Planning a fishing trip or a water trip often starts with a simple logistics issue, rather than a route, and many owners of watercraft have to think about how to get their boat to the water, especially if you can not use a trailer or garage next to the reservoir, which is why the question of how much weight an inflatable boat weighs when folded becomes critical for outdoor activities.
Weight. PVC boats It can have a huge impact on whether you can bring it to shore alone, whether it fits in the trunk of a car, and how comfortable you feel when you're carrying gear. The mass range can be enormous, from lightweight singles to heavy multi-seats that can withstand a powerful engine.
In this article, we will discuss in detail what the mass of an inflatable vessel is made of, how the density of the material and design features affect the final figures, you will get accurate data for planning transportation and understand what exactly you should pay attention to when choosing a model for specific operating conditions.
Factors affecting the weight of an inflatable vessel
The main factor determining weight is, of course, the density and thickness of the material used. polyvinyl chloride (PVC) is of different densities, usually from 750 to 1100 g / sq.m. Boats made of denser material, for example, 1100 g / sq.m., will be much heavier than their counterparts of 850 g / sq.m., but at the same time have better puncture resistance and durability.
The second important aspect is the design of the bottom: a simple inflatable floor (ND) adds a minimum of weight, while a plywood or aluminum alloy plywood bottom significantly weights the structure when disassembled. The presence of rigid transverses, high-pressure inflatable tubes and additional reinforced elements also contributes to the total mass.
And the hardware, metal liner rings, rod holders, and valves are all made of metal or strong plastic, which adds up to a tangible addition. For larger models, the weight difference between the base and the luxury version with additional equipment can be as high as 15-20%.
⚠️ Attention: When calculating weight, always consider the weight of the package. Boat bags are often sewn from a dense tarpaulin with metal fittings, which can add another 1-3 kg to the total weight you will have to drag.
Weight is also affected by the number of compartments and bulkheads inside the cylinders, and the more independent chambers, the more seams and valves are used in manufacturing, which inevitably leads to an increase in the weight of the product, a necessary trade-off for safety on water.
Classification of boats by weight and dimensions
All inflatable boats can be divided into several weight categories, each designed for specific tasks, and light single models are often called “rowing” because they are designed primarily for the use of oars, although they allow the installation of a low-power engine.
The middle class are versatile boats for 2-3 people. They already have a full-fledged transom for the engine and often have a hard or inflatable floor. It is in this category that the most common dilemma is between ease of transportation and comfort on the water. Heavy models are full-fledged motorboats, often with low-pressure inflatable floor (LDPT), which weigh as much as small metal boats.
The specialty vessels, such as rafts for alloying or diving boats, can be reinforced with additional layers of fabric and protective elements, making them the heaviest in their class, and the choice of a particular category should be based not only on the number of passengers, but also on the physical capabilities of the crew to carry the cargo.
Weight of popular models depending on length
To give you a concrete idea of the numbers, consider the weight-to-body length ratio, which is the most important parameter that immediately cuts off the inappropriate options. Below is a table with averaged data for popular models without taking into account the weight of the engine and equipment.
| Boat length (m) | Type of bottom | Approximate weight (kg) | Capacity (person) |
|---|---|---|---|
| 2.0 - 2.4 | Inflatable/Plywood | 14 - 22 | 1-2 |
| 2.7 - 2.9 | Plywood plywood | 28 - 36 | 2-3 |
| 3.0 - 3.2 | Plywood/Aluminum | 38 - 48 | 3 |
| 3.5 - 3.8 | NDNDM/Pyol | 50 - 65 | 3-4 |
| 4.0+ | NDMA | 70 - 90+ | 4-5 |
As you can see from the table, as the length increases, the weight increases exponentially, not linearly. A 3.2-meter boat can be too heavy for one person to carry comfortably, especially if the bags do not have a convenient weight distribution system. Models over 3.5 meters almost always require a car in close proximity to the descent.
It is important to note that the weight in the table is for the basic configuration: adding keel protection, anchor box or a second transom under the second engine can increase the weight by several kilograms. Always check the weight of a particular modification with the manufacturer before buying.
Effect of the material and design of the bottom on the mass
The design of the bottom is perhaps the most powerful argument in the dispute over the weight of the boat: the classic solution with rigid floorboards (sections of the floor) of waterproof plywood provides excellent cruising, but makes you carry heavy slabs. The weight of one set of floorboards for a boat of 3.2 meters can be 10-12 kg.
The alternative is aluminum profiles, which are lighter and more durable than plywood, but still add substantial weight. NDMA These boats, when folded, weigh significantly less than their hard-floor counterparts, because heavy slabs are replaced by an inflatable membrane.
Why is NDNDM easier?
The secret is that there are no hard elements, instead of plywood or aluminum, a double membrane with vertical strands and heavyweights is used, which reduces the weight of the boat by 30-40% compared to the soldering counterparts of the same length, which is critical for transport in the trunk of a small car.
But the inflatable floor has its own specifications: it requires more careful drying before packaging, otherwise mold can form inside, which is not only unpleasant, but also adds weight due to the absorbed moisture, and the bottom fabric in these models is often thicker and stronger, which partially compensates for the gain in mass.
Transportation: boat, motor and equipment
When we talk about how much an inflatable boat weighs when folded, we must not forget about the engine: a 5 hp petrol two-stroke engine weighs about 20-22 kg, and 9.8 hp already weighs all 26-28 kg. Electric motors can be lighter, but a heavy lead-acid traction battery will add another 15-20 kg to your load.
Equipment is the hidden enemy of easy transportation. Anchor, life jackets, sonar, fuel tank, oars, pump, all of these have to be placed somewhere. In total, a full-length fishing kit easily adds another 15-25 kg to the weight of the boat itself. So when you choose a boat, always count the total weight you have to load into and unload from the car.
☑️ Pre-purchase check
To make transportation easier, manufacturers often pack large boats with wheeled bags, which are great for flat roads and parking, but on a sandy beach or steep slope to the water, such bags can become useless, in which cases the ability to divide the cargo helps: take out the floorboard separately or carry the boat bag and the motor bag separately.
Comparison: PVC vs. rubber and aluminum
To make the picture complete, it is worth comparing inflatable PVC boats with their closest competitors. inflatable boats, popular in the past, are much lighter than PVC counterparts of the same carrying capacity, but they are inferior in strength and durability. Ufimka or Orc.) is still relevant.
Aluminum boats (Kazanki) benefit in speed and durability, but lose in logistics. They can not be folded into a bag, they require a trailer or permanent storage on the water. The weight of an aluminum boat 3 meters long can start from 60-70 kg in empty condition, making it a stationary solution.
⚠️ Attention: Don’t try to pack a wet boat right after the water. The soaked cloth of water can add up to 3-5 kg of excess weight, and storing it in this form is guaranteed to lead to fungus and an unpleasant smell that is difficult to get rid of.
So PVC remains the middle ground, offering a balance between strength, comfort and transportability, and modern materials allow boats that weigh slightly more rubber, but have specifications similar to rigid hulls.
Tips for selection and operation
When choosing a boat, be guided not only by specifications, but also by real-world conditions. If you don't have assistants and plan to fish alone, it may be worth sacrificing space for weight loss. A boat of 2.9 meters is often the optimal limit for one person.
Pay attention to the quality of the seams and valves. A light boat should not be "disposable." Using high-quality glue and reinforced fabric allows you to reduce weight without losing reliability. Cheap analogues can weigh less due to savings on materials, but this is a risky savings.
Use vacuum bags to pack clothes and soft gear inside the boat bag. This will not only save space, but also protect things from moisture if the boat is not completely dry.
Regularly check the pressure in the cylinders. Under-pumped boat loses its driving performance and wears out faster, and pumped in the sun can become dangerous. Proper maintenance prolongs the life of the material, maintaining its original properties and weight.
The optimal weight of the boat for one person in full assembly (with engine and equipment) should not exceed 40-50 kg for comfortable transportation without special tools.
Frequently Asked Questions (FAQ)
Can you reduce the weight of the boat by yourself?
In theory, you can replace plywood paioles with lighter materials, like cellular polypropylene or aluminum, but it requires skill and can disrupt bottom geometry. You can also remove excess fittings if you don't use them, but it rarely has a significant effect.
Does the weight of the boat increase in winter?
Yes, in winter, weight can increase due to freezing and snow falling into the folds, and the cold air inside the cylinders shrinks and the boat becomes less rigid, which requires pumping. Always clear the boat of snow before packing.
How much weight can a standard inflatable boat withstand?
The capacity depends on the volume of cylinders. Usually, for one person and equipment, 150-180 kg of stock are counted. A boat 3.2 meters long usually has a full carrying capacity of about 450-500 kg, including the weight of the boat itself, the engine, people and cargo.
Does the color of the boat affect its weight?
Color does not directly affect weight, as dyes are added in minimal quantities, but camouflage boats are sometimes made of denser material for camouflage and protection, which can indirectly increase their mass.
