Spread the love

If you’ve ever want­ed to build your own boat, a jon boat is a great place to start. A jon boat is a flat-bot­tomed ves­sel that’s ide­al for fish­ing in shal­low waters. It’s a rel­a­tive­ly easy build, so even an inex­pe­ri­enced boat builder can tack­le it with con­fi­dence. Here’s how to build a jon boat.

How to Build a Jon Boat

To build a Jon boat, you will need a set of plans or a kit with the nec­es­sary mate­ri­als. You will need to cut the ply­wood pan­els to the required size and shape accord­ing to the plans, and then assem­ble them using screws, nails, and marine-grade adhe­sive. Once the pan­els are assem­bled, you will need to rein­force the seams with fiber­glass tape and resin. You will need to install the hard­ware com­po­nents, such as the motor mount and seats, and apply a pro­tec­tive coat of paint or var­nish.

  1. Gath­er mate­ri­als and tools. You will need ply­wood, marine grade epoxy, screws, saws, and oth­er tools.
  2. Cut the ply­wood for the hull accord­ing to the plans. Make sure to take mea­sure­ments and use a jig saw for the most accu­rate cuts.
  3. Drill holes for the screws that will secure the pan­el­ing to the frame.
  4. Assem­ble the frame and secure the pan­els with screws.
  5. Apply marine grade epoxy to the seams and edges of the boat.
  6. Install the boat seat, motor, and oth­er acces­sories.
  7. Paint the boat with an out­door, water­proof paint.
  8. Test the boat in a body of water.

Before start­ing the build, it is impor­tant to ensure you have all the nec­es­sary tools and mate­ri­als. You will need a saw, drill, sand­pa­per, fiber­glass tape and resin, screws, nails, and marine-grade adhe­sive. It is also impor­tant to make sure the ply­wood you use is marine grade and pres­sure-treat­ed so that it can with­stand the ele­ments.

Gather the Necessary Materials

In order to com­plete a project, you will need to gath­er the nec­es­sary mate­ri­als need­ed for the task. Depend­ing on the project, this may include any­thing from tools and sup­plies to instruc­tions and dia­grams.

  • Alu­minum Sheets: Alu­minum is a pop­u­lar mate­r­i­al for jon boats due to its light­weight and cor­ro­sion-resis­tant prop­er­ties. You will need alu­minum sheets to con­struct the hull and oth­er struc­tur­al com­po­nents of the boat.

  • Riv­ets or Weld­ing Equip­ment: Depend­ing on your pre­ferred con­struc­tion method, you will need either riv­ets or weld­ing equip­ment to join the alu­minum sheets togeth­er. Riv­ets are com­mon­ly used for small­er boats, while weld­ing is pre­ferred for larg­er or more com­plex designs.

  • Tran­som Mate­r­i­al: The tran­som is the ver­ti­cal sur­face at the rear of the boat that sup­ports the engine. You will need a strong and durable mate­r­i­al, such as marine-grade ply­wood or alu­minum, to build the tran­som.

  • Floor and Deck­ing Mate­r­i­al: The floor and deck­ing of the jon boat can be con­struct­ed using marine-grade ply­wood or alu­minum sheets. These mate­ri­als should be stur­dy and able to with­stand the marine envi­ron­ment.

  • Sup­port Beams and Braces: To rein­force the struc­ture of the boat, you will need sup­port beams and braces. These can be made from alu­minum or oth­er suit­able mate­ri­als and are used to pro­vide addi­tion­al strength and sta­bil­i­ty to the boat’s frame­work.

  • Hard­ware and Fas­ten­ers: Var­i­ous hard­ware and fas­ten­ers will be required, such as screws, bolts, nuts, and wash­ers, to secure dif­fer­ent com­po­nents of the boat togeth­er. It is impor­tant to choose marine-grade hard­ware that is resis­tant to cor­ro­sion.

  • Seal­ing and Bond­ing Mate­ri­als: To ensure the boat is water­tight, you will need seal­ing and bond­ing mate­ri­als such as marine-grade sealants and adhe­sives. These are used to seal joints, seams, and oth­er poten­tial points of water entry.

  • Paint and Pro­tec­tive Coat­ings: Once the con­struc­tion is com­plete, you will need paint or pro­tec­tive coat­ings specif­i­cal­ly designed for marine use to pro­tect the boat’s exte­ri­or from cor­ro­sion and dam­age.

  • Safe­ty Equip­ment: While not direct­ly relat­ed to the con­struc­tion process, it is essen­tial to have safe­ty equip­ment such as life jack­ets, fire extin­guish­ers, nav­i­ga­tion lights, and oth­er required safe­ty gear on board your jon boat.

It is impor­tant to make sure that you have all of the mate­ri­als you need before get­ting start­ed.


You’ll need 2”x4” boards for the frame­work and 2”x6” boards for the sides. You’ll also need 1”x4” boards for the seat, and 3/4” ply­wood for the bot­tom.


You’ll need screws, bolts, wash­ers, and nuts to attach the lum­ber. You’ll also need ring-shank nails for attach­ing the ply­wood to the frame.

Paint and Sealant

You’ll need a good qual­i­ty marine paint to pro­tect the wood and a sealant to water­proof the hull.


You’ll need basic tools such as a saw, drill, screw­driv­er, and ham­mer.

Design Your Boat

Design Your Boat

Before you start build­ing, you need to decide on the design of your jon boat. Con­sid­er the size, shape, and type of boat you want. Make sure you take into account the type of water you’ll be using it in, as well as the type of fish­ing you’ll be doing.

Sketch Out the Details

Once you have an idea of the design, sketch out the details. This will help you visu­al­ize the boat and decide where to place the seats, oar­locks, and oth­er fea­tures.

Decide on the Hull Type

There are two com­mon hull types for jon boats: a flat-bot­tom hull and a V‑bottom hull. The flat-bot­tom hull is ide­al for shal­low water, while the V‑bottom hull is bet­ter for deep­er water and rougher con­di­tions.

Build the Frame

To build the frame for a jon boat, you will need to assem­ble the ribs, keel, and transom. Start by mea­sur­ing and cut­ting the ribs to the desired length and shape, then fasten them to the keel using screws or nails. Attach the transom to the ribs and keel using screws. You can use a piece of plywood to join the ribs and transom togeth­er, cre­at­ing the frame of your jon boat.

Cut the Lumber

Using your design, mea­sure and cut the lum­ber to size. Make sure the boards are straight and the cuts are square.

Assemble the Frame

Once the lum­ber is cut, assem­ble the frame. Use screws to attach the 2”x4”s and 2”x6”s, and make sure every­thing is square.

Attach the Seat

Once the frame is assem­bled, attach the seat. Use screws to attach the 1”x4” boards and make sure every­thing is lev­el.

Attach the Plywood Bottom

Attach the Plywood Bottom

To attach the plywood bot­tom, you will need to use wood screws. Start by pre-drilling holes into the plywood, mak­ing sure to keep the holes slight­ly small­er than the screws. Next, attach the plywood to the bot­tom of the struc­ture using the wood screws. Make sure the screws are tight­ened secure­ly, then you can add any addi­tion­al hard­ware or acces­sories need­ed to com­plete the project.

Cut the Plywood

Mea­sure and cut the ply­wood to size. Make sure the cuts are square and the boards are straight.

Attach the Plywood

Use ring-shank nails to attach the ply­wood to the frame. Make sure the nails are secure­ly fas­tened and the boards are lined up straight.

Seal the Hull

Once the ply­wood is attached, it’s time to seal the hull. Use a good qual­i­ty sealant to water­proof the hull and pro­tect it from the ele­ments.

Paint the Boat

Once the boat is sealed, it’s time to paint it. Use a good qual­i­ty marine paint to pro­tect the wood and make sure it looks good. To paint a Jon boat, you will need to start by clean­ing the sur­face of the boat and remov­ing any exist­ing paint or oxi­da­tion. You will need to sand the sur­face of the boat to cre­ate a smooth sur­face for the new paint to adhere to. Then, you will need to apply a primer and let it dry. Once the primer is dry, you can then apply the paint of your choice. After the paint is applied, let it dry and apply a clear coat to pro­tect the paint. Inspect the boat for any imper­fections and make sure it is ready for the water. Once the boat is paint­ed or camoed, it’s time to fin­ish it. Add the oar­locks, cleats, and any oth­er fea­tures you want.

Launch Your Boat

Once the boat is fin­ished, it’s time to launch it. Take it out for a test run and enjoy your new jon boat. Build­ing a jon boat is a rel­a­tive­ly easy and reward­ing project. With the right mate­ri­als, tools, and design, you can build a stur­dy and reli­able boat that will last for years. So gath­er your mate­ri­als, design your boat, and get ready to launch your new boat.

Before you launch your boat, make sure you have all the nec­es­sary safe­ty equip­ment, such as life jack­ets and flares. Also, make sure you under­stand the laws and reg­u­la­tions for oper­at­ing a boat in your area. And always prac­tice safe boat­ing.

To keep your jon boat in top con­di­tion, it’s impor­tant to do reg­u­lar main­te­nance and upkeep. Inspect the hull and hard­ware reg­u­lar­ly and make any nec­es­sary repairs. Also, be sure to clean the boat after each use and store it in a secure area when not in use.

Enjoy Your Boat

Build­ing a jon boat is a fun and reward­ing project. Once you’ve fin­ished build­ing it, you can enjoy fish­ing, cruis­ing, or just relax­ing in your new boat. So get out there and enjoy the water!
