Again, credit to the editing here, from 5:00 to 6:50, getting that mounting plate out. Many would have just given us a speeded-up whizz, there it is, OUT. Instead, whacking here, whacking there, whacking from above and below, buzz-saw here there and all around, and it STILL hasn't moved, after a minute and a half of brief extracts. You trust us to keep on watching, not skip the video, and because it works, we stay with you. It's that sort of admission that keeps it real. I do get the feeling that if I could come and be an unskilled labourer/handyman for you for a week, this is honestly and exactly what it would be like. Thank you for sharing.

[@daves8407]

That split view for the motor bed glassing was so cool. Nice edit

[@stopthephilosophicalzombie9017]

That was top notch editing.

[@fireblade1986]

it's to humid. you can try to prelaminate a big sheet in between two plastic foils, creating a kind of prepreg. then just peel one side of and stick it on, then peel the other side and cover the outside with a foil ASAP. kind of hard with the overlap though. otherwise you need a tent and heater in there. humidity needs to be ~80% max and surface 1,5deg above dew point. greetings from an wind turbine rotorblade technician... it's winter break for us because of the weather ;)

[@fireblade1986]

ah sorry... cut the prepreg to your stripes with the foils on it.... Also try to use spatulas for laminating and or foam rollers... way less humid air gets into the resin this way

[@avidmisreader]

Yeah for heater idea isn’t there some sort of big already insulated conduit spiral that would be easy to adapt to the hull..

[@stopthephilosophicalzombie9017]

@@fireblade1986 What are "plastic foils"?

[@mikeisanisland]

Exactly. I've used a heat gun very carefully to preheat the hull and after laminating to help with curing to drive out the moisture

[@christianp1788]

I agree. The only times I've ever seen epoxy foam like that involved too much moisture. Options are probably or either wait for better weather or create your own conditions. If it were me I would tent the worked area and probably heat it too, depending on temps. Boat work being weather dependent sucks. I tried to go work on my engine today and I had to give up because the side decks were a solid sheet of ice.

[@MrAesthet]

I was very suprised about the dual motors on Laura Dekkers boat in your last video. Differential thrust and double the prop walk in a monohull - what a gamechanger in terms of maneuverability. This recipe + the benefit of double the regen = 🤯

[@samfromportadown]

I don't know if Oceanvolt props are available in both clockwise and counter clockwise versions, or if they all turn the same way. If it's the former, you could have the two props turning in opposite directions and there would be no prop walk issues.

[@MrAesthet]

@@samfromportadown Think they should be, as many cats use them in dual configs. With counter rotating props you have no propwalk when using both in the same direction, but you can also click one in forward and one in reverse and walk the boat sideways.

[@stopthephilosophicalzombie9017]

@@MrAesthet Wouldn't one forward and one in reverse create a torque on the hull like a bow thruster?

[@jabberwockytdi8901]

@@stopthephilosophicalzombie9017 That's not what was meant, comments are about having the 2 motors rotate in opposite directions with handed props to eliminate prop walk - side ways thrust from 1prop ( or 2 or more rotating the same way ) so called paddle wheel effect.

[@bernardgendron4310]

Never thought I would experience ASMR epoxy! Love what you do.

[@ArcticSeaCamel]

No wonder I caught you at the Oceanvolt booth… 😅 That is great setup! I’m gonna have something similar. Are you going to do any skeg or something at the front of the saildrives for protection? An yeah, my small experience says that your epoxy is too cold. When I’m doing stuff in cold, the epoxy goes in almost like a foam. But that’s just air getting inside the structure I believe. It will come out when you leave it settling - if there’s enough time. The type of roller also affect this. You seemed to have pretty long haired roller. Maybe more solid one would not put that much air in? And also there’s differences in epoxies and how they stand cold. The first one I tried didn’t cure fully at all…

[@jannepeltonen2036]

Had a similar thought about something for protection. Not protected by the keel anymore.

[@fluffywarhampster]

its funny that i started watching this channel back when you guys were rebuilding uma for the first time and now i am her watching you rebuild her again. how time flies

[@kendallartusi]

We are enjoying this project. However as you were removing the glass (smart move) you mentioned getting some acetone for cleanup. Yes that will work but generally for Epoxy resin we use denatured alcohol. We use acetone for polyester resin. I had the exact same issue with a glassing project on shaft logs (using epoxy). We ended up with some electric blankets preheating the hull itself before getting the epoxy to cure properly. We left the electric blankets on after we re-glassed the shaft logs for 24 hours.

[@Kariwable]

The filming is SOOO good- definitely the best of the sailing KZbin channels.

[@LabRatJason]

@29:48 - That has to be the coolest damn shot I've ever seen! You two are so clever! Uma is clearly in good hands!

[@PtangPtangBiscuitBarrelSmith]

Merry Christmas D&K Have a good one.

[@Paul-e1p8n]

2 props : more regen. Okay, but with 2 props more drag too, and more chances of stuff getting entangled in those saildrives because they are no longer (or at least less) protected by the keel. What about efficiency? Are 2 better than one? What about costs? (In case you don't get them for free..) Manoevrability increases: ofcourse, but is that such a big need on a 38ft with a short keel and rudder in skeg?

[@angela1984a]

My guess is that they primarily want the 2x regen. It's the by far best way to generate electricity when sailing. So they're probably ok with the negatives. Also guessing that they are getting a discount from Oceanvolt. If they instead had a catamaran or a trimaran, then they would consistently be able to hit a lot higher sailing speeds regardless of wind speed. Then two Oceanvolts wouldn't be necessary. See Sailing La Vagabonde (SLV) as an example. SLV 'only' has one Oceanvolt, but since they are often sailing between ~8-12 knots, they're pulling in lots of power regardless…

[@Edmund_Mallory_Hardgrove]

I just asked similar questions. Obviously, they'd have more power with two engines instead of just one, but since they'll have to run both motors when underpower, I don't see how this helps them. Unless there's some math showing that running both motors at a lower RPM will increase efficiency and range. I don't know. The other question I have is how much having those two sail drives in the flow lines of their small 36' Pearson will change the sailing dynamics and create drag. As far as price, this is something that a professional KZbinr could do to demonstrate what can be done. I think the starting price is around $12,500 for just one of those drives, so they'll have roughly $25k-$30k invested in that drive system. This would be tough for a mere mortal to do on a 1972 Pearson 36'. But then again, doing a refit like this is something that only a professional KZbinr could do for educational and informational purposes. It would make no financial sense for your average Joe to do any of this to a Pearson 36'.

[@itsverygreen532]

Exactly, there problem has always been getting enough energy to power one motor, having two motors will just make it worse. More drag even when feathered. In regen mode, if you imagine you lose 10 miles of distance covered in a day, you'll just los 20 miles with two props in regen.

[@antc5010]

Yes, I don't get the energy benefit. A yacht of set hull design and sail area produces X kinetic energy. This is finite, so by extension of their reasoning why not add 4 sail drives. Surely that's better?... well no! Everything is limited by X and hull friction plus mechanic inefficiencies to the drive (more friction) all take a toll. This is not a perpetual energy machine, so adding more sail drives instead of making the one drive more efficient leads to a downward spiral of efficiencies. If they choose to motor Uma on 1 sail drive in marinas, there is some positive saving. If more electrical energy is needed, I would look at increasing solar panels on the coach roof and deck to avoid windage and cut back demand with more efficient devices onboard.

[@mukkaar]

Yeah, but in sailboat of this size, solar just isn't reliable way to get electricity. You don't have space, and it's going to be blocked by weather or something else quite often. And if you want to be comfortable and save on running fuel costs, loosing bit of speed for more electricity is worth it.

[@jrstrande4890]

Calling it. The next refit will be 4 Oceanvolts! Thanks for the video.

[@brentengle7302]

Yeah, but didn't they get their first Oceanvolt from a guy who had a cat with four Oceanvolts and found he didn't need but two??? Lesson learned? maybe...

[@francesconicoletti2547]

Bow thrusters ??

[@SailingUma]

No need for a bow thruster if you have twin motors.

[@markisLem]

Maybe they could have left the original in and had three Oceanvolts.

[@IndustriousPursuits]

29:42 DAYAM! That's some creative filmmaking. My vote for best KZbin shot of the month.

[@peterlert3809]

Another great video--thanks! 1.) Having built a fiberglass/epoxy aircraft in a mountain cabin, I think you're right: it was just too cold. Finally finished at least the tail section by heating the basement to 70 degrees. Let's not talk about our electric bill for that month... 2.) You guys really might like to have a ratio pump (or even two--one for vinyl, one for epoxy). Not cheap (around $400 from West Marine or Aircraft Spruce), but for the amount of work you're doing, probably worth it as a time saver...and easy to sell when you're done.

[@SailingUma]

We thought about it. But we're not using very much epoxy on this build. As for the vinylester, it's super easy to mix without any kind of ration pump since it's just a 1-2% catalyst to resin ration. We just have a graduated catalyst bottle.

[@pwysor]

Spin Uma on a dime! I love a dual motor set up.

[@jfrazao]

I played extensively with this concept in RC boats, my two cents is that you want the the propeller aligned with movement of the boat and "center of mass" you need to apply the force vector on the center of mass, anything else either does cavitation or is going to sink your stern and boat will be unstable and jumping. See ziphius aquatic drone

[@jfrazao]

In sailboats I think center of mass is around where mast Mets keel

[@jfrazao]

I am also a sailor with my own boat, The angle that you decided is going to make the boat to rotate around that point making it hard for going against weather, front waves. That instability will also make it very anxious and nervous in respect to maintaining heading. This is my experience with ziphius water drone

[@jfrazao]

Very impressed and inspired with your courage and ideas, two contra-rotating propellers is definitely a plus.

[@jfrazao]

To be clear, Vertical aligment (tilt), must point to mast base, the yaw alignment should be parallel to keel so that you have a torque moment to help turn, like in powerboats and catamarans.

[@daleanderson7629]

@@jfrazao Does that apply on a low speed regen focus design? does the cost to performance under power and slight decrease in an already greatly improved docking maneuverability hurt more than the regen benefit. 6 degrees at high speed / power boat is potentially a bigger issue (I understand the angle could be quite a bit more relative to the center of mass / rotation). but at 6-7 knots is it as much of a factor. PS thanks I know understand what looked like excessive shaft down angle on some boats that's bugged me on some boats thanks to your explanation

A 6 inch wide by 6 ft long strip three layers thick 1708 due to the cold I believe it was like the high 40 degrees Fahrenheit when I did the layup. It just never cured and had the consistency of gooey Taffy. I had to rip it off and redo that section. I feel certain you guys got it figured out and took care of the problem.

Some try to avoid cutting new holes in the hull… This should give cleaner water flow over your rudder as well as the redundancy of a second motor. Y’all are fearless!

[@theyshouldhavenevergivenme5439]

It becomes nitpicking at this point. That boat was purchased for what, $5,000 (?) and it is at least 50 years old if I remember correctly. These supposed water flow and rudder tweaks become increasingly irrelevant at that age and at this point. The entire weight distribution has been altered as well. You are not going to be able to even measure 'increased' this or 'optimized' that with any kind of certainty beyond 'how it feels' compared' to before. The beast's performance becomes basically a matter of subjective interpretation and comparisons can only be made to the previous already heavily altered version of affairs of the vessel. They should rename it to 'Frankie' or SV Frankendaaaayum' ) ;;)

You guys rock! Thank you for providing such interesting and informative content.

[@richardwallinger1683]

JUST A THOUGHT .. the twin motor set up would benefit from some anti reef protection .. the keel protected the single motor set up .. Although the keel extends below the Ocean drive .

[@petec9686]

Glad I'm not the only one who thinks this is a dumb idea. Yes, 2 motors increase potential regen. They also increase drag and greatly increase the chance of fouling on whatever they come across. If increased regen is your goal, a larger prop would do the job IMO.

Hi to you both,I would think that with all the varied work that you have done to the boat that you never need to think that you are not good enough to complete what you want to achieve.A rotating propeller always creates more drag so surely you will be producing twice as much drag than before,cheers brilliant video. ,Roly🇬🇧.

Reminds me of recently discovering that modern oil based enamel paint not only doesn't flow properly below about 68F, it doesn't dry properly either. Apparently this is due to using lower volatility (low VOC) solvents in place of Turpentine. A heat lamp got it sort-of cured; good enough. Until Spring, when I can strip and repaint, my garage door will look like shiny molten wax.

[@electricboatal]

Hey guys, I have experienced this exact phenomenon working with West Systems epoxy in the cold. Typically when it is cold the moisture level is low but you are working close to water and it is probably why it is getting milky. I solved the problem by making a work area out of plywood and put a small heater inside. It is a lot of work but you will get good results. I don’t think that you would have lost too much strength from the milking but it isn’t worth the risk. You will figure it out I’m sure. I really like the multi motor drive system and it will definitely be useful for controlling the boat in windy conditions. It should be a bonus with the regeneration aspect. Good luck and Merry Christmas from Virginia, Your Pal Al

[@johnplump3760]

I have to agree with you and the other comments. For the epoxy to “kick-off”, the temperature has to be higher. I am not sure what it should be but I would read up and build a tent with a heater. I have watched to the end of Part # 1. I hope that you have read up to find the temperature that you need for the epoxy to start curing. Good luck. You don’t want the drives to come off. I also look forward to the circuit for wiring the generators to the batteries. Are you going to have each motor connected to its own battery bank with the appropriate switches & relays or are putting it all together with the appropriate components. It could get a bit complicated if you decide to have it all in one?? Good luck.

The white is possibly the emulsion binder from the glass - vinyl and polyester, the styrene content breaks this down. With epoxy it doesn’t, and it can be white and milky. You need to use glass without the binder. Anything with chopped strand likely has it. WR and Biax wouldn’t need it, so suggest trying your glass without the CSM content. Good show!

[@mishnishfourseventy1]

Also comments on the temp - I don’t think it’s quite cold enough or wet enough to cause issues yet in Sardinia… I’ve glassed through Scottish winters and still had no issues once I figured out not to use emulsion bound glass with epoxy 😊

[@michaelburati6692]

Awesome narration, filming and editing work - not many channels can make so much work so interesting to watch all the way through.

After all the structural improvements? I'd still upgrade that liferaft, and take a long hard look for the weakest link.
