Inflatable kayak: everything you need to know to choose

Long-distance boat trips

Do I need to "campaign" for long-distance boat trips? Many descriptions of such voyages have been published. They tell about the beautiful nature of our country, clean transparent rivers with picturesque banks, seas, reservoirs, fishing, accidents and adventures; the authors describe cities and villages, meetings with interesting people - in a word, everything that gives a tourist travel a unique charm. I think that all this should not be repeated.

We can say with confidence that anyone who has ever sailed along the endless blue roads of our homeland will "get sick" with water tourism forever, and at the same time will give preference not to a tourist motor ship, but to a simple motorboat devoid of many conveniences ... It is difficult to overestimate the importance of long-distance tourist voyages. For the elderly it is recreation, for the young it is sports. This is the acquisition of skills in maritime affairs and mastery of technical specialties, the study of the native. countries, expanding their horizons and, finally, the beneficial use of leisure. However, such hikes may turn out to be not a joy, but a burden: it all depends on the experience, discipline of the participants, and especially on the preparation for the hike.

Careful and comprehensive preparation for swimming is the key to success!

Select a vessel

There is a lot of talk and writing about choosing a vessel for travel. How many authors, so many opinions. But the choice is still small. Few of the amateur tourists can choose a motorboat or a boat to their liking; the majority use the small boats available at hand, somehow adapting them for long-distance tourism.

The situation with motors is no better: so far both "Moscow" and "Veterok" and "Whirlwind" are rare in our stores.

One should not, however, despair: any strong and stable motorboat (boat) with an outboard or stationary motor can be used for a long trip. The only question is which route to go on this vessel and how to ensure the safety of navigation on it, but more on that below.

While hiking, I have come across motorboats and boats of various types. There were also homemade ones. Some of them were excellently designed and had a beautiful view, but there were also unsuccessful ones, constructed, obviously, by inexperienced people, although made with love and soundly. These ships were equipped with the most incredible engines, including the old outboard motors such as "LM-1" or "LMR-6".

I cannot agree with the authors of the article "What kind of boat does a traveler need?", who easily and completely reject outboard motors as unreliable, describe the "horrors" of sluicing a cabin boat and categorically speak out only for an open planing boat with a stationary engine and column (or water cannon). Perhaps this solution is the most attractive and affordable for those "tourists" who will ride the boat after breakfast for 2-3 hours and in the evening in the chill for the same amount (look, and passed 200 km!), And the rest of the time the boat is transported by car. In fact, for the purposes of long-distance tourism, planing and displacement, and open and closed motor vessels with stationary and outboard motors can be and are successfully used.

With skillful use and availability of spare parts, outboard motors are quite reliable, and most importantly, affordable. Yu. V. Emelyanov, in a note placed in the same, third issue of the collection, rightly criticizes the authors, arguing that many other types of tourist boats also have every right to exist.

Contrary to the opinion of com. Bazunov and Gantman, it should be emphasized that the presence of a cabin on a motorboat intended for a long voyage is highly desirable. Safety and maintenance in the perfect order of things, bed, food; always ready places for rest and sleep; reliable shelter from bad weather and heat - these advantages of a cabin boat are very important and are the key to a good mood of the crew.

Fans of dashingly rushing 100-200 km on a boat with a powerful engine should not gasp and groan about the high fuel consumption. Of course, the struggle for efficiency should be carried out both along the line of improving the contours of the hull, and along the line of improving the engines, but a radical way to save fuel is to use for long voyages either displacement boats with good contours, equipped with four-stroke engines of low power, or light planing motorboats. Such vessels provide the greatest mileage per liter (kilogram) of fuel. For example, a small displacement boat with good contours with a 10-horsepower four-stroke engine with a specific fuel consumption of about 300 g/l. sec./hour develops a speed of up to 15 km/h (3 kg of fuel per hour), that is, it travels 5 km per 1 kg of fuel. Planing light motorboat - the same "Kazanka" - with two passengers under the "Moscow" engine at a flow rate of 450 g/l. a s./hour develops a speed of 28-30 km/h (4.5 kg of fuel per hour), that is, it travels 6-6.5 km per 1 kg of fuel.

How to choose a boat, boat or other powerboat

Motor boat - a vessel with an outboard motor; boat - with a stationary engine. In real life, the border is blurred, boats are called ships and with an outboard motor. In this article, for simplicity, we will use the term "boat".

Now on the market of motor boats there are so many offers that it is not difficult for a beginner to get confused. We need a small "educational program". This is the guide. Its task is to show you the main possibilities of boating and help you in the difficult matter of choosing not only the boat itself, but also equipment, accessories, services, etc.

It is impossible to foresee all aspects and subtleties, especially when all manufacturers are constantly improving their products and offering new ones. So this guide is not a substitute for your sales assistant. But it will allow you to narrow down the parameters of your search as much as possible, save time and competently set the task for sellers - experienced sailors from the "Sailor".

For a true seller, the best reward is a satisfied customer. It is especially pleasant when customers, months later, having fully enjoyed the boat, say words of gratitude. There is also a commercial sense in this - a satisfied buyer will recommend a good seller to his acquaintances.

"I take a block of marble and cut off all that is unnecessary" Auguste Rodin

To give you some idea of ​​the spectrum (far from complete) of the capabilities of modern powerboat, we first describe one wonderful vessel. This is a "St. Petersburg" cabin boat Silver Star Cabin 650 with a two-piece hull:

  • outer casing made of aluminum, for strength (bottom thickness 4mm).
  • seamless plastic inner element: noise and heat insulation, easier to clean (no seams); greater safety of passengers (no sharp metal corners)

Its dimensions (6.5 m long and 2.4 m wide) and speed capabilities (speeds up to 41 knots (75 km/h)) make it suitable for almost any purpose: from leisurely romantic travel

… to high-speed entertainment such as crazy racing and jet skiing.

On this boat you can walk along large reservoirs. It can be equipped with modern navigation equipment and motors of different power (outboard and stationary). Its sides are filled with expanded polystyrene, which makes it 100% unsinkable. It is very easy and safe to operate.

Outdoor enthusiasts involved in long hikes during water tourism will surely appreciate the inflatable kayak. For experienced raftsmen, it takes only 15-20 minutes to assemble and disassemble it. The question that interests many rafting enthusiasts is which inflatable kayak is better?

Types of kayaks

A kayak is a light, narrow boat with sharp lines. The boat is steered using a two-bladed oar, which distinguishes the kayak from other rowing boats. There are one-, two- and three-seater floating craft, where the rowers are placed one after the other face in the direction of travel. Three-seater kayaks are rare, more often sports and tourist boats are single or double.

Distinctive features of these boats are: hull tightness from water ingress through the seats, oars design feature (with different blades turning angle or with the same), equipped with air cylinders on the bow or stern to create unsinkability. All boats of this type are divided into two large groups: collapsible and non-collapsible. The first type is usually single, made of plastic. Non-collapsible models are used to pass difficult rapids and waterfalls, not intended for long water trips. Another name for a non-separable vessel is a kayak. Depending on the manufacturing technology, collapsible kayaks are divided into the following types:

  • Multi-section plastic boats;
  • Frame boats, consisting of a wooden or metal frame covered with skin.
  • Inflatable
  • Frame-inflatable, similar in design to frame, but with inflatable balloons, creating a floodability reserve.

Collapsible kayaks are used on multi-day hikes because they are durable and easy to carry. The most widespread are inflatable and frame-inflatable boats.

Inflatable kayaks

The advantages of inflatable kayaks, in contrast to other types, are:

  • Light weight, two to three times less than frame ones.
  • High lifting capacity
  • The air creates a reserve of unsinkability, and at the same time stability, especially in rough water and with strong rapids.
  • Small draft for comfortable rafting in shallow water.
  • Compact size when assembled, making it easy to transport the boat.
  • High "survivability" due to the fact that if the hull is damaged by stones, the boat will not go to the bottom, since the remaining intact sectors with air will keep it afloat. And if it breaks through the bottom, the water will not rise above the waterline.

At the same time, there are some disadvantages: difficulties in handling in strong winds, small capacity of most models of inflatable kayaks. In addition, the speed of this type of ships is less than frame ones by an average of 1-2 km/h.

A monolithic version is more common on the market, which is more convenient for assembly. From double-layer boats, the cylinders must be pulled out to inflate, then reinserted. In this case, it is periodically necessary to shake out the sand that has got between the cylinders and the shell.

The hull of the boat has round bilge lines with a transom stern. The dialing system is transverse. The keel, stem, counter-tibers, frames, beams are laminated. The outer sheathing is glued slatted. The bow part of the hull is sunken, in the aft part there is a niche for the outboard motor. To increase seaworthiness, a wooden coaming is installed along the inner edge of the side. The freeboard is protected by a fender.

Outfitting in the version of a working (cargo-passenger) boat includes longitudinal and transverse banks and removable floorboards. An open glazed wheelhouse (without a stern wall) is installed in the bow of the hull. On the roof of the wheelhouse, handrails and a small mast for navigation lights are installed.

The boat is designed for the installation of outboard motors with a capacity of 9.9 liters or more. ... up to 15 liters. ... This power allows the boat in displacement mode to reach speeds of up to 13-14 km/h. We recommend a 9.9L Mercury Command Thrust motor. ., t. it has a reduced gear ratio (2.42: 1) and an enlarged propeller. Also, the boat can be equipped with a stationary engine with a capacity of 20 liters. ...

The wheelhouse is equipped with a remote engine control handle and a mechanical steering gear with a steering wheel.

Standard equipment: - Electric bilge pump with float switch. - A 200 liter fuel tank built into the body. with a booster pump. - Accumulator with a capacity of 60 Ah in a plastic box. - Lamp in the wheelhouse. - Navigation lights according to COLREGs 72. - Drainage pump control panel. - Switch panel with fuses. - 12V socket. - Mooring and anchoring device (bow bitteng, mooring cleats and bale bars).

The displacement boat of the Askold-26 project can be produced in various modifications: - In the form of an open launch with a steering console in the stern. - In the form of a small fishing boat. - In the form of a cabin displacement boat. - In the form of a motorcycle seller.

In versions of a motor-sailer and a cabin boat, an extended wheelhouse is installed on the ship, and a self-draining cockpit is equipped in the stern.

The layout of the living quarters provides for: - A toilet with a pumping yacht toilet and a sink. - Galley with sink and gas stove. - Two bunks in the bow. - Salon with a table and two sofas. The helm station is located in the cockpit.

Today there are a huge number of boats and boats and each person will be able to choose an excellent option, taking into account their individual needs. In turn, boats are divided into different classes: sports, pleasure, sports and pleasure, high-speed and others. At first glance, it may seem that you can easily get confused in them, but I will try to tell you about them in such a way that a beginner can understand.

For fans of water walks and lovers of water tourism, the issue of choosing a boat is relevant. There are plenty of offers on the modern world market. In addition to the fact that you need to decide on the material of the hull, the manufacturer and the specific model of the boat, design and mass of other characteristics, it is necessary to pay special attention to the choice of the propulsion unit. Let's dwell on one of the most popular options - water jet boats.

Water-jet cabin boat: Prerequisites for creation Operating principles

Bill Hamilton is considered to be the official creator and popularizer of water cannons, who began mass production of HamiltonJet water jets in the 1950s. However, the beginning of the first water-jet engines was laid long before it. The prototype of the first water cannon was a steam-driven pump for pumping water from the holds of ships with the release of a stream of water through the stern, the creation of which dates back to the middle of the 18th century. So what is the structure of a jet boat?

The main components of the jet propulsion unit are:

  • impeller (rotating propeller)
  • water jet (water intake)
  • straightener (counter-propeller)
  • reversible -steering device

A simplified diagram of the action of a water cannon looks like this:

The water flow moves through the jet tube due to the rotation of the impeller and, accelerating, it is pushed out through the nozzle. Due to the fact that the nozzle has a smaller diameter than the jet pipe, the water flow "narrows" and accelerates, a compact jet of ejected water is created, which sets the ship in motion.

The force of the water jet or "stop value" is determined by the speed of rotation of the engine itself.

The reversing steering device allows you to change the direction of the water flow, which, in turn, regulates the direction of the vessel. The reversing deflector (deflector) makes it possible to shut off the flow from the nozzle or turn the water stream back, which leads to braking or reversing.
