Our Catamaran's Drive Train - No sail drive here //Complete Catamaran Build

It has taken some time to decide on the appropriate drive train and propellers system for our Catamaran. We tossed up the pros and cons of many different propellers and we are so happy with our choice.

we must be rooting for you and Janet because, for myself, i have watched all your episodes be they thick or be they thin; interesting or bored out of one's mind. What i do know is that for everyday that this build goes on, your fortitude (and Janet's) is constant and emotions must seem like an ebbing tide! All i can say here is........... **** Push on Mates ****!

[@latitudeash]

The leader poker idea is really unique. Never seen that before.

[@nena4215]

Now that’s brilliant Ross! Oh boy though, that’s going to be some ruff boat yoga up there in the side of your steps, don’t know how you do it!!!

[@Kezzht]

Doing a great job Ross. Have been watching your progress for a long time now. All the best mate

[@nez3009]

I didnt realize I'm so far behind. Looking good.

[@kenbaustin4533]

Love that you kept the photo bomb in!

[@LifeOnTheHulls]

Josh is such a goose too.I just wamna cut his mullet off.

[@berikco]

Nice work Ross, and this is easy to maintain i think, compared to saildrives.

[@LifeOnTheHulls]

After hearing so many sail drive problems there can be no better solution I believe.I didnt have a choice in the matter ,but a friend if mine has just spent a mint fixing both of his sail drives and I honestly don't think they are a good investment.Rossco

[@charlesc.6767]

Ross, You probably already know this but when i put new shafts in my sportfisher the mechanic re set the alignment a couple days after after we launched to let the hull stringers relax to its final position in the water. He even checked that the prop wash from both props were even under way.

[@brianstyrczula9466]

Hole Lee Crap, looks like it might flowt. Well done Bro.

[@colinhill5771]

Love the ladder boxes! I hope you will show more on the prop shafts

[@LifeOnTheHulls]

Thanks Colin.There will be much more of that for sure.Ross

[@latitudeash]

Cleaver bit of kid that coupling. I bet it was expensive…beautiful engineering

[@LifeOnTheHulls]

It is a piece of British quality work mate.Besuitful piece of kit the Sigmadrive

[@frankstocker5475]

Consider installing a couple removable handles to help people climb the ladder after swimming.

[@LifeOnTheHulls]

There will be some sort of rail available.Cheers Frank

[@jkstricko]

hey Ross The force that enters the transom in a following see is huge. Beef up the lock that holds it all down. Crossed the atlantic and needed to make repairs on the run

[@LifeOnTheHulls]

Yes mate I am beefing it all up as I fully understand yet couldn't calculate the forces with which I expect it to handle.Cheers mate.Rossco

[@bencampbell2407]

G'day Rosco, I'm with you mate, at 40k each motor, id be pissed off also! Not good enough!

[@matswilliams1058]

Wow, that's an overwhelming amount of parts and pieces to put in place and all with some kind of challenge. Impressed by your abilities! (Couch sailing seems more and more natural to me).😅

[@bobthesnobscotland2821]

Cheers Ross

[@mikestickersm3mxb279]

The amount of thought and forward planning is amazing Ross, fantastic

[@supergarbonzo4843]

B-E-A-U-T-I-F-U-L

[@LifeOnTheHulls]

Thanks mate

[@ianhodgetts8266]

i noticed that when you extend the ladder, you are hard pressing against the suger scoop.

[@edwardhaigh4249]

Love ya work Ross, I'll send some pics of my two builds what would be be best way to send them to you?

[@MVSheKon]

I started to itch just watching you grind out the ladder opening. 😖 And I liked it! 😆 Nice work Rosco. Cheers mate. 🍻

[@LifeOnTheHulls]

You are a sick man buddy.Getting itchy from 10000km away.

[@MVSheKon]

@@LifeOnTheHulls Just gettin’ itchy to get back into it myself. 😆 Been off the grinder too long now. If Mother Nature cooperates prolly about another month. 🙏

[@ehrenfriedklemt4031]

[@chantedefelepe]

Great work mate

[@nickcooper14]

Mate, looking great, it will be easier to harvest your sea life seeing as the ladder is on the lid. Nice design. Even though it sounds stupid to use anti-seize on a compression fitting do put a smear on your shaft and the taper. You always need to clamp the length plus a smidge of the diameter of the shaft. Like a bolt, the nut is the thickness of the diameter. We use these couplings on most of our pump shafts and the bite like a bitch. Probably have your machine shop make you up a wedge shaped tuning fork like a ball joint tool. To make separating the shaft a few years later down the journey. I didn’t notice if the tapered section had a couple of taped holes to make extraction easier. Or run a tap through 2 or 3 of the bolt holes. So if 8mm bolts run a 10mm fine thread and have some bolts handy to seperate it🤙🏼🤙🏼🤙🏼

[@ghostflier520]

Gorgeous

[@donaldwright6613]

Great job Ross.👍⛵

[@LifeOnTheHulls]

Thanks Donald great hear from you.Ross.

[@normanboyes4983]

Nice work Roscoe and you are right, it is so disappointing to see the corrosion on the gearbox output coupling.😳😊😊

[@LifeOnTheHulls]

Ridiculous mate.

[@medickaisu]

I really like those ladder boxes. That is slicker than snake snot.

[@martinneubert4068]

Awesome work Ross, as always. Nice detail with the latter boxes. All the best.

[@geraldtribbe6363]

Another nice feature about the extended hulls is distance between prop and ladder.

[@mischafellner8943]

I live in California. I appreciate you pointing out a good company. Not all are ( or can be) great. It’s nice of you to take the time to point out their company and their strong points.

[@slimdavey100]

It’s coming together nicely remember when the moulds where delivered watched every episode where’s Johnny these days ⛵️⛵️⛵️

[@gillyb333]

That's a tedious job but at least you have it all aligned Roscoe well done my friend xxx

[@1jeffcan]

Very clever. The ladders are brilliant. It amazes me too that a 30mm shaft is enough to drive the prop.

[@LifeOnTheHulls]

Cheers Jeff, mate you know it.Love it mate,Ross.

[@Cameron-ur2tk]

Is there going to be any water tight bulkheads within the sugar scoops? That ladder function and looks couldnt be any better, nicely done.

[@kev.fwestofireland334]

Cheers love the ladder boxes. Very neat

[@LifeOnTheHulls]

Thanks Kev.

[@DWAJarrett]

I finally figured it out….. thoughts and design are only half the work of a monohull ‘cos it covers twice the work 😁😁 Beautiful custom build Rossco.

[@philiphemphill4980]

Always good to have a new video Rossco your eye for detail and always thinking of future needs in the build and fixtures is amazing it is going to be one beautiful craft can't wait for the next video cheers mate

[@mkllove]

Ross, I heard you mention the rudder, linkage, rams etc were all located under the steps along with a manual/backup option... that seems to indicate the back area under ladders will remain unused or inaccessible ? What if you made something like a drawer or custom fitted tray to slide in there, but still be pulled out over steering gear ? You could store less often needed items like engine oil, belts, fuel conditioner etc...

[@peterplouf2836]

Curious why the Constant Velocity joint that is so common on FWD cars is not seen in marine drivetrain applications. Seems like the ideal way to deal with the changing geometry of the engine/driveline as the parts settle with use and time.

[@Thealder07]

Hi Ross, it is so un recognisable stern from a month or two very well done. It looks awesome

[@LifeOnTheHulls]

Thanks Dave,it is really taking shape now.

[@nigelmorgan3449]

Nice work Ross it’s coming along fantastic …

[@rl3898]

I so agree Rosco, the standard of, and mix of, materials YM use makes their engines disintergrate into rust and corrosion in aa few years. A good mate with a YM in his cat used the remaining clean engine oil of a service oil change and brushed it over the engine to reduce the rot. Looking at your shoulders being at water level as you worked on the ladder space, are you sure you could lift your leg 1 meter to get onto the ladder?

[@1svsoulmate]

Pretty sweet Ross. The ladders and the ladder boxes are awesome and there is a lot of storage under boxes. Good for bumpers and light weight items. I'm not sure how you will access it though. I guess around the rudder shaft. As always thanks for sharing.🏝

[@LifeOnTheHulls]

Thanks Daniel, access will have to be around the rudder post so will be limiting.

[@stephenj9563]

Good episode Ross Great job on the ladder boxes

[@LifeOnTheHulls]

Thanks Mate.Cheers Rossco

[@rt17022]

Just wondering. When you are stepping up the ladder and reach the hands off area. Are you going to have a grab rail? I have a simular style ladder and had to install a strap to provide stability to make the final transition smoothly.

[@iknownothingaboutsailing5308]

😊

[@secretsquirrel6308]

Ross, we know yer not lazy. So was it you weren't sure of the ladder box design so you sorted it out piece by piece as you went along? You're a composite master so I'm trying to figure why you didn't build the box at the bench. Anyway, its a nice, compact design.

[@saulzain1957]

Great job! Are the rear ladders going to hang vertical when deployed or at an angle?

[@douglasrobbie9998]

From a design point of view, can we assume that the prop shaft will be able to be removed without dropping/removing the rudder?

[@jimlofts5433]

ahhh hindsight - how much easier would it have been if the box had been pre-prepared and glassed and then it could have been screwed in from the top

[@nedwphillips2126]

They look fantastic mate, Btw have you considered a taper on the bottom part/transom to a slightly inwards manner to the bottom of that hole maybe 2-3 inches (taper length), as it will support those ladders once in the open position with reenforced surface that matches the ladder angle eh (hope that makes sense) Ned

[@LifeOnTheHulls]

Hah,Ned, I am way ahead of you.You read my mind.Exactly what I have done.It-s superb.Cheers Rossco

[@WillPittenger]

Is your prop also variable pitch?

[@williamfreeh1198]

your audio volume is all over the place.

[@kscipkkkk]

Why so much glass inside and out for a piece that will never see stress or weight?

[@LifeOnTheHulls]

Ladder box will bear the weight of the ladder when in the hatch with someone on at at times,other thing we considered is the incredible forces that a pooping wave that will drive into the box under the hatch, not sure we can even imagine or calculate that stress but it will be considerable .I am under no illusions after having worked on dive boats and sail oats that have leaking transoms and ladder hatches.My worry is the integrity of the hatch locks and hinges that could easily be blown off in such a situation.Cheers Rossco.

[@kscipkkkk]

@@LifeOnTheHulls Trying to keep your boat on a diet so your dive platforms aren’t under water from the weight. I’ve watched from the beginning and there is nothing light weight about this beast.

[@latitudeash]

I would want to replace that rusty steel, better doing that now than messing with it at sea. I suspect it will rust to bits with the see air. How can they fit such rubbish steel. That’s crazy.

[@rayboucher479]

Why ? $10 exactly like car manufacturers .

[@LifeOnTheHulls]

Very true.Poor choice of materials.
