When choosing a PVC swimmer, many beginners come across incomprehensible terms that dramatically affect comfort and safety. cockpitUnlike metal boats, where it's just space in the stern, in inflatable vessels, the term is often confused with the type of floor or transom design. Understanding this difference is necessary for the right equipment selection.
In the context of inflatable boats cockpit often implies the presence of self-moulded It's a sophisticated engineering system that allows water to be automatically removed from the interior of the vessel through special valves located in the bottom, and it turns an inflatable boat into a full-fledged water tank. toolIt is capable of withstanding strong waves and water discharges without the risk of flooding.
But don't think that the cockpit is the panacea for all evil. technical limitations And the care features that manufacturers sometimes don't mention, and if you're planning to go fishing or going for a walk in big water, you need to understand the mechanics of the drainage system in detail so you don't have to face unpleasant surprises on the water.
Constructive features of the self-dimming sex
The basis of the design is a double bottom, made of durable reinforced material PVC or HypalonThere are special layers of tissue. strutting Or tissue compounds that hold the shape of the floor under pressure and keep it from collapsing when it's inflated, and it's this rigid structure that allows the boat to keep its shape even when it's rolling heavily.
At the bottom of the bottom, at the lowest point, are installed discharge valveThey vary from one to three depending on the length of the vessel and the expected load. The principle of operation is simple: when the boat is afloat, the water level is higher outside, and the valves are closed under water pressure or special plugs. Once the liquid accumulates inside, the pressure inside exceeds the external (or a mechanical plug opens), and the water flows overboard.
⚠️ Warning: When operating a cockpit boat in shallow water or when mooring near a gentle shore, always block the drain valves. Otherwise, the water will not go from the boat, but into it, which can lead to a quick exit. flooding interior space.
And it's important to note that the floor in these models is always above the waterline. centreThe boat's passengers are sitting "upstairs," which is easy to see, but requires careful handling of sudden movements, and the rigidity of the floor allows them to stand on their feet, which is critical for spinning.
Key Benefits of Cockpit Boats
The main argument in favor of buying a model with a self-defeating floor is securityIn extreme conditions, when the wave is constantly flooding the boards, a flat-bottomed boat will quickly gain water, you will either have to work constantly scooping or risk tipping over. water-flowerIt allows you to focus on fishing or fishing.
The second important advantage is comfortDry feet and no puddles on the bottom are not just a convenience, it's a health issue, especially in the cold season. You don't have to worry about splashing from the engine or rain. ergonomics: you can freely move around the cockpit, change tackles and not be afraid to break the bottom against stones or driftwoods.
- 🌊 Automatic water removal: The system operates without human intervention while the valves are open.
- 🎣 On-site sustainability: The rigid construction of the floor allows you to confidently fish standing.
- 🛡️ Protection against damage: double bottom is harder to punch a sharp object at the bottom of the reservoir.
And it's also worth mentioning the versatility of cockpit boats, which are often equipped with a reinforced transcenza that can withstand powerful forces. outboardThis makes them ideal for long distances in open water, where speed and reliability come to the fore.
To increase the life of self-moulding floor valves, wash them regularly with fresh water after use on salt water bodies to prevent the mechanism from souring with salt.
Disadvantages and limitations of operation
Despite the obvious advantages, cockpit boats have significant disadvantages that you can not keep silent. weight Double bottom and reinforced cylinders make the boat considerably heavier than flat bottom counterparts (FBB), transporting in the trunk of a passenger car can be a challenge, and carrying to the water will require physical effort or the assistance of a partner.
The second nuance is sailability Because the floor is high and the sides are often high, the boat reacts more strongly to the side wind, and when the wind is strong, the boat can turn around, requiring anchoring or constant engine operation to hold position.
15-25 minutes.| Parameter | Cockpit boat | Flat-bottomed boat |
|---|---|---|
| Packaging weight | Tall (30-60 kg) | Low (15-25 kg) |
| Displacement | Displaces more water. | Minimum |
| Assembly speed | 10-15 minutes. |
|
| Comfort on the wave | Highly | Low. |
It is also worth noting the complexity repairIf you damage the inner layer of the floor or the valve itself, it can be extremely difficult to get to the site of damage, sometimes for quality repairs you need to completely dismantle the boat or use specialized equipment in the workshop.
Differences between cockpit and trans boat
There's a lot of confusion between the cockpit and the tranza boat, and the tranza boat is a rigid insert in the engine stern that almost all serious inflatable boats have, but the presence of a translance does not guarantee a self-draining floor. The boat may have a tranza but it may be equipped with a conventional one. bottom-inflatable (NDND) or plywood floorboard.
In a cockpit boat, the whole floor is a single inflatable structure with a drainage system. In a conventional transom boat, the water that gets in stays at the bottom until you scoop it out. The difference in behavior on the water is huge: in the first you walk above the water, in the second you can partially dive into the water that has accumulated at a strong wave.
Choosing between these options, ask yourself the question: where and how will you use the boat? For a quiet fishing on the lake in calm, a simple model with a small boat is enough. NDMAFor sea fishing, rafting on rough rivers or work as a lifeguard, it is needed. cockpit.
The myth of unsinkability
Many people think that a cockpit boat is unsinkable. It's not! If a balloon is broken, the boat will lose its buoyancy regardless of whether there is a self-flowing floor. The cockpit only removes water from the top, but it doesn't compensate for the loss of cylinder volume.
Maintenance and maintenance of the drainage system
To ensure that the self-embodiment system works faultlessly, it requires regular maintenanceSand, silt, algae and small fish scales can clog the drain valves. Before each trip, visually check the holes for contamination. A mechanical obstacle can keep the water from coming out at a critical moment.
After each trip, especially at sea, the boat must be carefully freshwaterSalt deposits crystallize and can damage rubber valve seals, breaking their tightness. Drying a cockpit boat takes longer, as moisture can linger between the floor layers. It is recommended to dry the vessel in a half-flattened state with open valves.
- 🧼 Valve cleaning: Use a soft brush and water to remove dirt from drainage holes.
- 🔧 Leakproofness check: Once a season, inflate the boat and check if the valves poison the air under pressure.
- 🌡️ Temperature: Keep the boat at room temperature, avoiding sudden changes that can deform PVC floor material.
⚠️ Warning: Never keep a cockpit boat fully assembled and drawn for months, causing cloth to break in the folds and reducing resource levels. reinforcement.
Rules for safe use on water
The operation of a self-draining boat dictates its own safety rules, and since the sides of such boats are often higher and the center of gravity is higher, the risk is high. tipping It's not allowed to stand up abruptly, move on a boat without having to, or make abrupt jerks with a rod when catching large fish.
Special attention should be paid weight-sharingPassengers should sit on banks (seats), not on boards. Shifting the center of gravity sideways can cause water to overflow over the side, and the self-emitting system will not have time to remove it if the angle of roll is too large.
☑️ Checking before exit
When you're driving at high speed with a powerful motor, water can be thrown in through a transom, in which case the cockpit system will cope with the volume, but this will put additional stress on the engine and reduce speed. door-wheel And adjust the angle of the motor to minimize the splash.
Safety on the water with a cockpit boat depends not only on the design, but also on the discipline of the crew: even weight distribution and smooth movements prevent critical roll.
FAQ: Frequently asked questions
Can you convert a normal boat into a self-driving one?
It's theoretically possible, but it's extremely difficult and expensive in practice, you have to cut a double bottom, you have to install a valve system, you have to keep the seams tight, it's easier and safer to buy a specialized model right away, because artisanal rework can disrupt the process. strength-plate hull.
How fast does water escape through the cockpit valves?
The speed depends on the water pressure (boat precipitation) and the diameter of the valves. Usually, a complete water exchange occurs in a few minutes. However, with a strong wave, water can constantly splash over the side, and the system will operate in a constant pumping mode, preventing water from rising above the floor level.
Do I need to close the valves when transporting a boat?
Yes, always, when transported by trailer or in the trunk, dust, insects or moisture can get inside, and closed valves prevent accidental damage from the inside of the mechanism. open.
Does the cockpit affect the speed of the boat?
Yes, it does. Boats with self-draining floors have more displacement and sailing, which reduces maximum speed and increases fuel consumption compared to lighter ones. seaworthiness This is a positive effect: the move becomes softer and more predictable.
Which material is better for the cockpit floor: PVC or Haipalon?
Hypalon (CSM) is more resistant to ultraviolet light and abrasion, which is important for professional use. PVC It's cheaper and lighter, but it requires a more careful attitude. PVC A tissue density of 1100 g/m2 will be sufficient.
