When the first Oyster 495 hits the water in early 2022, it will sport a Seldén carbon furling mast with new push-button navigation technology developed specifically for this new model, never before seen on a yacht less than 50 feet. .

Relying on its Synchronized Main Furling (SMF) system which synchronizes an electric motor in the mast with its new E40i electric winch for the downhaul during the deployment of the mainsail, Seldén has further automated the system to offer a true push button navigation experience.

To make handling the sail even easier for a small crew, Seldén removed the E40i electric winch from the SMF system and installed small aluminum hydraulic cylinders in the boom to control the downhaul during furling and lifting. deployment of the sail.

Hydraulic boom cylinders for sheet and mainsheet control are not a new concept, but since they were previously large, low pressure steel cylinders, their size makes them larger. made prohibitive for use on yachts under 50 feet.

Seldén’s development of a smaller aluminum cylinder at higher pressure significantly reduced the size and weight of the required power pack by 50%. This innovation means that a hydraulic outlet can now sit next to a hydraulic mainsheet, both of which are enclosed in the boom of the Oyster 495, allowing the owner to push-button control of the sheet. mainsail and sheet.

The system is powered by Seldén’s exclusive control system, SEL-Bus, which is fully integrated across the yacht for all Seldén electrical and hydraulic product lines. The SEL-Bus system converts 12V or 24V to 42V, allowing much smaller and thinner cables around the vessel. The system also communicates between the various on-board units, providing a diagnostic function that allows the system to reduce power consumption by putting the system into “sleep” mode when not in use.

In addition to this creative sail handling solution, which is usually the preserve of many large yachts, Seldén also supplies the Oyster 495 with a Furlex Electric headsail furler, hydraulic downhaul and backstay cylinder. hydraulic – all connected to the SEL-Bus System and controlled at the push of a button from the helm station.

The push-button sail controls on the Oyster 495 will allow the yacht crew to navigate completely from the cockpit, reefing, furling and adjusting the mainsail and headsail in at the push of a button, ”said Steve Norbury, Managing Director of Seldén Mast. “A safe, secure and extremely practical way to navigate, especially with a small crew or with an inexperienced crew.

“We have supplied Oyster with over 50 masts over the past decade on models ranging from 475 to 745, so developing this technology specifically for their 495 not only strengthens our long-term partnership, but demonstrates that Seldén is pioneering design for sail and rig control solutions. ”

Andrew Martin, Oyster 495 Program Manager, comments: “Oyster is delighted with the bespoke development of the SEL-Bus furling system which, together with a one-button solution for mainsail management, carries the automation of sailing to another level aboard the Oyster 495. just another innovation that will make the navigation of this new generation of ocean-going sailboat a simple pleasure for a couple or a young family.

“The mast wrap has long been Oyster’s proven and reliable sail plan. The SEL-Bus compact reel hydraulic power system is simpler to install on our small boats and, along with other unique features, sets a very high standard on this new blue water benchmark. ”
