Choosing a reliable boat for fishing or family vacations on the water often leads to the consideration of models of the middle size range. PVC Inzer 330UIt's a classic flat-bottom design designed to be able to navigate rivers, lakes and reservoirs in a calm, moderate wave.
The main feature of this model is the combination of affordable prices and time-tested design with inflatable tubes. 330U Insert It is positioned as a universal solution for anglers who care about load capacity and stability on the water, rather than high speed plane specifications. In this review, we will discuss in detail the technical nuances, features of assembly and real capabilities of this craft.
It should be noted that the model belongs to the class of rowing boats with the possibility of installing an outboard motor, but its geometry dictates its own rules of operation, which every potential owner should know. inflatable tubes provide excellent buoyancy, but require careful attention to the pressure and integrity of the seams during operation.
Design features and materials
The basis of durability of any inflatable boat is the material from which it is made. 330U Insert It uses a five-layer reinforced PVC fabric that is highly resistant to mechanical damage and ultraviolet light, with a material density of 750 g/sq.m, which is standard for economy boats, providing the necessary margin of safety at moderate weight.
The cylinders are designed in a classic way: two main inflatable sides and an inflatable transom seat, which is also aft, and this scheme maximizes the useful space of the cockpit. Stitches made by gluing on the floor using two-component polyurethane glue, which guarantees the tightness of the connection while observing the temperature regime of operation.
Technical details of seams
The seams in the Inzer 330U model are glued with ribbons 4-5 cm wide, this creates an additional buffer layer that protects against tissue stratification during sharp temperature changes or prolonged exposure to load.
An important element of safety is the availability of keel Or just a reinforced bottom (depending on the year of release and modification), which takes the main blows to the bottom. However, it is worth remembering that this is not a full-fledged keelson, but rather abrasion protection. For additional protection, it is recommended to use special mats or linoleum for frequent landings.
- 🛡️ Reinforced PVC density of 750 g / sq.m. provides resistance to punctures.
- ⚓ The reinforced carry handles are glued on the nose and stern.
- 🔒 The reliable valve "Frog" allows you to quickly blow air.
- 🎣 Two timbers around the perimeter serve to fasten the tooling.
Hard sex system (floorboard)
The key difference between the model with the index "U" (or often marked as a complete set with a floor) is the presence of a rigid deck. 330U Insert It uses a waterproof plywood floorboard system, which changes the experience of being in a boat compared to an inflatable floor, and it gives you a flat surface that you can walk on with confidence, and you can install a more powerful motor.
Building the floor takes time and effort, and the plywood sheets are connected by aluminum stringer profiles that are inserted into the grooves. Aluminum profile It runs along the bottom, giving the structure the necessary rigidity and preventing plywood from bending under the weight of passengers, so it is important to make sure that the profiles are inserted to the point, otherwise the floor will "walk".
Lubricate aluminum stringers with silicone lubrication before assembly – this will facilitate the installation process and protect the metal from oxidation in salt water.
The plywood used in the kit is usually 9 mm thick, a trade-off between weight and strength, and when properly operated, it lasts for years, but is afraid of prolonged contact with water. plywood You need to extract, wipe and dry to avoid stratification and loss of geometry.
⚠️ Warning: Never leave plywood floors in a assembled boat for long periods of storage, and the humidity inside the cylinders will cause the wood to swell and mold to appear, which will damage the PVC fabric from the inside.
Dimension, weight and load capacity
Boat size 330U Insert It's the best car to carry in the trunk of a mid-range car, and when disassembled, it takes up space comparable to two large backpacks, but the weight in the assembled state may come as a surprise to those who plan to carry the boat alone over long distances.
The model’s load capacity allows for comfortable accommodation of two adults with a full suite of fishing gear. rated carrying capacity is usually around 350-400 kg, but the actual payload, taking into account the weight of the boat and the engine itself, will be less. WorkloadThe boat behaves predictably and has a good buoyancy reserve, which is about 200-250 kg.
| Parameter | Meaning | Note |
|---|---|---|
| Full length | 330 cm | With transom in mind |
| Full width | 145 cm | On the outer cylinders |
| Diameter of the cylinder | 36 cm | Standard for class |
| Weight of kit | ~38 kg | With plywood floors |
| Passenger capacity | 2 people. | Recommended |
It should be noted that these dimensions are relevant for the inflated state. In the deflated form, the dimensions are much smaller, but the weight remains the same. kit It can be a difficult task, so it is recommended to break the load into pieces or use a trolley.
Engine operation
Although 330U Insert Often considered as a rowing model, the presence of a transomboard allows you to install an outboard motor. Tram is made of moisture-resistant plywood reinforced with linings, and can withstand engines up to 3-5 hp However, the geometry of a flat-bottomed boat imposes serious restrictions on speed modes.
One-person planing is possible with a motor of 3.5 hp and above. With two passengers on board, the boat goes into displacement mode and moves at a speed of about 5-7 km / h, regardless of the engine power. Flat bottom It creates a lot of water resistance, which makes the use of powerful motors economically and technically impractical.
When installing the motor, it is critically important to set up correctly transom-angleBecause the boat is light and has a low depth, improper installation of the lower unit will lead to "goose" - jumps of the nose, which is dangerous for passengers. The optimal speed for safe movement on this model does not exceed 15-18 km / h.
- ⛓️ Use the safety cable for the motor, fastening it to the rims on the nose.
- 🔋 For engines 2-3 hp, light two-stroke models are ideal.
- 🌊 Avoid driving above 0.5 meters when driving for an outboard motor.
- 🛢️ Always have a fuel reserve with a rate of 30% more than the planned route.
⚠️ Warning: Exceeding the recommended power of the engine (more than 5 hp) can lead to the destruction of the transom board and the overturning of the boat due to a sharp rise of the bow.
The process of assembly and preparation for water
Assembly 330U Insert This is a process that requires a certain skill, especially in terms of flooring. The first step is always to lay the boat on a flat surface and remove debris. Then pump the cylinders to the working pressure, which is usually 0.2 atm (controlled by pressing a finger - the balloon must be slashed by 1-1.5 cm).
Once the cylinders are pumped, the most time-consuming phase is the laying of the floorboards, and the plywood sheets are laid out inside the cockpit, and then the stringers are inserted, and this process requires physical effort, because the profiles must be tightly entered. The final step is the pumping. air-seat and check all the connections.
☑️ Ready to launch
There's an important aspect of temperature and air temperature, which is that if you pump a boat in a warm room and you lower it into cold water, the pressure inside the cylinders will drop, and vice versa, if you leave a boat in the sun, you can get too much pressure. Pressure control A mandatory procedure before each release to the water.
Proper assembly sequence (first cylinders, then floor) reduces preparation time by 30% and reduces the risk of damage to PVC tissue by sharp plywood angles.
Care, storage and repair
Durability of the boat 330U Insert The PVC material is afraid of direct sunlight when exposed to long-term exposure, so you can not store the assembled boat under ultraviolet light. The ideal place is a dry, dark garage or a storeroom at a temperature of +5 to +25 degrees Celsius.
After each operation, especially in salt water or bodies of water with blooming water, the boat must be washed with fresh water and thoroughly dried. Wet fabric is the ideal environment for the development of fungus that destroys the reinforcing layer. transom board And the floorboards are dried separately from the cylinders in a vertical position.
In the case of a puncture, the repair is done with a remix that comes with the kit, and the surface is cleaned, degreased and sealed with a patch of the same PVC fabric using a special glue, and it is important to let the glue polymerize according to the instructions without forcing the process by heating.
How to keep a boat in the winter?
Winter storage requires drying all elements completely. The boat is recommended to be slightly pumped (up to 0.05 atm) to avoid sticking the inner walls, and hung horizontally or placed on shelves. You can not put heavy objects on the boat that can deform seams at low temperatures when PVC becomes less elastic.
Can I repair the boat by myself?
Small punctures and cuts up to 5-7 cm long are quite repairable at home, however, if the damage is due to a seam or has a complex geometry, it is better to contact a specialized workshop. Incorrect adhesive of the seam can lead to depressurization of the balloon under water load.
Which glue is best used for PVC?
For boat repairs Insert Two-component polyurethane adhesives (e.g. Texacol or specialized adhesives from the manufacturer) are used to provide an elastic and water-resistant seam. The use of household adhesives such as Moment or Cyanacrylate (Superglue) is unacceptable, as they make the material tough and brittle.
Why does the boat lose pressure in the cold?
This is a physical property of gases (Gay-Lussac's law): when you lower the temperature, the pressure in the closed volume drops. It's not a defect or a leak. When you go out of a warm garage, the pressure drops in the cold, and the cylinders become soft, and you have to pump them on the shore before you go down.
How long has the Inzer 330U been in service?
With careful operation, indoor storage and timely maintenance, the lifespan is 7-10 years or more. The main factor of aging is ultraviolet light and mechanical damage. Regular treatment of tissue with protective compounds (UV sprays) helps to extend the life of the material.
