Introduction: Construction Folding Boats From Polypropylene Sheet

I have already had experience in building boats "Skif" of wood. As a result of its use, I wanted to make the boat as light in weight and with the possibility of storage under the bed or under the wall in the garage.

Step 1:

Bring to your attention the process of building a folding boat made of polypropylene own design. The boat was conceived light, compact, reliable - stability, maneuverability and ample. I sailed on a boat over 300km and is fully satisfied with the result! Boat weight about 40kg in the assembled form. Board height 50cm, width 1.20 m, length 3,75m. Transported on a car roof. Very stability. Under the motor 3.5 hp with 4 people on board is 10km / h, with one person speed of 12km / h. Going on shore in 9 minutes.

When folded, the boat is a flat pack size 4 * 0.60 * 0.05 meters. Paddles and fin fit inside, sitting separately.

Step 2:

To build the boats need 4 pieces of 5 mm thick polypropylene. I chose 4m long sheets of them to get a boat length of 3,8 m.

First marked out the pattern on the sheet and cut out using a jigsaw. Next, using the manual milling machine cut grooves along the edges of the sheet to be able to bend side and bottom that allows you to fold the boat. Milling depth of 0.3 mm slot width 5mm.

You will also need 400 pieces of bolts m5 * 16мм and nuts, washers with a diameter of 15mm 800pcs, a tube of silicone.

The distance between the centers of the bolts is 27-30mm.

Further, the sides and the bottom are connected by means of bolts and nuts. Between the sheets used sealant. Assembly of the half boat check for leaks, collect water inside. Leak should not be. Next, connect the two halves of the boat and check for leaks again.

Step 3:

In the boat has three seats. It can is 4 people. Aft transom mounted to the motor. The seats are attached to the sides of the bolts. Under the seats installed units buoyancy foam. Under the seats and floating keel blocks is inserted to enhance rigidity.

Step 4:

General view of the patterns represented on the photo. Good luck!

Step 5:

And now the boat with steering and remote control gas and reverse.

Files with the plan board, and the bottom of the seat.

Step 8: One-handed Homemade Gas / Reverse Machine - (commander). Overview. Device, Assembly, Testing on the Boat.

Hello lovers of boats and boats!

Ever since I put the engine on the boat, I got the idea to install a one-hand gas / reverse machine. I didn't buy a ready-made one - I studied SolidWorks and made it myself, from scratch, I don't look at how the brand works.

Hello from Ukraine! We have a district in the city of Vinnitsa - it's called Korea :)
There were already followers from your country!
Ok, I'll send it to your mail. I recommend using stainless steel fasteners in salt water.
Good luck! 😊🤝

Hello asi2007_ukr_net,





you are a great designer and craftsman.This is the best self-built folding boat
I've seen.I use an inflatable boat for fishing.But that's a big task to always bring to
the water.I would also like to build myself a folding boat for this reason.Do you think you
can use a 5 hp outboard motor?I'm good at handwork, I can do it.I would be very
happy if you would send me plans and more detailed information on building your
boat.I would also like to know where to get the plastic sheets.





My email is: chimney125@t-online.de





Greetings from Germany

Hello asi2007_ukr_net,on your plans i can see that you made the milled grooves on the inside of the boat. I think the porta boat and the banana boat have grooves on the outside. The protective tubes are also located there in the grooves. Do you see an advantage when the grooves are inside?Best wishes

Hello, I am operating a boat with grooves on the outside.
I think it's better this way - the thin surface is hidden in the depth of the groove and so there is less chance of damaging it.

Many thanks for your answer,I think the same way too.I am currently planning the construction of the boat. I have already taken care of many things. The hardest part is getting the PP boards. They now have a delivery time of 15 to 20 weeks. Best regards

Thank you for sending the plans very quickly. That's very friendly.Can you tell us which sealant you used between the boards? Do you think the boat could also be built with a hatchback? And one more question: How deep did you mill the 5 mm wide grooves on the edges of the boards (0.3 mm in the text says that it doesn't seem deep enough to me so that you can bend the edges.). Many Thanks

Yes, please, I know from my own experience that when there is interest in a job, you need to do it quickly)
As a sealant, I used ordinary silicone for plumbing.
Didn't quite understand what a hatchback boat means - is it a closed deck? Or a cabin? What do you have in mind?
I milled exactly 3 mm, that is, 2 mm of material remains. At first, it is difficult to bend, but then it becomes easier and easier. I was afraid to cut through or leave little material. I think 2-1.5mm is ok. Do not make it thinner, this will weaken the seam.
How to address you, your name?) What city are you from?

Thank you for the feedback,My name is Karsten, I live in Frankfurt.A hatchback is a straight, upright stern. It's not bent. A straight board at the end of the boat. You can easily mount an outboard motor on the entire width and it stabilizes the boat better in the water. This is the case with most inflatable boats.Did you also put the silicone between the boards, or only on the seams?Thank you for your helpfulness. You rarely find that today.
