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.

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.

Step 6:

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

<p>Nice job bro. I&rsquo;m Amir and I&rsquo;m from Malaysia. I just want to ask you<br>about the material that used for the hull. I saw that you used PP sheets. What<br>if I use HDPE sheets instead of the PP sheets and what&rsquo;s the pro and cons<br>between the two materials for building the folding boats? Glad if you willing<br>to share. I can be contacted via WhatsApp +60192644102 or email<br>ultegraxt@gmail.com</p>
<p>But, i dont have plans in pdf, vector. I have plans on a paper:(</p><p>I specifically made boats photo pattern with a high position so you can increase them without strong distortions.</p><p>To translate the drawings into electronic form I need time and opportunity to do so. </p><p>And I do not know how to do it efficiently. </p><p>How long do you want to do a boat? What is your name? </p>
<p>Please plans in pdf, vector etc. Thanks from Brazil. euripedessolucao@hotmail.com</p>
<p>How did You prevented wrinkles in the process of &quot;folding&quot; the fastening curved edge? (see the attached picture to better understand what i mean) </p>
<p>Hello. Unfortunately, the pattern of the boat is not in PDF format, there are patterns on paper. Principle to get a pattern you need to increase and draw the outline of parts of the boat in the picture where there is a view from above. I am sending you this picture. If you are familiar with your computer is not difficult.If you could not, I'll try to make the photo paper patterns in high quality pictures.</p><p>Glad you liked my design. I added a video where the boat had steering and remote motor control.</p><p>https://www.youtube.com/watch?v=CJp0R-h2gfA</p><p>Good luck!</p>
<p>Hi, I really like your work on this nice folding boat :)</p><p>I am wondering if your plan for dimension of the pattern is available if I go pro on this site and download the PDF version ?</p><p>If not, can you made it available for others like me that would want to build a boat like yours to enjoy it on lake ;)</p><p>Thanx a lot !</p>
<p>This reminds me of a porta-bote, the old style with the small motor mount. New Porta-botes seem unbelievably expensive. I basically had one given to me some years back, and received many hours of pleasurable fishing with it.</p><p>How much did your build cost? Where do you source your polypropylene sheet? Can the polypropylene sheets be purchased in various lengths? </p>
<p>PP sheet buy from companies that are engaged in the construction of swimming pools and water tanks. It is best to use a sheet of 4m * 2m, then Pattern boats without waste. Bought at the price of $ 30 per 1m2, ie $ 240 PP + 500 pcs of bolts with nuts and washers + tube of silicone sealant. For the manufacture of leather material used for shelves + foam.</p>
<p> Wonderful !</p><p>You made it at home. Here is our boat made from 4 mm polypropylene sheet,and it's somewhere weird at least i think so. if possible,i want to discuss with you to improve. here is the link http://youtu.be/7eYN99DjbLE</p>
<p>Thank you for rating. What would you like to discuss?</p>
<p>So, now looked your video boats. You did? Original. I'm such a structure has not yet been seen. But I think for a quick trip, it is not necessary, and I am perplexed by the buoyancy of the blocks on the sides. But all in all very interesting. Where are you from?</p>

<p>A folding boat! That's awesome! I didn't find it very clear from the photos but what is the process of folding and unfolding? How long does it take?</p>
<p>Unfortunately no photos of the process of dismantling. The boat is going for 9-10 minutes. I made a boat for 4 days.</p>
<p>Brilliant!</p>
<p>This is so cool! Definitely a modern way of boat building! Thanks for sharing!</p>
