Vacuum resin infusion is the process at the heart of our technology and is used for all parts.
The vacuum resin process removes all of the air between the fibres of a part prior to the introduction of the resin.
After the process, our parts are meticulously sanded with variable grit — allowing for maximum paint adhesion on surfaces and smooth, stylish edges.
Core materials are introduced into the part to increase stiffness without increasing weight.
The core is a structural-grade foam with a high shear strength characteristic: if the part is of a complex shape, we cut the foam into sections, thermoforming it to the required shape.
We use five different sizes and densities of foam on the boat, optimized for local strength requirements.
We purchase carbon fiber by the roll and over 35 rolls are used in each boat. We have engineered the laminate schedule to be most efficient in the various areas of the boat maximising strength and reducing weight.
Each meant to be the most efficient for their respective areas. The fabrics are stitched, instead of weaved.
Stitched fabrics do not need to bend over or under other fibre and lay flat, making a stronger part.
At Open Waters, it is our mission to make catamaran cruising more exciting and environmentally sustainable. We’ve set out to create a performance cruising catamaran that will be a joy to sail and that will raise the bar in environmental sustainability.
We have developed a unique design and manufacturing process, selected high performance materials that enable us to build a boat that uses less materials and is 50% lighter. As a result it is a lot faster and as a result it is able to generate and store the energy needed to propel it electrically for hours and provide enough energy for on board equipment.
We use high performance carbon fibre and a vacuum infusion process to maximize strength and reduce the use of resin and eliminate resin vapour emissions. We use 100% recycled PET foam core wherever possible and we see the opportunity for incremental use of bio-based epoxy and natural fibres in our future.
As we continue to develop our sustainability roadmap for our boats we will perform a full lifecycle analysis to identify other opportunities to minimize our carbon footprint.
The unique processes and skills we have developed can be applied and licensed to other marine and recreational vehicles businesses.
Simon Angus P.Eng is a professional mechanical engineer with a background in project management and a passion for sailing.
He spent his university summers travelling around Europe searching for the best combination of wind and waves in addition to teaching both sailing and windsurfing.
After moving to Canada in 2004, Simon bought a Catalina 27 in Kitimat BC and enjoyed sailing in the Douglas channel with his young family. A career move to Alberta paused his sailing career until he found the joys of chartering sailboats in the Caribbean.
After a 20 year career in industrial engineering and project management he decided to make a change and combined his passion and profession to launch Open Waters Design and Manufacturing in 2016.
He designed and manufactured an 18ft canoe and developed a plug and mold and his proprietary vacuum resin infusion process. After the successful build of the canoe, Simon built a high performance 18ft A class foiling sailing catamaran out of a Carbon fibre and refined the mold construction and vacuum resin infusion process.
After researching the various build steps, Simon started with CNC shaping of a plug, hand finishing and building the hull molds. He also built the mast, Z foils and the Tee foil rudders. After successful trials in Vancouver BC, Simon then set out on his next ambitious project, to design and build the boat he had dreamt about for years.
A boat that could be shipped anywhere in the world, sail on with his family and returned to Vancouver for summer cruising and would be electrically sustainable.
Simon was introduced to Hal Whitacre in 2019 which started a design relationship that has resulted in the creation of the Open Waters ESC40.
Hal Whitacre, owner of Whitacre yacht design since 1984 and is responsible for some of the fastest and most luxurious boats ever built.
Hal is Open Waters Chief Naval Architect and has worked closely with Simon over the past 2 years to produce the detailed designs that make up the Open Waters ESC 40.
Hal has a distinguished career in Naval Architecture graduating from the University of Michigan with a degree in Naval architecture and Marine Engineering.
Throughout his career he has pushed the boundaries of naval architecture notably designing the Open Class 60 “Imagine”; breaking ground with the largest rig ever put on an Open 60.
Hal also owns and operates Bruce Roberts USA and in that capacity, he has designed over 100 steel and aluminium boat kits in addition to many fiberglass and wood sail and power boats. Most recently, Hal was the chief Naval Architect for Gunboat Catamarans when they were built in the USA.
Since their move to Europe, Hal has completed 2 gunboat 55’s along with a conversation of a gunboat 55 to a powercat ferry which has recently conducted successful sea trials.
Hal and his wife Tammy split their time between Annapolis, Md and Sister Bay, Wi. Hal continues to race Lasers during the winter and windsurfs/foilsurfs as much as possible.
We’re hiring!

Whitacre 47 Performance Offshore Catamaran
The WHITACRE 47 is designed by Hal Whitacre Yacht Design in collaboration with Big House Yachts and James Betts Enterprises. Our vision believed there was a need for a simpler and more affordable limited production, semi-custom performance cruising catamaran.
While the leading/bleeding edge of technology looks very cool on paper or dockside, it can become an issue once it’s out in service. The increasing tech found in today’s higher performance multihulls often supports the need for full-time crew. Our vision brings together performance composites, system and rig simplicities, hybrid energy technologies, and affordability in a limited production, fully customizable offshore catamaran. Partnering with world-class performance sailboat builder Betts Boats, we’re delivering a epoxy e-glass/carbon composite catamaran with proven and reliable build quality that complements the proven Hal Whitacre engineering and design experience.
Whitacre 47 Hull #1 is in production with expected completion Spring 2024. Build production slots are available for immediate start with finish projected Spring 2024.
The Whitacre 47 offers the benefit of limited production customization with pricing from $1,160,000 basic sail away to $1,500,000+ for custom upgraded interior layout, equipment, and finishes.
Made in USA - Anacortes, Washington

Can someone give me a little bit more info on c-flex .Is there another name for it or is it carbon fibre?Ive never actually seen it or carbon fibre before so Im a little confused.I did some research and found that its got fibreglass rods in it.is carbon fibre a different material altogether.?Im actually looking for a European supplier .Any help on this would be greatly appreciated.thanx in advance.
C-flex is not carbon fiber - they are different materials all together. From: http://www.bruceroberts.com.au/building/methods/c-flex.htm This combination of rigid rods held together loosely, with pliable areas in between , is what makes C-Flex unique in construction materials. In our knowledge, it is the only self-supporting material available today which will conform to compound curves without having to be stretched or deformed in some way. Furthermore, C-Flex will bend sideways, a property which virtually eliminates the problem of having to fit or spile the ‘planks’. Most boats can be built by starting the first ‘plank’ parallel to the sheer line then butting the next ‘plank’ right alongside all the way to the keel. Aside from the obvious advantage of being able to build an all fibreglass boat without a mold, C-Flex also affords the designer and builder the opportunity to save weight over a conventional fibreglass laminate without sacrificing strength. This is because C-Flex is an unidirectionally reinforced material and is considerably stronger in the direction of it’s fibre orientation (lengthwise) than an ordinary fibreglass mat or woven roving laminate.This property is used to save weight in the hull shell by running the C- Flex along the lines of anticipated greatest stress (usually fore and aft). The weight savings also translate into a cost savings. Even though the C-Flex itself costs more per pound than mat or woven roving, the completed hull shell will cost about the same as a hull built with just mat and woven roving. The advantages of being able to build without a mold and the weight savings are a bonus. Click to expand...
The cost savings are offset by the amount of labor involved in fairing. If you are building your own, one off boat, it is great. For production is too labor intensive.
Siemens fiber glass who used to make c flex used to have a video on hull construction using it- I dont know if they still do or not.
Building on a jig, one off, you will want to make sure your use plenty of jigs, close together. If you don't you will run into a big problems with fairing huge amounts of low spots, in the hull. Also if I recall, since it has been around 15 years since i reesearched it, but the initial resin is different for the initial layup of the strands for building a hull made up entirely out of it. It was also used in coating older wooden hulls for a "few more years" of life. It is bedded in 5200 to hold it to the hulls, initially.
C-Flex is like a long plank. The fiberglass rods fair nicely. Tie them to the jig with copper wire.

Naval Architect Cflex is an interesting building method as it allows a builder to build an essentially single skin fiberglass hull without a female mold. I have not heard of applying Cflex over an existing wood hull but then I havent heard all..! From what I understand of the building method fiberglass rids are laid over a male mold (with short frame spacing..) and then coated/filled with a thick polyester casting resin. When that has all set, fibreglass fabric set in polyester resing is applied over the structure. Finally the surface is faired, painted etc. There are other methods to obtain a single skin hull, but all require some sort of female mold. Cflex is a viable alternative to building using female mold techniques. Hal Whitacre Naval Architect Whitacre Yacht Design Annapolis, MD USA
I am considering purchasing the 1974 Spencer 1330 (44') plug designed by John Brandlymayer and built in Richmond, BC by Spencer yachts. Cflex was used as the core material for the plug construction. During the survey it was noted that "a number of fluid-filled blisters to be present on the underwater body. Some of these were between what appeared to be an epoxy barrier on the outside of the hull, some where between what appeared to be two layers of fairing compound and some were between the inner layer of fairing compound and the skin out coat so that the fibreglass within were exposed and fluid-soaked." The surveyor did not think much "plugs" in general and suggested specifically that the bottom would be required to be "peeled and reglassed." I don't believe the blisters are structural in nature as 6 areas about 6" x 8" were identified. I believe they could be repaired locally. I am interested in hearing from anyone who has knowlege of repairing blistered hulls with Cflex and what the characteristics of Cflex is when it gets water saturated. In addition, I am concerned regarding the actual plug construction lay-up schedule and resulting displacement. I understand that accelerated rig fatigue and the stability curve can be negatively impacted if the vessel is not to the original design specifications. I am considering retaining a marine engineer knowledgeable about the Spencer 1330 design to review and answer some of my concerns regarding the plug construction. I would appreciate any comments or suggestions from anyone with Cflex blister repair experience or regarding "plugs" in general. Thank You
