Open water is always fraught with risks that increase with the strengthening of the wind and the appearance of a wave, which is why many experienced water engines prefer to buy a new one. high-sidedUnlike the classic low-cylinder models, these vessels offer a more confident feel even in unpredictable storm warnings.
In this article, we will analyze in detail the design features of inflatable vessels of increased height, consider their impact on seaworthiness and help determine the choice of a suitable model. Safety at sea It starts with the right equipment, and this aspect is absolutely impossible to ignore.
Advantages of high boards for seaworthiness
The main function of a high balloon is to create an additional buffer between the water inside the cockpit and the external element. PVC When a wave meets a wave, it's the height of the side that determines whether the water will fly through it or whether the crest of the wave will safely break into an inflatable barrier, which is critical for fishing in large bodies of water, such as Lake Ladoga or Lake Onega, where a squall wind can overtake a wave half a meter high or more in minutes.
In addition, the increased height of the side often allows you to place inside the cockpit additional comfort elements, such as harunduki or elevated seats, without losing the buoyancy margin. inflatable tubes Large diameter also play the role of effective breakers when mooring to concrete walls or piers, protecting the bottom and trench from impacts.
It is worth noting that the high sides create a kind of “well”, in which the wind has less impact on passengers, creating a calmer zone, but there is also a downside: the sailing of the boat increases, which requires more careful control of the engine in strong side winds.
⚠️ Attention! High sides increase the sailing of the boat, which can lead to a strong wind demolition when the engine is stopped. Always consider this factor when drifting or fishing in windy weather.
Thus, choosing a model with cylinders with a diameter of 45-50 cm and above, you get a versatile tool suitable for both quiet fishing and for overcoming short sea crossings.
Design features and types of cylinders
Modern manufacturers offer various options for the performance of inflatable elements, and not all high-board The most common solution is to use large diameter cylinders, round or oval cross-section, which are attached to the bottom along the entire length, and this design ensures excellent stability and rigidity of the entire assembly.
The models with the so-called “inflatable cockpit” or double cylinders stand out, where the outer side is a continuation of the bottom, and the inner one forms a protective wall. Air Deck Technology High pressure inflatable floor (HPD) is often combined with high sides, creating a rigid platform that resembles a metal boat, but with much less weight.
An important element of the design is the presence of timber On high-end models, it is often made in the form of an additional tight rubber lining that protects the PVC fabric from being rubbed against the cables and mooring structures, and without this element, the life of an expensive material can be significantly reduced.
Technology of cylinder production
Cylinders are made by gluing or hot welding. Welded seams are considered more reliable and durable, since they exclude the stratification of the material under the influence of ultraviolet light and temperature changes, which is especially important for boats that are constantly in the sun.
When choosing, pay attention to the number of independent compartments. High sides often provide 3, 4 and even 5 insulated chambers, which ensures unsinkability even in the event of a serious puncture of one of the segments.
Model comparison: specifications table
To better understand the variety of offers on the market, we will consider specific examples of popular models that have proven to be reliable high-sided vessels.
The table below shows data for boats about 3.6-3.8 meters long, which is the most popular size for installing outboard motors with a capacity of 15-20 hp.
| Model boat | Diameter of the cylinder (cm) | Height of board (cm) | Load capacity (kg) | Features |
|---|---|---|---|---|
| Flagship 380 | 50 | 55 | 950 | A reinforced transnec, keelson |
| Solar 380 | 48 | 52 | 860 | BNDT, high inflatable seats |
| Cayman 360 | 46 | 48 | 750 | Compact, high stability |
| Hunter 380 | 50 | 54 | 900 | Protective belt, reinforced bottom |
As you can see from the table, loading capacity Models with a diameter of 50 cm and above are capable of carrying not only a crew of 2-3 people, but also a solid supply of equipment, anchor equipment and fuel.
When choosing a boat for trolling or long expeditions, the priority should not be maximum speed, but buoyancy margin and board height for safety.
Influence of the height of the board on controllability
Many newcomers mistakenly believe that the higher the board, the better, forgetting about the laws of hydrodynamics. balloon It does protect against water, but it also creates significant resistance to the wind, and when it's going full speed, it can lead to yaw, which is a self-producing change in course, which requires constant operation with the tiller or the presence of a stability system (autopilot).
In addition, the center of gravity of a boat with high sides can be displaced if the load is not distributed correctly. Passengers are not advised to stand up abruptly or move from side to side, as the sailing area contributes to roll. Management It becomes more lazy at low speeds, but on planing, such boats behave predictably thanks to a deep landing in the water.
It's important to consider the height of the transom. On models with very high sides, the transom is also raised higher, which requires the right fit of the diewood engine. If the screw is too high, cavitation and loss of traction will occur; if it is too low, water resistance will increase.
Experienced drivers recommend when installing the engine on a boat with high sides to conduct test swims with different loads to find the optimal angle of the trim.
Safety and equipment
The presence of high sides does not eliminate the need to comply with safety rules, but only adds specific nuances. The main danger in such boats is the risk of being overboard in a sharp maneuver, as they move back through the high altitude. flyboard Without outside help, it is almost impossible.
Therefore, the presence of safety liners (taut cables) along the inside of the cylinders is a mandatory requirement for safe operation, they allow you to stay in the cockpit under heavy chop or sharp braking.
⚠️ Attention! Never neglect to wear a life jacket, even if you are in a boat with high sides. In the event of a rollover, it is extremely difficult to climb back into a high boat in full gear.
It's also worth taking care of the scoop or pump. Despite the height of the sides, off-shore water can still get in through splashes or when landing on a wave. In tall boats, water accumulates in the deepest part of the cockpit, and it can be difficult to draw it out by hand.
☑️ Security check before exit
Care and maintenance of high cylinders
High-sided PVC boats require more careful care, since the surface area exposed to ultraviolet light and mechanical loads is much larger. PVC fabric on the upper parts of the cylinders, which are constantly in the sun, over time can lose elasticity and fade.
Regular treatment with special means (UV protectors) will help to prolong the life of the material, special attention should be paid to the places where the cylinder is docked with the bottom and the timber, where sand and dirt, acting as an abrasive, most often accumulate.
When drying and storing tall boats are more difficult to fold into a compact size, it is recommended to use original bags of increased size or store the boat in a semi-assembled form (with lowered, but not folded cylinders), if space allows.
When packing a boat in the cold season, let it warm up to room temperature before deflating. Cold PVC becomes brittle, and when high cylinders are folded, microcracks can form.
Compliance with these simple rules will allow your boat to last many seasons, maintaining its high seaworthiness and presentable appearance.
Frequently Asked Questions (FAQ)
How tall should a boat be to go to sea?
To go to sea or to large reservoirs, it is recommended to choose boats with a board height of at least 45-50 cm This will provide protection from waves up to 0.5-0.7 meters, which is the safety limit for small craft.
Can I install a powerful motor on a high boat?
Yes, high sides often allow for higher power motors, as the transom is stiffer and higher above the water. boat's passportSo as not to disturb the centering.
Is the boat with high sides sailing hard?
Sailing is really higher, especially when the wind is on board, which is offset by the greater weight and stability of the vessel, but requires the driver to be more active in steering and attention to wind gusts.
How to properly pump high cylinders?
Pumping should be done in stages: first to 50-60% of the volume, let the material stretch, then finish to the working pressure (usually 0.2 atm). It is important to use a pressure gauge, since in the sun the pressure in high cylinders increases faster.
