"The 523 made a big impression on Cruising World Boat of the Year judges, who named it Best Full-Size Cruiser for 2006... When the Boat of the Year judges were summing up their impressions of the 523, they agreed that it “hit the cruiser’s sweet spot” in many ways, from the generous living accommodations to the cockpit to the sails to how it handled under sail and under power." ~ Cruising World

Beneteau Oceanis Clipper 523
"The combination of Bénéteau expertise in highly respected cruising yachts with that of Groupe Finot in 60-foot Open racers has given birth to the Océanis Clipper 523. It has been designed for demanding owners and for voyages where pleasure, luxury, comfort and safety are the only masters on board. The deck equipment has been designed for optimal manoeuvrability and accessibility. Cabins with private heads, a saloon laid out with sophistication, exceptional lightness, carefully chosen materials - nothing has been left to chance where the interior accommodation is concerned - making every day on board an exceptional experience." Group Beneteau Brochure
Modification to Sunflower
Sunflower has been extensively updated over 18 years first to support long range, extended cruising; then to be a fast cruiser for ocean racing. This list includes the updates and modifications.
The hull below the waterline has been custom faired and sprayed with an exceptionally hard ablative bottom paint for speed yet also suitable for cruising without the need to scrub the bottom.
- Includes complete spare rudder & hardware. This is the only existing spare Oceanis 523 rudder in North America (verified by Beneteau).
Standing and Running Rigging
Nothing is left of the original Beneteau rig. The spars, standing and running rigging, and all blocks/winches/hardware are top quality and sized for ocean sailing.
- Mast and boom are custom built by Forespar and installed in Spring 2011 by New England Yacht Rigging, Inc. The standing rigging is discontinuous and strongly built with robust spreader tip, end fitting and turnbuckle hardware. You can see the heavy-duty welded plates of the Passage Maker tangs for the standing rigging. Note the sturdy Leisure Furl gooseneck. The hardware and materials are representative of the quality and strength of these major improvements to the boat.
- The aluminum mast is anodized, as well as, painted with Awlgrip paint. Several cosmetic repairs to the paint have been made as it has worn in the course of cruising and ocean racing. The Leisure Furl Boom is anodized aluminum.
- All standing rigging replaced from the original Beneteau equipment in 2011 with the exception of the (V1) deck to spreader lower portion of the upper shrouds which were replace in 2019.
- The halyards are constructed of high tech line and built to withstand offshore conditions. Note additional dyneema chafe sleeves on the shackle ends. The shackles are over engineered for the typical loads. All the halyards have been replaced in 2018 and 2019.
- Examine the genoa, spinnaker and both the inside shroud & outside shroud staysail sheets that are hanging in the forward lazarette compartment. You will see that they are all high tech lines custom spliced with either strong soft shackles or oversized trigger shackles. They all are just a couple years old and have only been used racing to Bermuda 3 times. There is also a complete set of cruising sheets.
- The original furling systems have been replaced. The headstay furler is a Schaefer 4100 and the Staysail furler is a Schaefer 2100.
- The cars for the headsails have been replaced with ball bearing towable cars. Two small winches were added to adjust the cars.
- Note the quality of the Schaefer roller bearing blocks on the mainsheet system. Other high load blocks are also torlon roller bearing high strength blocks.
- Numerous additional items of running rigging have been modified or added. The spinnaker tackline that doubles as a whisker pole downhaul is new as are the twings and Genoa furling line and blocking. Two Lewmar 62 manual two speed winches and custom fittings have been added to handle sails better and to run two headsails simultaneously. These winches also handle the jibe preventers and spinnaker sheets. These upgrades make the boat not only pretty but fast.
- The headsail sheet lead systems on the side decks have been re-engineered, upgraded to towable cars for precise trimming and a winch has been added next to each steering station to adjust the cars. Custom pad eyes have been welded to the arch to rig the storm trysail and to attach the spinnaker turning blocks. Tour the decks and you will see many custom layouts that make management of the sails from the cockpit easy and convenient.
- A carbon fiber Forespar whisker pole and mast storage hardware have been added to make pole handling a breeze.
- The original mainsheet traveler has been completely replaced with a Harken heavy duty traveler system. The Traveler car can now be handled by one person from one side of he cockpit under the dodger.
- Spinlock rope clutches have been added and rearranged. The cams have been swapped out as needed to best fit the line size. The lines all run straight forward and do not cross or chafe.
- The genoa, stay sail, and mainsail can be handled by one person in the cockpit. A person only has to go out of the cockpit to set the spinnaker, the whisker pole, or the storm sails.
- The boom is rigged with a jibe preventer on each side. When rigged, we have a line run from the outboard winches to a block forward and back to connect to the jibe preventers on the boom. The jibe preventer can be set while the boom is fully out to either side.
- The mast and boom running rigging has a good deal of redundancy. There are two spinnaker halyards that can also serve as halyards for other sails as need. They are also used to hoist the genoa and staysail socks when racing sails are furled. The boom topping lift is engineered to serve as a mainsail halyard should need be. The boom is supported by a rigid vang when the mainsail is furled.
- Winches are cleaned and lubricated annually at least.
All sails are made by Thurston Quantum Sails in Bristol, RI. All sails are maintained annually by the sail loft.
