Introduction: 10$ Stretch Wrap Kayak

We are going to make a kayak - a super-light, cheap kayak that can be used for fishing or just fun.

It will be made from branches and shrink wrapping tape. The skeleton will be held by packing/duct tape but can also be rope or string or wires.

It will take 2 days as wood needs to dry and take shape after debarking. 98% is making a frame, 2% is wrapping with tape

DISCLAIMER: Please use with caution and test at shallow water. Use flotation device. Supervise minors.

Supplies

Branches - straight branches of wood

-Body - 10 long 4m pieces

-Rings - 5 to 14 pieces of shorter, more flexible branches

2 rolls of "Scotch" tape or packing tape or duct tape (I used cheap $ store kind)

1 roll of wrapping / packing tape (main cost)

Wire (optional)

Knife - for cutting , de-barking

Saw - cutting branches

Step 1: Prepare Materials

In this step we are going to prepare materials for our kayak - long branches.

You need to prepare and debark 10 long branches or young tree shoots that are relatively flexible and straight. These will form skeleton of the boat. These should be 1-1.5 inches or 2.5 - 3.5 cm wide or thick. The should also be 3.5-4m long (preferably, 3m would also work but longer will make kayak more stable and give extra in case of screw up). Finally they should be green, not dead and dry as we need them to be flexible and able to bend into shape

You will also need 5-14 shorter branches for making rings. The amount of these depends on length and strength of wood. For example if you use spruce or willow, its branches can be thick yet still flexible and you can make a ring from one branch. But if you using another less flexible and less thick branch you might need to use two of them to form one ring.

After you cut them, get rid of side branches and leaves. Then debark the branches using knife or other tool. Debarking allows the wood to dry.

As soon as you debark it, set it in shape by using wooden pegs in the ground. Be careful and do not push the wood too much as it may snap. You may want to adjust pegs after half hour or 1 hour and bend branch more into desired shape. Continue / repeat for all pieces.

For the rings, if the wood is flexible you can bend into a ring in one go and use string to tie the ends together. If it is not so flexible , use pegs as in step above until you get horse shoe shape. You may also consider wrapping around a round large tree, but you likely need to drill attachments into your large tree to hold branch in place - I personally do not recommend this as it damages a fully grown tree.


Leave to dry for a day or two, preferably in the sun

Step 2: Assemble Kayak Skeleton

Assemble kayak skeleton:

1 Start by tying rings. Use scotch tape or duct tape. The central rings should be more oval with longer side on a horizontal axis. These rings should be approximately 0.6-0.7m (2-2.5ft) on long axis. The main entrance ring should be slightly large for ease of getting in and out. The rings closer to the ends should be smaller as sides would converge closer to the ends.

2 Start with central ring and tie two more rings to it on the sides. The longer side of oval ring should be horizontal. See pics.

3 Add side branches. Use longest branches you have. You may want to use some wire (or string) to catch the ends. Once done reinforce with tape

4 Add bottom branches. Use once branch at the bow and one at stern and attach them at the middle. at least 50% should be two of them together (overlapping), in other words double up . You want to have central part strongest. When adding long lines on the side cut the ends at 45 degree angle so that when they meet against central main branch they fit better together

5 Add the rest of the branches, ending with top central part.

Step 3: Wrap Kayak

Start closer to centre and move to one of the ends overlapping as you go. Just catch at one end or wrap on a branch and it will hold in place. Keep pulling pressure as you wrap. Best to have someone help you but if not tie rope to each end of kayak frame and then to a tree.

Do at least 3 layers. Wrap well at the bow and stern. At those spots as you get to the ends you may turn wrapping tape upside down to change directions.

You may want to catch some flapping wrapping tape ends with scotch tape

Keep pressure on when wrapping but keep in mind that cumulative force of wrapping tape will squeeze your skeleton together. If branches are thin, do not over wrap as branches may deform.

If you do not have any helping hands, you should attach a string to each end of the boat skeleton and then tie to a tree or post/beam, making kayak hanging (kind of like hammock). This way you can still wrap by yourself

Cut a hole on the inside ring of main entrance and attach on the inside of the boat. Cut 3 inches from the edge so you have enough to overlap on the inside. Catch that part with tape to keep from coming out

Step 4: Try It Out

Transport it to a water body and try it out.

Best to try in a safe shallow water first

Make sure you supervise minors and use flotation device

Enjoy

PS would love to see a pic of your kayak when you make your own

    Thank you for you comment. This is a fun project and not recommended for a serious mode of transport. I advise to take caution and supervision for minors. A lot of projects on here can be deadly, soldering something can start fire, electrical circuits can cause shock. I hope you don't take so serious

    Very nicely handled.
    During the shut down, our pool became a testing ground for all sorts of floating contraptions. We had never even considered stretch wrap. Brilliant

    Yes WB333 in your many years of life you surely know a few things. I don't dispute that and i quote from google regarding [ Disclaimers ] - in certain activities. They are designed to make sure that people are made aware of foreseeable risks of injury, or where responsibility will rest if items are lost, broken or stolen. Often when we take part in a ( potentially) dangerous activity, the organiser will ask the participants to sign a disclaimer to confirm ) as sense is apparently rarely common we have to assume disclaimers are an important aspect of this thread THAT IT HAS RISKS but we all don't come to by the way 1 of the only e-mail alerts I am genuinely/actively interested in a wide subject area interested in reading are from the great instructables site to read disclaimers .which have purpose i am sure . I/ we come to surely grow and learn from others who do know or are still trying to learn as a socially open approach to learning things we are not usually smart/knowledgeable about in specific areas often for me filling in some gaps in what I do know and learning some big words i have to google to understand enough to come up with ourselves without help and risk dying a horrible death and helpful community -techniques /ideas/inspiration to push our known boundaries of creating/designing something ourselves and yes this could definitely be a titanic iceberg scenario tragedy . if misused by a total fool who spent more time reading the Disclaimers than he did insuring he implemented all health safety and legal up to date inspections before its maiden voyage. have you tried making / testing this yourself ?? in a calm quiet controlled environment few feet of water perhaps fishing in margins even just basic tackle floating storage to keep baits/ hazards from cluttering narrow public paths with trip fall hazards that endanger adults/kids/pets safety on public paths . point is we could could moan all day about it or do it first nearly die horrifically then complain when we hurt ourselves at in A+E thinking about what have learnt from this experience and what not to do next time.Father son project in my opinion would be ideal which my 8 year old sons safe basic tool saftey/methods of been near body.s of water that he would have more chance of drowning in his paddling pool or bath but that is not the The point or even just walking to school and risk catching covid-19 is far easier And a lot more likeley Danger on my doorstep .one good thing getting him/and most of the younger generation/All of us off computers/devices and learning simple lessons like crossing a road guidance things same with water and instead of meaningless stuff from so called know it all's on you-tube .LIFES Too Short pal and no insult intended to anyone just mild humour to soften the tone of my opinion .I'm sorry for ranting I have come here for years spent hours on here and this is the first time I have ever felt the need to speak up and defend my poorly un-educated mind From Unsupportive Childish Negativitity (THANK-YOU CREATOR - {{SG19point3}} +PUBLISHING Great job and some great content ) for this very inspiring project and site in general. I am now going take my sons on a frame wood SAFE hunt in some fresh air!!... Will update our progres Soon to try and HEAR inspire and not judge . other people to share what Worked/works/sank/hit/ icebergs or nuclear submarines 🤞

    .PS - my opinion that the scotch /selotape BRANDED tape as i understand in uk as selotape [ Sellotape
    [ˈsɛlə(ʊ)teɪp]NOUN

    trademark

    1. transparent adhesive tape.synonyms:
      adhesive tapesticky tapeinsulating tapemasking tape parcel tape

    VERB

    1. fasten or stick with transparent adhesive tape."there was a note sellotaped to my door"
    could be wrong which is only temporarily taking much load of supporting the frame as Shrink wrap steps in 50/50ing the job evenlyholding. rapping of cling film must pull the frame inwards giving the kayak its overall strentgh/Stability surely?? sharing support with some similar idea as sellotape and perhaps backed up with string rope strong fishing line even and a thin coat of none toxic varnish ? to seal the wood?? to prevent moisture penetration especially at the cut points ? Ends of wood as we know very absorbing and possible warping mis-shapes over time again I could be wrong . If looking for something that is going to last time/light usage Storage just my few thoughts but i have not tested these methods [yet] any big definitely don't do's thoughts/Ideas would be thankfully listened to and taken onboard.. 🤣. hopefully i have not just spent the last 2 hours spell checking and googling for no reason Good luck people

    More practical than the blue tarp and pvc kayak project... but what about a combo of the two? A pvc frame with shrink wrap skin boat?

    I built a similar boat last year using PVC pipe, duct tape, and a plastic drop cloth. The PVC worked great. The drop cloth was a little challenging to make sit flat, I'm sure the plastic wrap is easier to work with.

    Great mind think alike :) This is exactly what I thought too, but at that point I had no access to pvc pipes. Next one I guess. I would use electrical tubing as it is more flexible or something like tent poles

    Can you upload a link to the materials? Or could you tell me where to get them? Also, what could you use instead of sticks? Thanks!

    I bought in a store and it wasn't in the States but if you google you stretch wrap. I am sure home hardware or Rona or Home depot will have that. https://www.walmart.ca/en/ip/duck-brand-clear-stre...

    Instead of sticks use electrical pvc piping. I think it will work great

    Fun project!

    One note: "scotch" is a brand that makes all sorts of tape. In the US "scotch tape" used generically means the little stuff use in wrapping gifts and such, which just would not do here. What you've shown in the picture is generically known as "packing tape", and any brand of it would do.

    Yes, you right, thank you! Just the brand name stuck in the brain. Some people call packing and some shrink tape as it shrinks when heated, but in any case plastic clear 15-20inch wide tape the airport bags are wrapped with

    Partially. Lake was muddy and not deep but in deeper water yes, especially with the sun
