How to deflate rubber boats

　　It depends on what kind of air nozzle you buy. Ordinary rubber boat is black. Turn it open directly. Hold a small stick against the small plug inside the air valve. Advanced rubber boats are usually grey air nozzles. Turn the horizontal bar outside the air nozzle. Then look at a spring-shaped protuberant part inside, press it downward, then rotate counterclockwise and loosen it. When inflating, twist it in the opposite direction and then inflate it. 　　Do you love water sports? How to choose your favorite inflatable yacht? Sailing yacht will give you a detailed explanation here, hoping to help you choose inflatable yacht. 　　The following issues should be considered in the trilogy of ship selection: 　　1. Balance the contradiction between portability and water performance to choose the appropriate floor form. 　　2. Choosing the right hull material according to the ship's working environment 　　3. Buy the biggest boat in your budget and space requirements 　　I. Appropriate Bottom Plate 　　The bottom structure of inflatable vessel directly affects the portability, convenience of installation, storage volume and performance of water performance. Synthetic plastic, FRP or aluminum alloy inflatable vessels with V-shaped bottom have good flight performance, but they must be transported and stored by trailers and hangers. Flexible fabric bottom boats can fold very compactly, but at the expense of some water performance. If you want the ship to take off at a speed of at least 5mph (8km/h), then a semi-rigid bottom ship is necessary. 　　Soft-bottomed rubber boat 　　Economical boats like mini-rubber boats or mini-rubber boats are very easy to install and carry. They are better suited for coastal and small-scale waters, fishing or camping. Their boards are inflatable and do not need to be removed when they are normally stored. Driven by oars or electric motors, these rubber boats with swimming rings are the lowest in price and the most basic in function. 　　Rollable boat 　　Similar to the previous rubber boat, this kind of boat does not need to dismantle the bottom plate during transportation. We can open it, inflate it and launch it in a few minutes. The floor is made of fabric with wooden slats on it. You don't have to take these strips down. This boat has a stern plate, so you can use a small horsepower hanger. The boat has the advantage of simplicity, but its flat-bottomed and small horsepower drive design prevents it from taking off and is only suitable for activities in ports and calm waters. 　　Sports boat 　　The bottom plate of a sports inflatable boat is removable, usually made of composite wood or aluminium alloy. A through aluminium fixed groove is used to fasten the bottom plate from the sides of both sides to form a whole. When the bottom plate is installed properly, the port and starboard air chambers and the conical keel air chambers are inflated, the bottom of the ship is tightened to form a shallow V shape, which makes it have better turning traceability and drainage performance than the flat-bottomed ship. This form of floor makes it heavier than ordinary rubber boats, but it can install 6-25 horsepower external hanging machine, run faster, cost-effective. 　　Inflatable Boat 　　A sport boat changes its wooden floor into a high-pressure inflatable floor and becomes an inflatable bottom boat (sometimes called an inflatable bottom boat). It combines the excellent performance of sports boats and the light weight and portability of soft-bottomed boats. Its unique high-pressure inflatable floor (pressure up to 11 psi) is very light. When deflated, it can be rolled up in the boat. It can take off immediately after launching. We are amazed that the small horsepower external hanger can achieve good performance. This is due to its smaller weight. The boat can bend slightly to absorb the shock of waves, which may throw people out on a hard-bottomed boat. Although it's a little more expensive than a regular sports boat, it has many advantages, not mediocrity. Installation time is very, very short! 　　Rigid Bottom Ship (RIBs) or Hull Ship 　　RIBs have a real "boat" feel and performance, appropriate hardness and deep V-shaped bottom. Its fiberglass hull can chop waves like an ordinary hard-shell ship, and it can be free from wear and tear under the impact of high-speed movement, sandy rocks and submersible tanks. But unlike hard hull ships, its inflatable bulkhead makes the hull more stable and buoyant. 　　However, it has excellent performance and can not take into account portability. The hull cannot be disassembled and carried in folding bags. Ventilation takes up less space than non-ventilation, but it still takes up a certain place. Therefore, we generally recommend it for those who are conditional to store it on the deck of the mother ship or on the hanger or on the open deck after deflation. Of course, its light weight also makes it easy to transport by trailer. 　　Compact or foldable RIBs 　　The compact R

How many years can a rubber boat last?

　　It depends on what area you use, like the rubber boat I used for up to four years. 　　The reality is gone. The products made in China are much stronger than before. But there is still room for improvement. Military use lasts longer, but it's too heavy... The main factor affecting the life of rubber boats is ultraviolet radiation. Therefore, the main way to prolong life is to prevent ultraviolet radiation.

To play yacht, start with choosing yacht

　　Yacht industry and yacht consumption are maturing, and yachts that can be purchased range from 34 feet below to 150 feet. For those who first contact yachts, it is difficult to understand the difference without a little effort. Fortunately, all this can be handed over to yacht agents. But if you can understand what kind of yacht you need, it will be easier for yacht merchants to find the right yacht for you.

What's the difference between a few hundred yuan inflatable boat and a PVC rubber boat?

　　Material differences: 　　From the material point of view, the material thickness of this kind of in** x inflatable boat on Taobao is generally about 0.4mm PVC or plastic material. The material thickness is thin, and it is designed as a single chamber. That is to say, there are only one chamber or two chambers. Professional rubber boats are made of professional inflatable boats: imported PVC material, 0.9mm thick, with 1100D strength fiber mesh in the material, which is equivalent. A layer of strength fiber mesh between two layers of PVC material can increase tension and impact resistance, and this kind of PVC material is added with anti-ultraviolet material, which can not deform or crack and leak under long-term sunshine, and this kind of PVC material has replaced the traditional pure rubber material and become the mainstream material of today's inflatable boat. 　　Professional PVC rubber boats all adopt multi-chamber design, that is to say, a boat has 3-6 air-filled holes, which can still maintain the buoyancy when one of the air chambers leaks, so the multi-chamber design will make the crew safer. 　　Distinction of components: 　　Compared with in** x rubber boat, the professional PVC rubber boat has stronger oars and thicker aluminium alloy material, which can ensure long-term use without breaking or cracking. Common parts, such as oar lock, are made of plastic and metal buttons, which can ensure that they are not damaged by excessive force in the process of frequent sliding. 　　Weight difference: 　　In fact, to judge whether a boat is good or bad, just ask the weight of the seller's boat. The weight of a professional rubber boat about 2.5 meters must exceed 30 kilograms. If the weight of an inflatable boat in ** x should be a little more than 10 kilograms or lower, and above the price, the price of a professional PVC rubber boat should be more than 2.5 meters. If the price is too low, you should pay attention to whether you have any questions. That's the problem. 　　Suspension power difference: 　　Most in** x inflatable boats do not have suspended power tail plates. If you need to add electric or fuel outboard engines, you need to buy stainless steel tube trailer tail plates at a price of 140-170. At this time, please pay attention to the weight of your machine, which means that you can only choose a small machine with 2-3HP horsepower. For 3-4 people in** x inflatable boats with a length of about 3 meters, you can only choose a small machine with 2-3HP horsepower. This kind of power is obviously not enough, but if you need to hang a bigger power outboard engine, such as the 6HP outboard engine, the weight of this power machine is generally around 20KG. The stainless steel bracket on the inflatable INX boat can not bear such a large weight, which is manifested by the bending of the stern, and the engine will sink into the water. 　　Professional PVC rubber boat tail has a professional Trailer tail plate, the tail plate thickness is generally 30-45 mm, such thickness is enough to withstand 23-50 kg of the weight of the ship's engine, that is to say, you will not restrict the power size of the ship's engine because of the ship's reasons. 　　Price difference: 　　Generally, the price of in** X Series inflatable boats is about several hundred yuan. The price of professional PVC net-clamped motor boat cloth rubber boats is generally between 2000 and 5000 yuan. There is still a big difference, but if the average cost is different, because the latter can be used for a long time without damage, and the former is mostly 3-5 times of life. 　　Ways of use: 　　Most of the inflatable boats with hundreds of yuan are toys used in swimming pools. This kind of boat absolutely cannot enter natural waters, because the hull and seams can not withstand the impact of excessive water spray or sea waves from external forces due to the shortcomings of hot melting technology, which can easily cause pressure loss and material tearing. This is a very dangerous thing in rivers, lakes and seas.
