- It is always the detail that makes a project come to life. To build a Massive Catamaran you must pay attention to the little jobs and there are hundreds of them. The years may go by fast but the detail is so important and the progress is the payoff.
Our CZcams build series is all about what it takes to build a Catamaran from Scratch. There is so much detail in a build of this size and so many different techniques involved in bringing her to fruition. I trust you will find something that may help with your current or future project, repair or dream boat build. If you feel there is value, please let us know and comment so we can continue to produce content worth your valuable time.

Hatches are a work of art.
Also the best memory of all time: Ross in his fluffy onesie pyjamas while polisinh the mold 😁
That was a very funny moment.Worked so well too, no stick ups on my mould when I demoRlulded her.Rooss
Sunday is Mother's Day!!!!!!!!!!!!!!!!!!!!!!!!
For sure.How was your week mate.
Greetings from Texas mate. This is my favorite channel. As a craftsman myself and one who likes things perfect I can tell that you are too. This will be one awesome boat when she gets on the water.
Thank you mate, really appreciate you watching our series and your thoughtful comment.Rossco
I'm reminded/ remembered the engine bay modifications from a few years back!
That was crazy but worked out so well after a tonne of work.After watching Zatara's engine mount issues with their new engines, I can totally relate.Ross.
I rush home every Thursday just so that I can watch on my TV at home. Keep up the great work my friend.
Good onya Mitch, no rush, will always be here.Thanks though, means a lot.Ross
The davits are looking great. I’m almost forgetting how bad they when you got the.
Yes mate, they were trashed and delaminating.
Not much longer and you could splash her and finish floating !! Been here sinch the beginning but my screen maned changed a while back. Much respect to you my friend !! Doug Doty in Florida...
Cant wait
Thanks so much for sticking with us.
So much going on hey Ross, as there ALWAYS is, ha!
I reckon that we have exactly the same sole/deck latches, which I thoroughly checked out with mine and they are definitely legit. and I am very happy with them.
That is great to hear Bruce, hope you are nearing a launch buddy.
Very nice work.
And some nice details, love it 🙂
Have a greate weekend.
All the best.
Thanks Martin.
Keep it simple Ross, forget any systems that are complex. You will thank me
Totally agree , the simpler the better.Ross
It’s a little late for that idea!
Well let me be second then, doing a great job Rossco
Cheers mate, great to hear from you.
Waa, I hoped to see more of the muffler installation.
Anyway, crack on. Looks a treat.
Thanks Richard, might have to wait a little, sorry.Rossco
Love your videos mate. I wouldn't trust all those hose clamps you use they fail I've seen it on so many other channels
Thanks Lucas's, I reckon I will replace all hose clamps with single bolt units before launch.
I have always believed copper lines , especially soft copper is only safe to use when the pressures used are under 100 psi. Typical hydraulic pressures are 2000-5000 PSI . Russ maybe you could explain a bit on how your system works and the pressures your hydraulic operates at. Things are coming together so fast, you'll be in the water before long. 🎉 CHEERS Steve h .
Im sure ross read the manual but nonetheless soft copper is used on most refrigeration and hvac equipment and modern 410a systems are often pressure checked 300 psi. Copper nickel lines used on vehicles car brakes easily handle 2-5 thousands psi.
Implicit instructions from hydrive for 1/2 inch copper lines.Important to note that system is not powered by power assist, I guess this is where pressures are lowered .Tube is rated to 758psi and burst pressure at 4000.There are currently over 600000 hydrive systems in use worldwide, so I guess they know their business.Most hydraulic steering systems on boats this size use vetus or seastar nylon tubing, I am more happy to use copper however was a challenge to instal.Cheers mate.Rossco
Good to know and too hear! Thanks for the reply. CHEERS Steve h
I'd love to see a segment where you talk about the various finishes you've used (Gelcoat, flowcoat, etc), the differences between them, where and why they're used.
Me too, always repairing my dinghys
Looking good Ross.
Thanks Jeremy, have a great weekend.
Magnificent as always.regards
Cheers mate, had enough rain yet.
@@LifeOnTheHulls certainly have be glad when it's gone.
Hi Rossco,
I would hate that raw water inlet route, with todays plastic rubbish and the warm seas increasing weed debris you are asking for real trouble.
I strongly believe that one should fit a straight inlet pipe to the filter from the seacock with clearance above the filter to poke out debris quickly when a filter inlet pipe blocks.
Years of use have proved me right, on boats that do and those that haven't, you would have a hell of a time removing that long inlet pipe and getting compacted rubbish or weed out of it.
I reckon you are right, I will look into having it closer and straighter route to the through hull.Thanks mate.
That kind of markup sounds about normal with burnsco stores in nz
Normal in a chandelry worldwide by the looks of things.Ross
On my boat the vented loop on the inlet side after the seawater pump, but before the heat exchanger. No vented loop after the heat exchanger it just drains straight into the elbow.
Our engine is below water level so vented loop must leave heat exchanger to loop at least 40cm above water level then to elbow, otherwise risk of back siphoning of raw water into the engine block.Our elbow is now 35cm above waterlock with new exhaust riser.

Well I have to comment because there is not one yet.
Good man.Thanks mate.
Will you be fitting lighting in the enginerooms? LED strips seem to be all the rage and work well and economically.
Hey Roger.I defibately live the led COB strip's they offer a shafow free lighting, Not quite sure how I will mount them yet as I need to install insulation throughout the engine rooms.Cheers Rossco
Roscoe- you should know by now there are no little jobs, the one hour job takes half a day and the two hour job takes a week.🤣 Raising my eyebrows here in the armchair watching the copper work on the ‘hydraulic’ steering system. I know you will have researched the hell out of it - BUT is this copper piping on the low pressure telemotor side of the system (control) as distinct to the high pressure (power) side?
Thanks Norman.I have followed the Hydrive instructions to the letter including tubing.There are thousands of hydrive systems using copper tubing.All are more than adequate.Most vetus and seastar systems use nylon tubing, pressure is not that high.Copper tubing is rated well over 758 with burst pressur at 4000 , hoses are 1000 and fittings are over 1 thousand.Hydrive won't warranty a system with nylon tubing.Ross
COURT drained me and yet, still no positive word.
Take care mate.
🎉
Gday Ross still sanding the schionning wilderness underneath ready for final pain one outer hull faired heaps to go I have those hatch lock but the previous owner bought original ones from america can take pics of one if you want or my wife Jeanette will be home to dapto in a month from here in wa and can bring you a spare one. Did you get a deal on your batteries or not as the company is here in Western Australia and looking at batteries for sizes cheers greg from dapto
Good to hear you are moving forward, Happy to hear about the latches also.Ross
What sort of pressure do the hydraulic lines see?
Fairly low for those sorts of systems generally.
Have you worked out what your displacement will be?
Boat should come in at 8500kg dryweight,
Little bit at a time
Indeed.
If you could do it all again, would you build it out of another material? Just wondering cause i bumped into a CZcams channel that is in the proces of designing their own cat but out of aluminium with a very different design then yours, "Sailing SV Delos".
Personally I love the idea of an aluminium cat, but the insulation required extent of outfitting is 10 times more difficult, and cost is extensive, I do like the fact it can, although will never be recycled.The fabrication of grp for me is far easier and although I can tightly weld, I would prefer to work with foam as it immediately adds insulation and floatation. I have seen delos and a number of others but am more than happy with our Cat.
Seems so near , but so far 😃🍻
Getting there so much work.
If you've got Zach for a couple of weeks, do you want to borrow my whip?😊
Might need it mate.
👌👌👌🤟🤘👍👍☝☝🙌🙌🙌✌😎
I'm rather surprised that you used copper lines for the hydraulics. Here (US) almost all hydraulic lines are steel with the exception of flex rubber hydraulic hose which also has braided steel in them. Great Job otherwise.
Doesn’t really surprise me that brass and copper are used. Steel would start rusting the day he splashed and the brass and copper although more expensive than steel will last for years with flair connections. Much less expensive than 316.
I had the same thoughts, not sure I’d want bare copper lines. The hydraulic hoses you refer to are easier to install, and much more durable to everyday life on a boat.
Lovely job so far mate. Rather concerned you've used copper pipe for hydraulic lines. Garmin SmartPump specs hose with a minimum pressure rating of 1,000psi for your hydraulic pump and relief settings on control valves back to the tank. Hydraulic hose was the way to go here. Plus all your valves and fittings are grossly underrated, wrong material and rating. Sorry.
Every hydrive system and that is thousands are plumbed with copper tubing Hydrive specify only copper annealed tubing in all installations with larger boats requiring stainless tubing with runs over 60mtrs.All flared fittings are rated to 1000 psi and hoses are all 1000psi rated.
@@LifeOnTheHulls Yeah, I'm sure you've done your research. ASTM B88 Seamless 1/2" copper annealed tube has a working pressure of 758psi and actual burst pressure of 4,535psi. Even the outboard steering motors have a MWP of 1,000psi. Having briefly looked at the specs for various HyDrive and Garmin hydraulic steering pumps the info on MWP is pretty scant. Having worked as a pre-commisioning engineer in the gas industry for 30 years I'm a bit OCD about specs and MWP and test pressure calcs. I'm sure it'll be fine if '000s of boats are all kitted-out the same way.
I am sorry, but the way Australians pronounce ‘deck’ makes it very hard to hear a sentence such as “I have a very dirty deck” without giggling. Great videos btw!
So funny mate , glad I am not a kiwi, 10 times worse.
I bet!
Those hatches will never look cleaner ever… lol..
Once polished they will stay cleaner.
Ross sorry but it always better with a Woman Touch on any Work they Do.
That is so true
