Excess 11 - The Perfect Escape, Ready to Go

Launched 2024 | Extensively Upgraded | Turnkey Liveaboard | AU$1,400,000 + Replacement | Asking price: $980,000

Every so often, a boat comes along that isn't just fitted out -- it's thoughtfully transformed.

This 2024 Excess 11 was born from a dream: to explore the East Coast of Australia, cross the South Pacific, and beyond. Over twelve dedicated months, she was upgraded, refined, and perfected into a fast, comfortable liveaboard -- the kind you can take anywhere.

Plans changed with an unexpected addition to the family, and now this meticulously prepared catamaran is looking for her next skipper -- someone ready to take her on the adventures she was built for.

Purpose-Built for Performance and Ease

From the sail plan to the helm, everything was designed for confidence and simplicity.

o Carbon sails, self-tacking jib, spinnaker gear, and electric winch make her an absolute joy to sail -- even single-handed.
o Coppercoat antifoul means you won't need to haul out again for 10-15 years.
o Performance and reliability meet low-maintenance practicality -- so you can focus on the journey, not the upkeep.
____________________________________ ____

Freedom Through Power

Stay off-grid for weeks without compromise.

o A fully integrated Victron power system -- 8kW Lithium batteries, inverter, 1300W of solar, DC-DC chargers, and isolation transformer.
o Fully remote-monitored and self-managed.
o Enough power to run all the comforts: hot water, microwave, coffee machine, toaster, full-size washing machine -- even the hairdryer.

This isn't a typical "cruising setup. " It's a true floating home engineered for independence.

Smart Navigation and Safety

No expense spared on the electronics suite.

o Full B&G network with multiple displays, chart plotters, ForwardScan sonar, Halo radar, and wind/depth/speed/temp sensors -- all controllable via Bluetooth remote.
o Icom AIS & VHF, each on dedicated circuits, integrated via NMEA2000 with Shakespeare Phase III antennafor crystal-clear comms.
o Designed for safety, redundancy, and control in all conditions.
____________________________________ ____

Designed for Comfort, Inside and Out

This boat doesn't just sail well -- she feels right.

o A proper mattress in the owner's cabin.
o Block-out blinds, mosquito nets, and Sunbrella cushions throughout.
o Fans in every room and USB ports wherever you'd want to charge.
o 5G modem hub for reliable onboard internet.
o Evenings glow with multicolour LED lighting, underwater lights, and powerful deck flood light.

You'll feel it the moment you step aboard -- every detail chosen by an around the world sailor, a dream boat, not a spec sheet.

The Perfect Tender Setup

Your adventures don't stop when you drop anchor.

o 3.1m Lomac RIB with centre console, powered by a white 20hp Suzuki (planes comfortably with 3 adults).
o Stainless steel davits with electric winch lift and secure it with ease.

Ready for Her Next Story

Everything has been done -- professionally, properly, and recently. She has been refined, tested, and tuned.
What you get is a ready-to-go, adventure-proven catamaran that would cost over $1.4 million to recreate -- without the waiting, the setup time, or the trial and error.

If you've been waiting for the right boat -- one that feels like home from day one -- this is the one.
