Transportation flyboat It's not just a way of getting to the fishing site, it's also a serious test of the material part of your equipment. PVC It requires a special approach to load distribution to avoid irreversible deformations or punctures while driving on the highway. Many owners underestimate the aerodynamic drag that creates a volumetric object on the roof, which directly affects fuel consumption and stability of the car at high speeds.
Mistakes in fixation can cost you not only a spoiled mood, but also expensive equipment or, worse, cause an accident. Boat anchorage It should be rigid, but it does not damage the cylinders, and in this article we will discuss all the nuances, from the choice of the type of trunk to the inflatable floor and floorboards, so that your way to the water is safe and legal.
It should be noted that the rules of the road clearly regulate the dimensions of the protruding cargo. If your boat assembled with the engine and things exceeds the permissible limits in width or length, you will need a special permit and the installation of warning signs. However, for most standard models up to 4 meters long, a competently assembled kit on the roof is enough.
Selection of type of luggage system for transportation
The first and most important step is to find the right base. cross-section They are often rounded, which is not ideal for fixing round cylinders, but is quite applicable when using additional elements. Aluminum profiles are preferable to wooden bars, since they do not absorb moisture and do not rot, but wood is sometimes used as a temporary solution to create a flat area.
There are several proven laying schemes, the most common is to place the boat in its assembled form (with a tanning board and stringers) directly on the crossbars. Alternatively, using special soft mounts or covers that distribute pressure and protect the body. PVC It is important that the fulcrum be on the rigid elements of the boat's structure, not on empty segments of cylinders.
⚠️ Attention: Never fasten the boat only by the handles or belts sewn to the cylinders - they are not designed for wind load and can come off, leaving the cargo without fixation.
For owners of cars without rails, there are systems with suction cups or temporary attachment to doorways, but for regular transportation of heavy boats they are less suitable due to the risk of damage to the body and less load capacity. boot It must withstand the weight of not only the boat, but also dynamic loads during braking and cornering.
- 🚗 Staff rails: Ideal for the installation of universal crosses, provide high load capacity.
- 🏗️ Temporary supports: Suitable for rare trips, require a thorough check of tension before each flight.
- 🛡️ Protective linings: Rubber or foam pads are mandatory to prevent metal from coming into contact with PVC.
Preparation of the boat for transportation
A fully pumped boat creates a huge sailing stain, so experienced water engineers recommend putting pressure on the cylinders slightly before leaving, especially if there is a long way to go or a change in air temperature is expected. work pressure must remain sufficient to maintain the shape, otherwise the cylinders will begin to rub against the attachment.
The transom board and paioles (floor) must be securely fixed inside the cockpit. If you are carrying a boat assembled, make sure that you are not in a position to be a part of the boat. aluminum-floorboard They do not have sharp edges that can damage the inner surface of the cylinders when vibrating. Stringers are better laid along the side or fastened over a transom board, wrapping them with a soft cloth.
☑️ Preparing the boat for the way
Pay special attention to the cleanliness of the bottom of the boat. The sand, small stones or fish scales that remain inside will act as an abrasive when vibrating, gradually destroying the structure. PVC materialAlso make sure that oars and other long objects are securely fixed along the side and do not protrude beyond the dimensions of the car by more than the permitted norms.
Schemes and technology of fastening of cargo
The most reliable attachment scheme involves the use of at least four locking points: two in the nose and two in the aft. The belts are passed through the interior of the car or special holes in the doorways (if the design allows), but in no case should you press the door seals, otherwise you risk damaging them or leaving the car open. sling-string It is preferable to conventional ropes, as they do not stretch and allow you to accurately control the force of the tightening.
When stretching the belts through the roof, it is important to observe symmetry: the tension angle should aim at 90 degrees relative to the longitudinal axis of the boat to prevent the load from moving left or right in lateral wind. If the boat is long and hangs from behind, be sure to use an additional flag or marking to indicate the size.
| Mounting element | Materials | Recommended effort | Risk for PVC |
|---|---|---|---|
| Thunderbelts | polyester | High (controlled) | Medium (needs gaskets) |
| Rubber harnesses | Rubber | Low/Mediocre | Tall (may jump) |
| Rope (knots) | Polypropylene | Depends on skill. | Tall (friction) |
| Special. Grids. | nylon | Uniform | Low. |
Why can't we use regular ropes?
Vibration on the track causes knots on the ropes to spontaneously untie (“crawl”). In addition, a thin rope under strong tension cuts the soft material of the balloon like a knife, unless you use wide protective linings.
To protect the contact of the belts with cylinders, use wide strips of dense fabric, old towels or special plastic corners, this will distribute pressure and prevent the formation of scuffs. heating Sun belts can change their tension, so the first stop should be mandatory to re-check all nodes.
Protecting PVC from damage in transit
The main enemies of an inflatable boat on the road are ultraviolet, friction and temperature changes. Prolonged exposure to direct sunlight can lead to overheating of the air inside the cylinders and a critical increase in pressure, which can rupture the seams. So if you plan to park in the sun, it is better to cover the cargo with a light awning or at least turn the boat upside down (if the design allows).
Friction occurs in contact with crossbars and belts, and even the tiny movements of a boat when a car is moving can erase the PVC protective layer to the strings for several hundred kilometers. protectorThey are glued to cylinders in places of constant contact with the trunk.
- ☀️ UV protection: Use covers or awnings to reduce heat load.
- 🛡️ Mechanical protection: Lay soft material under all belts and rigid elements.
- 🌡️ Thermoregulation: Control the pressure in the cylinders in case of a sharp change in the weather.
Before a long trip, treat the surface of the boat with a special PVC polymer – this will create an additional sliding layer that reduces friction and protects against burnout.
Also worth considering is the chemical compatibility of the materials: some rubber or plastics in cheap belts can react with PVC plasticizers, leaving unstainable stains or softening material. Use only certified rigging products.
Traffic rules and dimensions
According to traffic rules, cargo protruding beyond the dimensions of the vehicle in front or behind by more than 1 meter, and also more than 2.55 meters wide, must be marked. For boats on the roof, the most relevant rule is the rear ledge: if the stern of the boat or the engine sticks out more than 1 meter from the edge of the body, a sign is required. "Large-sized cargo" In the dark, a red light or reflector is used.
The height of the vehicle with the load should not exceed 4 meters (some sources indicate 3.8 m for bridges), which is rarely a problem for passenger cars with a boat, but it is worth considering when entering low arches or parking lots.
⚠️ Attention: A fine for violation of the rules of transportation of goods can be imposed not only for the absence of signs, but also for unreliable fastening, creating a threat to other participants in the movement.
Traffic police officers have every right to stop a vehicle if the load seems dangerously unstable, so visual neatness and obvious reliability of the mounts is also a matter of no problems with the law, make sure that the license plate and taillights are not covered by the elements of the boat or belts.
Features of driving with cargo on the roof
Putting a bulky load on the roof dramatically changes the aerodynamics and center of gravity of the car. Sailing increases significantly, which is especially noticeable when overtaking trucks or when there is a strong side wind. The steering wheel becomes heavier, and the car's reactions to turns are more sluggish and inert. Brakeway It also increases due to increased mass and aerodynamic drag.
The recommended speed with a boat on the roof should not exceed 90 km / h. Exceeding this limit dramatically increases the risk of demolition of the cargo by a gust of wind or destruction of the anchorages due to vibration. In addition, at high speeds, fuel consumption increases significantly - it can increase by 20-30% depending on the shape of the boat and the quality of its stowage.
When maneuvering, especially in parking lots with height limiters or entering a garage, always remember the dimensions. A boat on the roof adds 40 to 60 cm of height to the car. It is useful to stick a noticeable sticker on the torpedo, a reminder of dimensions, so as not to forget about the "addition" after a long stay.
- 🐢 Speed mode: Keep within 80-90 km/h for safety.
- 🛑 Distance: Increase the distance to the transport ahead.
- 🔄 Maneuvers: Avoid sharp changes and sharp turns.
Safe speed with a boat on the roof is not only compliance with traffic rules, but also a guarantee that fasteners will withstand the load without breaking.
FAQ: Frequently asked questions
Can I transport a boat on the roof with an engine installed?
Technically, it's possible if the trunk is weight-bearing, but it's not recommended, because the motor creates additional sailing, vibration and risk of damage to the cylinders or bodywork by lower unit, and it's better to remove the motor and move it separately in the cabin or trunk.
How often should you tighten your belts on the way?
The first check is made 10-15 kilometers after the start of the movement, and then it is recommended to check the tension every 100-150 km or after each long parking, as the materials can shrink or stretch.
Is it dangerous to wash a car with a boat on the roof?
Automatic brush washers can break PVC or break the mounts. If you need to wash the car, take the boat off. If that's not possible, choose only high-pressure washers without contact brushes and be extremely careful.
Do I have to put the boat down before transportation?
It is not necessary to completely descent, and even harmful to the shape, it is enough to reduce the pressure to 0.15-0.18 atm (a little below the working one) to compensate for the expansion of air when heated in the sun and reduce sailing, while maintaining the rigidity of the structure.
