The Silverbirch Covert 9.3 Hydrolite is a lightweight, high-performance solo open canoe designed for fast, technical whitewater river running.

It shares the same hull shape and on-water performance as the Covert 9.3 DuraTough, delivering the speed, control and agility needed for aggressive lines, carved turns and rapid directional changes. Its Hydrolite construction and lightweight outfitting system remove unnecessary carrying weight without changing the responsive character of the canoe.

With a weight of 18.5 kg, the Hydrolite is particularly well suited to paddlers who want an easier canoe to load, unload, carry and move around difficult river access points.

What Is the Covert 9.3 Hydrolite Designed For?

The Covert 9.3 Hydrolite is purpose-built for dynamic river running.

Its compact hull, stepped rocker and balanced volume distribution allow it to respond quickly when navigating technical rapids, changing lines or positioning around river features. It bridges the gap between fast river-running performance and playful manoeuvrability, creating an engaging canoe that remains controlled and predictable.

The Hydrolite version is designed for paddlers who want this performance without the additional carrying weight of the DuraTough construction.

Same Covert 9.3 Performance, Less Carrying Weight

The Hydrolite and DuraTough versions use the same Covert 9.3 hull shape and are designed to perform identically on the water.

Choosing Hydrolite does not make the canoe inherently faster or change its handling characteristics. Instead, its main advantage is the reduced weight when lifting, loading, unloading, carrying or accessing more remote sections of river.

The Covert 9.3 Hydrolite is designed for paddlers who prioritise:

• Easier lifting and transportation
• Reduced strain when carrying the canoe
• Fast and responsive river-running performance
• Precise carving through turns
• Quick changes of direction
• Controlled movement through technical rapids
• A balance of agility and predictability
  
  

Stepped Rocker and Responsive Handling

The Covert 9.3 features 240 mm of rocker at both the bow and stern.

This pronounced rocker helps the canoe turn, pivot and reposition quickly on technical water. Its stepped hull profile is designed to support precise handling and reduce drag, while the balanced distribution of volume creates a stable yet playful ride.

These characteristics make the Covert 9.3 particularly well suited to rivers where the paddler must accelerate, carve and adjust their line without hesitation.

Lightweight Hydrolite Construction

Hydrolite is Silverbirch’s lightweight polyethylene construction for the Covert 9.3.

It is designed to deliver a strong stiffness-to-weight ratio while reducing the overall weight of the canoe. Combined with the dedicated Hydrolite seat and outfitting system, it makes the Covert 9.3 easier to carry and transport without altering the established hull performance.

The Hydrolite weight is 18.5 kg, compared with 23.5 kg for the DuraTough version.

Hydrolite is therefore particularly valuable for:

• Paddlers who regularly load the canoe onto roof bars
• River access involving longer carries
• Steep or difficult put-ins and take-outs
• Paddlers seeking to reduce lifting strain
• Anyone wanting a lighter OC1 without changing the Covert 9.3 hull
  
  

Understanding the Durability Trade-Off

Hydrolite prioritises reduced weight rather than maximum resistance to severe impacts.

It remains a polyethylene whitewater canoe designed for technical river running, but the DuraTough version is the more appropriate choice for paddlers expecting repeated heavy impacts, particularly harsh environments or demanding steep-creeking use.

The decision between the two constructions should therefore be based primarily on your priorities:

Choose Hydrolite when reduced carrying weight and easier transportation matter most.

Choose DuraTough when maximum impact resistance is more important than weight.

Solo Whitewater Outfitting

The Covert 9.3 Hydrolite uses a dedicated lightweight seat and outfitting system designed to reduce weight while maintaining strength, support and paddler control.

Effective OC1 outfitting creates a secure connection between the paddler and the canoe. This helps transfer body movements directly into the hull when edging, carving, bracing or making fast corrections in technical water.

Please check the selected product configuration carefully to confirm the exact saddle, straps, foam and outfitting components included.

Who Is the Covert 9.3 Hydrolite Best For?

The Silverbirch Covert 9.3 Hydrolite is best suited to:

• Experienced solo whitewater canoeists
• OC1 paddlers tackling technical and high-energy rivers
• River runners who prioritise speed and manoeuvrability
• Paddlers who enjoy carving turns and making dynamic moves
• Canoeists who regularly carry their boat to difficult access points
• Paddlers seeking reduced lifting and transport weight
• Those who want Covert 9.3 performance in the lightest available construction
  
  

When Should You Consider Another Model?

Choose the Covert 9.3 DuraTough for Maximum Impact Resistance

The DuraTough version uses the same hull shape but places greater emphasis on durability in severe high-impact environments. It may be the better option for harsh steep creeking, frequent contact with rocks or paddlers who prioritise maximum toughness over carrying weight.

Choose the Covert 10.5 Solo for More Stability and Flotation

The Covert 10.5 Solo provides greater volume, flotation and stability. It may be better suited to larger paddlers, carrying additional equipment or anyone wanting a more forgiving whitewater canoe.

The Covert 9.3 remains the more compact and agile option for paddlers who prioritise rapid manoeuvres and dynamic river-running performance.

Technical Specifications

Canoe type: Solo open canoe / OC1

Intended use: Technical whitewater and river running

Construction: Hydrolite polyethylene

Length: 2820 mm / 9 ft 4 in

Width at gunwales: 570 mm / 22.5 in

Maximum width: 735 mm / 29 in

Bow rocker: 240 mm / 9.5 in

Stern rocker: 240 mm / 9.5 in

Depth at bow and stern: 535 mm / 21 in

Depth at centre: 381 mm / 15 in

Hyrdolite weight: 18.5 kg

Optimum range: 155kg - 285Kg

Ultimate Capacity: 500Kg

The optimum ranges are suggested for typical paddlers in a variety of different water conditions and the users can expect the craft to paddle as designed within these ranges.

The ultimate capacity is derived using an industry standard test of the amount of static weight it takes to achieve a 6” freeboard. This is not a recommendation of suitability of use at these weights.

Lightweight Covert Performance for Technical Rivers

The Silverbirch Covert 9.3 Hydrolite combines the fast, agile handling of the original Covert 9.3 with a substantially lighter construction.

Its compact hull, stepped rocker and balanced volume provide the precision needed to carve turns, change lines and make decisive moves in technical whitewater. Away from the water, the reduced weight makes loading, carrying and reaching difficult access points noticeably easier.

For experienced OC1 paddlers who want responsive Covert performance without carrying unnecessary weight, the Covert 9.3 Hydrolite is the clear choice.
