, so help me if you can because I am a bit confused.... a folding prop is used to eliminate much of the prop drag while under sail. How can you use that to create re-gen electricity? Can you lock the prop in place so it can be spun by the water and in turn spin the motor? (by the way, nice "framing" of your subject in the video and good editing!)

@@Andrew-lk5ov IMHO: You have to electrically spin up the motor in forward "gear" to unfold the prop. Then the prop needs to spin a little slower than for driving at the current speed. So the surrounding water trys to spin the prop faster. The electric machine is counteracting this momentum while generating Electricity. Naturally you always need to unfold the propeller electrically to kick off the electric generation.

THere are (at least) two different types of folding props. One type uses centrifugal force of rotating to open up the prop. Works great forward but pretty bad reversing. A different type change the pitch of the blades but may or may not fold. A third type can both fold and change direction of rotation which is what I believe what Uma now has.

@@raho118 Sounds like a lot of potential failure points. This is why we chose to stay with our fixed prop when we switched to electric 5 years ago. Regen gave us plenty of power on our Atlantic crossing from the US to Europe. If we were coastal and not dependent on the prop for power, a feathering or folding prop would be something I would consider, but out in the ocean, I want as little complexity as possible.

When docking without a bow thruster and a single engine,I always tie the bow first. Then I have control of the stern with the rudder and the motor in forward. So on a port tie I would have the bow tied first with the line to the dock leading aft, then turn the rudder hard to starboard with the engine in forward and it should suck in, and you can re adjust the lines. Hopefully you are getting enough thrust against that rudder. That style works best with outboards but I was taught it on a boat with a skeg hung rudder.

If you can afford it, get a feathering prop.Much more responsive when reversing especially. (much faster breaking). Depending on how close your saildrive is to your rudder.Keep in mind.With less prop walk. Blasting forward stears the boat (water blasting against te rudder). Without changing rudder, reversing mostly slows the boat (pulling water it takes it from all around the prop, not nearly asdirectional of a flow). There is a video where a sales guy showing off a sirius DS 35 shows that, turning the boat on its keel either direction (Diesel saildrive). I've done the same thing with my dad's old boat many times (also a diesel sail drive). I haven't done any docking with a folding prop, but the boat next to the one I race on has one, and they don't like to reverse the engine until they have some ropes on the dock. I have undocked that boat (with help from crew and ropes) and it took quit some RPMs before you got any action going backwards.

Can you charge batterie when sailling even with a folding prop ?
@brewmagoo589
4 жыл бұрын
Yes, the Oceanvolt drive system can regenerate the battery with this prop. The folding prop is a Gori 3-Blade propeller whose blades can flip 180 degrees for forward and reverse, and have two operating modes, normal and overdrive with different effective pitch angles. Overdrive is the most efficient mode, meant for motor sailing and low RPM motoring. I believe to generate energy while sailing, they must briefly motor forward to deploy the blades, shift to neutral and engage the hydro generating mode. The computer controls the RPM to prevent the blades from folding (maintaining centrifugal force) and maximizes the power generated. They must be sailing above a minimum speed for the hydro generation to work (6 knots?)

prop wash on the rudder is key to slow speed manuevering. without prop wash you'll need some way on to get laminar flow over the rudder surface to make it respond. it helps to learn to use your lines to dock when you cant get the steering response from your motor. for instance, bow in mid-finger with a spring in hand, and pin it as soon as possible even if its not exactly where you want it. pull forward or to the stern on the spring as the conditions demand to pull your boat parallel to the finger. free your spring and motor forward into position to tie up. good luck :-)

I have to agree with others as far as the distance from the prop to the rudder. That is where your lag is now. It takes time for the prop moved water to hit your rudder during low speed maneuvers so you'll need more quick but higher rpm hits of the throttle along with rudder inputs to kick the boat one way or the other.

That’s not the lag we noticed, nor is it even a noticeable difference from before. What we experienced is a lag between the prop spinning in forward and then shifting to spin in reverse along with programmed in lag in the controller to protect the prop.

"Characterization" test needs to be done under load (i.e. in the water). You basically have a 3 phase AC motor driven by a DC variable frequency motor controller. There is some feed back mechanism that tell the controller that the rotor is in the proper location for the present phase to be turned off on the next phase to be turned on (not truly ON/OFF, that would be a stepper motor). If the rotor is not in the correct position (because of heavier than expected load) you are wasting power. Another way to think of it is a motor acceleration test with a load (Clearly no load out of the water.)

Just catching up by binge watching you adventures. I am most impressed by your boatwork abilities. However, I have seen Uma’s manoeuvering issues coming in this case. I strongly believe that the decisive factor is that your new propeller is now located more in front, closer to the keel and further away from the rudder than the old one. That means that it takes more time until you get sufficient current on your rudder when the prop starts rotating. (I was wondering when watching you installing the motor if it would not have been possible to move the saildrive a bit further back.) We have changed the (diesel) motor on our boat about 15 years ago, also to a saildrive. In our case, the new position of the prop was further back, closer to the rudder than before. The (positive) impact it had on the boat’s manoeuvrability was enormous.
