Step 3: Cut Your "Ribs" and Prep for Bending.

Cut three pieces of wood to be used for "ribs" that will help you shape the boat.
I cut scrap 2X4s I had in half lengthwise.
The short rib for the front of the boat is 34", the center rib is 46" and the back rib is 43". Hannu suggests angling the cuts to help fit them in to the boat. I did not do this on the fist boat, but tried it on the second. If you know how to cut angles, give it a try. Might make things easier.

I set the two sides on the ground for ease.
For this first boat, I was alone when trying to bend the sides. Bad idea. Get someone to help you out. In this case I used these straps I had. I looped them over the sides so that as I tightened them the ends of the boat would come together.

Also note that in the second boat, below, I soaked the sides in water for a while before doing this step. I highly reccommend doing that. Hannu also has ideas for how to bend wood using a heat gun.

Now you're prepped. The next step is adding the ribs and bending the plywood.
<p>I started building one of these boats 6 years ago or so. I made a horrible mess with the fiberglass and set it aside for a while while I figures out how to fix it (an angle grinder was the answer. Finally finished it. I also cut a mattress to fit in it since I needed a bed for my daughter.</p><p>Now, unfortunately, My wife won't let me take it out on the water. Guess I have to make a second one!</p>
<p>Very nice instructable, congratulations.<br>I guess you would like to know more about the origin of the boat's &quot;style&quot; - Portugal. So, I invite you to take a look at <a href="http://acer-pt.org/vmdacer/index.php?option=com_content&task=view&id=538&Itemid=212" rel="nofollow">http://acer-pt.org/vmdacer/index.php?option=com_co...</a> (sorry, Portuguese only - check <a href="http://goo.gl/yWnimv" rel="nofollow"> http://goo.gl/yWnimv </a> for a Google translation).<br>The correct name is &quot;batela&quot;, and its primarily use was to transport people from land to anchored ships, and also, as you can see in the site, to go to the &quot;pesqueiras&quot; - fishing channels on rivers, namely the Minho river.<br>Nowadays they usually use small one-piece fiberglass boats, and this man is one of the last to know how to build this kind of boat. <br>The finishing is made with rubber paint - no need for beauty, I guess ;)<br>It took 4 hours (2 X 2 days) for a man, with the help of two others, to transform 9 pine boards into a boat.</p>
<p>Horrible Work.</p>
<p>fit to sail in sea? seems easy to build.</p>
Technically you could take it to sea. But they are very small and in rough weather I think you would have a problem.
if I may point out when you hunt and kill a trophy animal you should have it taxidermed as a momento i mean its not like they waste the meat they eat it and if your going to a hunting store expect that. p.s. my dad has several &quot;dead deer&quot; mounts. .p.p.s. you sound like a environmentalist.
Now I wonder if maybe some of those animals may have died from natural causes. Who knows? I'm not sure where they got the animals. But they definitely promote the killing of animals. <br>I suppose I am an environmentalist. I consider myself a steward of the planet. At least I try to be.
Thanks, I won't shop at Bass Pro Shop. I'm not surprised because they're also very fond of selling electric shock collars for dogs. When people kill animals simply for fun, there's not much they won't do.
Two things about understanding Hannu's diagrams: 1) reading his instructions above the diagram help in knowing where to start the measurement to a certain point, 2) he gives the distances in inches-and-eighths so 18&quot; 4 means eighteen and four eighths inches, or 18 1/2 &quot; In case you didn't spot them, when Hannu gives the instructions and diagram for the sides he gives them first for the 8' boat and then for a 6' boat.
I don't have specific dimensions. I ended up buying a metric and standard tape measure from Home Depot so that I could follow along with Hannu's instructions. Both boats were large enough for one average adult to row in.
Can I get the dimensions of the smaller boat? I can't understand Hannu's diagrams for my life :/
The correct term for the front of the boat is the bow and the correct name for the &quot;bow stick&quot; is the stem. The back end is the stern and that back panel is called the transom. 12 years with the Navy and 40 years in and around the merchant marine plus having a hobby building boats and I never once heard the term prow used except with Viking ships of old. Prow is a lubbers term for bow though.
If I built one of these I'd have to add a viking prow. A big carved dragon, that'd be cool!
I am thinking of building a kayak for my daughter with a removable dragon head. I would make it removable for taking off if the wind got high enough to blow the kayak off course with the head in place.
LOL! Thanks!
I want to build this boat as a end of summer project, but I'm confused on how to read the diagrams on the other website. How are you suposed to read it? (like the height of the sides of the boat)
Refer to the other website. Hannu has his instructions all in the metric system. As an American I regret to admit I had a hard time converting to the metric system as well. I suggest investing in a metric/standard tape measure. That is, it has metric on one side of the tape and the &quot;standard&quot; system on the other side. It will help you convert the measurements. After doing this project, I am convinced that the &quot;standard&quot;, or &quot;Imperial&quot; measurement system is silly. The rest of the world is metric, and Americans should just go with it. It's really much simpler.
I got your metric system right <a href="http://upload.wikimedia.org/wikipedia/commons/9/9e/M2_-_24th_MEU.jpg" rel="nofollow">here</a> for ya. 12.7x99mm my eye, that's Ma Deuce! She is 50 caliber through and through too. Yankee imperialism keeps the world free. Well, as free as it is ever going to be. Maybe if the rest of the world was more like us it'd be a better place?
Thanks, I started building the boat around 12:00 and finished the outside fiberglassing about an hour ago. going to try to do the inside and gunwales before dark.
Thanks for posting a great ible. <br><br>Not only have you inspired me to have a crack at building a boat of my own, but you also made some mistakes - saving me from doing the same. Thanks for including them.<br><br>I have just put my first coat of paint on the hull. Can't wait for sea trials. Hope she floats.<br><br>Here's a couple of ideas that worked for me and might help future makers:<br><br>1. Instead of the tie down strap to bend the sides, I just used rope and tightened it &quot;spanish windlass&quot; style, twisting the top and bottom parts of the rope with a stick. It worked really well tightening top and bottom evenly.<br><br>2. Just use resin and hardener for soaking the fibre-glass cloth or mat. There is no need to bulk it with saw dust. That just looks painful. Just paint some resin onto the timber, lay down the cloth, then dab more resin on to wet the cloth. Then use a roller to get the air out. The finish will be pretty smooth especially if you use a woven cloth.<br><br>3. To fill holes etc I made a putty from the fibre-glass resin and talcum powder. I found some in my wife's cupboard. It made my workshop smell like an Avon lady, but it works well. Just mix in enough to make a workable consistency.<br><br>4. Use Hannu's website. Both for instruction and inspiration. The gallery page has a lot of pictures from other makers and it's full of good ideas.<br><br>Thanks again. And to anyone tempted to try one for themselves: Just Do It!<br>
Here are some pictures of my effort.
personally I LOVE BASS PRO SHOPS(BPS) &amp; would never shop anywhere else for all the fishing I do. <br><br>as far as killing trees to decorate the store, most if not all the trees that I have seen there, are fake trees...the animals are also MOSTLY fake. Fake meaning the heads &amp; such are man made no real animals are killed and/or used to decorate their stores. <br><br>I know this because I used to work for BPS in the Headquarters in Springfield MO. <br>I say used to because stage 4 cancer destroyed any chance I ever had at holding any kind of job ever again.
I pray for your recovery from such a horrid disease. If not recovery then perhaps some joy or other good will be at the end of that battle. So many have gone and yet we have failed to find an easy cure.
TY Sir.<br>May Allah(swt) be with you always.
So what is your best estimate as to the cost to build these boats? <br> <br>Is it worth it? They look great and fun!
I wish I would have kept closer count. It is also hard to say because I had many of the tools and supplies already. I would ball park $200. About $100 per boat. But it would vary from there. <br><br>I think it was worth it. If I were to do it again I may forego the oars and find a trolling motor on craigslist. <br><br>It also is better to have a place to use them available. It is hard to haul them out to a lake every time you want to use them. <br><br>If you do it, send along pictures!
I built two of these several years ago out of regular 1/4 inch ply. Actually I used two layers of plywood. The finished product wasn't a great deal harder to handle than a one ply boat, and I could get both boats in the back of the pickup (turned on their sides). They will also work well with a small trolling motor, or a regular motor up to about 5 HP. The boats lend themselves easily to modifications. I am in the process of building another that I hope will be stronger and speedier than the other two.
This looks a wee bit small for fishing, but then again, I'm claustrophobic.<br><br>I like the boat! you explained it well, the pics helped tie together any loose ends, &amp; the safety tips, I love it!!!<br><br>this is a good boat for toying around in the water, I think maybe you could even add a 3.5 HP outboard (I would NOT go any larger than that tho). This was an enjoyable read.<br><br>I think it would be very easy to build a bigger boat based on what you have done here....<br><br>You did good!! TY for sharing. <br><br>Oh Yeah, if I came across a wee bit harsh about BPS, I appologize. It's just that BPS is my &quot;go to&quot; Store for all my fishing gear.
Thank you for the Instructable - it really fills in some information gaps in Hannu's instructions. <br><br>I was curious, how much epoxy did this project take? I'm curious what volume I should purchase.
Buy the big one. I used fiberglass, which has two parts to mix together. Home Depot sells a big metal can and a small can. I went through several small cans and finally sprang for the big can and used most of that. Start with the large amount. The amount it takes depends on how thick you lay it in and how wide you put it on and how many coats you put on. Hope that helps!
Thanks, that is a big help. I'm starting one this weekend with a buddy. I'll send pics when it's done. Thanks again!
Good luck! Wear a respirator, goggles and clothes that cover your skin. That fiberglass is nasty stuff.
I've been meaning to get back on here for some time to thank you for your contribution.<br><br>I wasn't terribly confident in following through with this project so I went CHEAP CHEAP! lowest grade plywood and scrap lumber for everything else...<br><br>Once I had put the first boat together I was impressed - so I went whole hog with the quality of paint and adhesives I used - three seasons later it's still a sound water tight little rig.<br><br>I'd recommend this instructible as a first time boat building venture to anyone!<br><br>Thanks again.
Sweet! I'm glad it worked for you. I'd like to see pictures of your boat if you can share them.
well this give you an idea of it's capacity - it wasn't a pleasure cruise - but it got us out to the sailboat - three adults and a bit of gear...
Wow! I had oars with mine so I couldn't fit other people in my boats, but with a trolling motor, I guess three could just fit in there. Don't rock the boat!
Forgot to say I did enjoy this &quot;ible&quot;.
I would prefer talcum as a filler in epoxy. It is more inert than flour or sawdust.<br />
Is it possible to sail with a right-triangle sail that has only a mast and sheet, no booms or sprits or anything?
Technically yes, but...<br /> <br /> 1) It will be really difficult to get the boat to behave in very light winds. There is nothing to hold the sail in the position you want, and you may well get tangled sheets, flogged by the mainsheet etc.<br /> <br /> 2) you'll probably find that the boat won't point very high into the wind (though a lack of centreboard will be far more of a problem at this point)<br /> <br /> 3) you don't really want the sail to be a flat triangle, you want the sail to be a curved shape (think of an aeroplane wing cross section). This isn't that hard to do, and you can experiment with plastic sheeting and gaffa tape.<br /> <br /> So the answer is a cautious 'well you could..'&nbsp; Honestly though for the price of a bit of old banister or equivalent and a few extra bits of rope, I'd probably stick with a boom. The extra effort making it would easily pay off in terms of faffing/ cursing time later.<br />
does soaking the wood damage the inside?
No, not once you coat the inside of the boat/wood with some sort of sealant. The hot/warm water temporarily loosens the wood fibers so it can bend. Once it dries, you just coat the inside with some sort of sealant. In my case I used Deck Stain. Paint, or polyurethane or something better would be advisable.
What Do U Do About The Cracks On the Side Of The Boat
Like he said, wear long pants and shirt sleeves. tape the sleeves and pants legs around your ankles and wrists. Put a towel over your head and around your neck and tape it too. Any exposed skin cover with Vaseline. If you mess up and leave skin exposed, it will itch like you never itched before. rinse the area with alcohol first them cold water. NEVER HOT WATER. it opens the poors in your skin and the glass gets into them and it itches for days. Be especially careful about breathing the dust.
will the boat work if i don't sand the fiberglass down? i really don't have the finances for a mask and all that business.
It should. Try hard to keep the fiberglass smooth as you apply it and you wouldn't need much sanding. You could get away with hand sanding. If you mix something in to the fiberglass, use flour. The sawdust is what makes sanding necessary.
great thanks. now about how much weight will this hold?
The boats will hold one full sized person about 250 lbs. More or less. Hope that helps!
I like the smell of fiberglass....ha....hahaha.....haaaaaa...dizzy.......im high.......hahahahaaaaaaaa. Use a ventilated room or be outside when using that stuff or burn some brain cells....hmmmmm
Eight miles high...
