Comfort on the water is not just a pleasant bonus, but a necessary condition for maintaining back health and productive fishing. Sitting on a hard transmolina jar And when you're on the move, it becomes a challenge that quickly tires even the experienced angler, which is why many boat owners are thinking about upgrading the interior, and the best solution is to get rid of it. chair-chairHowever, ready-made store options often turn out to be either overly expensive or not fit in size to a particular boat model.
Creation boat-chairs DIY It allows you to perfectly adapt the seat to your anthropometrics and the design of the vessel, and you can choose the height of the backrest, the rigidity of the seat and the angle of inclination, which is critical for long transitions. sea-plywood and specialized alloys that guarantee the durability of the structure in an aggressive aqueous environment.
In this article, we will look at all the steps to creating a reliable and comfortable seat, from the choice of materials to the final mount to the bottom, you will learn how to avoid the typical mistakes of beginners and create a design that will not rot, rust or stagger under load. Competent approach to design It will allow you to enjoy fishing, rather than thinking about a stale back.
Selection of materials and preparation of tools
The first step to making a quality product is to get the right raw materials, and the basis of any good chair is a material that is resistant to moisture, temperature changes and ultraviolet light. aluminum Or a square tube, because steel requires complex corrosion treatment, and wood can dry, and aluminum is lightweight, non-rust, and easy to process at home.
For the seat and back, the ideal solution is plywood It's at least 10 to 12 mm thick, and it's soaked in special compounds that prevent it from coming into contact with water, and if you have a budget, you can use conventional birch plywood, but you need a quality, high-quality plywood. epoxy Plastic elements, such as ready-made backs from car seats or garden furniture, can also be an excellent base.
Don't forget about the fasteners. All bolts, nuts and washers must be made of stainless steelOrdinary ferrous metal will rust after the first season, leaving rusty streams on the sides of the boat and weakening the structure, and you will also need tools: an electric jigsaw or a circular saw, a drill, a grinder and a set of wrenches.
⚠️ Warning: When working with an aluminum profile, avoid direct contact with copper wires or tools in the environment, as this can trigger electrochemical corrosion, which quickly destroys the metal.
For upholstery, the material with marking is best suited Oxford 600D or PVC fabricThese materials do not absorb water, dry quickly and are resistant to mechanical damage, the use of foam inside the seat should be minimal, or should be used. polyethyleneIt does not draw water even when the outer shell is damaged.
Design and sizing
Before you pick up a saw, you need to create a detailed drawing. Ergonomics of the chair It has a direct impact on comfort: too low a landing makes it difficult to control the engine, and too high can shift the center of gravity of the boat, which is dangerous on the wave. The standard height of the seat from the boat floor is 35-40 cm, but this parameter can be adjusted depending on the height of the angler and the type of boat.
When designing, note that the chair should not interfere with movement on the cockpit. the width of the back usually varies from 35 to 45 cm, and the depth of the seat is from 30 to 40 cm. If you plan to install the chair on the rotary mechanism, lay additional centimeters for the radius of rotation. Accurate measurements The interior space of your boat will help to avoid a situation where the finished product simply does not stand in place.
It's important to have a mounting system. Inflatable boats are the ones that are most commonly used. lift-system Or attachment to existing banks, whereas metal boats can weld the back parts or use powerful rods, the drawing should include views from the side, front and top, showing all the holes under the fastener.
Formula for calculating sustainability
To calculate the stability of the chair, use the ratio: the width of the base should be at least 70% of the height of the center of gravity of the seat, which will prevent rolling over in sharp rolls.
Manufacture of the frame and seat support
The assembly process starts with cutting the materials according to your drawing. If you're using an aluminum pipe, cut the lengths you want to do with 45 or 90 degrees to dock. The scaffold elements are best connected by using the help of a carcass. elluminium And then welding aluminum with special equipment and skills, so for beginners, bolting is preferable.
For the base of the seat, cut two rectangles from plywood: one for the seat, the other for the back. The edges of the parts must be carefully polished to remove the burrs and prevent damage to the upholstery. Then drill the holes for the fastener, pre-marking the installation site. loop All plywood slices must be treated immediately with a protective compound.
Collect the frame on a flat surface, checking the diagonals to avoid distortions. Strength of construction If the chair is high, be sure to include additional struts or triangular headscarves at the corners of the junction of the pillars and the base.
⚠️ Note: When drilling holes in aluminum, use a coolant or oil so that the drill does not “stick” to the metal and the hole is smooth, without melted edges.
☑️ Frame assembly control
Sheathing and finishing
Once the skeleton is assembled, it is time for the aesthetic and tactile parts of the work. sail-varnish It's going to create a sealed film that protects the tree from rotting, so each layer has to dry completely before the next one is applied, and the interlayer grinding will provide perfect smoothness.
To create a soft seat, use a sheet foam 3-5 cm thick. Cut the blanks into the shape of plywood foundations and glue them with a special glue for porous materials. It is important not to make the seat too soft, otherwise you will constantly "fall over" on fishing, which upsets the balance. Oxford Or leather.
Use it when you're tightening. kaporonThe seams must be double or triple for strength, the fabric is pulled evenly, without folds, and fixed on the back of the plywood with stainless steel brackets or special furniture nails, and decorative elements such as plastic edging can be added.
Use perforated fabric or make holes in the base of the seat to drain water – this will allow the chair to dry quickly after rain or splashing.
Installation of a chair in a boat
Installation of the finished product in a boat requires special attention to safety. For PVC boats, it is absolutely impossible to drill cylinders. overlayFor aluminum boats (for example, Kazanka or Voronezhanka), you can use powerful rods or weld the response parts to the bottom if the chair is stationary.
If you're putting the chair on the rotary mechanism, make sure it's securely fixed, the back of the chair can cause a rolling injury, and check if the back of the seat is intruding when you turn and if it's not in the way of steering. boat-engine Ideally, the chair should be able to quickly dismantle.
So you do the test first on the shore, simulating the roll of the boat. You sit in a chair, you sway from side to side. The design has to withstand dynamic loads without squeaking or deformation. Only after successful trials can you get on the water.
| Materials | Pluses | Cons | Recommended application |
|---|---|---|---|
| Aluminum profile | Light, non-rusting, durable | More difficult to process, more expensive steel | Frame for any type of boat |
| Sea plywood | Waterproof, hard, affordable | Requires high-quality processing of edges | Seat and backrest base |
| Stainless steel | Maximum strength, durability | High weight, high cost | Fastening, turning mechanisms |
| PVC fabric (Oxford) | It does not absorb water, it is easy to clean. | Could fade in the sun. | Seat upholstery |
The main principle of installation is the absence of direct damage to the hull of the boat (especially for PVC) and ensuring maximum rigidity of the seat mounting.
Care and operation of a homemade chair
Even the best quality homemade product requires maintenance, and after every fishing trip, especially in salt water, the chair should be rinsed with fresh water. Salt deposits Even stainless steel and aluminum can break down with prolonged exposure, and it is better to remove and dry the fabrics in a straightened form to avoid mold formation in the folds.
Check the condition of the fasteners regularly. Vibration when the motor is running can weaken the nuts, so use it once a season. prophylactic If you notice damage to the lacquer coating on the wooden elements, immediately grind and paint over the area to prevent moisture from entering the structure of the tree.
Keep the chair dry, disassembled or folded, don't leave it outdoors in the scorching sun or snow for the winter, and properly stored will extend the life of your creation for years, while maintaining its appearance and functionality.
⚠️ Warning: When storing, do not put heavy objects on soft upholstery - this will lead to irreversible deformation of the foam and loss of seat comfort.
The Secret of Longevity
Once a year, lubricate all movable joints (loops, swivel mechanisms) with silicone lubricant, which is not washed away with water and protects against corrosion better than conventional oils.
Possible errors in the manufacture
Many beginners make the mistake of choosing too heavy materials in pursuit of “unkillability.” Overweight The chairs reduce the boat's load capacity and impair its performance. In small craft, every kilogram counts, so aim for the optimal balance between strength and lightness.
Another common mistake is ignoring the center of gravity, and a high chair without a broad and stable base can cause a boat to tip over when a fisherman moves abruptly. structural stability And if necessary, make the base wider, even if it takes up a little more space.
Hard plywood without the proper layer of cushioning will turn fishing into torture, use quality materials that retain shape and do not follow after the first season of active use.
If you are making a winter fishing chair, consider installing an additional insulation or cover, as metal and plastic become icy in the cold.
Can you use conventional plywood instead of sea?
You can use conventional plywood, but the life of this chair will be much shorter, and you'll need to treat all the faces with epoxy and coat them with several layers of waterproof varnish, but the risk of stratification from constant contact with water is still high.
How much weight can a homemade chair withstand?
When using aluminum profile 20x20 mm and high-quality assembly, the chair calmly withstands the load of up to 150 kg. The main thing is to correctly calculate the points of support and not to make too long console departures without additional racks.
Do I have to make armrests?
Armrests are often intrusive for fishing, especially when working with tackles or oars. However, if the chair is designed to rest or control the engine, narrow armrests can increase comfort.
How to secure a chair if there are no seats in the boat?
In this case, the optimal solution would be to manufacture a separate platform-base, which lies on the floor of the boat and is fixed with its dimensions or light hooks for stringers.
What is the best way to cut an aluminum profile?
It is best to use a metal hacksaw with a small tooth or a special aluminum disc on a Bulgarian (observing safety precautions). Conventional wood discs can bite the metal, which will lead to a breakage of the tool or injury.
