Diverse by design, “naduvnoj” function as the safe movement of the water through several compartments (at least three) that provide status. PVC boat love vodnomotornikov for compactness, simplicity and ease of use.
What is the difference between PVC boat
The material for the test, we started to collect in advance. If reviewing a single instance can be sorted out during the day, to share a few similar boats in groups and compare their characteristics — not an easy task. For starters, we classify the selection criteria.
The length of the boat. It depends on the size of the reservoir of usage, number of passengers, the motor, the availability of appropriate vehicles for transportation (usually the trunk of a station wagon, or household trailer).
The material of the soles. This is usually water-resistant plywood with edging of Al-profile and metal stringers. Less — cellular steel deck, inflatable bottom, low pressure (NDND), or high (Airdeck). Slatted flooring small rowing boats, hard aluminum, or fiberglass the bottom of RIBA left out of the article.
Contours. Given the large width and the specifics of the bonding material, it is possible to allocate principal part of the lower body. The most common subcrenata classical form with Central keel, and moderate deadrise at the transom. Tunnels with air discharge provide skagi on the cylinders to obtain a display effect. Inflatable bottoms range from completely flat to keeled. For extreme conditions the bottom of the increase (“file”) high molecular weight polyethylene.
The cylinders of material – PVC fabric of different density. Hypalon poorly distributed because of the high cost (the main advantage — the ability to survive for long periods under the sun). Rubberized fabric in the last century, since it required greater attention and care.
The method of fastening the cans-seats and attachments the hinges on the cylinders, or connecting Lectro-likes. The latter is more comfortable and functional, so be constructive the vast majority of manufacturers.
Select to compare
If you approach the issue in the most meticulously, this test will result in a whole book devoted to “rezinomotornaya fleet.” At the same time to judge all the boats of PVC on a single example is wrong. Therefore, we chose one instance of each popular size of 360-370 cm
After the classic models trusted to defend proven “Cayman N-360”. Inflatable bottom low pressure — the Flagship carrier of ardeca chose Badger, not missing the opportunity to check its modification with metal soles.
|Model||Type bottoms||Weight, kg||PLM, l/s||Ø of the cylinder,cm|
|Kayman N-360||Plywood soles, 2 stringer||70 kg (2 x 35) + stringers||25-30||46|
|Badger SL370AL||Aluminum soles, 4 stringer||80 kg (2 x 40)||25||45|
|Badger FL360AD||Airdeck||55 kg||15||43|
|The flagship 360U||NDND||45 kg||20||47|
Expectations ease from the boat with aluminum soles compared to plywood is not justified. Partly to blame for this design. If “plywood” Cayman for bottoms and cylinders used a different material with a density of from 850 to 1150, the Badger all made from PVC 1100 g/m2.
The starting point for the navigation in the “air” version is build boats. To compare the time, we were divided into teams of two and started to work.
Unloading from the car. In this category leads Paolina classic design as the kit is in two relatively small bags of approximately equal weight. Removing two seats to 35 kg it is much easier for your spine than one, but weighing 50 pounds.
Spread our wings. When the team NDND finished to expand the shell, “Pionki” were in the process of assembling the deck and installing the stringers. Airdeck was in the middle, because in order to insert a few boards, a lot of the time not needed. Victory in the category for inflatable bottom low pressure.
Always ready! Inflating the boats had to be carried out in two stages. The fact that the first crews with inflatable bottoms used two-stage compressors “Bravo” and Pioline — normal “frog”. We considered the conditions of competition are unequal, and all began to pump regular foot single chamber pumps. This turn of events, the team with NDVD accepted without enthusiasm, as a result, it was on the penultimate place. Because “stuff” ardek to the passport pressure and did not work — went down the hose.
In a good way. Originally wanted to hold a race at maximum speed under power 25 power. But as it turned out, in a similar size model with inflatable bottom have a lower maximum power of the engine. So I had to settle for trusted “Amahai”-15. This PLM is still easy to wear one, but four people confidently slide.
Of special mention is the carrying case. Everyone liked the quality and strength of Cayman packages, however, if you need shelter from the weather with waterproof fabric Badger, despite the lower strength, has the advantage.
Full speed ahead!
We tested the boat with one skipper, together with the passenger on the front Bank, and with four passengers. Speed performance reflected in the table.
|Boat||1 person||2 people||4|
|The flagship 360U||39||35||31|
“Maximum speed”. All subjects showed themselves quite well. Of course, to the dynamics and speed of 48.5 km/h Caiman with dvadtsatipyatiletnih motor was far away, but, nevertheless, the participants coped with the task. Since the goal of testing was not the fundamental study of the class of vessels, and evaluation of consumer qualities, that we haven’t made precise measurements of pressure in the cylinders, the location of the riders. Although the experiment download To-360 showed a very significant impact changes weight at speed.
Timing. Assembly option with duckboards will not take more than thirty minutes. To disassemble, wash and wipe the design after fishing, you will need about an hour. This plan has the CLEAR advantage. The Assembly and disassembly you will spend two times less time.
Features. Speaking about the Airdeck, we note the need to purchase an electric pump. To pump up the bottom of the regular “frog” — lesson for the diligent. Even with a nominal pressure at a speed above 30 km/h airtek slightly curved, that the vessel may not achieve maximum performance. The same applies to full load. The engine power also should not exceed, as to keen on four-stroke engines.
Impressions. The bottom of the low pressure surprisingly aroused positive emotions. It was quite hard, people stood confidently. But it is desirable to hide the carpet from falling cigarette butts, knives, and also from the scorching sun.
Maintainability. Voluminous bottoms, in contrast to paialnik, almost beyond repair. When left in the sun the casing will burst at least a few connections between the top and bottom “sandwich”, the deck will become shapeless “sausage”. And if Airtec can be replaced by plywood or aluminum soles, NDND is an integral part of the design. This is worth remembering, leaving the watercraft on the beach or the deck of a yacht.
Overall this test confirmed the purpose of the different subjects.
- “Pajaki” good as the only mobile kit that complements the hard case.
- “Airtek” will appeal to fishermen, who do not need a drive of the maximum PLM.
- NDND glissirovat with minimal motor, softens the blows of the waves, going fast. So useful as a tender for big boat or yacht in the presence of a pump or a shady space for storage.
