Brute Force Innegra Canoe

The toughest, impact resistant composite canoe


Brute Force appearance options are – Natural Innegra Basalt exterior & Interior

H2O Brute Force Canoes fill a void created by the vacant ABS formed White Water Canoes no longer in production. Brute Force has currently the most comparable impact resistance and inherent toughness available in a resin matrix composite Canoe.

Brute Force is constructed utilizing Innegra Fabric on its skins, sandwiching multiple re-enforcement layers of Fiberglass and Kevlar with a closed cell foam core for longitudinal rigidity.

Advanced techniques and selections keep the overall weight of the finished Canoes remarkably close to the 50lb Tripping Canoe targets which is some 25 – 40lbs lighter than traditional ABS sandwich formed Canoes.

Brute Force is not only one “Tuff Bugger” but an attractive Touring Canoe in its natural Fabric finish.

Brute Force by Design

The H2O Canoe Company Brute Force Canoe is constructed uniquely from other H2O laminations. It has a closed cell foam core bottom with substantial re-enforcement through the bilge and freeboard. Finishes including the full Aircraft grade Anodized Aluminum Gunwale versus the ICG are selected for ease of use, maintenance free longevity and resistance to damage – Brute Force Canoes combine advanced material selection with many innovate concepts and fittings. Each part has their own purpose within the system to fill a role in creating the ultimate package of performance, lightweight and durability.

The Brute Force lamination design goal is to achieve a high quality Canoe just over the 50lb finished weight range for a Canoe around 16’6” long. 17’ and longer Canoes will be heavier but still very manageable for their overall size.

Similar build concepts to other H2O Canoes combine techniques that all result in an important end goal. Which is – The most amount of weight and thus material (re-enforcement) is in the hull of the Canoe itself. The more substance in general and quality substance in this case the hull is made out of, the more resistant to damage it can be.

The greatest difference with Brute Force is we are accepting the final weight may be more than other construction laminations by design; to add as much thickness and structure in flexible impact absorbing areas of the Canoes exterior as possible, so it may participate in activity previously deemed inaccessible by composite Canoes.

Principles following apply to the Brute Force.

Too many Canoes on the market simply take away substance from the hull to make it lighter but carry on finishing the Canoe in a “standard fashion”, selecting heavy wood species, heavy Gunwales, wetting out flotation chambers with thick layers of FG and resin and covering the interior of the Canoe with a heavy, thick layer of Gel-coat. None of which these effects add value or reduce weight to an ultralights resistance to damage or enjoyment to carry.

It only stands to reason if a majority of the weight in your toughened Canoe is made up of finishing’s and trim your hull can’t have much substance to it. This is why so many beautifully Gel-coated Canoes touting to be “Tuff” are quickly a mess of cracks and damage. They are simply a significantly heavy Gel layer backed by very little re-enforcement and an average quality resin. There is too much overall weight invested in Gel, trim and components that while nice to be heavy duty leave no weight to invest in the actual lamination of the hull.

Specific identifiers of the Brute Force Canoe

The significant difference in our Brute Force Canoe from other H2O Canoes & any other Canoes in the market touting “Tuff-ness” is the sheer thickness of the hull itself. If opportunity presents, feel the hull of a Brute Force lamination, your senses are accurate. Brute Force Canoes feel “thick”.

Brute Force laminations always will be in natural Innegra Basalt fabric which the combo of Black and White fabric appears Silver.

Key Feature Brute Force Canoes – #1 No Gel-coat & Core Shell Resin

H2O Brute Force Canoes are constructed using no Gel-coat on the exterior surface area. This is a large weight savings in coating that can be re-applied to the laminate with re-enforcement. The exterior layer of Innegra Basalt is protected by a light UV resistant layer of a clear product weighing 80% less than a typical Gel-coat layer. Innegra Basalt is inherent tough and highly repairable which would make the heavy layer of coating redundant to be the scratch coat.

H2O uses a ”binder” to allow us to use our tough Core Shell Vinyl ester resin on Brute Force even though we don’t have a typical layer of Gel-coat for V/E production. The Core Shell resin is similar in application to Epoxy resin for impact resistance but allows us to keep Brute Force at a lower price point more attractive to White Water Trippers and Paddlers inevitably running into some things along the way. To use Epoxy would push the price point too high for a Canoe much heavier than typical ultralights at higher price points.

Core Shell resin is the right resin at the right time for Brute Force by H2O.

Core Shell tests similar in many ways to Epoxy resin for physical stresses of impact, flex and is inherently UV resistant. H2O test results show Epoxy resin to be superior overall but the nature of the Core Shell for cost savings and appropriate processing in the Brute Force matrix is an excellent choice.

Key Feature to Brute Force Canoes – #2 extra thick re-enforcement

Brute Force Canoes do not have the bilge ribs other H2O Canoes have. The bilge re-enforcement is so substantial in Brute Force we forego the rib system for the concept of impact absorption by flex.

There is enough re-enforcement in strategic places that even without foam ribs the Canoe is structurally rigid for paddling. The advantage upon impact this way is the Canoe has just enough “give” to absorb a heavy impact, but effectively flex through the impact, reducing damage to an otherwise immovable re-enforcement. There is a rebound effect promoted by the bilge be somewhat flexible throughout.

What is significant about the thickness of re-enforcement in Brute Force Canoes?

Fabric for composite construction is often described in ounces/square yard. A typical Touring Canoe will often be made up of 3-4 layers of 5-8oz material. This maxes out your material ounces at around 32oz. Generally accepted as substantial by anyone making high end re-enforced Canoes.

H2O Brute Force is 2 layers of Innegra Basalt which are 9 oz each, that’s 18oz already. Sandwiched in between is 26oz of fiberglass which puts us up to 44oz. Add to that multiple spot re-enforcing of 5oz Kevlar, 9oz Innegra/Basalt and even more 26oz FG in stress areas. Areas of a Brute Force are in the neighborhood of 80oz of material – close to triple that of an average “Tuff” Canoe.

Key Feature to Brute Force Canoes – #3 Lightweight finishes and trim

As we discussed our goal is to place the most amount of substance (weight) in the hull itself. We accomplish this by selecting lightest weight species of Wood for Components; design a Gunwale system which is significantly lighter than many other Aluminum or Wood concepts and apply techniques to add features typically heavier, which add no value being heavier.

Components of a Brute Force Canoe

Core Shell V/E - Vinyl ester resin is a “snap” cure product which is advantageous in processing for time and curing efficiencies. A catalyst mixed with the V/E resin promotes a reaction which then heats and cures the resin into a solid. When it is cooled it is fully cured and needs no further processing to achieve top physical properties.

The single most important element in a Canoe is the resin holding it together.


The choices manufacturers make on where to save money impact greatly on the quality of product consumers receive.

Brute Force Canoes are a little less costly than EPS Canoes and Helium Canoes because processing and material costs are a little less for re-enforcements and its finishes. The reason they are only a little less is that even though the materials have moved down a selection, the scale has only moved from ideal to excellent.

Like most choices in any materials there is a vast quality range. H2O Canoe Company Canoes from top to bottom make choices in the highest of that range regardless of what category of use they are targeted. Every aspect of the Brute Force is made from the best selection available for quality and durability in its material selection range.

H2O Core Shell V/E is currently the best available V/E resin for marine composites. It shows results comparable to Epoxy for impact tolerance, flex and bond. V/E cannot be used directly against a bare mold like Epoxy so it is processed with a binder tying together a light clear coating with the resin.

Gel-coat is a layer of substance which is brilliant and UV stable. It is highly attractive and impressive so some paddlers would not go without. H2O uses a Gel-coat with a flex agent making it more pliable to resist damage.

Both the Core Shell resin and Gel-coat is repairable and will marry to polyester and Epoxy repair resins.

Advanced Fabrics

– Re-enforcement in fabric form layered and positioned strategically for strength and rigidity of the hull.

Fiberglass – common boat cloth, excellent resin retention, easily repairable, structural when saturated with resin.

Innegra – polypropylene based material with excellent flex, impact absorption, ideally combined with another fabric in a blend to share bond and resilience characteristics.

Basalt – Earth mineral resource sharing characteristics similar to Fiberglass and Carbon Fiber. Wets out well with resin.

Kevlar (Aramid) – Aramid is the product, Kevlar is a brand within the product category, Twaron is another product within the Aramid family. Aramid is resistant to tear, impact absorbing and structural when wet out.

Carbon Fiber – Carbon Fiber is the most advanced material available for light weight composite construction. Elegant aesthetically - replaces multiple layers of Fiber-glass for structural rigidity.



Foam Core – the base of the hull is closed cell high density foam. Providing rigidity against Boat twist and oil canning, this component is essential to a well performing Canoe.

Skeletal Rib – The H2O Canoe skeletal rib system is part of a complete re-enforcement system. The ribs fill the role of supporting and tying in the foam core to the sheer line of the Canoe for bilge stiffness, eliminating torsional flex and are much lighter yet stronger than additional bilge layers of cloth


ICG – Integral Composite Gunwale is the combination of foam cored gunwale wrapped in Kevlar, Carbon or combinations inherent to the hull itself - with an outer aluminum trim for impact resistance and rack sliding. The ICG is the top plate in a joist type construction system of ribs and foam core. ICG construction weighs approximately half a regular aluminum Gunwale set.



Resin Infusion – this is an advanced process method of wetting a dry stack laminate under vacuum pressure. Only as much resin as is necessary to adequately wet out the laminate is used under pressure- surrounding core, filling voids and saturating the re-enforcement. Resin infusion ensures consistent weights, void free laminates and is environmentally friendly, as resins cure under closed molds with no off-gassing.


Preformed Flotation Chamber – Flotation chambers constructed on a form in a similar process to the Canoe hull by vacuum processing. “Float tanks” made this way are bonded onto the hull with an adhesive and sealed using much less product compared to wetting out a form with Fiberglass and resin to create flotation chambers.

Bilge mounted seat brackets – Attaching the seat on a bracket attached and bonded to the bilge of the Canoe creates a stiffening opportunity across the Canoe adding to its overall rigidity. This is further to the “system” doing everything possible to make each component in the Canoe fill a role in creating structure. Also seats mounted this way will not sway or wear on the gunwales.

Light weight component selection – Naturally rot resistant, yet ultra light wood species for the interior components ensure longevity and weight savings. Natural tone or Blackout available.
