Overview of the Cobalt R4 and Its Place in Recreation
The Cobalt Boats R4 is a versatile runabout, made with attention to detail for families and friends who want comfort, durability, and straightforward enjoyment on the water. At 24’3” long and with a beam of 8’6”, the R4 sits in a sweet spot: it’s easy to trailer and fits in many residential storage spaces, but it’s also large enough to handle a good-sized group. The layout is open and inviting with a spacious bow, a deep cockpit, and an extended swim platform. The R4 design strikes a balance between looking good and being useful. The appearance is sleek, with flowing lines and a low-profile deck, giving it a contemporary look without sacrificing headroom or seating space.
The R4 is built with families and groups in mind, allowing up to 14 passengers to join each trip. This means you can bring along friends for a day out, host a picnic on the water, or simply spread out and relax. The cockpit design includes wide walkways so people aren’t climbing over seats or squeezing past each other, which minimizes accidents and makes everyone more comfortable. Storage is built-in under almost every seat and the in-floor ski and board compartment holds everything from life jackets to water skis and inflatables. The rear swim platform is finished for comfort and safety, using soft, non-slip SeaDek material and an easy-to-use ladder so everyone can get in and out of the water safely.
Engine Options and Smooth Ride
The R4 is often rigged with either a Volvo Penta or a MerCruiser stern drive system, known for their reliability and strong performance. Horsepower options commonly range from 280 HP up to 350 HP, giving owners flexibility based on their needs. The engine is mounted mid-ship and deep in the hull, which helps balance the boat for a consistent ride no matter how many people or how much gear is on board. The deep-V hull design is effective in cutting through wakes and chop, giving the R4 a smooth, dry ride across most types of inland or coastal waters.
The hull shape and strake placement make the boat easy to turn, steady at idle, and stable when passengers move about. This design means comfortable trips even if there’s a breeze or boat traffic stirring up the water. The 50-gallon fuel tank provides long range for full days exploring, and at moderate speeds, fuel efficiency is good for the class. People on board will notice less vibration, less noise, and steady handling even as conditions change throughout the day.
Passenger Comfort and Seating
Throughout the boat, Cobalt uses premium foam and marine-grade vinyl for every seat. These are soft, supportive, and resist mildew and sun fading. The captain’s chair swivels, slides fore and aft, and has a flip-up bolster for better visibility or taller drivers. The co-captain seat mirrors the same comfort and control. In the bow, seats are extra deep with angled backrests for lounging or stretching out. Stainless steel grab handles and cupholders are easy to reach, so people feel secure and have places for drinks and snacks.
The cockpit lounge wraps around most of the open space. Cushions are removable for easy cleaning and the seat bases are ventilated to dry out quickly if they get wet. There are several seating configurations possible, with the rear bench able to transform into a sunpad or have the middle section lifted for a walk-through or transom access. The high sides of the boat—known as freeboard—mean everyone rides deeper in the vessel, which adds to both comfort and safety.
Storage and Layout Details
The Cobalt R4 is all about practicality and smart use of space. Under-seat storage is found nearly everywhere: bow seats, cockpit benches, and even under the sunpad. The in-floor locker is full-length and vented, with a secure latch for wakeboards, skis, towropes, and floaties. In the main cockpit, side pockets hold smaller items like sunscreen, towels, or flip-flops. There is also a port console glove box that is lockable to secure valuables like wallets and phones.
A 50-quart cooler fits in its own compartment, and there’s built-in trash storage so keeping the area neat is simple. For wet gear like swimsuits and towels, the swim platform includes a dedicated locker, making sure wet items are kept out of seating areas. Thoughtful placement of storage areas means that even with a full crew, the deck remains uncluttered.
Controls and Technology
The R4’s helm combines analog and digital controls, blending familiarity with modern function. The main display is readable in full sun and shows speed, RPM, engine diagnostics, depth, and trim angle. The Bluetooth stereo has speakers positioned throughout the boat and a set of controls near the swim platform, so music can be managed from the water or inside the cockpit. Multiple USB ports make charging phones or tablets easy.
For navigation, the dashboard allows for optional GPS/chartplotters, giving the captain the tools needed for exploring or vacationing in unfamiliar waters. LED lights are installed for twilight and night use, with both navigation lighting and accent illumination in storage spaces and cupholders. The captain’s seat adjusts for both height and distance, helping make long days at the wheel more comfortable. Toggle switches are simple, waterproof, and clearly labeled so there’s no confusion, even when underway.
Entertainment on the Water
Whether your group prefers quiet sunsets or high-energy watersports, the R4 has features to match. The swim platform is the central gathering spot, with a ladder that is angled and easy for swimmers of all ages. The sunpad over the engine hatch offers space to dry off or lounge in between swims. Cupholders, speakers, and a walk-through transom make the rear deck social and functional.
Inside, removable cockpit tables can be set up in both the bow and main seating area. These tables hold food, drinks, and card games, then stow away quickly and securely. If the weather calls for more shade, a bimini top covers most of the cockpit, keeping the sun off guests and reducing fatigue during hot days. With built-in coolers and drink holders, it’s easy to keep cold drinks and snacks within reach for the whole day.
Water Sports and Recreation
For people who enjoy action, the R4’s deep-V hull and strong engine choices mean excellent pulling power for water skiing, tubing, and wakeboarding. The large in-floor locker holds multiple boards and ropes, so you’re never short on equipment. The aft bench seat can be raised to spot for the person in the water, and the aft-facing seat on the transom is a safe and comfortable place to watch the action. The R4 tracks well for towing, keeping the wake clean and making turns smooth so even new drivers can learn quickly.
There’s also an option for a built-in ski tow pylon which makes hooking up a rope safe and fast. With quick access to the water from the platform and swim ladder, riders can rotate through activities all day. When everyone’s ready to take a break, the large sunpad and cockpit benches offer space to stretch out and recover.
Safety for All Ages
Safety is always on the list for R4 buyers. The boat’s deep cockpit keeps kids and pets securely inside. Non-slip flooring extends from the bow through the cockpit and onto the swim platform. Handrails are easy to find near every seat, and the windshield blocks wind while underway. Navigation lights are bright and mounted high for visibility in low light.
There’s room for a throw cushion, life jackets, and emergency equipment in easy-to-reach lockers. Stainless steel hardware means everything from cleats to anchor mounts stays secure, even after years of use. An automatic bilge pump clears out any water that gets in, and dual batteries are available for electrical peace of mind. The R4 makes it easy to rig safety lines, tow ropes, and even a tow flag for skiers so drivers can focus on fun instead of struggling with gear.
Quality Construction and Materials
Cobalt’s build quality is reflected in every part of the R4. The hull uses hand-laid fiberglass for maximum strength and minimal flex. Structural support comes from a full-fiberglass stringer system, which resists rot, mold, and water damage. Areas prone to wear are reinforced, from the bow eye to the swim platform. Stainless steel through-bolted hardware stands up to repeated stress and doesn’t corrode like aluminum or zinc. Gelcoat exterior surfaces use UV inhibitors to stay bright and glossy after years in the sun.
Inside, vinyl seating is marine-grade, resists tears, stains, and sun damage, and can be cleaned with simple soap and water. Touch points such as cup holders, grab rails, and hinges are all metal or durable composite, not thin plastic. Wiring is routed for easy access, protected from moisture, and labeled for convenience during routine checks.
Clean, Low-Maintenance Experiences
Every part of the R4 is made to be user-friendly and simple to maintain. Vinyl-coated flooring resists stains and is easy to sweep or wash. The engine compartment opens wide, and the single prop, belt, and battery are all within reach. Drain plugs are positioned for effective draining on the trailer, and self-bailing decks help keep water out of the cockpit. Cushions and storage bins snap out for cleaning or drying.
Routine checks, such as topping off fluids, inspecting belts, or checking bilge pumps, are straightforward and described in plain language in the owner’s manual. Stainless and composite hardware doesn’t rust or corrode in fresh or saltwater. Because so much of the boat is built for weather resistance, less time and money is spent on cleaning and repairs.
Features for Quiet or Active Days
You can use the R4 for just about any type of outing. For quiet time, anchor out and enjoy the sunpad, cockpit shade, and built-in sound system. For a faster pace, load up with friends, toss water toys in the in-floor locker, and tow tubes or skis with plenty of pulling power. There’s enough open space for kids to play games, for adults to relax with a book, or for everyone to gather for a meal using the removable tables.
Because the R4 has both bow and aft seating, users can split into smaller groups for different activities—some can lounge up front, while others stay near the swim platform and ladder. There’s room for a grill or portable stove if you like to have a cookout on the water. And with cupholders spaced throughout, no one needs to worry about spills or missing their drink while underway.
Weather Adaptability
The R4 is made for changing weather. The bimini top can be set up in minutes, providing shade from harsh sun but also adding a layer of protection against light rain. The large windshield with walk-through access helps block wind and spray, making it more comfortable during breezy days. For colder outings, seat cushions are thick enough to offer insulation, keeping passengers warm. If the weather clears, the bimini folds down out of the way, opening up deck space.
All consoles and controls are sealed against splashes, so you don’t have to worry about rain shutting down the electronics. The non-slip deck surface prevents accidents if it gets wet, letting guests continue enjoying the day without concern about slipping or losing balance.
Family-Friendly Features
The R4’s versatility shines for families. The high freeboard keeps little ones and pets safe, and the deep cockpit cuts down on wind. Boarding from the dock or swim platform is low and easy, which can help older adults or younger kids get on and off safely. Seats are padded for comfort, with no sharp edges or exposed hardware. Table mounts are sturdy and locked in place so food, drinks, and games stay put.
There’s cold storage for drinks and snacks, lockable storage for valuables, and washable surfaces from front to back. The engine placement reduces exhaust smell and noise in the seating areas, so children can rest, nap, or play without constant disruption. There’s even storage under the cockpit sole for extra towels, sunscreen, and water toys, helping keep the main space clutter-free.
Entertainment Technology Details
The stereo system in the R4 offers Bluetooth pairing, making it easy to stream music from any smartphone or tablet. Speakers are spaced so sound fills the boat without being overwhelming in any single area. Volume controls can be operated at both the helm and swim platform, so no one needs to climb up just to change a song. There are also auxiliary ports and USB outlets for direct connections or charging.
Optional upgrades include higher-wattage speakers, subwoofers, and marine-grade amplifiers for clearer and stronger audio. If you’d rather listen to the radio, there’s a built-in antenna for local stations. All equipment is waterproof, backed by corrosion-proof connections, and mounted out of foot traffic.
Lighting and Night Use
At night, the R4 stays practical and comfortable. Interior LED lighting is placed along walkways, cupholders, and storage areas, making it safe to move around without blinding guests. Navigation lights meet boating requirements for visibility, and a spotlight is available for finding buoys, markers, or dock lines. Optional under-water lights can be installed at the swim platform, providing a unique look and helping night swimmers stay safe and visible.
All electrical switches are made for wet environments, so if splashes happen during a night ride, the systems stay operational. There’s even a courtesy light at the main boarding entry, making it easier to load and unload gear at dusk or dawn.
Customization and Personal Choices
Owners can choose custom color schemes for the hull and upholstery, letting you match your style or stand out on the water. Seat layouts can be selected during ordering, along with options for captain’s chair upgrades, ski pylons, dock lighting, or extra USB chargers. Accessories such as GPS/chartplotters, fish finders, and high-end speakers can be added based on your specific needs.
The flooring can be finished as traditional snap-in carpet or modern SeaDek EVA foam. You can also add wind-blocking cockpit doors, bow fillers, or cockpit convertibles for more sun or shade as desired. These options make it easy to tailor the R4 for fishing trips, water sports, casual cruising, or entertaining.
Tow and Storage Capabilities
At around 4,800 lbs. dry weight (with motor), the R4 is trailerable with many half-ton and full-size vehicles. It fits standard launch ramps and most boat storage facilities. The hull design is reinforced to withstand repeated launching, and the swim platform is designed to avoid hitting most trailer bunks.
The windshield folds flat, helping the boat fit under lower storage roofs or bridges. All cleats are pull-up style, minimizing snags when tying up to a dock or securing on a trailer. With the bimini top removed or folded, the boat has a low overall height for garage or outdoor storage.
Environmental and Eco-Friendly Design
The R4 includes features that help reduce its environmental footprint. The hull is designed to plane more quickly, using less fuel at cruising speeds. Engine choices meet current EPA and CARB emissions standards, and the gelcoat is formulated for durability and easy cleanup using mild soap, reducing the need for harsh chemicals. Waste storage is designed for easy emptying at pump-out stations, helping to keep local waterways clean.
All bilge and sump pumps are automatic, allowing safe discharge without operator attention. Washdown hoses let you clean off sand and dirt before trailering, minimizing spread of invasive species. Standard fuel filters and water separators help protect the engine and keep harmful materials out of the water.
Built for Longevity
With its strong hull, stainless steel hardware, and rot-resistant construction, the R4 is made for years of use. Cobalt’s manufacturing process includes hand-finishing edges, gelcoat, and seams to reduce cracking and leaks. Upholstery has UV blockers and mildew resistance built-in, and is double-stitched at all stress points.
Decks and hatches are reinforced for heavy foot traffic. All latches and pulls are metal, not plastic, and cockpit drains are plumbed for quick draining after rain or splashes. The engine compartment is vented against moisture buildup, helping electronics last longer and start reliably year after year.
Owner Support and Comfort on the Water
When you own an R4, you have a boat that supports adventure and downtime alike. The open cockpit makes it easy to shift from sunbathing to socializing, or to host a lunch for everyone aboard. Removable tables, easy-clean seating, and thoughtful storage encourage all-day trips without stress. Owners frequently comment on how simple it is to switch between activities during outings. From fishing gear to picnic baskets, there is a place for everything, and everyone finds a comfortable seat without feeling squeezed.
For those who are newer to boating, the controls and systems are labeled simply, with instructions available on board and in the manual. This makes docking, trailering, and storing the boat easy. Experienced owners appreciate the solid construction, smooth ride, and continued reliability after seasons of heavy use.
Accessibility for All Passengers
The R4’s swim platform extends well beyond the rear of the boat, with soft, anti-slip surface and a retractable ladder. This design accommodates swimmers of any age, allowing kids, adults, and even pets to board easily. The step-over height from dock or beach is low, providing more entry and exit points.
Handholds are spaced throughout—at the bow, beside each settee, and at the transom—supporting balance and safe movement, even for older passengers or those with reduced mobility. Cup holders, storage, and controls are within easy reach, so everyone can relax and enjoy the day.
Storage Solutions for a Full Day Afloat
Storage on the R4 allows you to bring everything needed for a long day on the water. Deep under-seat lockers hold bulky gear like tubes, while bow compartments keep small items protected. The in-floor ski locker is long and wide, designed to handle multiple boards, paddles, or fishing rods.
Lockable glove boxes provide secure space for wallets, keys, and electronics. In the cockpit, mesh pockets and bins store towels, flip-flops, and sunglasses within arm’s reach. The trash compartment helps keep the deck tidy, and a removable cooler can be loaded at home and stowed in its own bay when you board.
Social Spaces and Entertaining Features
The R4 is made for fun with a group. The bow and main cockpit allow small groups to split up—but stay social. Conversation flows easily in wraparound lounges, and music is available across both seating areas. On the swim platform, there’s space for deck chairs or coolers. With cupholders, tables, and easy access to water, hosting friends for a sunset float or picnic is simple.
LED accent lighting makes evening socializing enjoyable and creates a warm, inviting space. Removable tables stow securely under seats and pop up quickly for meals or games. If it starts to drizzle or the sun gets too strong, the bimini can be put up or taken down in minutes.
Quiet Cruising and Relaxed Days
Some prefer a slow cruise to a hidden cove or a long drift on a quiet river. The R4 is ideal for these moments too. The hull cuts down on vibration and outside noise. When the engine is idling or running at low speeds, passengers can talk at normal volume. With padded seats, comfortable backrests, and easy-to-clean flooring, everyone can relax and take in the scenery. Cushions stay cool and resist fading, even under the summer sun.
Boating with Confidence
First-time owners and experienced boaters alike value the way the R4 handles. The boat takes on wakes and chop with minimal spray, feeling steady as passengers move from seat to seat. Tracking in turns is direct, so even new captains learn quickly. Docking is simplified with wide gunnels, clear sightlines, and fender storage located midship. Onboard safety features, like the automatic bilge pump and overboard alert, add confidence so you can focus on fun and memories, not on mechanical worries.
