Comparison Gladiator A320TK vs Intex Explorer Pro 300 Boat Set

— Rowing. Boats originally designed to be rowed. Note that many of these models allow the installation of a mounted transom (see below) and the use of a motor; however, a powerful engine cannot be put on such a vessel, it is not suitable for high speeds, and the main method of movement is still oars. Boats of this type have a closed hull — the inflatable side runs along the entire perimeter of the vessel and does not have protrusions at the stern, unlike motor and motor-rowing models. But the presence of oarlocks is not strictly necessary: some rowing boats, mostly small single-seat models, are designed for rowing with a vertical oar, like a canoe, or short rowing oars, which also do not require oarlocks.

— Motor-rowing. Boats, originally designed for movement on motor traction, however, allowing use with oars; oarlocks are an obligatory piece of equipment in such models. From purely rowing boats, motor-rowing vessels differ primarily in the presence of a built-in transom (see "Transom"). At the same time, the inflatable part of the side has an open shape resembling the letter U: there is a transom between the “horns” of this letter, and the “horns” themselves protrude behind the stern. Such a design is considered optimal in a number of parameters, it allows the use of powerful and heavy motors that are not available for rowing boats (although, of course, specific restrictions on motors in d...ifferent models may be different). Note that boats of this type can differ markedly in characteristics and features: for example, some are close to rowing boats, others differ from motor boats (see below) only in the presence of oarlocks.

— Motor. Boats intended to be driven by motor power only and allowing the use of oars only in exceptional circumstances. The key feature of all such models is that they do not have oarlocks — so rowing (if at all possible) will have to be “canoe-style” with a vertical oar. At the same time, from the technical side, this is the most advanced type of inflatable boats. So, most of these models are designed for fairly powerful motors and high speeds, many of them have steering (see "Additionally"). And advanced motor boats are often made according to the RHIB scheme — a rigid keel hull with an inflatable board in the upper part (for more details, see "Bottom Type — Fibreglass Keel").

— Kayak. A variety of inflatable boats, similar in design to traditional kayaks (kayaks) — narrow and long rowing boats without oarlocks. In classic kayaks, paddlers sit one behind the other, and two-bladed oars are used for propulsion. However, among the inflatable models there are other design options — for example, relatively wide vessels, in which each rower works from only one side with a single-blade oar (like a canoe), as well as watercraft with a built-in transom and the possibility of installing a motor. The advantages of inflatable kayaks over traditional rigid ones are light weight, compactness during transportation, large buoyancy reserve and high carrying capacity. Among the shortcomings, one can note the difficulty in managing in strong winds (due to shallow draft and high windage), a relatively small capacity and (in some models) insufficient directional stability, which must be corrected by ballast.

The total number of seats provided in the boat is, in fact, the maximum number of adults for which it is designed. Usually, this number corresponds to the number of seats.

There are three things to keep in mind when choosing this indicator. Firstly, with the maximum number of people in the boat, it can be quite crowded and not very comfortable. Secondly, in addition to people, such boats often have to be loaded with luggage, which can be heavy and voluminous. Thirdly, the capabilities of the boat are limited not only by the number of seats, but also by the carrying capacity (see below). Therefore, if it is planned to carry large people and/or a large amount of luggage on the ship, it is best to choose a model with a margin for the number of seats.

As for the specific number, the smallest modern boats have 1 or 2 seats. Medium-sized models with 3 or 4 seats are also extremely popular. 5-seater options are relatively rare, and the largest models can accommodate 6 or more people.

The maximum weight of cargo that the boat is normally designed to carry. The cargo in this case includes both passengers and their luggage, as well as the engine and various additional equipment.

The carrying capacity stated in the characteristics clearly cannot be exceeded: although most inflatable boats are able to stay afloat even with severe overload, in such conditions controllability and stability noticeably deteriorate, wear increases and the likelihood of damage to the bottom or cylinder increases. We also note that there is no strict connection between the carrying capacity and the number of seats (see above): models with the same number of seats can differ significantly in permissible load. And it is important to take boats with a large carrying capacity if necessary, because this affects the density of materials, overall weight and price.

The type of bottom provided in the design of the boat.

All bottoms can be divided into flat and keel, each option has its own advantages and disadvantages. So, flat bottoms are relatively simple, inexpensive, convenient in shallow water (due to minimal draft) and allow you to go on planing with a relatively low engine power. On the other hand, the keel improves both manoeuvrability and directional stability, it allows the boat to effectively "cut the waves" at high speed and reduces the influence of wind. Thus, a flat bottom should be chosen for rowing or under a relatively weak motor for short distances; and the keel design is perfect for high speeds, powerful motors and long passages.

Both flat and keel bottoms can have different designs. In the first case, the options might be:

— Actually flat, it is also tension — the simplest bottom made of soft waterproof material stretched between the sides of the boat. The main advantage of this option is simplicity and low cost. In addition, the tension bottom is insensitive to minor damage: a small cut or puncture practically does not change its properties, does not affect the strength and seaworthiness of the boat. At the same time, the rigidity of such a bottom still turns out to be low, and for comfort it is desirable to use additional coatings with it.

— Flat inflatable(NDND). The so-called low-pressure infla...table bottom is a bottom made in the form of a separate inflatable compartment. Such surfaces are noticeably stiffer than tension ones, which allows them to be used without additional coatings and simplifies the deployment and folding of the boat. The inflatable compartment provides additional comfort: it dampens the impact of small waves and plays the role of thermal insulation, the latter can be useful on land. In addition, this design increases the carrying capacity and provides additional buoyancy in case of damage to the main cylinder. The main disadvantages of inflatable bottoms are relatively high cost and sensitivity to damage. In addition, such a bottom reduces the actual volume of the cockpit, and its rigidity is still relatively low, and it can be difficult to maintain balance while standing on the NDND.

Keel bottoms, in turn, can have the following design:

— Inflatable keel. The simplest type of keel bottoms, in fact, is a flat tension bottom (see above), supplemented by a keelson compartment, which turns into a keel when inflated. The advantages of such structures are simplicity and low cost, the disadvantage is low rigidity, due to which the bottoms with an inflatable keel have to be equipped with additional hard coatings.

— Inflatable keel ( NDND). An analogue of a flat inflatable bottom (see above), which has the same set of advantages and disadvantages and differs in the actual presence of a keel. This design differs from the inflatable keel described above in that the entire bottom is made inflatable, and not just the keelson. This provides rigidity and eliminates the need for special coatings. On the other hand, keel boats with NDND turn out to be less stable than their counterparts with an inflatable keel, they sit higher in the water and ideally require additional loading to reduce draft; Yes, and such bottoms are somewhat more expensive than analogues with an inflatable keel.

— Fibreglass keel. Keel bottom in the form of a rigid part made of fibreglass or other similar polymer. Models of this design are called RIB (RHIB) — "rigid hull inflatable boats." They combine the advantages of classic and inflatable boats: the vessel does not sink, even when it fills with water "on the sides", and remains buoyant even when the tank is completely deflated. In addition, high rigidity provides reliable support for people in the boat and allows the use of even fairly powerful motors; thanks to the latter, fibreglass keels are extremely popular in powerboats (see "Type"). The disadvantages of this option, in addition to the high cost, include the impossibility of folding, which is why you have to carry such a boat on a gun carriage, and store it in a fairly spacious room.

The type of cover for the bottom provided in the scope of delivery. Coatings are mainly used to provide extra rigidity if the bottom itself is too soft; this is true mainly for flat tension bottoms and boats with inflatable keels (see "bottom type"). Specific options might be:

— Rack slant. Flooring of several wide transverse rails, usually connected by a flexible mount. Thanks to this fastening, the slate can be folded into an "accordion" for storage and transportation, while in working condition the coating still turns out to be quite rigid.

— Rigid plywood flooring. Rigid coating made of waterproof plywood, usually, typesetting — consists of several separate segments, and for storage and transportation is disassembled for compactness. Plywood coatings combine good rigidity and low cost, which makes them very popular. In terms of strength and reliability, they are somewhat inferior to aluminium decking, but in most cases this drawback is not critical.

— Rigid aluminium flooring. Type-setting coating of aluminium segments fastened together when installed in a boat. In general, it is similar to plywood (see above), but aluminium is more durable and reliable, and it is absolutely not subject to corrosion. On the other hand, this material is expensive, which is why it is much less common.

— Inflatable flooring (NDVD). NDVD stands for “high pressure inflatable bottom”, however, this design should not be confused with an inflatable bottom (see “Bottom Type”): in this case, we are talking about a removable flooring. Due to the high pressure, such flooring turns out to be very rigid — noticeably stiffer than the bottom of the NDND type (although softer than plywood / aluminium coating). At the same time, the inflatable cover can be compactly folded during non-working hours, which ensures convenience in storage and transportation. Among the disadvantages of this option, sensitivity to damage can be noted.

— Without additional coatings. The absence of any coating in the scope of supply. Depending on the type of bottom (see above), this equipment may either mean that the boat does not require additional coating in principle, or that the flooring must be purchased separately. The second option is convenient in that you can choose the flooring at your discretion, without relying on the decision of the manufacturer.

Type of transom — mountings for installing a motor — installed on a boat or supplied with it.

— Built -in. This type of transom is a vertical board in the stern of the vessel; such a board is located between the aft ledges of the cylinder and, in fact, also plays the role of a tailgate. Built-in transoms are strong and reliable, they can be used even for quite powerful and heavy engines, and therefore motor and motor-rowing boats (see "Type") are equipped exclusively with such mounts.

— Mounted. Transom in the form of a separate device, installed and removed if necessary. Transoms of this type are found exclusively in rowing boats: the motor for such a vessel is far from obligatory, and when it is not in use, the mount can also be removed to reduce weight. Usually, a mounted transom is immediately supplied with the kit, but this nuance does not hurt to clarify before buying.

— Missing. The complete absence of a transom is found exclusively in rowing boats and kayaks (see "Type"). At the same time, some of these models do not provide the installation of a motor at all, others have a “seat” for a transom and can be purchased in addition if necessary; these points for each model should be clarified separately.

— Rigid. Seats in the form of planks, usually attached to both sides across the boat. Considered more reliable than inflatables, they have a traditional flat surface and are cheaper due to their simple design. On the other hand, when folded, the hard seats take up more space, and the convenience for passengers is purely symbolic.

— Rigid sliding. The rigid bars described above with the ability to adjust the location along the boat. They allow you to change the distance between the seats, or even combine two into one.

— Inflatable. Inflatable seats are easy to use and quite comfortable. They usually do not require special fasteners, and by changing the degree of pumping, you can change the hardness, adjusting the properties of the surface to the preferences of a particular person. In addition, such seats, when deflated, take up a minimum of space. Their main disadvantage is their relatively high cost.

— Soft. A type of seat used primarily in kayaks (see "Type"). They have a rigid base covered with foam rubber or other similar material, often equipped with backs. This design provides comfort on long trips and at the same time allows you to maintain maximum control over the boat.

— None. Some boats may not come with seats at all. One of the varieties of such models is miniature rowing b...oats (see "Type"), designed for one or two people and equipped with an inflatable flat bottom (see "Bottom type"), which plays the role of a seat. The second option is multi-seat boats, for which "seats" must be purchased separately, depending on the features of the planned application.

— Steering. This feature means that the boat is equipped with a steering wheel and special rods, which, when the steering wheel moves, turn the screw (s) in the direction necessary for turning; next to the steering wheel is usually also a throttle knob. Steering is found exclusively in RIB boats with fibreglass keels (see "bottom type"); it significantly affects the cost, but this is offset by a number of practical advantages. So, the steering wheel is usually located approximately in the middle of the cockpit, from where the view is much better than from the stern (especially in planing mode, when the bow of the boat is very high); and the helmsman sits upright at the helm, facing forward—more comfortable than the half-turn position when steering through the outboard two-wheel tractor.

— Water release valve. The presence in the design of the boat of a separate valve for draining water from the cockpit overboard. In many models, such a valve can be used both on the shore and on the move, and anyway, it greatly simplifies the removal of water that has got inside — otherwise it would have to be scooped out, or even turn the whole ship over.

— Carrying handles. The presence in the design of the boat of special handles for carrying the boat in an inflated position. By themselves, the cylinders used in modern boats usually have a smooth surface with a...minimum of protruding parts, as a result, they are difficult to grasp. Therefore, for additional convenience, separate handles are provided — they significantly simplify tasks such as pulling the ship ashore.

— Olocks. The presence in the design of the boat of oarlocks — special devices on the sides, in which oars can be installed when rowing. Each paddle is attached approximately in the middle and can move in a vertical and horizontal plane. Such an installation provides additional convenience and reduces the load on the rower's hands — otherwise you would have to work with only one oar, and constantly keep it on weight and risk releasing it into the water. However rowing with the use of oarlocks involves the position of the rower with his back forward, and is also poorly suited for some situations (for example, for manoeuvring in floodplains); but these devices usually do not interfere with rowing in other ways.

— Rym. The presence in the design of the boat of a ring — a special fastening for ropes, usually installed in the bow. Such a mount can have a different design and purpose. So, the classic eye is made in the form of a ring and is used both for the anchor rope and for the towing rope; but there are also “purely anchor” options — in the form of a stand with a groove through which the rope is passed (so that it is fixed in the right place and does not rub against the sides once again).

— Bulwark. The presence in the design of the boat of a bulwark — a barrier installed above the main cylinders; usually, such a barrier itself is an additional balloon. The bulwark performs several functions. The most obvious of these is an increase in capacity, comfort and safety: due to the increased height of the sides, the risk of objects or people falling out of the cockpit is reduced, more overall cargo can be placed there, and less spray gets through such sides. Also, the bulwark increases the longitudinal rigidity of the hull, besides, its volume can be separated from the main cylinders; All this has a positive effect on overall reliability. This feature is found mainly among high-end models designed for difficult conditions and long stays away from the coast.

— Fender bar. Acts as a shock absorber. The beam is glued along the perimeter of the boat, along the line of contact of the side with obstacles and serves as a fender when mooring the boat to wooden or concrete piers. It can be made of rubber, PVC, plastic and other materials. Of course, its installation on a boat carries some negative aspects. So, the right timber makes the boat somewhat heavier and worsens its twisting. Such a boat is more difficult to transport and store.

— Water breaker. A water chipper is a part of the fender — a strip of thickened material on the outside of the sides. This strip provides protection when mooring to a jetty, driving through aquatic vegetation, etc. And the water chipper is a “visor” bent down along the fender; its purpose is to prevent water from entering the cockpit of the boat, especially when moving at high speed.

— Handrail cable. The handrail cable is installed on the mounts on the outside of the sides and "encircles" them, in whole or in part. There are many uses for this feature. For example, a person overboard can hold on to the cable — this is easier than clinging to the cylinders themselves or other devices. Also, the cable can be used as a replacement or addition to the carrying handles (see "Additionally"), as a place for attaching various equipment, etc.

The maximum engine power allowed for this boat.

The power limitation is primarily due to the fact that not every boat normally tolerates high speeds. In addition, powerful motors and weigh a lot, which puts forward appropriate requirements for the strength of the transom. So it is extremely undesirable to exceed the permissible power: even at low thrust, the structure will be subjected to abnormal loads, and full thrust can lead to a rollover or damage to the boat.
