: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey April 07, 2016, 23:31:05
At this time of year we are officially half way through Autumn but this year we’ve had a record breaking summer and the extended spell of great weather has distracted me from my latest project. It has started to cool down a little over the past week so I’ve spent a bit of time back at the bench.
I had decided to build a model of the Karetai, a 1970s diesel harbour tug from Otago, here in New Zealand. It is 28.6m LOA and is quite a nice looking boat. There are several very nice models of this tug around the country (especially one by Vanya & KiwiNZ on the forum) so I thought that I’d give it a go too. Not a motored version this time, just something to gather dust on the shelf.
In 1974 the Otago Harbour Board ordered 2 identical tugs, designed by Eken & Doherty in Sydney and built by Sims in Dunedin, Otago. They are hydroconic hulls with twin ASD drives and have very clean lines and uncluttered deck/superstructure areas. My last build was a hard working ocean going tug that was cram-packed full of equipment and this build has no winch and very little deck gear – yahoo!
The Rangi was built first and then the Karetai was delivered in 1976. They served Otago until being sold off to Australia a couple of years ago.

Although they were supposed to be identical, some design flaws were ironed out in the second build and there were some minor cosmetic differences. Apparently one engineer was a stickler for cleanliness and his boat was kept in showroom condition while the other had a slightly rougher life. Rangi had the design flaws and I’m betting that it also had the scruffy appearance. When I was young describing something as ‘a bit rangi’ was a very derogatory term for poorly made or maintained, shonky or shoddy. The first stages of my build were ‘a bit rangi’ too.
The developers of the hydroconic hulls were very protective of their designs and didn’t let any hull drawing out of their control. Now days these type of hulls are all over the place but back then it was all new technology so not many hull plans are floating about.

: sea monkey April 07, 2016, 23:36:39
I managed to find some reasonable drawings of the Karetai, drew up the hull and had the parts laser cut out of 3.6mm ply. Those were my first 2 mistakes.
Below: Day 1 and everything is about to hit the fan.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey April 07, 2016, 23:40:47
The ply I used I had picked up on special a few years ago (can’t resist a bargain) and it is hopeless: too flexible, very coarse grained, splinters and split easily, and warps in the slightest sunlight.
The original drawings I had found were not accurate, probably on purpose so that no competitor could use them. It didn’t become apparent until I started sheathing the hull – some of the curves were very clunky and the hull just didn’t look right with bulges and bad angles. After a few days it also developed quite a warp/twist and it took some serious clamps and about 500ml of resin to straighten it out again.
Then the crappy ply really came into its own and the hull needed about 7-8 rounds of filler/sanding/undercoat/repeat to even start to get smooth enough. Quite satisfying going at it with 60 grit, things smooth out pretty quick then.
So much for saving a dollar on the ply! Unfortunately I still have 1/2 a full sheet of ply left so I’ll probably go through this all again sometime.
That’s when I realised that I must be making the Rangi instead of the Karetai so the subject was changed 2 weeks into the build. I'm now making the Rangi.
I was too embarrassed to photograph the hull construction (it was sloppy workmanship) so in the next post I’ll jump ahead a couple of weeks to a slightly smoother, straighter, cleaner hull.
Below is stage 1 of the hull straightening, with half of the fibreglass bracing that went into it.

I also know about running into poor plywood. Like you say, lots of wood filler.
Your pictures are gems for laying the keel and on, thank you for sharing and
keep it up Sea Monkey.

After much filling and sanding I finally got the basic hull to a stage that I was happy with.
Still plenty of imperfections on the hull finish but nothing a little more filler and some 800 grit won't sort out.

You can see some of the areas that need some more attention.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey April 17, 2016, 00:38:24
I managed to make a major mistake on the stern and had to adjust the bulwarks. Luckily the fender housing hides most of the problem.

: VANYA April 17, 2016, 00:59:14
Steve,

Its only a hobby mate, not a race. At this rate you will have it complete but the end of May.

Must say it looks good, very good actually and that laser cutter has done a treat. Its premo work and after seeing the Seatow this one will be brilliant also.

What can we get to you to build next...

How about the Te Maru, the Japanese style tug from Timaru. That will be a challanging bow to shape. We have the drawings.

We were down at Dunedin Model Engineers on Saturday for their 80th birthday celebrations.Brilliant day.

Keep up the good work.

Hayden
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey April 19, 2016, 13:04:06
Thanks Hayden. Finishing this one quickly would allow me to start another before the wife knows I've pulled a swifty.
I do have something from Timaru on my wish list. Aorangi, Aoraki or Te Maru, whatever I can get plans for. Aoraki is a powerful looking beast and Aorangi is classic 60s look. That Timaru green looks good on anything.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey April 19, 2016, 13:15:31
Managed to get a few solid afternoons at the bench over the last few days and have got the hull to 95% finished.
Cut out the scuppers, added the cap rail, fender housing and bracing on the bulwarks (not sure what they are called) and hawser holes (not sure what they are called either).
And yes, the forward bulwark braces are supposed to be further apart than the aft ones.
The ply template is the base for the superstructure.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey April 19, 2016, 13:16:47
Only a few blemished left to correct and then onto the wet & dry!
: Re: 1970s Diesel Harbour Tug 'RANGI'
: VANYA April 19, 2016, 19:44:26
Hi Steve.
I think I can get the Aoraki drawing set. It is a chunky machine and plenty of modelling to offer for a good keen builder like yourself.

I have parts of the Aorangi drawing set but not keen to let them go as it is my ultimate bucket list build. There is actually one been stylised down at Otago Model Engineers from photos I think. They are after the colour match too.

Te Maru certainly would be different. Did we include a lines drawing with that bundle we sent up for your archive? Have photos also as now its all locked off and you cannot get near her for photos.

What is the length of the Rangi your building? 1/48th scale?

Hayden
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey April 19, 2016, 21:35:23
At 1/50 it's 575mm long. That little bridge/wheelhouse makes it all appear smaller than it really is.
I've got 2 more contenders ready and waiting after the Rangi – the old YTL James O'Brien (ex Westport) and the Parahaki from Whangarei (a monster). I'd be keen on the Aoraki drawings if possible, I could slip that one in next spring. How approachable are Timaru Port regarding photos?Only got the pilot boat lines in the pack you sent up.
Steve
: Re: 1970s Diesel Harbour Tug 'RANGI'
: VANYA April 19, 2016, 23:33:14
Steve.

My yacht club friend is a relief skipper on the Aoraki every somoften so I am sure I can get photos without going through the full induction/ worksafe/HSE rubbish that percolate through everything these days.

It is one vessel I have not examined in depth.Might be worth doing once for posterity just in case it gets sold off. Have the drydock photos from Lyttelton on last survey if thats any help.

Good that you are building a model collection of museum standard tugs and workboats.Impressive.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey April 23, 2016, 23:00:46
Not up to museum standard I'm afraid but each one seems to be getting a little easier to build than the previous one.
Have to secrete them around the house as my wife can't seem to understand why we need any more.
Anyway back to the build.
Managed to get the hull finished, undercoated, wet & dry polished as smooth as a baby's bum, and prepped for painting.
Added some anodising plates although I guessed at their placement as the only photos i have seen of the boat out of the water are when it was being repainted and the plates had been removed.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey April 23, 2016, 23:10:09
Also added some details to the hull.
I had brass etched some fender tie loops. They are 2 separate pieces – the hull plate and an eye that slots into it and through the hull ply.
Worked out OK. I attached the bases for the bow and stern fender straps.
Don't worry about the rough finish inside the fender housing, it will be hidden by the rubber fender.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey April 23, 2016, 23:22:00
And scribed out the outline of the ASD hull section. The ASD plate has rounded corners in a square cut hole in the hull.
You'll never get to see these lines but at least I'll know that they are there.
Now ready for the paint job.
Over the years the 2 tugs have had several colour schemes. The hulls have always been mid blue and the superstructure white but the decks have been pale grey, pale blue, light blue and the same blue as the hull. The bulwarks have been white, hull blue, pale blue and light blue.
The funnels have been white, hull blue, dark blue and yellow.
Plenty of options to choose from. I'm tending towards pale blue decks and bulwarks (yes, that happened) and yellow stack.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: VANYA April 24, 2016, 00:31:31
Nice Steve.

The historical OHB clour have been dark.Royal blue with yellow I think.

They painted the tugs more recently that lightler blue but did not like it so much.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey May 02, 2016, 14:59:36
Thanks Hayden.
This next part – the ASD drives, was quite easy. I thought that I might have a try at 3D printing so I drew up the drives and tried to convert them into a 3D modelling program. That's harder than it sounds unless you're a tech savvy teenager. The initial 2D drawing was easy, knocked it out in Indesign in about 20 minutes. After much trial and tribulation battling with a 3D program (another battle lost in my continual struggle – man versus machine) I eventually sent it to a 3D specialist and he cranked it out in about 20 minutes.
Then off to Shapeways. For a test run I chose strong, white and flexible, hit 'print' and waited. Nothing turned up for 3 months, apparently it was lost in transit somewhere in Brussels. The help team at shape ways where very helpful and re-printed the file., however for some reason the file kept hitting a print error and failing and the final stages of printing. After a minor file adjustment and a change to polished, strong, white and flexible, the finished products arrived. 2 weeks from ordering to delivery in New Zealand – not bad. The finish is a bit rougher than I had anticipated and the material doesn't handle sanding too well. Not bad for a first attempt, and nothing that can't be fixed with a few extra layers of paint.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey May 02, 2016, 15:12:59
Getting the props printed at the same time was quite cost effective. Getting 2 brass props sent from Europe would have cost 4 times as much as the total cost of printing both drives and props.
I hadn't been able to find any pictures of the ASD drives on the actual boats, and as is always the way, the day after the drives arrived from Shapeways Vanya sent me a great photo of the Karetai in dry dock, with the drives in full view. Bugger!
I had made my main shafts cylindrical while the real ones are much more elliptical and only have 2 fixing points. They are almost like small rudders or vanes in front of the drives.. But if I hadn't just told you no-one would ever know. I'm sticking with my cylindrical versions as I can't really afford or be bothered reprinting them. Better luck next time.
After a few coats of undercoat and some extra layers of top coat they look OK. The props even spin freely. I'm satisfied with the result and know how to improve next time.

Extra fine Steve. I am very impressed with your tackling the drive gear and

Thank you Steve, great posting and all.

: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey May 04, 2016, 16:32:07
Thanks Michael.
In the end I decided to go for the mid blue decks and bulwarks. The OHB didn't use this scheme for long and it tends to camouflage the vents and deck equipment but that's how it is in several of the photos I have.
So now the basic hull is completed and I can move on to the superstructure.
The bow bull's eye isn't attached yet, just there for the photo. I'll leave the deck equipment and fendering till later and I always leave applying the hull markings and name until the very last thing – sort of signing it all off.
Plenty to do before then.

... a couple more.
The flash has made the deck colour appear yellower than it is. The colour in the first of this series of posts is correct.
The deck will have another few coats of clear satin once the deck equipment is installed.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey May 04, 2016, 16:43:57
And finally, a question for any Otago boys out there: Keith, Antipodes, Simon, Hayden, Delboy?
What are these?
Is it a valve of some sort behind the door? The only photos I have all have the door open and obscuring whatever it is.
And what is the safety valve/cut off towards the stern and what would the text around it say?
: Re: 1970s Diesel Harbour Tug 'RANGI'
: VANYA May 06, 2016, 08:32:06
Steve.
The item in front of the door is just a recess where the shore power connection is made with a heavy duty 3-phase socket. You can see a little of the cable in black.

The aft area of interest is a vent open/shut handle. Obviousy something to do with air suppression in time of fire etc.

Hb
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey May 14, 2016, 12:54:19
Thanks Hayden,
You're right about the shore power socket (only on the port side). The lever at the stern is the emergency fuel cut-off. One on each side. Got the answer from forum member Antipodes who is the OHB chief pilot. I'm sure I'll be asking a lot more questions as I only have limited reference of the boats.
In the meantime I've been making slow progress. The hull is pretty much completed and I'm happy with the paint job, only a couple of minor touch-ups required.
Now onto the superstructure.
I had the basic form laser cut and in theory it should have slotted together smoothly and quickly. In fact it took ages and quite a bit of interior bracing. I used ply 50% thicker than probably needed and had had it cut with the grain running the wrong way – it's 3 ply so bends better one way than the other. Getting it to comply to the curves required lots of cross bracing to bend around. I think I ended up with as much glue on me as on the wood. Once constructed I was able to cut out some of the excess bracing.
Here are the basic carcasses.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey May 14, 2016, 13:00:36
... and yes, I will have to cut out a section of the wheelhouse ceiling to glaze the windows. I didn't think of that one beforehand – Doh!
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey May 14, 2016, 13:02:36
I can never resist putting the pieces together to see what it will eventually look like.
Still plenty to do and it looks pretty rough at the moment but you get the idea.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: model tugman May 14, 2016, 13:44:25
Looking very nice,I like the laser cutting idea,I still cut 3 MM ply with a Stanley knife.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: VANYA May 15, 2016, 11:49:43
Steve.

Brings back memories if cutting out plywood for Karetai back in '87.  Also with a Stanley knife!

Are you going to kit out the wheelhouse. Map table and flag locker?

I will see if I can find the paper photois tonight otherwise I will photograph our one with the iPhone.

Whats changed in 30 year.

Nice.

Hayden
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey May 16, 2016, 12:40:41
Yes, George, the last cutting certainly makes life easier. Just another tool and making the most of technology.
Hayden: Hadn't thought about that until you mentioned it. Don't have any reference for the interior so was going to rely on tinted windows to hide things.
Had some time over the weekend and managed to give the build a good crack and added the lip to the top deck, some of the etched brass stairs, hand rails and deck plates/covers to the superstructure. Also cleaned up the surfaces and got a couple of layers of undercoat and filler applied.
At this stage I realised that the plans I had were not 'as built' and that the portholes were not in the same position port and starboard. A bit more filler and drilling new holes but I really should pay more attention to the reference photos.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey May 16, 2016, 12:50:36
Skinned the funnel carcass with styrene and added the exhaust vents. I couldn't get the 0.5mm styrene to bend smoothly to form the curved front section of the funnel so it is made up of 3 layers of 0.2mm styrene. Worked out OK and is very solid.
I had expected the guttering on the wheelhouse roof to be quite difficult but it went on really easily. Glad I decided to add it, could easily have left it off. The wonders of CA glue! Couldn't do without it.
Still a way to go but it's starting to look the part now and there seem to be fewer blemishes after each session.
One more round of filler/sanding/undercoat and it'll be about ready for a topcoat. Fingers crossed.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: VANYA May 22, 2016, 03:58:50
Steve. I had a look for those photos but no luck just yet. We have lots of them and they would be of great help.

: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey May 29, 2016, 16:25:27
Thanks Hayden, especially after any photos of the anchor windlass. No idea what it looks like as every photo I have shows it covered with a tarpaulin. I'll have to decide whether to make a best guess or get some more research. The real boat now works out of Australia and the owners where quite helpful at the drawing up stage but I don't really want to hassle them anymore so might be a 'close enough' scenario.
Slow progress on the build at the moment. Making lots of fiddly little bits that seem to take ages. Spoke too soon about the easy installation of the guttering. Took most of a weekend to install the window frames. Made a real hash of it and had to start again several times. Took the best part of another day to make the 2 engine room vents. Got a box full of completed hatches, vents and doors.
I've assembled the funnel/mast and added the very small life raft rack and radar/running light brackets. Just about ready for last undercoat and topcoats.
The roof is not glued on yet as that needs to be painted the same blue as the deck. Too hard to mask up when attached to the funnel and wheelhouse. Also, the downpipes from the guttering won't go on until later.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey May 29, 2016, 16:27:13
Still need to make the lights, searchlights, radar and safety equipment, and trying to dodge making a decision about fitting out the interior.
Only major bits left to make are the anchor windlass and railings.

: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey August 04, 2016, 16:00:25
I haven't updated the build recently as I pretty much lost steam on it. Started with a hiss and a roar and then work and other thing got in the way.
I have been slowly and intermittently making little bits and pieces to go on the boat – and there always seems to be more on the list however I'm back on the job now. First thing I managed to do was drop the bridge and break off the top of the mast – Doh! It had gone together really easily first time round but the repairs took ages and needed lots of tweaking.
I hadn't had any reference of the anchor windlass but Phil (mermod) sent me a couple of images of another (Tasmanian) vessel in this class and using a bit of licence I came up with a reasonable looking windlass based on Phil's version.
: Re: 1970s Diesel Harbour Tug 'RANGI'

...and painted.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey August 05, 2016, 17:27:44
Also made a start on the railings.
I made up a simple jig/template for the flying bridge railings – much easier getting the 3 rails to bend into the same radius this way.
The other railings took a bit longer than anticipated but I don't mind the whole soldering/filing process so it was a quite relaxing couple of evenings.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey August 05, 2016, 17:40:11
I've slowly been adding to the box of bits to go onto the boat. There is a completed boat in there somewhere. Only the lights (12), flying bridge console, life buoy brackets and speakers left to make – yahoo!
From today there should be more going out than coming in.
Started placing the various components in place. First the deck equipment, then the fenders, then starting on the superstructure. As usual there is a order that things need to be done and as usual I find that I either haven't made something or need to remake/repaint something and the whole process stops for awhile.
Everything is waiting on the glazing at the moment, which is waiting on a paint touch-up.
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey August 05, 2016, 18:05:16
The fenders went on much easier than I had imagined.
The fender rubber is a strip of foam rubber that I have had laying around for ages. That was stuck on with contact rubber adhesive. You only get one shot with that stuff so I was very careful when positioning the rubber. Worked out OK.
The fender straps and turnbuckle straps are the thinnest brass rod I could find.
The hull and deck are now just about finished. Added the fire-hose piping, engine room escape hatch, towing bow and capstan, and the anchor windlass and platform in the bow. The deck and its equipment are all the same colour so it all tends to blend in together, same with the turnbuckles on the fenders – hard to see any detail – I guess that works in my favour
Only things on the hull left to do are the tyres and I can't put them in place until the boat's name and hull markings go on and that is always the last thing I do in a build. Hopefully that won't be too far away.

Slowly but surely making progress.
Needed to touch up the paint in a few areas and was then able to start attaching items from the box of bits. Also repaired the damage to the mast – I'm taking a bit more care with it now – don't want to do that again.
The engine room vents are waiting for their covers and the work floodlights will go onto the supports next to the vents. Just the deck lights, railings and a few more deck vents to add.

Thanks Romanov. How is the Centaur going?
I often visit the Polish model sites and there are some great models there. There are plenty of great Polish tugs I would like to make: Tygrys, Bogan, etc. One day, maybe?
Back to the build.
The tow hook came together surprisingly easily. Not functional so it's made from styrene.
Finished the nav lights yesterday and the binnacle this morning so no more pieces to make. The end is in sight. Yahoo!
: Re: 1970s Diesel Harbour Tug 'RANGI'
: sea monkey August 16, 2016, 13:46:36
Had a real between jobs so was able to crank this along over the past few days.
These next photos have shown up a few areas that need to be touched up but well into the home straight now.
I've been attaching all of the pieces made earlier and it's coming together at last. These photos show the superstructure all completed apart from the searchlight and lifebuoys and widow wipers.
The hull still needs its tyres chained on.
And a display stand – forgot all about that!?
Should all be finished in a few days if work doesn't get in the way.

When the real boats were in this colour scheme the Otago Harbour Board (OHB) had become Port Otago so the OHB logo was no longer used, however it is such a good logo and was originally on the boats in brass so I've re-instated it.
Similar license with the fire hose – the real boats had black rubber hoses, I've used the woven type, which is strip styrene – and they do stretch the length of the deck.

Same licence with the work lights – the real boat had wimpy little fluoros so I've upgraded them to beefy halogens.

Hi Steve.

Its great what you can do with a flat piece of paper we sent you!

What a brilliant model.

I like the version with the yellow funnel mostly but your version is not so familiar. It appears "they" have had many guises over the years.

Great stuff.

Any hint of what is next?  "Ohau" pilot from Timaru will be history next year, to be replaced. Also connected to Dunedin as Robert Davis was the designer.

Thanks Romanov. How is the Centaur going?
I often visit the Polish model sites and there are some great models there. There are plenty of great Polish tugs I would like to make: Tygrys, Bogan, etc. One day, maybe?


Hello
The plans are no problem to get. Bogdan or other
give me a pm on his email is something spreading :)


Centaur II have already made hull laminate and soon I will have him occupied.

Thanks Romanov, I look forward to a build log of the Centaur.
Thanks Hayden. I've got the Ohau hull drawn up for you and ready to have laser cut. They can't cut 9mm so may have to be 2 layers of 4.5 at 1m LOA. Probably stronger that way anyway. I'll send a PDF in a day or so.
Next project also has a link with Dunedin but only built there. I should be able to post some progress shots in the next week or so.
And thanks to everyone who has been following.
Finally got round to adding the last little bits and pieces – aerials, lifebuoys and put on tyre fenders. A few areas needed a little touch up with paint, and lastly... the names and hull markings were applied.
I'd forgotten to make a display stand so that took a few hours extra but now it is all finished and can start gathering dust. Yahoo!!

Steve.
A fine model and a very fitting tribute you have created to the Otago Harbour Board that took it upon themselves to build their own tugs. Both vessels have had a very commendable life working Otago Harbour and they continue to perform in thier new location in Australia.

Well done.

I am thinking it might be the W.H Parr next?

Was in Wellington and got some shots of the two Damens returning to thier berth. They certainly both had a busy weekend in Wellington.

Thanks Des and Romanov.
Thanks Hayden. Good guess, WH Parr is on my wishlist. I think that one of the members here (Speedweeder) is building one. I got onboard last christmas and got a heap of photos but haven't been able to track down any hull lines or even a GA. The port never had any to begin with. It's basically similar to the Rangi hull so I could bluff it but that may be for another day as I've got something else in mind for the next one up. It also has a link with Dunedin but only built there.

Must be the Rupe then.

She was a Sims build I think.

Was the Rangi a 48th scale build?

You have built one of the ex Wellington Voith tugs too havn't you?

Steve.

I could send up the Te Maru hull for you to do you magic on. Its too small for r/c really but the hull is fine for your type of finish. You can add it to the list😳

Seems like the Herematanga days vould be numbered to in Nelson.

You will have a little maratime museum at this rate.

Hayden,
The Hikurangi from Gisborne. Built by Miller & Tonnage and now retired back there. It's tiny.
I do plan on a Te Maru sometime. Not many of those Japanese tugs left here any more.
What size is your hull? 1/50?
All of my past builds have been 1/50 so I'll stick with it.
Yes, I also have a Kupe and a Te Matua (formerly from Tauranga, now in Bluff).
The Kupe is a great looking boat, my son got to drive it when he was 5, at a port open day.
The Te Matua is pretty unique. Some might say strange looking/ugly.
They were my first attempts at modelling 20 years ago and could probably do with a rebuild. Kupe is RC but with twin props rather than Voith drives, Te Matua is a straight runner (first attempt at a motored boat).

Steve,

Where is the Hikurangi at present?

I am going to Dunedin this Saturday.
