Oloff and Muir de Wet, two South African brothers, accomplished themselves welding, CAD programmes, keel casting and so abundant added en avenue to architecture their dream canoeing yacht.

One of the highlights is breadth Palley warns adjoin actuality “overly committed to comfort”. He urges us to
“break the arrangement of anticipation that says added comfortmeans a bigger life. The acceptable lifehas ****-all to do with comfort.The acceptable activity has to do with addition apperception and body…”
Ongemak, the name of our boat, is the Afrikaans babble for discomfort. It was additionally the name of our grandfather’s farm, and from the moment that Muir and I came up with this name, it stuck, it grew, and sometimes became affiliated to a active force abaft the project. It was a name that at already reflected our roots in the platteland (remote country) far from the sea, as able-bodied as a faculty of chance and a alertness to cede abundance and abundance zones for new, alien horizons.
Muir and I had our aboriginal austere aftertaste of sailing (albeit not of alkali water) about 10 years ago when, calm with our accompany Tinashe, Elisma and Adolf, we acquired a Miura, a 31ft fin-keeled sailing yacht advised by Oswald Berkemeyer, on the Vaal Dam. An commodity like this is no abode for allotment blame, but it was mostly Hennie Olivier’s fault.
Having alternate to South Africa afterwards a year-long transcontinental trip, Muir and I were cogent Hennie the adventure of how we had spent our aftermost black on the admirable Dakar Yacht Club balustrade adequate sundowners. Staring out over the boats, we’d already started absent of new frontiers. So Hennie anon got up to aback his Sailing annual from the car, and calm we started activity through the classifieds. He afterwards collection from Bloemfontein to admonish us aback we bought the Miura.
Having a Miura on the Vaal accepted to be absolute for our alteration from acreage beastly to amphibian. The Vaal can occasionally be nasty, but it is mostly friendly, and a Miura is consistently a absolute affectionate boat.
But we additionally abstruse that owning a baiter is about a lot added than sailing. It is a way of life, and actuality allotment of a association of generally aberrant individuals. It is interacting with attributes in the best aboveboard way, and (if we are honest) generally has a lot added to do with the absolute befitting and advancement of a baiter than sailing it. This played a above allotment in what followed.
Human attributes agency that we consistently appetite added and, sadly, sailing does not cure us of this malady.
Soon I started cerebration of improvements to the baiter – baby ones at aboriginal and afresh added beyond ones. It didn’t admonition that I was active with a PhD in geometry, because generally during my years of abstraction I begin that aback assignment called, some added activity able amusement started calling like a siren in an alike louder voice. So boring an abstraction started brewing…
My mother generally says that Muir and I are twins built-in two years apart, and it is accurate that we allotment a accord that is sometimes uncanny. So it came as no abruptness that, aback we apparent we’d both abashed on to a new folio in our lives, it was in actuality the aforementioned folio (he was now alive in aerospace anesthetic in the Middle East and I was a academician in Pretoria).
This is what our new folio said:

it makes no faculty to advertise the best eight hours of every day. Activity is abbreviate and the apple is big. Let’s move to Cape Town and body a yacht.
So in our backward 30s we both abdicate our jobs. We said goodbye to the office, assured that we would anon adept the mystical abilities of adjustment and the wielding of ability tools. Success was a given, because aback he was seven and I was nine, we congenital a absolutely nice timberline house. We evenhad the dog up there.
This is what we wanted:
We capital an abandoned carapace so we could architecture our own autogenous blueprint and systems, so we began attractive for a banal bark and deck. But somehow, alike admitting we looked at absolutely a few, we were never happy. It eventually dawned on us that what we capital was article abundant too specific. We realised that we’d accept to body our own baiter absolutely from scratch.
There is a lot of admonition accessible on altered bark abstracts – steel, wood, glassfibre, ferrocement – and on the pros and cons of each. Our baiter was to be acclimated accurately for canoeing and we acclimatized on aluminium as the actual of best for the afterward reasons:
It was Peter Smith, and afterwards this aboriginal accidental appointment at the club he and Marlyse visited us at home on our activity on several occasions with lots of admired advice. He is not one to enlarge or exaggerate, but aback asked about abstracts his acknowledgment was simple: no actual is perfect, but if he had to get addition boat, if would be aluminium.
Peter should apperceive – he has sailed to and explored Antarctica in his own baiter added than once.
As Peter said, no actual is perfect. The capital disadvantage of aluminium is the achievability of active corrosion. This can action aback addition metal, like stainless steel, is affiliated to the hull, abnormally in a wet environment.

The way to anticipate this is through a artificial gasket, appropriate adhesive or, alike added accepted these days, by application a non-metallic alternative, for instance a artificial seacock rather than a stainless animate one.
Galvanic bane can additionally action if there are devious currents abounding through a marina, abnormally if the underwater paintwork is not in acceptable nick. To anticipate this, aluminium boats backpack sacrificial anodes on the hull. There should be abundant of these and they should be arrested and replaced as bald every few years. This is not a botheration while canoeing and anchoring abroad from bartering power.
I ability acknowledgment that I accept generally heard the adventure of addition who alone a metal bread in their aluminium boat, and afresh apparent it a abbreviate while later, aloof in time, afore it has breakable beeline through the hull.
I accept it’s absolute nonsense, or at atomic one of those burghal belief that has become added and added absurd as it has been anecdotal over the years.
To be sure, we did the afterward experiment: six bottle jars, anniversary with a abyssal brand aluminium disc at the bottom, were filled, three with alkali baptize and three with beginning water. We larboard the aluminium bald – as far as I apperceive no one goes to the agitation of painting the abdomen of aluminium hulls. Into these we put samples of appropriately stainless steel, advance and a array of coins. Afterwards six months we advised all the samples, and alone breadth the advance sample lay in alkali baptize on the aluminium disc was there the aboriginal adumbration of pitting, beneath than 0.2mm in abyss and diameter.
Herein lies an important lesson, namely that it’s generally easier to analysis the authority of a account than to go on buzz or to get abashed by adverse theories begin on the internet.So don’t authority aback and be shy – analysis it, breach it, bake it or benumb it – it’s abundant fun!
Lastly, we should acknowledgment article about the bulk of aluminium compared with added materials. The aluminium plates for our baiter bulk the agnate of about £4,460, but to this has to be added the bulk of lots of consumables, as able-bodied as assorted $.25 of aluminium profile, so the absolute bulk of the bark and accouter was about bifold this amount, almost £8,900.
It may assume appetizing to body a baiter out of animate or wood, with the bulk of a bark and accouter actuality beneath than two thirds of this price. But it is important to realise that, compared with the bulk of the accomplished activity (around £41,600), this extenuative is beneath than 10%. To my apperception it makes no faculty to adaptation on the bark material, for this would access the appearance and the resale amount of the baiter for years to come. If money is to be saved, it can be done by accepting a simpler interior, centralized systems, accouterment or engine. These can consistently be upgraded later.
One of the best advantageous aspects of creating your own baiter is acquirements abilities you ability not accept acquired in any added way. Neither of us had anytime anchored before, so one of the aboriginal abilities we had to apprentice was MIG (Metal Inert Gas) welding. For this we contacted the South African Institute of Adjustment in Johannesburg and organised to go on a week’s course.
The advisers there were decidedly adjustable in realising that, clashing best of their students, we were not gluttonous any anatomy of certification, but rather a ample addition to altered aspects of adjustment from which we would be able to advance through practising at home.
At the end of the anniversary we were annoyed to the bone, but we were accustomed a acceptable nudge in the appropriate direction, as able-bodied as lots of admonition on what would and would not assignment for our aggressive project.

Back in Cape Town we bought a bargain MIG welder (which alone pushes the adjustment wire from the machine’s side) and had the cable beneath (for beneath friction) instead of affairs a added big-ticket push-pull machine. This formed absolute able-bodied and the wire hardly anytime got awash – apparently because the wire acclimated for adjustment marine-grade aluminium is absolutely stiff.
Then the fun started. We had lots of offcuts already we started acid the bark plates, and it was on these we practised. We additionally watched lots of YouTube videos and afresh we practised some more.
We cut the anchored metal up into strips and bankrupt it in the vice. If it bankrupt on the bond it was bad – if it bankrupt on the calefaction afflicted breadth abutting to the bond we were happy. The bureaucracy of welds seems to be like this: a bad bond looks acceptable but breach easily; an boilerplate bond looks bad but is difficult to break; a acceptable bond looks acceptable and is difficult to break. I anticipate I can cautiously say that our baiter consists of according amounts of the aftermost two types!
Another accomplishment was to apprentice how to use ability tools. The admiration of alive with aluminium is that accepted woodworking accoutrement are altogether sufficient: a annular saw (fitted with a brand for acid aluminium, accessible from any accouterments shop) goes through a accent of aluminium bowl in beneath than two minutes. An bend grinder or pencil grinder adapted with a carbide angled brand is absolute for removing the algid alpha of a adjustment run, but beware that an electric planer can abort your activity – and you if you’re not careful.
Just bethink not to use annoying discs or sandpaper breadth you appetite to bond afresh afterwards – these will alloy the breadth and advance to blowzy or attenuated welds. And don’t balloon to abrasion all that assurance gear.
There are those who accept that if you ambition for article absolutely hard, afresh you can allure it through some abstruse force. I’m not one of those people, but that’s added or beneath what happened anyway. One lunchtime at work, while gazing through our Sailing magazine, I begin a analytical advertisement: “Accommodation to let. Large attic on additional attic of abode in Milnerton, calm with garden amplitude acceptable for architecture a yacht.”
This was still a year afore we planned to move to Cape Town, but, as luck would accept it, my best acquaintance Paul Schutte was in Cape Town while finishing his own baiter project. Paul happened to be attractive for adaptation and he admired the abode so abundant that he agreed to hire it for himself in the interim.
The buyer of the abode originally capital to body his own yacht too, so he’d larboard amplitude abutting to the abode for his architecture site. This is good, because, as with abounding things in life, you should accept an avenue strategy. It ability be accessible to body a baiter in an amid space, but it’s absolute difficult to get it out again!
With board poles and beams covered with artificial tarpaulin and adumbration cloth, we congenital a 12m continued bivouac abutting to the abode (MIG adjustment requires a wind chargeless environment). It was a admirable amplitude so we threw a massive affair for all our accompany – and if you acquaint lots of bodies that you’re activity to body a yacht in this big tent, afresh you accept to do it!
