Choosing boat redans is a task that requires attention to detail, which not only improves the performance of the vessel, but also affects safety, economy and comfort while driving. However, the market offers dozens of options, from budget plastic models to professional aluminum structures with a hydrodynamic profile. How do you make the mistake of buying the exact redan that will suit your boat?
In this article, we will discuss all the key aspects of the selection of rents From materials and sizes to installation features, you'll learn which models are best suited for PVCWe will also analyze prices, compare popular brands and give practical installation tips.
What are the Redeemers and why do they need them on a boat?
Redeemed (or) plate-stove) These are horizontal protrusions on the bottom of the boat that optimize its hydrodynamic properties. Reduced water resistance when driving at high speedsWithout redans, a boat with a 15-30 hp engine can burrow its nose into the water, losing controllability and stability.
In addition, the rented performs several additional tasks:
- 🔹 Improved manageability - the boat is easier to planing and better holds the course.
- 🔹 Reduced spray Properly installed redanes reduce the splashing of the sides.
- 🔹 Prevention of “tossing” This is especially important for fishermen and tourists.
- 🔹 Increased load capacity A boat with reds can take on board more passengers or cargo without loss of driving performance.
It is important to understand that redanes are not a universal solution, for example, for slow-moving boats (up to 10 km / h), they can be useless, and in some cases even impair maneuverability. 20 km/h and higher.
⚠️ Attention: Some owners install the reds on boats with low-power engines (5-10 hp), waiting for miracles, in reality, such vessels simply will not be able to go to the planing, and the reds will become extra ballast.
Types of Redan: What are and how are they different?
All the services can be classified according to several criteria: fabrication, construction and fixationLet's look at each type in detail.
1. By material
- 🛡️ Aluminum The most durable and durable, suitable for metal boats, weight from 1.5 to 5 kg (depending on size).
- 🧊 Plastic (PVC, polyethylene) They're lightweight and cheap, but they're less resistant to mechanical damage, and they're often used on PVC boats.
- 🔧 Composite (glass plastic, carbon fiber) They combine lightness and strength, but they cost more. They're popular with professional fishermen.
- 🫙 Rubber (inflatable) - a temporary solution for PVC boats, attached to Velcro, suitable for testing before buying stationary sedans.
2. By design.
- 📏 Flat. - the simplest option, suitable for calm water (lake, river without a strong current).
- 🌊 Steps (multiple) improve the output for planing, but require accurate adjustment in height.
- 🔄 Regulated - allow you to change the angle of attack depending on the load and swimming conditions.
3. By method of attachment
- 🔩 Bolt-bolt A reliable method for aluminum boats, but requires drilling holes.
- 🧲 Magnetic - quick-removal mounting, but is suitable only for metal surfaces.
- 🧵 Adhesive (on double-sided scotch or epoxy) It is used for PVC boats, but less reliably at high loads.
| Type of redan | Advantages | Deficiencies | Average price (per pair) |
|---|---|---|---|
| Aluminum flat | Durability, durability, suitable for engines 15+ hp | Heavy plastic, require anti-corrosion treatment | 3 500 – 8 000 ₽ |
| Plastic stepped | Lungs, do not rust, simple installation | Less resistant to shocks, can crack in the cold | 2 000 – 5 000 ₽ |
| Composite regulated | Optimal hydrodynamics, corrosion-resistant | High price, complexity of installation | 10 000 – 25 000 ₽ |
| Rubber inflatables | Mobility, do not require drilling, cheap | Short-term solutions can be deflated | 800 – 2 500 ₽ |
How to choose a boat for a specific boat?
There are no universal redans – their parameters must correspond to the boatlike, motor-power and operating conditionsHere are the key selection criteria:
1. Size and shape of the boat
For PVC boats up to 3.5 m will fit the width 20-30 cm length 50-80 cmFor aluminum boats from 4m It is better to choose models from 30cm wide and 100 cm Long. Cases. (for example, PVC boat Frigate-330) often require individual fitting.
Engine power
- 🛥️ Do
10 hpNo need for redundancies or only flat plastic. - 🚤
10 to 25 hp.- aluminum or composite step. - ⚡
30+bhp- adjustable multi-row redanes with reinforced fastening.
Conditions of navigation
For rivers with fast currents and waves are suitable high-endAnd for standing water, flat water, if you walk in shallow water a lot, go with the models. rounded-edgeTo avoid damage when hitting the bottom.
Check the maximum load of your boat |Clarify the material of the bottom (PVC, aluminum, fiberglass) |Determine the power of the engine |Measure the width and length of the installation area |Consider the type of reservoir (river, lake, sea)->
⚠️ Attention: Some boat manufacturers (e.g., boat manufacturers) bark or Nissan) prohibit the installation of redans on their models due to the risk of loss of warranty.
Top 5 manufacturers of redans: comparison and reviews
In the Russian market, several brands are leading, whose redans have earned the trust of fishermen and tourists. FishHunting and BoatMaster) and have compiled a rating:
- RedanPro (Russia) - aluminum redanes with anti-corrosion coating. RedanPro Alu-300 (80 cm long, 2.3 kg weight). Pros: boat-fitting Finger and Kazanka. Cons: High price (from 7000 ).).
- BoatTech (Ukraine/Russia) - plastic and composite redan. BoatTech Carbon-2 It is often praised for its lightness (1.8 kg) and strength. Price: 5 500–6 000 ₽.
- Aquamaster (Russia) - budget redundants for PVC boats. Aquamaster Standard (plastic, 2,200.) is suitable for motors up to 15 hp.

- forward (Russia) - rented for professional boats. Forward Diamond (aluminum, 9000 RUB) is used in water-motor sports competitions.
The most common complaints about cheap models are: effusion (for plastic redans) and corrosion There are almost no complaints in the premium segment, but the price may be higher than that. 15 000 ₽.
How to distinguish a fake from the original?
Original reeds RedanPro and HydroGlide have:
(1) Laser engraving of the logo (not a sticker!).
(2) Certificate of conformity complete.
(3) Hologram package.
Counterfeit products are often sold without instructions and with rough welding seams (in aluminum models).
Self-installation of redans: step-by-step instructions
Installation of redans can be entrusted to specialists (cost of work - from 1 500 ₽), but with the tools, it's possible to do it yourself. Let's take an example of an aluminum boat with a bolt mount.
Tools required:
- 🔧 Drill with drills on metal (
3-4 mm). - 🔩 A set of bolts with nuts and washers (stainless steel!).
- 🧴 Sealer for boats (e.g., waterproofing) Sikaflex-291).
- 📏 Roulette, marker, level.
Step-by-step process:
- Markup. Apply the redeemed to the bottom (retreat).
30-50 cmAnd then you'll see the PVC boats, and you'll need a stencil. - Drilling. Drill holes in the boat and redanas (the diameter of the drill should be on the boat).
0.2 mmless than the diameter of the bolt. - Sealing. Apply the sealant to the mounting places and on the plate itself around the perimeter.
- Installation. Then, put them in the snare without snatching them.
4-6 Nm.). - Testing. Lower the boat and test it at low speeds, and if you're vibrating or sucking air, reset it.
Before drilling the holes, stick to the place of future fastening of the tape - this will prevent the drill from slipping through aluminum or PVC.
For PVC boats, the process is simplified: reds are attached to double-sided tape 3M VHB But it's less reliable, because when you hit an obstacle, the reds can come off.
⚠️ Attention: If you are installing a reed on a boat with keelMake sure they don’t cover it more than 30%Otherwise, the handling will deteriorate and the risk of yaws will increase.

The best deals usually appear at the end of the season (October-November) when stores sell off leftovers.
Frequent errors in the selection and installation of redans
Even experienced boaters sometimes make miscalculations that lead to poor performance or breakdowns, and here are the most common mistakes:
- Wrong size. Too wide redans create excessive resistance, and narrow redans do not give effect. Decision: the width of the redanes should be
20–30%from the width of the boat. - The sealant-free installation. Water penetrates under the anchorages, causing corrosion (in aluminum boats) or detachment (in PVC). Decision: use sealer (for example, BoatLife).
- Ignoring the balancing act. Redans shift the center of gravity, and if you don't adjust the distribution of the cargo, the boat will tilt. Decision: Move the battery or load closer to your nose.
- Fastening on bent bolts. Uneven bolts create tension in the material, which leads to cracks. Decision: Use only new stainless steel bolts.
- Installation on a boat with a damaged bottom. Cracks or dents under the redans accelerate their destruction. Decision: Repair the underbody before installation.
Another typical problem. engine incompatibilityFor example, if you install a step-wielded redan on a motorboat. 5 hpInstead of improving speed, you will get:
- 🔴 Increased fuel consumption by
15–20%. - 🔴 Vibration at high speed.
- 🔴 Risk of damage to the transom when hit by a wave.
How to check the quality of the installation?
After installation, perform a test run:
(1) Accelerate the boat to maximum speed, there shall be no nose toss.
(2) Turn the steering wheel sharply; the boat must obey without delay.
(3) Check if the air is sucking under the redanes (sign - whistle or bubbles).
If at least one point is not fulfilled, an adjustment of the angle or position of the redans is required.
FAQ: Answers to frequent questions
Can I install the reds on an inflatable boat without a hard bottom?
Technically, yes, but the effect will be minimal. Redans are only effective on hard surfaces (aluminum, PVC with floorboards) on a fully inflatable boat (e.g., a squirrel). Bestway or Intex) they will not improve driving performance, but will only add weight. Except for special inflatables, but they are suitable only for engines up to the limit. 5 hp.
How many redans do you need to install: one or two?
The optimal amount is two-residenceOne redan (center) can cause imbalance and "steer" the boat aside. 1.2 mwhere one central redan is sufficient.
How often should I check the mounting of redans?
It is recommended to inspect the bolts and sealant before each release to the water, and after:
- 🌊 Wave navigation (wave height > 0.5 m).
- 🪨 Impacts on underwater obstacles.
- ❄️ Keeping a boat in winter (sealer can crack from frost).
With intensive operation (more than 20 outputs per season), bolts should be tightened once a month.
Can you make a handmade handmade?
Yes, but only if you have experience with metal or plastic, and for homemade redans, they often use:
- 🔧 Aluminum sheets thick
3.5 mm. - 🧊 PVC plates (
10-15 mm). - 🛠️ Epoxy resin with fiberglass reinforcement.
The main risk is fluid-formIt's a squirrel that, instead of improving speed, will create additional resistance, and if you're in doubt, you'd better buy ready-made redance.
Do the redeemeds affect the registration of the boat in the GIMS?
No, the installation of redans does not require re-registration of the vessel, as they do not change the data-sheet specifications However, if you modify the boat drastically (e.g., installing an extra keel), it may require changes to the boat's ticket.
