She is located in Barcelona Spain.  Ready to Sail Away!

Designed by South African renowned navel Architect, Angelo Lavranos. Built by the Knysna Yacht Company, a boutique yacht builder out of South Africa, they have combined a sleek silhouette with a stylish interior and equipped the vessel with all the liveaboard comforts to take a couple or family anywhere in the world. The key features in the design of the Knysna 500SE allow her to be easily managed short-handed.

The wide transom steps at the stern and dive platform offer easy access for swimming and boarding the tender for trips ashore.  There is a diving compressor (IDE) Bavaria fun 100 and location for up to 4 diving tanks in the Port-board aft locker. Relax on the bows, on the trampoline or in the covered cockpit where the oval teak table seats up to 8 comfortably. The cockpit area is a lovely venue for relaxing and entertaining.

All cabins are bright and light with double beds, air conditioning and fans. The open-plan saloon offers a multimedia system with a flat-screen TV (which can be viewed in the cockpit as well), surround sound and 360-degree views of the surroundings. After the sliding door opens, the saloon and cockpit merge to create one large living, dining, and relaxation area at anchor, mooring or under sail.

ToyBOX is a rare opportunity to own this highly upgraded, turn-key blue-water live-aboard, three cabins, three heads cruising catamaran. Built to premier standards and proven ocean crossing sailing vessel, fully outfitted and ready to cruise. It sails like a dream and is easily handled with sheets and halyards running to the helm. It’s in amazing condition and has been impeccably maintained. The layout of the boat is excellent for a cruising couple and their guests.

This boat systems have been upgraded to allow full control, and off-the-grid, comfortable living. The boat’s primary electrical system is 24V, equipped with reliable CZone™ digital switching thus reducing the electrical cables by up to 40% and enabling full control of the DC and AC systems via dedicated keypads, MFD plotters, dedicated control screen and iPad interface. The 1.0 KW solar array, 4 KW 24V AC/DC chargers from generator or shore-power and 5KW 24V DC alternators charging systems feeding into 15KWH lithium batteries (3) make for simple and efficient energy management. The boat supports and is wired for both 110/230V AC and has multiple multi-standard sockets with USB charging.

The Yanmar common-rail 57 HP engines are located under the beds thus allowing superior weight distribution, higher speed and easy undisturbed maintenance in any sea condition. The Schenker DC water-maker and sizable storage tanks ensure access to clean water when offshore or at anchor. The queen-sized berths, sizable cabins and attached heads with large separate shower areas provide comfortable accommodations for owners and guests.

Vinylester resins have better stretch characteristics than polyesters, so they more closely match the strengths of the various exotic reinforcements. Vinylester also has good water resistance and fatigue properties, but it is more expensive than polyester resin. One important feature of Vinylester is that it has excellent secondary bonding strength, so bulkheads or stringers added to a cured hull will have a better bond than on a polyester hull.

The carpentry was crafted with ultimate attention to detail on the interior, with real maple wood custom cabinetry and warm, bright, homey trim. All rooms and closet doors are made of veneer laminated to structural foam. The carpentry is laminated to the hull for better structural strength and minimal cracks and distortion. 

Multiple windows and hatches create excellent airflow and natural light. From live aboard to hosting a dozen people, the boat has plenty of space and ample storage inside and out. This turn-key ocean-going sailing catamaran will immediately get you on the water to start your sailing adventure, in comfort and style.

She is set up to run the entire boat from the lithium batteries and inverters, including the induction hob,DC Watermaker, Inverter based LG Washing/drying Machine and the water heater. The two Frigomar high-efficiency (inverter heat-pump) air-conditioning (cool/heat) units, The highly efficient variable speed HVAC units automatically ramp up or down depending on need, with approximately 300 watts per unit used at low speed.
