WallyCento Open Season
C-Designs delivered a unique systems package to the 2012 award winning WallyCento Hamilton, the first of its class, overcoming some exceptionally demanding challenges along the way.
The superyacht, commissioned by Sir Charles Dunstone, was constructed in keeping with the Wally ethos, to promote high performance yachts with comfortable cruising interiors and simple sail handling systems. Sir Charles had previously found himself in uneven contests against boats with disparate ratings in his Briand designed 35.65metre Hamilton II, which was put under loads not anticipated during her design for cruising in 2005. Wally founder Luca Bassani became aware that Dunstone’s position was not unique and, following a consultation process culminating at the Wally AGM in 2010, the WallyCento class was created.
The team assembled to produce Hamilton consisted of top names within the industry: Judel/Vrolijk was employed for the naval architecture; C-Designs for the design and installation of the systems; Design Unlimited for the interior and exterior design; Struik & Hamerslag to fit the interior; Diverse Yachts to provide the electronic systems and Green Marine to provide the composite work at its Hythe premise. The project was managed by a team including the owner’s representative James Stagg and Design Coordinator Richard Clampett, along with Richy O’Farrell who would go on to skipper the Superyacht. Hamilton was launched as planned in July 2012 and won the Superyacht Cup Regatta in Cowes after just five days of sailing.
In all aspects of the construction, Hamilton presented a particular challenge in the demanding weight and displacement parameters determined by her design and as a result, C-Designs presented a comprehensive suite of custom systems that enabled the superyacht to meet certain class rules whilst keeping the weight considerations the highest priority.
Nick McGarry, Managing Director, commented, “This was a very demanding project undertaken on a tight time schedule and I am very proud of the contribution the C-Designs team has made towards fulfilling the brief. Our long experience in optimising the systems for sailing superyachts undertaking both racing and cruising enabled us to devise solutions for Hamilton that are both innovative and practical.”
Devoting over 9000 hours to Hamilton, C-Designs utilised every practical opportunity to save weight, down to the smallest detail of carbon pipe racking and cable support systems. The keel ram cylinders, for instance, were made using high strength alloy wrapped in carbon fibre, and titanium was used widely throughout.
C-Designs were also tasked with designing the entire systems package in 3D which would allow accurate comparisons to be made between the preliminary design and theoretical build weights. “From early on in the build process we were able to predict with considerable accuracy the final systems weight which had huge reliance on the final weight of the bulb” added Ben Pym from C-Designs, who furthermore was able to provide the naval architects with co-ordinates for the centre of gravity for the systems package in its entirety.
The hydraulic system demanded particular attention in order to manage the enormous loads generated by the rig and by the requests of the crew for efficient sail handling when racing. C-Designs rose to the challenge, creating a powerful hydraulic system that was able to generate the necessary power and distribute it around the boat, whilst also keeping the total weight to a minimum.
It was also required that certain controls be accessed remotely and C-Designs presented a unique PLC (programmable logic controller) to satisfy the request. Through touchscreen displays, the hydraulics can be controlled in terms of cruise or race mode, for example, which automatically adjusts the settings to allow for safe shorthanded cruising or flat-out racing. The system also permits domestic controls such as air conditioning and lighting to be accessed remotely through an iPad interface, allowing complete control from anywhere on board.
Since Hamiltons launch, C-Designs have continued to develop the sailing systems through collaboration with the race crew and have installed a number of additional features with the aim to increase performance on the racetrack.
Hamilton won the Sailing Yacht 30-39m category at the World Superyacht Awards 2013, where technical excellence and exceptional performance was praised along with the ingenious and imaginative engineering and extraordinary attention to detail delivered by all involved.
E-Plex - Digital Control & Monitoring
C-Designs often encounter builds where weight must be kept to an absolute minimum in order to optimise performance. However, conventional AC and DC switchboards present a problem being heavy installations due to the large volume of cables. In collaboration with industry leaders and using a combination of E-logic software, touchscreens and an innovative EP3-bus system, C-Designs have progressed from old conventional switching to a new style of digital control and monitoring (C&M), creating an intuitive, lightweight system that can be accessed via ipad , tablets and PCs with stunning graphical HMI.
With conventional switchboards which are limited in terms of customisation and consist of individual wires for switching and that lead to each consumer on-board, the result is excessive amounts of cabling adding weight and taking up valuable space.
C-Designs developed a way through which all necessary systems, from battery voltages to bilge pump controls, could be monitored efficiently and remotely. Fuel and water tanks, as well as air conditioning and lighting, could also all be controlled through the same portal.
This was achieved through the bus system, which communicates to localised modules around the boat . These modules have multiple functions and are linked to the vessel’s WI-FI via a single network cable. The information is then displayed through various wireless & fixed portals, such as iPads and PC.
This control & monitoring system benefits from being entirely customisable; the monitor can display a homescreen linked to various alarms of the clients choosing, such as bilge pump activity, battery voltages and high/low tank levels. In addition, the monitoring system can be accessed remotely via integration with an SMS unit to send a message if, for example, the shore power is unplugged, or if the bilge alarm reaches a high level. It also includes further options to turn on functions such as heaters, fridges and lights before arrival on-board.
On the WallyCento Hamilton, there are two monitors on-board; one at the main control station in the galley and one on deck, which displays the C&M interface, monitoring critical information required by the skipper enabling him to stay above deck when racing and access information with simplicity and ease. Hamilton also operates the software on an iPad, which mirrors the vessels monitors allowing complete control from anywhere on-board.
The system was first utilised by C-Designs on the Marten 68 Cassiopeia (2012), and has since been fitted on the WallyCento Hamilton (2012) and the Hoek 47 Elsa (2013) with much success.
Canard Skate Bearing
C Designs were tasked to come up with an improved bearing design for asymmetric dagger-boards, the brief was to find a lightweight solution that would give a large bearing surface to minimise point loading on the foil, leading to a lighter foil structure and reduce friction allowing deployment at higher speeds and reducing the loads required to move the foil.
Our design was inspired by heavy load moving skates commonly used in industry to move machines across factory floors. Taking this concept, incorporation of a spherical rear bearing seating to allow for the foil bending and shaping the bearing race to let the rollers follow the foil profile.
The bearing design has been developed over the past five years and now used successfully in Open 60 Artemis, Volvo 70 (Puma) and 100 ft Maxi (Wild Oats XI) a variation on the design was also used on the AC72 Oracle.
Titanium Anchor Arm
With a proven track record in high quality custom-made mechanical assemblies C-Designs were approached early in 2015 to undertake a design study, with intent to manufacture, on a stowable anchor arm for a series built superyacht for a luxury yacht brand.
The arm as pictured, is capable of being stowed below deck whilst sailing or not in use and controlled by a local remote utilising the hydraulic system on-board is deployed through 180°, midway through which the inner telescopic arm via the use of an integrated hydraulic ram travels 600mm in order to avoid the enormous 160kG plough anchor on the end of the arm clashing with the yachts bowsprit.
The use of Titanium in such an application proved a fantastic challenge for the design team who needed to consider new design and manufacturing methods tailored to the materials unique properties.
It was with theses challenges in mind the team embarked on a programme of testing to ensure that the entire process was understood to guarantee a successful weld of the final 10mm thick cut plates profiled via waterjet.
The final arm is due for launching with the yacht in 2016 and is 44% lighter than it’s near identical stainless steel counterpart.
Delivered was a full actuation assembly to include two titanium hydraulic rams, the two inner and outer sections of the anchor arm, which was fully assembled in house to allow a simple ‘drop in’ assembly at the yard.
