Aluminum catamarans are deservedly considered the kings of domestic reservoirs, and the model is Riviera 3400 This project was a response to the demands of fishermen and hunters who needed not just a boat, but a full floating platform with high seaworthiness, and the design is characterized by strength, wave holding and stability that monohulas of similar size do not have.
The secret to popularity lies in the clever combination of dimensions and weight, which, at just over three meters in length, remains light enough to transport on a standard trailer, but still accommodates a crew of four with a full set of equipment. load-carrying capacity and maneuverability in shallow water conditions.
The development was designed to meet the harsh realities of exploitation in Siberia and the Far East, so the focus was on maintainability and simplicity of design. If you're looking for a reliable tool for work and recreation on the water that will last for decades with minimal maintenance, then you're looking for a reliable tool for working and resting on the water. Riviera 3400 This is the number one candidate to consider.
Design features and geometry of the body
The design is based on a catamaran with two parallel cylinders, and this geometry provides phenomenal stability even when anglers move abruptly across the deck. AMG5 or AMG6The thickness of the sheets varies from 3 to 4 mm, which allows the body to withstand impacts on ice or stones without critical damage.
And between the cylinders is a deck, which is the main workspace, and it's raised above the water, which makes it dry even in high waves, and an important piece of equipment is a transom, which is reinforced by additional bulkheads, and it allows you to install motors up to 30 hp, making the boat a fast boat.
⚠️ Attention, in shallow waters, you don't have to rely on the thickness of the metal, and aluminum, while strong, can get a hole in the area of the balloon when it hits a snag hidden under water at high speed.
The sealing system deserves special attention, all the seams are argon-arc welding, which makes the body monolithic. Unlike riveted structures, there is no risk of leaking through rivets in the future.
Body welding technology
The Riviera 3400 body is welded in an inert argon gas environment, which prevents the oxidation of aluminum in the seam zone, using a filler wire of the appropriate brand (usually Sv-AMg61 or analog), which provides a strength of the seam that is not inferior to the base metal. Violation of welding modes (too high current or speed) can lead to burning or porosity of the seam.
Technical specifications and weight parameters
For the potential owner, the numbers are crucial when choosing a vehicle and trailer. Riviera 3400 has the following data-sheet figures, which may vary slightly depending on the year of manufacture and configuration, an understanding of these parameters is necessary for the correct calculation. load capacity and the choice of engine.
| Parameter | Meaning | Note |
|---|---|---|
| Maximum length | 3.40m | By the cylinders. |
| maximum width | 1.85 m | Excluding bulk |
| Height of board | 0.45m | From deck to coamings |
| Body weight (b/m) | 110-120 kg | Depends on the thickness of the metal. |
| Load capacity | 450 kg | Including passengers and equipment |
The 115kg weight of the boat allows it to be loaded into the back of a pickup truck or onto the roof of an SUV with two people without the use of a winch, a significant advantage over heavier steel counterparts, but when additional equipment such as haunches, anchor boxes and powerful batteries are installed, the weight can increase, which requires a recalculation of the alignment.
Engine compartment and power recommendations
Rear side Riviera 3400 designed with outboard motors. the design of the transom withstands the loads of engines up to 30 hp, although the optimal range for economical and comfortable operation is considered 15-25 hp Installation of a more powerful motor is possible, but requires caution due to the risk of exceeding the risk of excess passport-speed and loss of control.
When choosing a motor, you should consider not only the power, but also the length of the lower unit. For this model, the standard lower unit (S) is optimal, since the long (L) can create excessive resistance or, conversely, too deep in the course along the wave.
⚠️ Attention! Never exceed the maximum recommended engine power specified in the data sheet. This can lead to the collapse of the transom, the tipping of the boat due to sharp aft trim and injuries to the crew.
Owners often report good plane sliding even with two passengers, and to get on plane mode, you need a 15 hp engine with a properly selected screw. anticavitational plate, which protects the screw from air capture and provides a stable support.
When installing the motor on the Riviera 3400, use the safety cable for PM. Run it through the fry bolt on the transom and fix the engine on the lower unit so that in case of breakage the engine does not sink.
Ergonomics of the deck and layout options
The deck space is the main fishing area. Riviera 3400 It's a flat area, giving the owner complete freedom to organize the interior space, so you can install the knobs, seats and gear mounts yourself, adapting the boat to your needs.
Most often, owners choose one of three layout schemes:
- 🎣 Fishing: installation of two transom cans with boxes for tackle and chairs for spinning fishing.
- ⛺ Tourist: Placement of an inflatable awning and sleeping places for overnight stay on the water.
- 🚤 Transport: Minimalism, maximum free space for transportation of goods and dogs.
For ease of movement on the deck, special non-slip mats made of foamed PVC or EVA materials are often used, they not only prevent slipping in wet shoes, but also perform the function of thermal insulation, which is critical in the cold season. pillboxes in the bow for storing anchor and falt.

Tuning and modernization DIY
The aluminum case is perfectly modernized, unlike plastic, in the sides. Riviera 3400 You can drill holes to install additional equipment without the risk of damage to the integrity of the structure, if you follow the technology. console with windshield.
The console allows for ergonomic placement of the dashboard, steering and navigational instruments, and for its installation, you need to strengthen the deck at the mounting point by welding or attaching additional aluminum plates to the sealant, which will distribute the load and prevent vibration.
Another popular element of tuning is the installation of perimeter inflatable tubes (bulk), which serve a dual function: increase the usable area of the deck and serve as an additional security tool, increasing unsinkability, and soft sides protect the hull from impacts on the berth or on the side of another boat.
The most effective tuning for the Riviera 3400 is the installation of wind protection and soft inflatable sides, which turns a utilitarian boat into a comfortable boat for the family.
Maintenance and durability of aluminum
Term of service The 3400 Riviera is virtually unlimited when properly maintained, and aluminum does not rust like steel, but is subject to electrochemical corrosion when in contact with other metals in salt water. zinc protectorsIf you operate a boat in sea waters or in waters with high mineralization.
After each fishing, it is recommended to wash the salt and dirt with fresh water. Pay special attention to the engine attachment and the transom. If you notice white oxides on the seams, they should be cleaned with a soft brush and treated with a special composition to protect aluminum. It is better to keep the boat upside down or on a special slipway to ensure ventilation of the inner surface.
Once a season, check the condition of welds and fixtures of interior elements. Vibration during the course at high speeds can weaken the bolt joints of runduks and cans. Timely stretching of threaded joints will save you from problems in the middle of the reservoir.
How to wash an aluminum boat properly?
Use only neutral detergents. Acid or alkaline formulations can damage the oxide film on the aluminum surface, leading to metal tarnishing and accelerated corrosion. Use special polyroles for aluminum to remove oxides.
Can I paint the Riviera 3400?
Yes, but it requires special training, aluminium needs to be cleaned, degreased and coated with non-ferrous metals (such as zinc-based) and conventional paint without soil will not last long.
What is the real speed with a 20 hp engine?
With one driver and a minimum load, the Riviera 3400 with a 20 hp engine develops a speed of about 25-28 km / h With a full load, the speed drops to 18-20 km / h, which is normal for a catamaran type body.
Do I need to register a boat with GIMS?
Registration depends on the mass of the boat in gear and the power of the engine. If the weight of the boat (115 kg) plus the mass of the engine (for example, 45 kg) exceeds 200 kg, or the power of the engine exceeds 8 hp (8 kW), registration is required.
What is the difference between the Riviera and the Kazanka boats?
The main difference is in the hull scheme: Kazanka is a monohol (one body), which is strong on the wave and has less stability. Riviera 3400 is a catamaran that is almost non-reclining, has a larger deck area and better holds the wave, but can be slightly heavier than similar in length monohols.
