TESNI
Up to 990 kilowatt-hours of battery and two hundred square metres of solar panel. TESNI is a 2025 Sunreef 80 Power Eco, a 23-metre power catamaran that cruises at six knots on her twin 360-kilowatt electric motors drawing from battery alone, zero emissions, zero vibration, no generator running. Onboard generators serve as range extenders for open-water passages when the solar and battery reserves run low.
She sleeps 10 guests across four en-suite cabins: a king master, two queen doubles, and a twin. The open-plan saloon runs panoramic windows on both sides and opens through full-beam sliding doors onto the aft cockpit, where alfresco dining seats the full party. Up top, the flybridge adds a lounge, sunpads, and a jacuzzi.
A Williams DieselJet 505 tender handles shore transfers and island-hopping. The toy locker carries an E-foil, four Sublue Vapor sea scooters, wakesurf board, wakeboard, foilboards, SUPs, and a standup jet ski, all launched from a hydraulic swim platform that doubles as the garage door. Four crew run the boat, the itinerary, and the programme from season to season.
She works the Balearics in summer and the Caribbean in winter. She is a solar-electric catamaran with the toy list of a conventional 30-metre and the silence of a sailboat.

Good to Know
Key details to help you prepare for your charter experience.
An APA (Advanced Provisioning Allowance) is a pre-paid amount given to the yacht to cover costs like food & drinks on board, fuel, and mooring fees. At the end of your charter, we'll provide you with an itemized breakdown of the expenses, and any unused funds will be refunded to you.
Your Captain will keep you updated if you're close to exceeding your budget. If necessary, they'll discuss how to proceed, which usually involves a simple bank transfer to replenish the allowance.
We recommend around 10-15% of the charter fee as gratuity for the crew. It's thoughtful to prepare a thank-you card or envelope to make the process easier.
We'll provide you with the Captain's contact details well ahead of your charter. We can also create a group chat with you and the Captain to go over any plans and preferences before you board.
We follow MYBA and CYBA contract standards, these internationally recognized agreements offer clarity and security throughout your charter experience.
If you're ever uncertain about what's included or have any questions, feel free to ask your broker at Frontier Yachting. We're here to ensure your charter experience is perfect.
