Sailing around the world solo on 22 foot beach cat was not enough for Yvan Bourgnon, he needed to sail through mythical NW passage as well! 4 degree water, icebergs, polar bears – all that shit that you would like to avoid in normal sailing…
After couple of days planing-sanding-planing-sanding-swearing-sanding-planing-sweating-sanding-swearing-planing-sanding i finally managed to produce snugly fitting top and heel for the mast:
and yes, this will be my victory dance:
Okay, now there are some little jobs carried out.
Dolphin striker has a glass fiber reinforcement to prevent splitting (there will be whipping as well later on and yes the picture looks a bit masculine)
Compensation plates for forward crossbeam… there were some mysterious gaps between beam blocks and beam.
Top and heel portions of the mast were made of 4 pieces of planks glued together for extending a 6m alu tube – just 4 days of planing and sanding – truly handcrafted stuff :p (will not to it again next 20 years, but people with insomnia, I will recommend it — you will have good night sleep, at least when you have cleansed your nostrils from hefty sanding dust deposits)
A pretty grand moment 🙂
Its already August – soon enough nasty long, damp & dark winter will knock on the door… Still I have some glimpse of hope, as I finished port hull paint job — I only need to fit windows, main hatch hinges and rudders.
Port hull with fresh paintjob
Just look at these neat curves 🙂
Just some few odd jobs left… here’s centre beam under pressure waiting epoxy to reach its final stage (slow hardener for gluing; 50% fast, 50% slow for fillets)
Starboard hull with its new paint (same as port hull — Tikkurila Temadur 20)
Playing with the paint & sniffing the fumes….
… two part epoxy based Tikkurila Temacoat RM40 serves as primer for the hull, I will let it to set for a few days, then there will be applied two part polyurethane Tikkurila Temadur 20 fas a topcoat. Interiors are already coated with several layers of Temacoat, which is a bit easier to apply in constrict spaces, as it do not go off too quickly after mixing and its a bit more viscose as well, a true virtue considering the situation where painter has to squeeze himself into the rear section of cabin, size of a smaller nightstand, armed with pot of potent smelling paint, flashlight, small brush and watering eyes.
… a fancy DIY knob for main hatch locking system, made of 2 layers 6mm plywood (will see how it works…)
… and little bit of woodwork as well — a base for jib block, made from 2 pieces of oak, clued and screwed onto the hull.
I decided to abandon jib traveler and went for barber haulers.
Now I need one dry and warm day for painting the topsides and another for hull sides…

Port hull almost done, still lots to do…
… waiting in the list:
glass 2 cabin sides, glass tape main companionway & forward hatch coamings glue beam sockets/pads bolt & glue beam/shroud lashing pads
- produce forward and center beam
- produce mast top and step for aluminum tube
- make tillers & gaff
- lash rudders to hulls (port hull needs lashing holes as well)
- fabricate slatted deck
produce forward & main hatch for port hull
- install all the necessary small bits that will make run everything smoothly (supporting pads for deck, jib blocks and barber hauler, main hatch locking system, beam cleats etc)
- sand & paint everything (including starboard hull)
- install port hull windows
- raise mast & get out onto water
There are literally thousands and thousands erroneously well paid decision makers, business men, politicians, bureaucrats around the planet — in their fine designer suits and snake skin shoes, they are squatting acres wide conference halls, “discussing” how to protect forest (and therefore lives of millions who depend on the woodlands), producing more warm air than real outcome. We all know their excuses and got used to it, so we have grown a confidence in their neatly served alogisms : “taking direct action is too complicated and its not good to economics,” they say, “we can not conserve wildlife, will lose many jobs!” they lament. The elephant in the living room — that is it.
And then you look at this underprivileged, but touch guy who over the decades single-handedly planted whole 550ha forest to save an island… That makes you think…
Hi folks, it has been a while, since my last blog post, but nevertheless Tiki project hasn’t stayed idle. Day by day Itatae has gathered some flesh into bones.
Here is latest report…
Taking time to smooth out the wrinkles makes it easier later.
Well thats nice, isnt it…
Last drops of epoxy and last bits of glass joined with painstaking care 😛
Hefty overhang for stem (trimmed later with carpet knife before resin is fully set)
Finshed product with Microlight filler coat.
Back on heels.
She will look nice, doesn’t she…
With two pairs of helping hands it was rather pleasing act to glue on the forward deck.
Thanks a lot, mates!
Those freshly glued front deck stringers got nice and cozy overnight stay under this i-love-to-hassle-with-masking-tape tent
Bunks are ready for port hull. Now there will be some paint job (Tikkurila Temacoat RM40) and stringer job before gluing the decks on. Looking good, hopefully I could keep up the pace…
Epoxy cooking in winter conditions… coating bunk undersides.
There has been pretty few progress since port hull went 3D, but thanks to yesterday’s long hours in garage all the bunks and stringers are ready for next phase, which means a little bit of sanding and then painting underneath of bunks and watertight compartments as well, before gluing bunks in.
So… second hull got stitched up and yesterday I made some nice fillets for keel & bulkheads for 2 sections… I think its time to talk about little variations and changes I have made and plan to make into workflow, just to make whole process a little bit smoother and less time consuming.
- Preparing hullsides – this time after gluing and coating hullsides, I sanded all the surface of inner faces and treated bulkheads likewise, as it was for starboard hull a truly utter PITA to sand them in assembled hull; also I beveled underside corner of sheer stringer with a planer, leaving sheer stringer double locations untouched – comfortable and easy way.
- Nailing – as I have described previously I started using temporary screws or clamps to hold pieces in place during gluing, cause its pretty impossible to get those copper nail heads nicely flush with surface without using sledgehammer. But still occasionally I went for nails, but with variation I drilled ca millimeter deep holes with diameter of nail head for the nails to get nail heads flush with surface, otherwise its not easy later when sanding to maintain epoxy coating on top of the protruding nail heads.
- Stitching – I abandoned the copper wire, using cable ties exclusively. The main reason I used them in first place was my antipathy towards all sorts of single use throwaway plastic products – but then I realized, that environmental cost of messing up with epoxy in some point would be much greater than those few disposed plastic straps. Second consideration was that copper wire is re-adjustable, which it is basically, but only for one or two times, after which it parts. But one will learn quickly not to over tighten the cable tie. Copper wire is little bit easier to tighten, but one learns quickly to fasten the cable tie without putting whole body behind it with a risk to accidentally move pieces to be glued from their desired locations.
Copper wire ties tend to have another nasty habit, that is secretly to tear holes in your protective gloves, and when you have finished gluing, treated your hands with West System epoxy resin removing cream and started cleaning up the mess, then you will realize that there are long painstaking hours ahead cutting wire, filing off protruding leftover parts and fishing out those wires that have buried in their tiny sarcophages of hard rock cured epoxy because you didn’t wipe off excess of the glue properly.
- Bunk bearer – like for starboard hull I glued bunk bearers into bulkheads before inserting them into hull, but this time, after hull was stitched up I glued triangular shape stringers to bunk level line, so no need for hard core boat building yoga to produce fillets for bunk undersides.
- Cutting bunks – I didn’t saw much point for lofting a curved line for bunks, as the camber for the bunk edges is only a few mm for those couple dozens of cm.
- Painting bunks undersides before gluing them on – do not forget to do that, Agur, you old chap!
- Extra reinforcement & layout changes for bunk in companionway section – Wharram plans call fillets covered with glass tape for fixing the bunks, but I think it would not do harm to fully glass the bunk in companionway section – this is section of the bunk that will get most of the battering. Like Brad on his Beto I changed the lengths of fixed bunk plates in companionway section to make sitting in cabin a bit more comfortable. This has been done already for starboard hull and it worked great, so I will adapt this modification in port hull likewise.
Those modifications seem rather irrelevant, but again, when most of the (epoxy related) works are carried on by single person, then every little nuance start to play important role, especially those that help to reach results easier and faster.

A key for levelling the hull.
Port hull has started with tears, sweat and blood…

A friend lent me a helping hand, so applying the roll & tip technique was a piece of cake. It took only 1,5h hours to entirely coat the hullsides. After few hours we added second coat and in next morning Itatae received third one. Im thinking to add fourth layer as well and this time I plan to add some thinner as well, to get a bit smoother surface.
By the way – I switched from Tikkurila Temadur 20 (polyurethane) to Tikkurila Temacoat RM40 (epoxy based), which is much easier to apply as it does not give such potent fumes as the first one, also it has a bit longer pot life as well – which are much appreciated characteristics when you are amateur builder working in tight conditions. So, will see how this thing will work out in the end.
So, hull sides got finally glassed, therefore I decided to reward myself with little rudder play.
Here is shot from trial fitting of rudder lashings.
I like those simple & genius rudder fittings… There is some kind of primal pleasure in splicing rudder to the stern… and not paying some extra silver for expensive rostfrei attachments….
it has been long time since I last wrote to you… but, still, there have been some advancement in the Garage. What I managed to achieve is — despite of too cold spring (bad for epoxy cooking) and too hot early summer (hard to stay put in shady garage) — gluing coaming for main hatchway and constructing main hatch, glassing topsides of the hull (decks and cabin). Later process has been pretty emotional :p — getting glass over the upper deck stringers without air bubbles and sticking it onto underside of the sheerstringer was business that one may call PITA. Nevertheless, work itself is the best teacher and when I finally got into glassing the forward deck I managed to execute the process with minimal losses i.e. decently smooth finish, which requires minimal sanding later on.
So lets have a quick glance of the mess I have created (hull is turned so we could have a clear view of the sight).
1. exhibit A
– after fiberglass on deck and sides of the sheerstringer was wetted, next move was to try tap it into place underside of the sheerstringer using a brush. With not much of luck. Things got under control when I brushed undersides over with epoxy and WS Microlight filler.
Note that I have already covered up some of the traces (using good old elbow grease and 60 grit sandpaper).
2. exhibit B
– so here you can see me trying to get glassfiber down from cabin sides stick to underside of the sheerstringer, but this time, I didn’t cut the glass flush with the corner – instead I let the epoxy set for a while, then after it got really sticky, I removed the excess and applied fillet (Microlight) right a way on top of it.
Again, this evidence have had some touch ups already.
3. exhibit C
Well now I can be proud of myself and honor my humble figure with Distinguished Service Order as I demonstrated unprecedented capability to evolve and learn from past mistakes whereas this time (forward deck) I produced nice and neat fillets (Microlight) and let them set semi-hard before I moved to sheerstringers undersides with glassing. I removed the excess of the fiberglass just before applying saturation coat (mixed again with Microlight to avoid sagging).
PS! Decks and cabin sides saturation coat were thickened with Microlight, which is rather easy to work with (whether applying or sanding it).
So now the itinerary offers me adventure down under – fillets around the keel, aft deck sheerstringer undersides, stem & stern, sanding, fiberglass tape, sanding, glass for one side, sanding, glass for other side, sanding again…
So before stinging cold from Russia struck… I managed to glue fore deck as well. Aft deck was done already in November.
Now both of them are glued, trimmed back and rounded, ready for next phase.
During nighttime it drops down to -20 Celsius outside and it takes too much effort to heat garage sufficiently for epoxy work, so I spend some therapeutic hours shaping and smoothing rudder blades. Hopefully there will be soon some nice warm lows dispatched from North Atlantic so I could resume to gluing work, which means attaching the cabin sides and top, small round fillets for deck stringers, fillets for holes left by temporary screws I used occasionally during deck works.
Broadsides & bulkheads of the port hull were cut out already in summer. So for a change of scenery I started with gluing deck-beams and bunk bearers, also I prepared nice thickened-epoxy holes for taking inspection hatch bolts. Maybe its overkill… on starboard bulkheads I used just screws.
… then continued with beam web pairs, which also ended previous sanative session with a cruel fact that I miss few inches of ply sheet in order to complete all three pairs. Apparently when I produced rudders, stem & stern posts in spring, I went for too excessive safety margins…
Meanwhile I have prepared decks for gluing, this means attaching the stingers, epoxy coating and painting undersides. Loathed paintjob… This Tikkurila Temadur is indeed a quite nasty stuff working in under-ventilated garage I have there, but since it sticks into epoxy pretty well I guess I have to be pleased with it, no intention to get lost in the poly-carbonates maze again…This time I made my life a bit easier and bought proper thinner as well, which means I do not have to worry about short pot life anymore and also I can avoid slight coagulating problems I had previously when I was working too slow.
Anyway what I have recognized is that I have hit the 400 hour benchmark already, since I have worked at least 16 hours per week during summer months and at least 8 hours per week during spring & autumn. By no means I would like to contest Wharram estimates, Im pretty convinced that one could relay Tiki 21 within 400 hour time frame whether he is highly skilled or just a novice bloke who is desperately in rush to get onto the water soon as possible.
In my case… well I haven’t been a prompt starter all of my life. I need to develop a kind of feel of the process, tools and materials, only when I’m certain that those fresh spread wings will carry I would dear to dive head fist into the matter. Otherwise there is high probability that I will mess something up completely.
I had to castrate my inner perfectionist pretty much in the start anyway.
But furthermore I’m still struggling to fully disclose this little universe boiling there down in the garage. I guess its rarely not just a boat building for numerous amateur comrades out there. Building a 21 foot catamaran isn’t just a pastime endeavor for most us novices, Im pretty sure.
It just means just too many countless hours of researching, watching YouTube wow-to videos, fearing, hoping, being paranoid over the measurements, recollecting, digging out rare materials, spending money to gadgets you cannot do without, buckling down eternity on your knees with jigsaw, spending agonizing hours in folded position like a maniac flamingo, trying to spread fillets, then sanding fillets, after which reshaping fillets again because you messed up little bit in first time, and then again you are sanding those fillets and then back again behind your computer trying to make sense of all those controversial advice, opinions, dogmas, principles and tricks served in forums, DIY videos and blogs. Your knees hurt, your legs let you down, those dozens of tiny muscles you haven’t been aware of so far, those hurt as well, your nostrils are clogged, as well your brain, it has gone off due a short circuit, that’s because constantly you had to use both hemispheres simultaneously.
So whats the point of all? Its not easy to find a straightforward answer to this, I guess its just constellation of many small, often invisible things, thin threads spinning into taut line which may make up your safety rope in the end. All you have to to is just grab it and see where it pulls, or from where it pulls you out…
