Tally Ho runs aground! Prop and gearbox issues. 

That's not disrespectful, it's simply true. The Tally Ho project has gone above and beyond to beautify the elements of the boat at every step of the way

No disrespect taken. You like what you see and enjoy the most. I’m the same but become more attached to this channel because Leo and the guys and girl show all the content 96% of the time unlike other channels who just put a camera up and leave it on Timelapse.

@@LunarEclipsism1 I totally agree. If it's true, you ain't braggin'

My boat is offended by this comment. She thinks she’s quite beautiful also ;)

No competition.

Easy fundraising opportunity. I'd pay a lot more to bop over to Bainbridge on Tally Ho than on a boring old WSF.

L O L

😂

😂

@@DontDrinkTheFlavorAid I think that's for mutiny.

That is also why the French wear brown trousers :)

God, that front door gag had so many of us palpitating unnecessarily. Great fun in hindsight, but way stressful at the time, lol.

Front door felt weird but I trusted Leo. The ultimate betrayal.

My opinion too!

Tally Ho knew that it was going to happen. She wanted to get it over with on a nice smooth bottom, rather than on a coral reef in the South Pacific!

I do this with new motorcycle leathers. I find it’s good luck to roll around on the ground before using them to get that out of the way

Like in the movie Galaxy Quest.

@@knlazar08amen! Well said!

Agreed.

Ditto

The good thing is that Leo now has verified performance data on the current config. That is, hull speed for a given prop size/pitch, rpm and gear ratio. It’s clearly hit near max hull speed at a shade over 8 knots so the current prop is working well and with lower gearing might be ideal. Notwithstanding that larger (current) props are typically more efficient and Tally Ho’s prop aperture has been made to accomodate the larger prop, the prop engineers will no doubt provide optimum combination advice. Me - I’d swap the box if the calcs come out favourably for the alternative ratio if available.

Box.

Shouldn't it require replacing a gear and not the entire box?

agree with you.

I'm guessing that they can change the GB without lifting the cockpit. It might be a bit tight, but it will be a good test of the engine room design.

Also, if the whole system was designed for 2.5:1, this prop issue might not the only issue. Better to fix the root cause and avoid other unintended consequences, that could cost more in the long run. You’ve come too far to “cheap out” now. My dear old dad taught me that the definition of Boat is “a hole in the water, surrounded by wood, into which you pour money.” Edited to add: she’s a beautiful boat, and you and your team have done a wonderful job on her!

I agree. The appeture in the rudder is also made for the larger propeller so i seems like the best choice to keep it. I would also assume that the larger prop would work better when using it to generate power when sailing, which the hybrid drivetrain allows for.

@@meldert would there also be a loss of propulsion if it was switched to a smaller prop, even if it were spun at a higher speed?

Yes , doesn't she slip through the water beautifully ! I too was noticing how full the shape is at the beam going aft and yet she is really light in the bum - releasing with little drag and as you say - no wake astern . Beautiful higher efficient hull for such a heavy vessel . All the wake seems to come from the bows and it's small and short wavelength. I can't wait to see her really sailing in a breeze.

I have been motor boating for 45 years and never run aground so wtfu are you talking about.

@@BigWater59 Motor boats don't have 7 feet under the water line.....oh, and as the video said....LIAR!

🤣

That’s probably the best idea, and when you have it disconnected from the prop shaft install a spare toothed drive belt.

And if you designed the prop for that ratio, it'd be nice to stick to the design and not have any other unforeseen issues.

16:32 before deciding, consider which strategy will work better for generating electricity while under sail an light winds. Extra drag near hull speed might improve downwind stability, might it not?

True, but agonizing do over.

Which option gives Tally Ho more power and potential control (ie: safety) of the boat and crew? I would presume the larger prop but I'm a novice.

Aye aye!

bloody well proper, time to walk the plank laddy my boy who ever grabbed 2:1 inventory and the installer not cross checking gearing ratio needing to be 2:1.5 Cancel Reply

Yeah Rusty! Kind of like building a house. You walk the rooms on the ground and they seem tiny. Lay it out on the deck and they get a bit bigger. Put up the walls and they shrink again. That's where both design and construction experience come in, which keep you from freaking out at each stage. Also looks bigger below decks than above, I imagine. OK! Enough of this motor crap; let's hoist some sails!

Right? She looked huge up on the hard, and tiny now that she's wet. Reminded me right away of the old verse "“Oh God, thy sea is so great and my boat is so small.”

Boats are always bigger out of the water ,when you launch them they always seem to shrink a bit 😂😂😂believe me

​@@simon-oy6umAnd they shrink again offshore in heavy seas.

So Bountiful

Incredibly beautiful!

Agreed

Not to worry. She's a boat and constant repairs are just part of the game! 🙂

@@knlazar08 Absolutely true.

I agree. Is not the manufacturer responsible for this “mistake.”

As I understand it for a for displacement hull a relatively large diameter propeller turning slowly is more efficient than a small one turning fast so yes its better go for the lower ratio gearbox . (might not apply to a planing hull )

​@@henrymorgan3982 "Communication error" sounds an awful lot like someone requested the wrong box. These things happen on big projects, just gotta grit your teeth and rectify them.

@@henrymorgan3982 The manufacturer has probably taken responsibility for the miscommunication, or at least offered to swap the gearbox for a reduced fee, hence Leo saying that it's cheaper to replace the gearbox, but it takes more work. It's not exactly the manufacturer's fault that the gearbox ratio was spotted at the time it was in the water, that could have been spotted much easier (but it's also understandable that nobody checked this particular aspect).

​@@isfiyiywafibc6qaiiiiiiiiii570a large bronze feathering prop is an expensive bit of kit, there's not much economy of scale in that sort of thing, while all sorts of machines use a gearbox, without looking it up I could well believe it is simply cheaper to buy a new gearbox than a new prop.

I've seen other sailors attach a short stick to the bottom of the drone to make it easier and safer to catch.

Did you notice her wake? Even at 8 knots she wants to go faster. I can feel it right through the screen!

Tally Ho, 2027! I'm going to put money on her winning. I'm also going to attempt to buy the failed capstan top casting if possible. Windy Hill Foundry is selling it to compensate the volunteers that cast the new top cap to replace her solidly rusted old top cap. If I get it I'll make a giant clock out of it. It will be the only one in the world!

@@knlazar08 Should make a nice clock that will never crack :) We tested it for cracking with a lot of bullets :)

Measure three times, cut once. You just make sure the cut is in the right place. At times it is hard to see holes put into large sections of lumber that were selected carefully to be continuous pieces.

I remember watching Leo cut the keel (with a chainsaw, as I recall it) and just wincing thinking he'd make a drastic error. Boy, was I wrong! But like you I'm amazed how freely they cut holes and trim all their fine woodwork.

It might seem freely done but it's not. Triple measuring and deliberating isn't so captivating to watch so we don't get to.

@@Grandroborox - I mean, of course they’re triple-checking every measurement and are even using jigs, as in this example, to guide them. But there’s just something intense to me about committing to a cut like that. For instance, the decking he went into was so lovely and had already had so much time put into it, with the boards lined-up just so. Needs must and all, and an unlikely error can be remedied surely, but it’s still admirable to me for whatever reason. It’s something like carving the ear on an otherwise finished marble statue: the tension isn’t so much about the risk of a mistake but how consequential such a mistake would be. For some, even if the risk of it is minimal, the enormity of consequence may stay their hand or at least give them pause.

Sounds like you can feel it through the screen also!

Does the electric motor go through the same gearbox? I'd want to test the electric system as well before making a decision.

@@ColinWatters Surely it does. There is only one trans.

@@ColinWatters looked to me to be on the output shaft side of the gearbox and separately controlled, which would mean that the electric drive and sprockets are matched to the current prop.

Well that's me covered then because I ran aground last night. Went to drop the hook and it would not run out. Then I remembered I had just had some work done on the rode and I guess the guy that did it didn't stow the chain neatly enough and it got lodge inside the hawser. So had to put her on the beach in a flat calm falling tide for the night. Consequently, I couldn't set the anchor properly and when the tide rose at 2.00 this morning we went off on a little wander amongst the other boats. Managed to re-set the hook but then found that when the tide returned mid morning, I couldn't get of the sand and while it had been like a mill pond last night, not so this morning with a stiff onshore breeze and a considerable chop driving us father into the shore as the water rose.. Eventually managed to physically heave in enough chain to enable me to get into deep enough water where I could use the engine to rip it out of the sand and motor out into deeper water where I was able to eventually get the anchor onto the deck. Sailing single handed has it disadvantages as well as its benefits lol.

Or at least, humiliated. In 50k NM I grounded twice, both time up rivers with shifting, unmarked sand bars.

Good point!

The gearbox doesn't matter to accessories that drive off the crankshaft, like Tally Ho's. Driving stuff off of the gearbox, like PTO shafts driving hydraulic pumps and such, then the gear ratios would matter a lot. You can check that out on the Fabrats video building a wrecker. They drove the hydraulic winches off of the transfer case's low range gears and they could pull a house... but only at about one foot per hour! 🙂

Go back and watch the second half of episode 115 where they uncrate the engine. Leo pulls the cover on the hybrid drive system and talks about it. It looks a lot like the timing belt on a DOHC V6. The PRM hydraulic gearbox that gets bolted to the diesel output can be supplied with different gear ratios. But that gear ratio combined with the tooth ratio of the drive belt pulley ratio will have to align with the speed range of the twin 10kW motors. So I think that he is stuck with the gearbox ratio that was supplied and will have to match the propeller to the hybrid motor and not the other way around. But for sure it will be fun to see how they resolve it.

Shirley he only needs to change one gear in the gearbox? And stop calling me Shirley!😂

@@markrainford1219have you ever seen a grown man naked?

I hope he does make that choice, but you may have noticed, he gave a heart-like to one commenter who made the case for a prop change. That troubled me a bit.

@@llagas6307 I think that he was just be gracious. The "gearbox" vote is overwhelming!

I was wondering about the same.

might be even less of a hasle if the gearbox is just one single unit they can replace, then it would only be a problem of dicoupling and hauling out the old one and reinstalling the new one, but if the space around it wont tollerate that it might indeed be posible to swap gears, if the gearbox has enough internal room to allow for a bigger gear

You could even swap the gearwheels without taking the cockpit out. I'm sure Patty is our volunteer for this😂

@@jerryf609 Looking at the innards. not a simple swap. this unit has a clutch pack on the input shaft, its not clear if the shaft is splined or pined.

This would be my choice as well.

Yeah. I’m curious why the gearbox isn’t the one they spec’d originally. He said miscommunication but it’s very vague.

I think this is the wrong way of thinking about it. I don't think Leo ever said that 2.5:1 was a highly intentional design choice. It's possible they could pick from a range between N and M where both 2.5 and 2 are within that range and where there's no advantages or disadvantages to picking 2.5 over 2 except that they had gone with 2.5 and designed the propeller around that particular number. It's also possible that 2.5 lead to a cheaper but still good design and that 2 would have been more expensive and marginally better. Now, granted, it may well be a kludge in the end, but I don't think it's fair to say that changing the propeller is a kludge until you know all the facts.

I wonder if changing the gear ratio can be done by just getting a couple of different gears from the manufacturer and installing them in the transmission box they have.

​@@davefocgood thought !

Changing the gearbox to the original specs may well increase the electrical output of the generators when they are being driven by the propellor (using excess sail power during favorable wind conditions).

Avoid doing that in Hawaii. They'll drain your whole family's bank account and sink your boat.

Yes I was imagining all that beautiful paintwork being scraped off.

You never worked on a boat before.

It's ok if she runs aground, because of how she's built. Not much damage can happen. It's when you're stuck and the water goes down that things get risky. Also, she has a long time before she's out of sea trials. No voyage any time soon.

Just think of it as Tally Ho remembering that time back in the 50s when a grounding ripped her whole side open. She knows that boats always run aground, and she wanted to get it over with easy, so that the coral reef doesn't happen again. Boats might be inanimate objects, but they still have feelings. I believe that anyway. I've had too many motorcycles, planes, and boats with personalities to think otherwise.

I hate to think of all the work to get that cockpit back out. I would assume the engine has to be lifted also.

@@moebeddah2288 Another, may be huge variable which I was not thinking about, is the Hybrid/Electrical system that was added to the Diesel engine.. This might become a show stopper to replace the gearbox with another ratio..I am sure this Hybrid feature was designed to "fit" the engine including the 2.0:1 ratio gearbox..So I overlooked this feature, my bad... I am sure that Leo in talking to all the affected engineering sources, will come up with a right decision (whatever it takes)

I take it the tacho is calibrated?

Yes. In a year, all will forget about it. Except Leo of course!

@@fransdriesen1311 Frans, I don\t think the manufacturer would design the Hybrid set-up too only be used with a 2 to 1 ratio gearbox. This will limit the use of this system for a lot of end users.

Have a great video

Hello farind

Here here!

A little paint off the ballast keel is no big deal.

Depending on the drone model, I would also recommend inverting the drone immediate after "catching" it... Several models will immediately stop the propellers when inverted.... Model dependent, of course...

A good way to repurpose metal mesh fish cleaning gloves, which wouldn't be a bad thing to have anyway..

Or don't just don't touch the props 😂

@@d_fresh1169 big no no for the motherboard apparently, only the first mini was designed for that.

looks like an autel evo 2 which if i remember correctly has the auto-shutoff functionality.

Sorry - I've been following Leo since he arrived in Oregon and this is my first comment. I posted without finishing my comment. What I am implying as a retired Professional Engineer they optimized the charging with the 1:2.57 ratio, and THEN optimized the propeller at that engine/generators output and Leo's desire for a smaller opening in the rudder... I also think they could lift the engine from the deck beams enough to switch out the tranny AND the pulleys/belt driving the generators/motors - keeping the prop as is.

Heres another not related directly to sailing,......there are 3 types of people in the world............those that can count, and those that cant

@@bonvoyage5377 I got to write that down.

Your quote is that of a funny realist. I’m the gloomy idealist type 😅 esp these days

Yeah, Trevor Bauer of the Cleveland Indians during the 2016 ALCS. We don't need no stinkin' pitching.

I don't think there is any other option on a boat, though. Getting the drone to land on a moving platform is not within its operational capability. I guess you could use a net or something like that.

Maybe you need to look at the Volvo ocean race they were catching drones out the sky with boats moving at 20 knots ,yes different drones but also the boats were bucking around and there was several boats doing it sometimes every day . Bet the first few times it was as sketchy as but I bet by the time the planet lap was up confidence in doing it was just like doing anything on a boat , would suggest the catcher to be wearing gloves though that alone would make a world of difference if a prop was accidentally bumped .. but yea go watch some of the footage especially the southern ocean roaring forties ferrous fifty’s stuff the cinematography is spectacular and all out of reach of any civilians chopper and one of the sailors on board title was obr on board reporter his only job was there to edit collect and publish photos videos and document story’s he was not allowed in put on sailing turning winch handles r running the boat the only job was reporting life at the extremes . I doubt Leo will push the boundary’s these guys did but hey you never know you don’t push the envelope you don’t get the shot and practice makes courage to go the next step .. I’ve seen other tests done yea these small drones might hurt you a bit but there not going to kill you . PSs a mate of mine was on akzo Nobel broke the mono hull speed record for 24hours 602 nm that record might stick for a while that’s a lot of miles in 24hours average boat speed is 25 knots
