Mumby 48
An Australian registered boat that was professional built to the highest standards so it could be sailed safely around the world in comfort at high speeds. She's number 36 of these ocean going boats.
The interior is beautifully fitted out in seamless moulded fiberglass, it is easy to clean and is maintenance free.
The floors are hand layed rosewood and beach wood, the cupboard doors are hand crafted from red cedar.
It has kick up rudders with shaft driven propellors, that allow it to float in 0.6 meters of water.
All deck gear is over sized to safely handle performance loads and speed on long ocean voyages single handed.
Boat is set up to run on solar and wind, so no need to run the motors while sailing.
Owner baught the boat from Tim, 9 years ago. I've had some amazing vagabond adventures since. But after 9 years of boat liveaboard living, i have baught a house in Cairns. I am not prepared to leave Logic in a marina most of the time, so reluctantly i am putting her up for sale.

Remarks
Attached is Inspection report dated April 2022, by the highly respected catamaran sailer, Geoff Cruise.
The boat is well maintained, capable of leaving as-is for a circumnavigation of the globe.
I am ending my cruisng life, so Logic is walk-off/walk on. She comes with cuttlery, crockery, pots and pans, linnen, fishing gear, spear gun, wet weather gear, Phantom 4 drone, ocean gardian shark gard, paper charts for most of the east coast of Australia, cruisng guides from Melbourne to the Kimberlies (and NZ), inflateable paddle board with cardon fiber paddle and 12 volt pump, tools and spare parts.
Slipped in June 2024
I'm currenly spending October 2024 having a last hurrah cruise, up to Lizard Island and then back too Cairn
(limited reception).
Preference will be given to buyers who can take ownership before Christmas
