Comfort on the water is not just a bonus, but a prerequisite for long fishing or family vacations. Standard cans, which come with most budget boats, are often too low, rigid and ergonomic. boat-stand It is one of the most popular elements of tuning, which owners install in the first place.
This design allows for standard car seats or specialised sea seats with armrests, which drastically changes back fatigue levels after 4-6 hours on a river or lake, and the aluminum alloys used in manufacturing are highly corrosive, which is critical for aggressive aquatic environments.
In this article, we will discuss in detail what types of racks exist, how to correctly calculate their height for your height and the features of installation on different types of bottom. You will learn about the nuances that beginners often miss when trying to upgrade their boat on their own.
Why you need a separate rack: advantages over regular banks
The regular cans (crossbars) in boats, whether PVC or metal, primarily serve as a side-stripping function, rarely exceeding 15-20 cm from the floor, which causes a person to sit, effectively squatting. Seat rack raises the level of landing to 35-45 cm, providing the correct angle in the knee joints and removing the load from the lower back.
In addition to ergonomics, using a separate support gives mobility, and if the bank is fixed rigidly or inserted into the loops, then it is impossible to move it. Modular rack This makes it easy to change the position of the chair, so you can sit closer to the nose to control the engine or move to the side to throw gear, and this is especially true for flat-bottomed boats, where space is used as efficiently as possible.
The important thing is that you can have a soft chair with a back, a hard chair, or even a snack table on the same platform, and that flexibility makes a utilitarian boat a full-fledged recreational boat. Aluminum structures weigh a little, so the overall weight of the vessel doesn't increase much.
- 🚤 Significant reduction in fatigue of the back and legs with prolonged exposure to water.
- 🛠️ The ability to quickly remove the seat to any point of the cockpit.
- 💺 Compatible with car seats, which allows you to use the usual ergonomics.
- 🌊 Resistance to corrosion and mechanical damage due to the properties of the alloy D16T or AD31.
⚠️ Warning: Installation of a rack too high without a corresponding shift in the center of gravity can make the boat less stable. Do not exceed the height of the structure by more than 50 cm from the floor without consulting the engineer or manufacturer of the vessel.
Types of structures: collapsible, welded and adjustable models
The water accessories market offers several basic options for the performance of the supports, the choice depends on whether you plan to store the boat in its assembled form or will regularly disassemble and transport it in the trunk of a passenger car.
Welded racks They are monolithic structures, most often in the form of the letter "T" or "P." They are characterized by maximum rigidity and durability, because they lack mobile connections that could loosen. However, their dimensions require a spacious storage space or permanent stay in the boat.
Collapsible models consist of several segments connected by bolts or pins. Adjustable height And this is a key feature of these systems, which is that you can change the level of planting depending on whether you have a tall child or an adult sitting next to you, and that makes them ideal for family use.
Separately, the combinations, where the vertical pipe is inserted into the bottom of the base, are a compromise between the reliability of the welded structure and the compactness of the collapsible structure, and the base is usually attached to the floor of the boat through special flanges or welded pens.
Comparison of materials: Aluminum vs. Steel
Aluminum alloys (D16T, AD31) are lighter and do not rust, forming only an oxide film. Steel is stronger, but requires a perfect paint coating, since any scratch will lead to rapid corrosion in salt water.
Material selection and compatibility with boat type
The main material for making quality racks is aviation aluminum. It has the optimal ratio of strength to weight. When choosing, pay attention to the thickness of the profile wall: 2 mm is enough for a single seat, but if you plan to install it, you can use it for a single seat. double-chair or a seat for two, it is better to take a profile with a wall thickness of 3 mm.
For PVC inflatable boats, the absence of sharp edges and barbs on metal is critical. Any roughness when rolling or vibrating can damage the balloon. So all the ends of the pipes must be muffled with plastic or rubber plugs. Metal boats (Cossacks, fireworks) are softer, but anti-corrosion treatment is still necessary.
There are universal models with a wide base that do not require floor drilling. They are held by their own weight and friction, but their reliability is lower than that of fixed options. For active activities, such as catching large fish, only rigid fixation is recommended.
⚠️ Attention: When installing a rack on the inflatable floor (NDB), the use of metal pens with sharp edges is unacceptable. Be sure to use additional pads made of dense rubber or linoleum under the support.
Installation instructions: step-by-step installation on the boat floor
The installation process requires precision and a minimum set of tools, and the main task is to ensure a reliable mount that will withstand dynamic stresses during the turbulence and sharp rolls of the vessel. Before starting work, make sure that the boat floor is clean and fat-free.
First, you make the markings. You determine the optimal seating position by sitting on a temporary support and checking the ease of control of the engine or rowing. Note that the rack should not interfere with the operation of the bumper or rest on the side when rolling.
If you use a bolt-mounted model, you need to drill holes in the floor. For aluminum boats, this is done with a metal drill, for PVC, carefully so as not to damage the bottom layer of the balloon (if the floor is inflatable, you can not drill, only stick the pentacles).
☑️ Checklist for installation
The fasteners must be made of stainless steel (A2 or A4). Ordinary ferrous metal will rust in one season. Bolt hats and nuts must be fitted with wide washers to distribute the load. If the floor is metal, the holes on the back side are also desirable to be treated with anticores.
Sequence of action:Mark the holes with a marker.
2. drill holes with a drill of smaller diameter, then drill to the desired.
3. Treat the edges of the holes (marking).
4. Apply the sealant to the rack assembly area.
5. Roll the rack with bolts, evenly tightening the nuts cross-cross.
Comparative table of specifications of racks
To make it easier for you to decide on the choice, we have prepared a summary table of the main parameters of various types of designs presented on the market.
| Parameter | Welded monolithic | Collapsible (bolted) | Adjustable (telescope) |
|---|---|---|---|
| Structure weight | Medium (1.5 - 2 kg) | Low (1.0 - 1.5 kg) | Tall (2.0 - 2.5 kg) |
| Difficulty of installation | Minimum (ready) | Medium (assembly) | High (setting) |
| Dimensions folded | It doesn't add up. | Compact | Average. |
| Maximum loading | Up to 150 kg | Up to 120 kg | Up to 100 kg |
| Price. | Low/Mediocre | Medium | High. |
As you can see from the table, welded models are best suited for continuous operation on the same boat, they are simpler and more reliable. If you change boats often or carry parts in a backpack, then you can use them in a backpack. foldable It's preferable.
When buying an adjustable rack, check the quality of the height retainers. Cheap plastic latches in the cold or under load can break, leading to a sudden folding of the structure.
Operation and care of aluminum structures
Aluminum is a very unpretentious material, but it also requires attention, especially after contact with salt water. The oxide film that protects the metal can eventually break down under the influence of aggressive media or mechanical friction of sand.
After each foray into the water, especially at sea, it is recommended to rinse. aluminum-stack It'll wash away the salt and dirt that can cause spot corrosion, and once a season, it makes sense to take off your seat and inspect the mountings for backlashes.
If you notice that the bolts have started to scroll or there is a shakyness, don't ignore this. The vibration on the water is very strong and can quickly unscrew even well-tightened joints. Use a thread lock (anaerobic sealant) when reassembling.
⚠️ Warning: Do not use abrasive powders or hard metal brushes to clean aluminum racks. This will damage the protective oxide layer. Use a soft sponge and neutral detergents.
Regular fresh water rinsing and checking the bolt tightening twice a season will extend the life of your rack to 10 years or more.
FAQ: Frequently asked questions
Will an aluminum rack withstand a 120 kg person?
Yes, high-quality racks from the profile D16T or AD31 with a wall thickness of 2 mm are designed for a load of up to 150 kg or more.
Can I install a car seat on any rack?
Most racks have a standard landing pad or sled adapter, but the size of the seat mounts of different brands may vary, so a transition plate may be required.
What height to choose for comfortable fishing?
The optimal height is considered, at which the foot is completely on the floor and the angle in the knees is about 90-100 degrees. For most people, it is 35-40 cm from the level of the boat floor.
Do I need to paint an aluminum rack?
You don't need to paint unless you care about color, anodized or polished aluminum looks great and is protected by a natural oxide film, and paint can only hide the defects that appear.
Where to buy a quality rack?
It is best to purchase specialized boating stores or order from aluminium craftsmen. Avoid cheap Chinese counterparts with thin pipe walls.
