Legendary OBE 1 While it remains one of the most popular aluminum boats in the post-Soviet space, its age dictates its operating conditions, owners often face the need to improve the performance, comfort and safety of the vessel, which was originally designed in an era of shortages of materials and technology. tuning boat Ob 1 It is able to turn a utilitarian flat-bottomed boat into a full-fledged boat for fishing and recreation.

Modernization does not require engineering education, but requires a careful approach to the details of the structure. It is important to understand that interfering with the geometry of the hull or shifting the center of gravity can dramatically change the behavior of a vessel on the water. In this article, we will discuss time-tested solutions, drawings and practical tips for refining that will make your day on the water. Obi. Safe and pleasant.

Before you take up the tools, you need to conduct a thorough audit of the current condition of the case, only after making sure that there are no hidden cracks and corrosion, you can start installing additional equipment. It is critically important to check the thickness of the bottom and sides before starting work, since drilling of weakened metal can lead to instant flooding.

⚠️ Warning: Any changes to the shell design not provided by the manufacturer may require re-registration with the GIMS. Keep all material checks and make a photo report in case of questions from the inspectors.

Analysis of the standard design and identification of weaknesses

Construction OBE 1 It's simple and reliable, but it has a number of design features that modern owners consider disadvantages: D16AT duraluminium is the main material, which loses strength over time in stress zones, and the first thing to do is assess the condition of welds and rivet joints, because they are the first ones to react to motor vibration.

The standard flooring is often criticized for its ease and lack of rigid fixation. in choppy conditions, the boards rattle, creating an unbearable noise that scares the fish and tires the crew. In addition, the factory layout does not provide convenient storage spaces for gear, which causes fishermen to huddle in a tight cockpit.

Another weakness is the slab, which is attached directly to the transom, which, when you install powerful engines (over 15 hp), causes the side to deform and cracks in the corners, and strengthening this zone is a priority in tuning.

  • 🛠️ Lack of regular knobs for storing things and equipment.
  • 🔊 The sound of the swelling (the sling) is a strong wave.
  • ⚓ Inconvenient shape of the nose for anchoring and mooring.
  • 🌊 Low sides in the nose, which leads to splashing of the cockpit.

Understanding these issues allows you to form a clear plan of improvements, not try to implement all the changes at once, it is better to move in stages, starting with strengthening the body and improving buoyancy.

Body reinforcement and transcension modernization

The first step in serious tuning OBE 1 The standard aluminum often can't withstand the weight of modern motors and dynamic loads at high speeds, and they use overhead sheets of the same duraluminum at least 4 mm thick to reinforce it.

The reinforcement process requires careful surface preparation, and the metal must be cleaned to shine, degreased, and then welded or riveted. ferro-welding preferably, as it provides a more durable and sealed seam, less susceptible to corrosion.

It's important not to overload the stern by shifting the center of gravity too far back, which can lead to a splurge on the boat and reduce stability, so all the additional structures in the stern should be as light as possible, but strong.

Special attention should be paid to the beams, the staff elements often deform when mooring, and the installation of an additional profile of stainless steel or reinforced aluminum corner will protect the board from impacts on the berth and other vessels.

Manufacture of comfortable flooring (floorboard)

Replacing the standard flooring is perhaps the most noticeable and pleasant part of the tuning. The new paiole must be not only lightweight but also rigid to eliminate vibrations. The optimal material is moisture-resistant plywood (PSF) with a thickness of 9-12 mm, covered with non-slip coating.

To make a good deck, you need to take the dimensions from the bottom of the boat with high precision. Plywood sheets are colored to take into account the gaps for water flow. Between the sheets and sides leave a compensation gap of 5-10 mm so that when the wood swells, the deck does not deform.

floorboard is not hard-wired, but is mounted with stops or rubber dampers, which quench vibration and prevent knocking, and the plywood surface is treated with olifu or special wood impregnation, and then coated with paint or carpeted.

Some owners go further and make flooring with built-in runducts. This requires more complex calculations and the use of lighter materials such as composite panels, but the result is worth it - there is additional sealed storage space.

Organizational places and rundooks

Lack of storage spaces – the main pain of owners OBE 1The solution is to install a nose knob, which is mounted in the bow of the boat and serves both as storage and as an additional buoyancy in the event of a rollover.

The harunduk is made with sheet aluminum, and it's a sealed box that fits into the geometry of the nose, and it's important to have a hatch to access the inside and a mounting system so that the box doesn't pop up when water hits the boat.

In addition to the nose, you can organize seats under the seats, and to do this, regular banks (seats) are replaced with higher structures with opening lids, and it is convenient to store fuel, remixes and personal belongings inside these cans.

Type Materials Volume (example) Difficulty of manufacture
nose-dump Aluminum D16AT 40-50 litres High.
Box jar Plywood + Aluminum 20-30 liters Medium
Suspension pocket Oxford fabric 5-10 liters Low.
Steering console Fiberglass 10-15 liters High.

When installing any elements, you must strictly monitor their fixation, and in the case of a boat capsizing, unsecured boxes can cause injury or loss of buoyancy.

Installation of transax wheels and additional equipment

Transche wheels are a must-have accessory for any boat, especially one as heavy as a boat. OBE 1They allow one person to easily pull a boat ashore and float it on the water. There are many blueprints for homemade wheels, but it's easier to buy a ready-made kit and adapt it to your transom.

The fastening of the wheels must be reliable and fast. Usually, they use rotary mechanisms that, when operating, are removed in the boat or along the side without disturbing the movement. It is important that the axis of the fastening passes through the reinforced part of the transom.

In addition to the wheels, you should think about installing a sonar and a navigator, and for this purpose, a hole is drilled in the bottom or transom under the sensor, which is necessarily sealed with special compounds, and the wiring is hidden under the skin or in special cable channels.

How to properly seal the holes in the bottom?

To seal the holes in the bottom, use two-component polyurethane sealants (such as 3M 4200 or analogs). Before applying thoroughly degrease the surface. Apply a sealant with a margin, forming a "puck" around the fastener. After installing the sensor, allow the sealant to dry for at least 24 hours before descending to the water. Do not use silicone - it does not hold well on aluminum and quickly breaks down from vibration.

Also popular is the installation of a windshield (console) that not only protects against oncoming airflow and splashes, but also allows you to fix navigation devices and a map in plain sight at the helmsman.

Painting and anti-corrosion protection

The final stage of tuning is painting. OBE 1 It's prone to oxidation, so surface preparation is critical, and old paint and oxides are removed by sandblasting or chemical washing.

The best painters are epoxy soils and polyurethane enamels, which create a durable, durable coating that is resistant to shock and ultraphyletics, and the color is chosen individually, but the lighter colors are less heated in the sun.

The interior of the boat, especially the seams and rivets, is recommended to be treated with a rust converter and coated with corrosion-resistant compound, which will prolong the life of the vessel for many years. Don't forget about the anodic protection if you plan to walk on salt water or water with an aggressive environment.

💡

When painting a boat, use high-quality paint tape to create clear boundaries between the colors. Remove the scotch immediately after the paint is dry to avoid damaging the edge.

Regular care of the coating, including washing and applying protective polishes, will preserve the appearance of your Obi. Remember, even the best paint doesn't stay on a dirty or greasy surface.

Final cost and efficiency assessment of improvements

Tuning boats OBE 1 It's an investment that pays off in comfort and safety, and the cost of materials can vary depending on the solutions you choose, from low-cost plywood to expensive fiberglass and stainless steel.

But even the minimal investment of quality decking and sling wheels changes the boat's perception, and you stop struggling with the inconvenience and start enjoying the process.

💡

The main principle of tuning Ob 1: do not strive to make a racing car, but create a reliable, dry and quiet fishing tool, while maintaining ease of maintenance.

In conclusion, any refinement requires responsibility: Check each connection, test the boat in shallow water before long exits, and don't neglect safety rules. OBE 1 Ready for new things!

Do I need to register a tuning boat in GIMS?

If the changes do not affect the main specifications (load capacity, passenger capacity, engine power) and do not change the design of the body, then registration of changes is not required. However, when installing a powerful engine or changing the type of engine (from PM to stationary), changes in the documents are mandatory.

Which glue is better to use for gluing linoleum to floorboard?

To stick linoleum or carpet on plywood floorboard, it is best to use polyurethane adhesives or special adhesives for PVC. They are elastic, not afraid of water and temperature changes. Avoid water-based adhesives, as they can cause plywood to rot.

Can I put on the Ob 1 engine with a capacity of 30 hp?

The factory recommendation for Ob 1 is up to 15-20 hp Installation of a 30-horsepower engine is possible, but requires serious strengthening of the transom and change of alignment. This can be dangerous and illegal without appropriate certification.
