How to build a boat Catamaran you can live aboard part 1

This is the first of a series of tutorials about a catamaran I built back in the 90s. Building a boat, something big enough to live on and sail off over the horizon is a dream I had for years. My original idea was to build a monohull, in fact I bought plans for a little 21 footer that I was going to weld up and sail around the world in. The plan got postponed for a number of years.

And in that time I come across a couple of books that changed my ideas. It was back in the early 90’s First book was the Gougeon Brothers on boat building, all about building with epoxy and wood. And the other book was the cruising multihull by Chris White. The two of them together made sense Building a multihull, that didn’t rely on tonnes of lead to keep itself upright and building with wood, epoxy and fibreglass, all made sense to me.

I found plans I liked from a local multihull designer, Tony Grainger. I then started preparing the place to build it, in the bush on my parents property out the back of Noosa Heads. Queensland, Australia. The original shed was only big enough to build the 21ft boat that I originally planned to build. So I lengthened it with the idea of building the boat in 3 sections.

2 hulls separately and then the centre section. Which I ended up doing. Building of the hull starts with a strong back. It’s a ladder like construction that I concreted into the ground. I cut out temporary frames in chipboard. to make the cross sectional shapes of the hull. Using full size contours on mylar sheet that I laid down on the wood and traced out with a dressmakers wheel.

Each temporary frame is set up on the strong back. and lined up. It’s worth spending a little extra time to get everything spot on at this stage Getting it all lined up perfect. and the contours cut out perfect. made for an absolutely fair hull. It saves you a lot of time down the track. The construction was strip plank western red cedar.

Basically a wood cored fibreglass boat. My reasons for building it this way were that its a simple system for a one off boat You don’t need to build a mould before you can make it. produces a very fair hull. It’s strong, its light. The cedar strips were 14mm thick and for the majority of the boat 90mm wide.

What I’d bought, machined ah, were not long enough to make up the length of the hull so they have to be scarfed together to give you the full length of the hull. I set up a jig with my brothers radial saw, to saw them all give them a feather edge for scarfing. and then set up a jig table to scarf them all together. Once they were dried then I could start screwing them on to the temporary frames. Edge gluing them as I went.

Building Tiki 26 in 180 Days

For years I had been longing for my own boat while sitting at the sea or in the docks. I had bougth literature and magazines with a scent of see. I went diving, fishing and sometimes I drove a boat. I even bought two plans but I never had the guts to start. One day in a magazine called YU NAVTIKA I read several articles about catamarans. I was the most inspired by Milos Delac’s article describing a DYY 8 meter. It was love at first sight.

I wrote to the constructor and he sent me a brochure and after that i could not decide to build it for another long 15 years. To choose a boat is no picnic. There are many questions and the choice depends on several things the aim and the area of sailing included. A boat should be easy to carry around, it should not think too deep, there should be a lot of space on the deck, it has to be fast and of course it has to be low cost and easy to maintain.

The other day I was sitting at the end of the dock in the town of Izola watching boats sailing by thinking how it is all about three primal wishes: luxury, speed and low price. I was thinking how to join all of them and i was comparing boats along themselves. A luxury and fast boat cost a lot of money. A luxurious and cheap one is usually an old fart that gets you nowhere and there are high costs included and and unforeseen. Well, a quick, luxurious and chip boat. with a large deck. that does not.

Think too deep while sailing. even the transport needs to be easy. That could only be a catamaran! In the summer of 2003 it has all started. I sent 385 GBP to the constructor in Great Britain. After a week I got a huge envelope with construction plans in it. The next day I have already caught myself buying wood. The most i was wondering how can an amateur that knows nothing about.

Building boats can built a DIY (doityourself) catamaran. Probably it was because of this question that the majority never thinks of DIY. Well, it was no difficult, I just started and somehow it went. The constructor adapted plans to beeasyto read for those that have no clue what doit yourself means in the first place. The doityourself construction plan is actually a comic book including all of the instructions on how to use tools and materials.

It is meant as a construction of playwood, wood and epoxy. So the boat is easy, flexible and strong. I got all the material without a problem in Slovenia. I got oak wood and ocume playwood in a Slovenijales store in Setvid near Ljubljana that is usually imported by the Javor company from the town of Pivka. Even this company has its store in Ljubljana, however they want you to pay immediately. In Slovenijales they gave me wood in advance and a had it transported.

I bought epoxy in Mitol in the town of Sezana all other extras for mixing fillets and fabrics I got in the Mirnik company in Ljubljana and some of it in Trieste. We started to build the catamaran in the beginning of July on our home backyard. in three weeks the rough construction of the first boat was peaking aut of our home garage. It was finished in a month and a half, afterwards we started to build.
