Beginners often face terminology confusion when choosing their first swimmer. The word cockpit is often used in descriptions of polyvinyl chloride models, but not everyone understands its exact meaning in the context of inflatable designs. In classic shipbuilding, this term refers to the deepened part of the deck, protected by the sides from being swept by waves, where the steering or rowers usually sit.
In peace. PVC Now, the concept has evolved, and now more often means a specific floor design that provides stiffness and protection, and it's not just a bottom, but a complex system of inflatable tubes and rigid flooring that turns a soft pancake into a full-fledged vessel that can hold the wave and withstand the weight of a powerful motor. Understanding this part of the hull is critical to the right equipment selection.
The type of bottom and cockpit you choose will not only affect the comfort of your walk, but also the safety of the entire crew on the water. The wrong floor can cause instability or premature wear and tear, and let's look at what's hidden under this term in manufacturers' catalogs and what's really worth paying attention to when buying.
Evolution of the concept: from sea vessels to inflatable structures
Historically, the term came from sailing and motor fleets, where cockpit The main purpose of this structure was to prevent the entry of seawater into the vessel when rolling or turbulent, and the water that got in simply flowed back into the sea through special scuppers without interfering with the crew.
In construction PVC-boat So engineers adapted this by creating a system of inflatable tubes that form a pocket for the legs or the cargo bay, and unlike a rigid hull, air chambers act as bulkheads, and decks function as inflatable stringers or hard floorboard sheets, which allowed them to maintain the ease of transportation inherent in in inflatable products and add the seaworthiness of large boats.
Modern. cockpit It's basically a protected area, with spaced cylinders that have a deck strung between them or a hard floor, and it's a structure that allows you to effectively dissect the wave and keep passengers dry even when you're driving against the wind, and it's a fundamental difference from flat-bottomed models, where the sides are level with the bottom.
⚠️ Note: Do not confuse a structural cockpit with the simple presence of an inflatable floor (BBB). cockpit implies the presence of pronounced onboard cylinders that protect the central part, whereas NDB is only a type of decking that can be found on boats without a pronounced cockpit.
Design features and types of flooring
The backbone of any cockpit in an inflatable boat is a form support system. Without a rigid or semi-rigid element, the soft sides will simply disperse under load. Manufacturers use several types of solutions, each with its own advantages and disadvantages in operation, depending on whether you plan to go for an outboard motor or prefer rowing.
The most common option is to use plywood or aluminum floorboards, which are stacked on cockpit inflatable tubes and fixed in slots, creating a monolithic platform. Hard floor. It allows you to stand on your feet, move around the boat and install heavy attachments without the risk of damaging the bottom.
The alternative is a low-pressure inflatable floor (LDPB), which is also part of the cockpit system, and in this case, the rigidity is provided by thousands of internal strands that keep the balloon from stretching out wide, which is built faster, but requires more careful handling of stabbing objects and is less resistant to heels or sharp corners of drawers.
- 🛶 Slate floor: individual slats inserted into pockets at the bottom are suitable for small rowing boats.
- 📦 Plywood plywood: solid hard flooring, providing maximum stability and protection from waves.
- 🎈 NDNDM: high pressure inflatable floor, quick assembly, but less resistance to punctures.
Importantly, the quality of the cockpit is directly dependent on the material of the cylinders, and typically you use a five-layer PVC reinforced fabric that is resistant to gasoline, oil and ultraviolet, and the strength of these cylinders determines how long your boat will last in active operation on rocky shores or overgrown seaweeds.
Advantages of boats with a pronounced cockpit system
The main advantage of having a full cockpit is high seaworthinessThe high-sided, hard-bottom design is better at steering, less susceptible to wind demolition, and allows higher speeds without the risk of loss of controllability. Water does not spill overboard, remaining outside of usable space.
The second important advantage is comfort and safety, and when you're inside a protected cockpit, you feel more secure, and when you're inside a hard floor, you can stand up to the full height for spinning or looking at the terrain, which is not possible in soft-bottom boats, and it's also better at protecting you from cold splashes, which is important in the spring and fall seasons.
The third aspect is load capacity and weight distribution, and a properly designed cockpit allows passengers and cargo to be positioned to make the boat's differentiation optimal, reduces the risk of tipping over and improves driving performance for an outboard motor, and you can bring more gear with you without fear that the boat will sit too low.
When choosing a boat with a cockpit, pay attention to the height of the cylinder. For open water, the optimal height is considered to be from 35-40 cm and above, which will ensure dryness even with moderate chop.
Disadvantages and limitations of operation
Despite the obvious advantages, boats with a massive cockpit and hard floorboard have their drawbacks, primarily weight and dimensions assembled. Plywood sheets and heavy cylinders can weigh tens of kilograms, making it difficult to transport alone. You will need a reliable trunk on a car or trailer.
The build and disassembly time is also extended, and if the inflatable floor can be pumped in 5-10 minutes, it will take 20-30 minutes to lay the solder floor and install the stringers, especially for the inexperienced user, and in cold weather or high winds, this process can turn into a test that requires patience and physical strength.
Another nuance is the storage requirement: rigid floor elements do not like moisture and temperature changes, they can dissipate or deform if stored improperly in winter. inflatable tubes They also need periodic pressure checks and protection from rodents that often attack garages and balconies.
⚠️ Warning: Never leave a fully assembled cockpit boat in direct sunlight for long periods of time. The air pressure inside the cylinders rises when heated, which can cause the seams to rupture or deform the hard floorboard.
specifications comparison table
For ease of choice, let’s look at the main differences between design types in the comparative table, which will help you navigate the range faster and discard the wrong options.
| Characterization | A boat with a floorboard cockpit | Boat with NDM | Rowing boat (sleigh) |
|---|---|---|---|
| Packaging weight | Tall (30-60 kg) | Medium (20-40 kg) | Low (10-20 kg) |
| Assembly time | 20-40 minutes. | 10-15 minutes. | 5-10 minutes |
| Seaworthiness | High. | Medium/High | Low. |
| Comfort standing up | maximum | Good. | Missing. |
As you can see from the table, boats with classic hard cockpits win in comfort and seaworthiness, but lose in mobility. If you plan long-distance outings on large water with an overnight stay, this choice is justified. For frequent trips “for an hour” from shore closer to home, you should look at models with NDNDL.
☑️ Checking the cockpit's readiness for the season
Features of selection for different tasks
The choice of cockpit configuration should be based on use cases. For fishing from shore, where the boat must be dragged along the thickets often or dragged with a drag, the heavy solder variant can be a burden. NDMA Or even a rowing model that can be quickly lowered into the water.
For trolling or running fishing in large reservoirs, where platform stability and the ability to install multiple fishing rods are important, a hard-floored cockpit is a no-choice option. It allows you to securely securely secure the sonar, navigator and rod holders without fear that they will fall overboard when the wave passes.
Family vacations and tourism also dictate their demands: Having children on board requires the maximum safety that only a high board and a hard bottom can provide. In such a boat, a child can sit on the floor without risking falling over the low board, and parents can be reassured for the stability of the vessel.
The Secret to Longevity of the Cockpit
To extend the life of an inflatable cockpit, always use a mat when you're lowering the boat onto sand or pebbles. Microscopic scratches from the rocks eventually turn into scuffs that reduce the strength of the fabric. It's also helpful to have a remix and glue on hand, even if you're not planning on repairing in the field.
Care and maintenance of the inflatable cockpit
The durability of your boat depends on how you care for it. After each foray into the water, you need to thoroughly wash the cockpit with fresh water, removing sand, silt and fish residues. Salt and organics aggressively affect adhesive seams and PVC tissue, gradually destroying their structure.
Drying is a critical step. You can't put a wet boat in a case, because it will lead to mold and bad smell, which you can't get rid of later. Dry the product is needed in the shade, in a straightened form, so that moisture evaporates from all folds and seams.
Check the pressure in the cockpit cylinders regularly before each operation. A sub-pumped boat is more vulnerable to damage and behaves worse on the water, and a pumped in the heat can burst. Use a pressure gauge to fine-tune it, especially if the temperature changes during the day.
⚠️ Attention: To clean PVC, you should not use solvents, acetone, chlorine-containing agents and abrasive sponges. Use only soap solution and soft tissue so as not to damage the protective layer of tissue.
Proper care of the cockpit increases the life of the boat by 2-3 times, maintaining its tightness and appearance for many years.
Frequently Asked Questions (FAQ)
Can I install a cockpit from one boat model to another?
Normally not. The design of the cylinders, the location of the stringers and the shape of the floorboard are unique to each model and manufacturer. Trying to install someone else's cockpit can disrupt the geometry of the boat, which will lead to loss of sealed seams or instability on the water. The exception is universal inflatable floors, but they rarely fit perfectly.
What is the minimum size of the boat that makes you feel comfortable in the cockpit?
Comfort starts with a length of 320-340 cm Models shorter than 3 meters (for example, 280 cm) also have a cockpit design, but the space inside will be limited. For one person with a load is enough 320 cm, for two with a motor and equipment, it is better to consider options from 360 cm and above.
Do I need to lubricate the valves in the cockpit?
You can't oil the valves themselves with oil or fat, it'll damage the rubber seals, but you can gently wipe the threaded part with silicone lubrication so it can be easily twisted and not jammed, and the main thing is to avoid getting the chemistry onto the PVC fabric.
What if the floorboard in the cockpit started to creak?
Screaming occurs because plywood frictions against fabric or metal elements, and you can put a special tape between the layers of floorboard or between the floorboard and the balloon (for example, fume tape or strips of fabric), and treating the ends of the plywood with paraffin or wax also helps.
Will the cockpit of PVC withstand wintering in the cold?
Modern PVC materials are resistant to low temperatures, but they become brittle. You can store the boat at sub-zero temperatures, but it is strictly forbidden to bend, fold or move it in this state. Before assembly, the boat must warm up to room temperature for 10-12 hours.
