Introduction: "Building a One Sheet Boat" Alternate Building


Hello,

I build myself a "One sheet boat" like Vegra did https://www.instructables.com/member/Verga/

but with some minor changes as seen on the last pages




(btw: please ignore my grammar etc etc)

Step 1: First One of My Changes


My first change was that I cut down the Support frame from Vegras Original 32 inches to nearly 28 because i was to afraid that the plywood will break

Step 2: Second One...

Furthermore I decided to design stronger stem and stern post.

As you can see on the photos they look like mushrooms .

Edit: Added pictures

Step 3: Third One...

I also changed the Chine logs.

Other than Vegra i decided to double them for more Stabillity and damage consumption :)

See on fotos

Step 4: Fourth One...

At least I did some paranoid sealage work and some Beauty work

Sealant was Sikaflex for dockapplications

Edit: Added pictures.

Step 5: Paint !


I choosed for:

The inside white, the outside transparent and for the bottom dark grey Acrylic resin wich i got from a lokal diy store
I also added some covers for the stem post as you can see underneath.

The build time was a full month and I did it with my dad in the garage.

Also Thanks to Vegra for a nice instructables with no open questions to the project.


Step 6: Boat in Live Action!!!


Here is the requested in action Photo :)

As you can see i added the Water line in blue and the top egde and the lower egde in red.

I have been inspired by this and if all goes well I along with the local barony (S.C.A.) will be building a 2 section,30ft viking long ship based on this concept. Thanks for the inspiration, I'll post pics if we do it. ;b

Hi Guys,

the video i had is not really a testing video so i wil make a new if the weather is getting better.

Sorry for the wait

Best regards
Lars

PS.: Diy-Guy + Macrumpton, the video will be on youtube thats the most common i think.

author
jp armor (author)2011-10-12

i would also like to see a video please

DIY-Guy (author)jp armor2011-10-24

JP Armor:
Do you know how to download a video in a .pdf file? I think these instructions are great to have filed away on the computer, PDF files are easy to keep, search, and even print. Video is a bit less friendly to file and find.

author
macrumpton (author)DIY-Guy2012-01-06

Probably better to put the video on youtube and just link to it.

GoDu2 (author)2012-01-05

Good Idea! How about putting two side by side for a simple catamaran!

author
ctz (author)2011-09-29

My dad and I have being wanting to build a boat for a long tom and now I think I've found one that will work. GREAT INSTRUCTABLE :)

author
fweall (author)2011-09-14

I have followed your example and built a similar boat, extending the length by just over a foot and adding bulkheads forward and aft for storage/floatation, should be finished in a week or two, cant wait to get out on the water, cheers for the inspiration!

Nice nice,
i would love to see that in a instructable :)

Just writing one up the now, going to epoxy the hull this weekend! :-)

very well done.

author
MiloMaloCro (author)2011-06-27

please could you do a video of how it reacts in the water because I would like to see that...I'm considering to build one on my own but I'm not yet definitive about the design....

author
lazarus441 (author)MiloMaloCro2011-06-27

I will see if i have time to do so

author
MiloMaloCro (author)lazarus4412011-06-27

I'm looking forward

my father taught us how to built canoes out of a single sheet of marine ply by slitting one end of the sheet down the middle far enough down to make the bow (or both ends if you want a double bow) then lay the sheet in the sun and put wet hessian bags over the bow section. It will curl up from the humidity. Then a piece of timber cut to shape was nailed in to the bow and same for the stern. Strips of timber nailed along the free board for rigidity and they where very strong and light. Carried them literally for miles to the nearest dam when we couldn't get a ride.

claudg1950 (author)doggsboddy2011-05-12

doggsboddy: This is really interesting. We would like to hear more.
I guess that you didn't just slit the end of the ply, but you cut two tips (like the M letter in the McDonald's sign) so when they curve the two tips come together.
But it is my guess.
Lazarus441= great instructable and great work. Thanks a lot.

author
reblacke (author)doggsboddy2011-04-14

Sounds interesting. Any way you could do an instructable on that. I would be interested in learning how you built your canoes.

author
Truth Seeker (author)doggsboddy2011-03-27

Please show us what you mean!!!

author
chcagr (author)doggsboddy2011-03-27

That sounds VERY interesting. Could you make an instructable of that? I would love to see it in action.

author
billbillt (author)2011-03-27

Boat is great. My only complaint is you used machine tools to produce parts for this that most people can not afford. You should have done the complete project with minimal expensive tooling.

author
HappyToBeAlive (author)billbillt2011-03-27

So I am asking you this, if YOU had the tools to do the job, would you use em? or would you "do it by hand because some poorer folks don't have access to a mill"....

author
Tumunga (author)HappyToBeAlive2011-03-27

If I did it, I would use all the expensive tools, and have some migrant workers do the build for me. When it was finished, I would dress up in some farmer overalls, tell everyone I built it with a nail file, and a handful of dirt, and take pictures of the aforementioned nail file and dirt to post on here.

btw, nice boat.

author
matits (author)Tumunga2011-05-01

Nice. Migrant workers need work too. I wish I could afford the migrant work, let alone the tools. I may have to hop the border to Canada for work seasonally to afford the Southern migrant worker so I can afford to make the boat.

Any suggestions for the propellor attachment

author
whiteynut (author)billbillt2011-03-27

The milling steps could be done with a table saw, or set up a jig and make the cuts with a regular circular saw.

author
rlosiniecki (author)2011-04-20

I really like your instructible, great job!

I was thinking about tweaking the design a bit to make it a square back so I can use my 2hp motor.

Anyone have any thoughts on that?

author
fweall (author)2011-04-10

Nice boat, Im swithering whether to build something like this for fishing or a sit-on kayak. I much prefer working with wood, sure my flatmates would rather I used wood rather than foam insulation and fibreglass, just not sure which would weigh less as may have a bit of a carry to fish some lochs. Have you a pic of it with a person in it or did you do some displacement calcs? Cheers!

author
2DirtyKids (author)2011-04-10

Really nice, how much does it weigh? A picture in the water would be great.

author
ilpug (author)2011-03-23

i have been thinking of replacing my little canoe that i use for fishing, since it got holes shot in it by some mean person, and is kept afloat with duct tape. this looks like a great alternative! excellent project. enter it in the Epilog Challenge, i will give full marks.

author
swizzle (author)ilpug2011-03-27

Heat your boat up carefully with a blow torch and then put on the duct tape. It'll hold a lot better. Just don't burn a hole in your boat.

author
ilpug (author)swizzle2011-03-27

The boat is aluminum, so that might not work. i will probably rivet some little patches over the holes, and patch the rest with fiberglass.

author
swizzle (author)ilpug2011-03-27

They have a muffler repair kit that has some JB weld type stuff and some screening. Put that over the holes inside and out and it should hold tight.

author
ilpug (author)swizzle2011-03-28

yeah, i have some of that stuff. its called Bondo. might use it also

author
rdaggett (author)ilpug2011-04-06

If the holes are small it could be welded, use a steel sheet behind it the al filler will not stick to steel

author
ilpug (author)rdaggett2011-04-06

thanks for the idea, but i already patched it. i used some thin steel and small rivets to seal the holes, and then i used Bondo Auto-body filler to patch up around the edges, and smooth the outside. there were about a dozen holes, all large caliber, with jagged edges pointing out from the hull, so i had to hammer them flat and sand the rest. works fine so far, with no detectable leaks.

jackhg (author)2011-03-30

great job, really professional looking,,

do you think a sail could be some how rigged to the boat? could floatation foam be added to the bow and stern?

author
lazarus441 (author)2011-03-28

@ vincent7520 and brooklynlord
I was thinking about stainless steel screws but then decided otherwise because they where to expensive for the little amount that i needed and in my opinion brass looking screws would be better for the overall look of the boat.


@ vincent7520 again
The screws you can see are only for the look. the shine post on the outside are only glued with the sika and screwed from the inside. Also the acrylyc paint seals them a little.


Btw @ Hangfire I need to edit, they are galvanized .


@ billbillt
I tried one stem post at my table saw but the cut was to inaccurate for me, also i had trouble setting the angles up. So i decided to use the mill for a stressless building even thoug the mill died in between because on fuse was lose and we searched for the error for nearly 2 hours


@ KingOfCatfish
Okay i will but till then i can tell you about it when i was testriding it:
First of all i tried to sitting positions, one on the knees one sitting on the butt.
All along it was all wobbly in sitting and kneeing(i preffered kneeing, it felt a bit less shaky). the water line stood, with my 100 kgs in the middel of the side height. I asked a befreinded Boatbuilder what i can do about the shakyness and he advised to add a keel, which i will do in the summer time.

Did i forget a question?

Best regards Lars

Very nice work.
Seamanlike.
and excellent carpentry …
Much much better than the one you took your inspiration from ! ;)

Only minor question : why didn't you use stainless screw for you transom post ?…

Best wishes

Check out "Hannu's Boatyard", http://koti.kapsi.fi/hvartial/
Lots of very easy to build boats, 1 sheet, 1 and a half sheet (the Portuguese Style Dinghy" is awesome, I built two), and 2+ sheet boats.

HappyToBeAlive (author)2011-03-27

What a nice job! Wish I had built something like that with my Dad.

author
Bearclaw_Michael (author)2011-03-27

Great Father & Son project, you and your Dad did some real nice work on it.

brooklynlord (author)2011-03-25

Brass screws... are you sure?

If this is going to be used in seawater, then i suggest changing the screws. Unless the screws are made from 464 naval brass / naval bronze, they will corrode.

author
Hangfire (author)brooklynlord2011-03-25

those arent brass i dont think, i think theyre regular galvanized...

author
KingOfCatfish (author)2011-03-25

I love your work, it turned out wonderfully! I was wondering if you would uploading a picture of this boat in the water with someone in it. I'm considering building one and would love to see how well the displacement is and if I could carry just a little bit of gear in it. Thank you very much for any help and/or information you are able to share!

Great instructable! Cutting a Stem Rabbet with a Mill is a new
one on me.

author
lazarus441 (author)2011-03-23

@ Vegra:

thanks for the nice words :)
I you all suggest i should enter the contest then i will do it.
The boat doesnt have a name yet and that is with a reason. I want to add a keel because when i was testriding it it was all shaky because of the smaller width.

@ ilpug

I´ve got some leftover Sikaflex.. if you want i can send them to you :)

@ all

also thanks for the nice words :)

Best regards Lars

Having built a boat before I know how hard doing a good job can be ( I did only a so so job and hid it with paint!). your boat reminds me of a one sheet boat called the wacky lassie - the link is here- there are some good tips on that page as well.

http://www.alaska.net/~fritzf/Boats/Wacky_Lassie/Wacky_Lassie.htm

Over all a great build and nice outcome!

This is great. You made a number of changes that I had thought of. several of them I could not do because of the nature of the the race I was in (No adhesives, etc...) or could not afford,( The acrylic paint for the bottom, the bronze screws, etc......) or because of my size. ( I top out at about 200 lbs and wanted as wide a boat as I could get.
Yours looks really great and I really appreciate you linking to my Ible.
I wish you the best of luck with her, does she have a name yet? I suggest Shirley, because shw will surely get you across the water.
