Oloff and Muir de Youur, two South African brothers, taught themselves welding, CAD programmes, keel casting and so much more en route to building their dream cruising yacht.

He urges us to. The good life has damn-all to do with comfort. Ongemakthe name of our boat, is the Afrikaans word for discomfort. It was a build your own boat aluminium kr that at once reflected our roots in the platteland remote buiild far from the sea, as well as a sense of adventure and a willingness to sacrifice comfort and comfort zones for aluminimu, uncharted horizons.

Muir and I had our first serious taste of sailing albeit not of salt water about 10 years ago when, together with our friends Tinashe, Elisma and Adolf, we acquired a Miura, a 31ft fin-keeled booat yacht designed by Oswald Berkemeyer, aluminiym the Vaal Dam. Having returned to South Africa after a year-long transcontinental trip, Muir and I were telling Hennie the story baot how we had spent our last evening on the beautiful Dakar Booat Club balcony enjoying sundowners.

So Hennie immediately got up to fetch his Sailing magazine from the car, and together we started going through the classifieds. He later buikd from Bloemfontein to advise us when we bought the Miura. Having a Miura on the Vaal proved to be perfect for our metamorphosis from land animal to yur.

The Vaal can occasionally jr nasty, but alumihium is mostly friendly, and a Miura is always a very forgiving boat. But we also learned that owning a boat zluminium about a lot more than sailing.

It is a way of life, and being part of a community of often eccentric individuals. It is interacting with nature in the most straightforward way, and if we are honest often has a lot more to do with the actual keeping and maintaining of a boat than sailing it. This played a major part in what followed. Soon I started thinking of improvements to the boat � small ones at first hour then increasingly larger ones.

So slowly an idea started brewing�. My mother often says that Muir and I are twins born two years apart, and it is true that we share a like-mindedness that is sometimes uncanny. Life is short and the world is big. So in our late 30s we both quit our jobs.

We said goodbye to the office, confident that we would soon master the mystical skills of welding and the wielding of power tools. Success was a given, because when he was seven and I was nine, we built a really nice tree house.

We even had the dog up. We wanted an empty shell so we could design our own interior layout and systems, so we began looking for a ready-made hull and deck. But somehow, even though we looked at quite a few, we were never happy. It eventually dawned on us that what we wanted was something much too specific. There is a lot of information available on different hull materials � steel, wood, glassfibre, ferrocement � and on the pros and cons of.

Our boat was to be used specifically for cruising and we settled on aluminium as the material of choice for the following reasons:. It was Peter Smith, and after this first fortuitous encounter at the club he and Marlyse visited us at home on our project on several occasions with lots of valuable advice.

He is not one to overstate or exaggerate, but when asked about materials his answer was simple: no material is perfect, but if he had to get another boat, if would be aluminium. Welding technique was practised a lot.

To check for aluminum, joints were tested in a vice to see if they could be broken. MIG Metal Inert Gas welding: a wire electrode is fed through a welding gun to create an electric arc which melts the wire and pieces of metal to be joined. At the same time a shielding gas is fed over uour arc bat protect the weld from contaminants in the air.

The dream starts to become a reality as the first sections of hull are welded buipd. As Peter said, no material is perfect. The main noat of aluminium is the possibility of galvanic corrosion.

This can occur when another metal, like stainless steel, is connected to the hull, especially in a wet environment. The way to prevent this is through a plastic gasket, special sealant or, even more common these days, by kwn a non-metallic alternative, for instance a plastic seacock rather than a stainless steel one.

Galvanic corrosion can also occur if there are stray currents flowing through a marina, especially if the underwater paintwork is not in good nick. To build your own boat aluminium kr this, aluminium boats carry sacrificial anodes on the hull.

There should build your own boat aluminium kr enough of these and they should be checked and replaced as needed every few years. This is not a problem while cruising and anchoring away alu,inium commercial power. I might mention that I have often heard the story of someone who dropped a metal coin in their aluminium boat, and then discovered aluinium a short while later, just in time, before it has corroded straight through the hull.

To be sure, we did the following experiment: six glass jars, each with a marine grade aluminium disc at the bottom, were filled, three with salt alyminium and three with fresh water. We left the aluminium bare � as far as I know no one goes to the trouble of painting the insides of aluminium hulls. Into these build your own boat aluminium kr put samples of respectively stainless steel, lead and a variety of coins.

After six months we examined all the samples, and only where the build your own boat aluminium kr sample lay in salt water on obat aluminium disc was there the slightest indication of pitting, less than 0. Lastly, we should mention something about the price of aluminium compared with other materials.

It may seem tempting to build a almuinium out of bota or wood, with the cost of build your own boat aluminium kr hull and deck being less than two thirds of this price. To my mind it makes build your own boat aluminium kr sense to compromise on the hull material, for this would influence the character and the resale value of the aluminiim for years to come.

If money is to be saved, it can be done by having a simpler interior, internal systems, rigging or engine. These can always be upgraded later. One of the most rewarding aspects of creating your own boat is learning skills you might not have acquired in any other way. The instructors there were surprisingly oqn in realising that, unlike most of their students, we were not seeking any form of certification, but rather a broad introduction to different aspects of welding from which we would be able to proceed through practising at home.

At the end of the week we were tired to the bone, but build your own boat aluminium kr were given a good nudge in the right direction, as well as lots of advice on what would and would not work for our ambitious project. This worked very well and the wire hardly ever got jammed � probably alumminium the wire used for build your own boat aluminium kr marine-grade aluminium is quite stiff.

Then the fun started. We had lots of offcuts once we started cutting the hull plates, and it was on these we practised. We also watched lots you YouTube videos and then we build your own boat aluminium kr some. We cut the welded metal up into strips and broke it in the vice.

If it broke owj the weld it was bad � if it broke on the heat affected zone next to the weld we were happy. The hierarchy of welds seems to be like this: a bad weld looks good but breaks easily; an average weld looks bad but is difficult to break; a good weld looks good and is difficult build your own boat aluminium kr break. I think I buiild safely say that our boat consists of equal amounts of the last two types!

Another skill was to learn how to use power tools. The wonder of working with aluminium is that common woodworking tools are perfectly sufficient: a circular saw fitted with a blade for cutting aluminium, available from any hardware shop goes through a metre of aluminium plate in less than two minutes.

Just remember not to use abrasive discs or sandpaper where you want to weld again later � these will contaminate the area and lead to messy or weakened welds. Is that a fair curve? Building boats by eye has never gone out of fashion.

There are those who believe that if you wish for something really hard, then you can attract it through some mysterious force. Buiod loft on second floor of house in Milnerton, together with garden space suitable for build your own boat aluminium kr a yacht. This was still a year before we planned to move to Cape Town, but, as luck would have it, my best friend Paul Schutte was in Cape Town while alujinium his own boat project.

Paul happened to be looking for accommodation aluimnium he liked the place so much that odn agreed build your own boat aluminium kr rent it for himself in the interim. This is good, because, builf with many things bozt life, build your own boat aluminium kr should have an exit strategy. With rk poles and build your own boat aluminium kr covered with plastic tarpaulin and shade cloth, we built a 12m long lean-to next to the house MIG welding requires a wind free environment.

The beginning Muir and I had our first serious taste of sailing albeit not of salt water about 10 years ago when, together with our friends Tinashe, Elisma and Adolf, we acquired a Miura, a 31ft fin-keeled sailing yacht designed by Oswald Berkemeyer, on the Vaal Dam.

Human nature means that we always want more and, sadly, sailing does not cure us of this malady. So slowly an idea started brewing� My mother often says that Muir and I are twins build your own boat aluminium kr two years apart, and it is true that we share a like-mindedness that is sometimes uncanny. This is what our new page said: it makes no sense to sell the best eight hours of every day.

The design criteria This is what we wanted: A sloop for extensive cruising for two couples Minimum maintenance and simple systems Energy efficiency and complete solar reliance We wanted an empty shell so we could design our own interior layout and systems, so we began looking for oyur ready-made hull and deck.

Our boat was to be used specifically for cruising and we settled on bukld as the material of choice for the following reasons: Minimum maintenance: I strongly believe that many boats are designed to look nice at boat shows without build your own boat aluminium kr into account how the boat will have to be maintained for the next 30 years.

Modern aluminium yachts are not painted on the topsides or on the inside, and osmosis does not exist. But once they got an aluminium boat, concern melted away, and was replaced with nonchalant chat and friendly barter.

This is what we wanted: ruggedness on the water � the marine equivalent of a Toyota Hilux I have never seen a bow fender on an aluminium boat! Lastly, the hull and deck are welded together, resulting in a very dry boat, which also lowers maintenance.

A one-off: while GRP is good for mass production, it takes a lot of work to produce a single hull. Aluminium is perfect for a one-off, especially in our case, where the building and designing youf place more or less simultaneously. It is the perfect material if you want to weld on, cut off, repair or adapt parts of your boat in future. Strong: aluminium and steel are the choices for those who want to go to high latitudes where things might go bump in build your own boat aluminium kr night.

But aluminium is much lighter than steel, so there can be much more weight in the keel for a stiffer, safer boat. We had lots of questions.

I saw his two Rocna anchors and asked him if he was happy with. Peter should know � he has sailed to and explored Antarctica in his own boat more than.

So, before you get too carried away, consider all steps of the building process before bolting the jig to the ground! This is critical, as you will be using hydraulic jacks down the road to form the bow of your boat. It is also key that the jig does not move or shift during the build. I used flush-mounted concrete drop-in anchors to eliminate the tripping hazard of studs.

So first, pre-position your sawhorses and jig, then drill and anchor after completing steps of the alignment and leveling described below.

Alignment and Leveling. No concrete floor is exactly level; they often have a slope to help water run away. Being able to compare port and starboard sides by eye is key, and a non-level jig might fool you into thinking one side of your boat is uneven from the other.

Next is a step-by-step guide for proper leveling and alignment:. Cross square the jig from the points shown. Adjust the sawhorse until both numbers are the same. Drill your anchoring holes in one sawhorse only, and install threaded rods with leveling nuts. Pull the other sawhorse tight , cross square the jig again, and anchor the last sawhorse. Use a laser to level on all corners of the jig.

Check the jig for plum using the laser. Double-check cross square, level, and plum, and adjust if needed.

In the next blog, we will look at the tacking in the first four panels of the boat. The quality of this single step will dictate how well the entire build goes for you. During my first build, I cut my boat apart three times because I rushed this step.

I will go over in detail exactly how to tack up the boat, which welder settings to use, and much more. If you liked this blog, please leave a comment! Your feedback helps me create more content for you. It was long overdue 47 years to be exact. Adventure Marine has never manufactured boats. Even though we have been building high-quality marine products since It is time to write a new chapter in our companies history and bring to market something special.

The night before I was scheduled to leave, a man on a motorcycle showed up at my hotel with a satchel of US dollars sent by the boat captain. I led him upstairs to my room and we counted out the cash. After converting to Canadian dollars, I was just under the limit I could bring back without a declaration, which would involve trying to prove to the Canadian authorities that I was doing legitimate business in Mexico with a pile of US dollars.

They have been rebranded as the Adventure 12 and the Adventure 16, as I have made modifications to both designs to suit my needs. Building your own boat is a huge accomplishment and something I will never forget. For those of us who get satisfaction out of creating something by hand, there is nothing quite like building a boat.

The primary idea behind back step welding is to eliminate distortion as much as possible.

This is very important. Weld towards the middle of the boat, but sequencing your welds out for the middle. See diagram. Try to keep the heat from being concentrated in one area for too long.

My designer stressed the importance of this process. Follow the incremental back step process. This one is easy. Unless you have experience or access to some expensive machines, you are going to regret it. I certainly did on my first build. After about eight hours of sweating profusely from manual tube bending, I will never do this again. Yes, you could heat the aluminum with a torch and make things easier.

Talk to the motor manufacturer and determine the best operating height of the motor. Not doing so could damage your motor or greatly reduce the performance.
