Boat tuning Progress 4: from hull rework to comfort

Legendary Progress 4 For decades, it has been one of the most popular aluminium boats in domestic waters, a reliable, time-tested design that, however, has its own design features that require refinement for modern comfort levels. Owners often face the need to reduce noise levels, improve stability and add convenience for long fishing or cruising.

Competent Boat tuning Progress 4 It allows you to turn a utilitarian can into a full-fledged family boat, the main areas of modernization are the installation of the deck, redevelopment of the cockpit, strengthening the transom and improving driving performance. It is important to understand that any changes in the design of the boat require a balanced approach, so as not to disturb the centering and unsinkability.

In this article, we will discuss in detail the proven solutions for the improvement of the case and interior. You will learn how to organize the space correctly, what materials are best used for paiola and how to install additional equipment without the risk of damage. aluminum-alloy Duraluminia.

Analysis of the initial design and modernization plan

Before you start to take up tools, you need to clearly understand the weaknesses of the basic equipment. Progress 4 It has an open cockpit zone, which, when you're excited, causes water to splash and accumulate at the bottom, and the regular banks don't provide the comfort they need to be on the water for a long time, and the work plan usually includes building a solid deck, installing rundooks, and upgrading the control system.

The key is calculating the weight load, installing heavy equipment like powerful equipment. boat-engine Or massive rundoos, which can shift the center of gravity, and that has a direct impact on the differentiation and, as a result, on speed and efficiency, so a tuning project always starts with drawings and pre-weighting all the elements that are planned for installation.

⚠️ Attention: When drilling holes in the housing for installation of fasteners, be sure to treat the edges of the drill and the holes themselves with an anti-corrosion composition, even if stainless fasteners are used. Contact of dissimilar metals in salt or fresh water can cause electrochemical corrosion.

Modern safety requirements require that reliable struts and awnings be installed. The regular mounting positions are often not strong enough to fit a full-fledged windshield running awning, so many owners prefer to make custom stainless pipe brackets that attach to the power elements of the frames.

Manufacture and installation of a solid deck

One of the most time-consuming but useful operations is to replace the regular removable paioles with a single design. A solid deck not only gives the boat an aesthetic appearance, but also significantly improves safety, eliminating the risk of leg failure between banks.

The process begins with the exact removal of patterns from the bottom of the boat. Progress 4 It's not perfectly flat, it has a bilson and zygomatic bends, and it's made to fit these irregularities, leaving small gaps at the sides for water runoff, and it's always soaked in epoxy and pasted with glass or multi-layered yacht varnish to protect against moisture.

• 🛠️ For attaching paioles to the sides, it is better to use removable aluminum brackets, which will allow you to dismantle the floor if necessary for drying the boat.
• 🛠️ Between the floorboards and the aluminum bottom, it is recommended to lay a layer of vibroisolating material, for example, foil foil, which will reduce noise.
• 🛠️ All wooden structural elements must be treated with antiseptics to prevent rotting in high humidity conditions.

It is important to provide hatches or removable sections in the deck to access the bow and to allow water to be pumped out of the hold. Often a large hatch is made in the front to accommodate the anchor box and batteries, which allows for rational use of space and unload the cockpit.

The finished deck not only improves ergonomics, but also adds stiffness. However, it is worth remembering that excess mass at the bottom can adversely affect the performance of low-power engines. Therefore, when choosing material for floorboards, you should look for a balance between strength and weight, preferring modern composites or high-quality aviation plywood.

Organization of space: handbags and seats

Comfort on the water is impossible without comfortable seats and storage spaces. Progress 4 Tuning involves the installation of stationary or removable hazelnuts, which serve as both seats and sealed drawers, and the location of the hazelnuts along the sides frees the central part of the cockpit for movement.

When designing furniture, it is important to consider the height of the seats. The optimal height is 40-45 cm from the floor. Runduks are made of the same material as paioles, or use ready-made plastic boxes mounted in a wooden frame. Runduk covers should have reliable hinges and latches so that when a sharp roll things do not fall overboard.

Type of seat	Basic material	Upholstery	Advantages
Stationary runduk	Plywood/Aluminum	viniliskoge	Maximum storage capacity, high strength
Removable chair	Plastic.	Fabric/Oxford	Mobility, ease, ability to fold
The transom bench	Aluminum profile	Foammate	Saving space, convenient for the passenger at the motor

For upholstery seats, it is best to use marine viniliskozh, which is resistant to ultraviolet and salt water. Under the upholstery, a layer of foam 3-5 cm thick is laid. Seats are fastened to the floor or sides through powerful brackets to prevent them from shifting when hitting a wave.

You can also put soft backs on the front wall of the nose or on the transom, which will turn the hard can into a full-fledged chair with a backrest, which is critical for long transitions. Remember to leave access to the fuel tank and drainage holes.

Modernization of the transom and installation of the motor

The regular transnet Progress 4 But current trends require more powerful engines to go full-load plane, and transom amplification is one of the most important operations, because crew safety depends on it.

To reinforce the inside of the transom is attached an additional plate of stainless steel or duraluminium thickness of 4-6 mm. The fastening is carried out by bolts through the body using a sealant, which allows you to distribute the load from the motor over a large area and prevent deformation of the transmolatory board.

⚠️ Warning: Never exceed the maximum power allowed on the boat's passport, even after the transom is reinforced, which can cause the structure to break at full speed and roll over.

And you also have to consider the installation of transom wheels, which allows one person to easily move the boat down a slip or a shore, and the wheels are attached to a frame that is then fixed to the transom, and when you're on the trunk, the wheels go up and don't interfere with the movement.

• ⚓ For reliable fixation of the motor, use special transom mounts with rubber shock absorbers.
• ⚓ Install a fuel compartment with ventilation and access to replace the tank, observing fire safety regulations.
• ⚓ Consider a system for fastening the fuel hose to exclude its rubbing on the metal edges.

An important element is the tiller-extension (tiller extension) or the transition to remote control. Progress 4 It's very common to have a steering wheel close to the transom, which is not always convenient, and if you have a console or even a simple steering wheel rack, you can see and handle a lot more.

Improvement of driving and seaworthiness

Project aluminum boats Progress They're very stable, but they're often criticized for being stiff and slapping their noses on the wave, and one of the most effective ways to solve this problem is to put a hydrofoil on a lower unit motor or flow deflector, which lifts the boat's nose when it's going out for glides and stabilizes the course.

Another method is to install inflatable tubes on the sides, which not only increase the buoyancy reserve, which is critical for safety, but also extinguish the shocks against the wave, making the stroke softer, and also protect the sides from scratches when mooring and allow safe mooring to unequipped shores.

To reduce the noise and vibration that inevitably arise when the motor is running on an aluminum body, vibration insulation is applied, bitumen-vibration materials are glued onto the inner surface of the bottom and sides, and a noise-absorbing layer is on top of them, which makes the sound of the waves sound deaf, less tedious.

And windscreens, too, are very important, and even a small glass in front of the steering wheel can be very comfort-promoting, protecting against oncoming airflow and splashes, and the glass must be removable or foldable for easy transportation and storage.

Electrical equipment and navigation

Modern fishing or cruising is unthinkable without navigational devices and lighting. Installing sonar, GPS and running lights requires proper electrical wiring. All wires must be stacked in corrugated hoses and securely secured to prevent damage to the insulation.

To power the appliances and start the engine (if electric or preheating is required), additional batteries are needed, placed in special sealed boxes in the bow for balancing the boat, and the boxes must have ventilation to remove the gases generated during charging.

Connection scheme of the onboard network:
1. Main mass switch ("Button")
2. Safety lock (30A) -> Battery
3. a safety locking box for each appliance
Grounding of the sub-point on the body (through a bolt with stripping to metal)

Be sure to install running lights according to the rules of the PPF (Inland Waterways Rules), white top light, red and green side lights should be visible from the appropriate directions. For night fishing, a work area lighting fixated on a tent or console rack will not be superfluous.

How to protect electricians from water?

All connections are made in sealed IP67 switch boxes. Use adhesive-coated shrink to insulate the twists. Use wires above the level of possible flooding of the cockpit, attaching them with clamps every 30-40 cm.

The final step in electrification is to install USB sockets to charge your gadgets and LED tapes inside the rundoos to find things in the dark, so you don't overload the grid and keep track of the battery status.

Finishing and care of the boat

Once all the technical work is done, it's time for aesthetics. Progress 4 You can paint it brightly using special aluminium enamel, or you can paste it with vinyl film, and not only does it improve the look, it also creates an extra layer of corrosion and scratch protection.

Inside the cockpit, a sliding coating is often used, which can be a special quartz sand varnish, rubber mats or a self-adhesive film with an abrasive spray (anti-slip), and the safety of moving on the wet deck is the number one priority, especially if there are children on board.

• 🧼 Wash the boat regularly with fresh water after each exit, especially if you have been swimming in salt water.
• 🧼 Once a season, check the condition of rivets and welds for cracks or oxidation.
• 🧼 Lubricate the moving parts of the mechanisms (hinges, locks) with silicone lubrication to prevent acidification.
