Be sure to click on the photos to open the seperate photo gallery in full-screen - otherwise you only see half the photo if you flick through on this page. I've also added some links to other Mk I and Mk II Crowther Spindrift Catamarans that are sailing around the world on You Tube that an interested buyer told me about. I have no affiliation with S/V Zingaro or S/V Tula. Note - Groucho is a Mark III Spindrift with increased head room in the bridgdeck compared to these other two similar boats.

The Spindrift 37 is a Lock Crowther Design and was the prototype for the Crowther Designed Catana 38. This MK III version was professionally built by one of Australia's most respected multihull builders, Shawn Arber. A recent July, 2017 Marine Survey testifies the high build quality and structural integrity of this boat. This MK III version of the Spindrift includes 6ft standing headroom in the bridge deck galley, an extended transom with balanced rudders and quadrant wheel steering. This particular boat has a proud history and is well known throughout QLD for it's significant racing achievements, including the esteemed Brisbane to Gladstone race along with many other inshore and offshore races. The boat has been used as a cruising multihull in more recent times, however she still maintains her high performance and loves to sail fast offshore. This boat has has cruised extensively through the Pacific Islands and along the Australian East Coast.

I purchased the boat in 2017 with the intention of undertaking an extended cruising voyage with my wife and kids. I sailed the boat from Brisbane to Geelong with a couple of friends on what proved to be an amazing 1000nm trip. We used less than 100 litres of diesel over the entire journey. The boat performed very well, particularly in following seas and wind. Some days were spent averaging over 10 knots while reaching a top speed of 17.8 knots surfing down waves. Other days were calm and the old Yanmar engines kept us chugging along at 5 knots using less than 2 litres per hour. The autopilot on this boat is amazing and we hardly touched the steering wheel for days on end. Coming from a monohull background, I was blown away at being able to easily cook and eat a hot meal comfortably around the bridge deck table while 20 miles offshore with the auto pilot effortlessly steering the boat.

My family and I spent 4 weeks on the boat over Christmas cruising around Port Philip Bay and Western Port. The boat is roomy and comfortable with the lack of rolling at anchor being one of our favourite advantages over a monohull. Our only issue, and the reason we are now selling the boat, is the age of our kids at 3 and 5 years old. We have unfortunately come to the sad realisation that the kids are still too young for extended cruising and we'll probably need to wait another 4 or 5 years before they are old enough. We're in no hurry to sell the boat as we are still enjoying cruising around the beautiful sheltered waters of Port Phillip Bay as can seen in our photos. However we would rather see the boat being used by someone who's circumstances allow then to cruise offshore to slightly more exotic destinations. Groucho was built to travel far and fast in comfort and we feel we are now holding her back. She has won many offshore races, she has cruised the Pacific extensively, and she has the ability cruise anywhere in the world in safety and comfort. As with any performance cat you don't want to weigh the boat down but there is plenty of room for lots of light weight toys like surfboards, kayaks and folding bikes.

*** I have priced the boat realistically and I want to be as transparent as possible. Please read the following paragraph carefully before ringing up to enquire ***.

The boat is ready to go cruising in its current condition; we take the boat cruising around Port Phillip Bay a couple of times per month. However, the boat has all the normal things you would expect in a 40 year old boat in this price range. Older sails that are only in fair condition but serviceable (they just sailed 1500 nautical miles in the past 6 months with no issue). Older engines that will probably go forever but require the usual maintenance along the way. I've replaced a starter motor and fuel filter coming down the coast. Older style folding propellers (see engine notes below). Old electrics that work fine but require the usual 12 volt tinkering along the way. Some crazing on the old windows. Old halyards and sheets. Some bird droppings stains and the need to touch up paintwork and scuffs here and there. Eighteen month old anti foul paint (which I dive and scrub regularly to keep the bottom smooth and fast). The 2017 survey shows an insurance value of $100,000 and I'm sure this would be the case if you were prepared to spend a few thousand on making the older things newer, as she is a well respected performance catamaran. I have taken the above things into consideration when pricing the boat realistically. I don't like it when boat brokers over-inflate the price of boats in hope of a wealthy-dreamer-sale only to then relent to lowball offers at a price they should have set realistically in the first place. I am open to 'reasonable' and 'respectful' negotiation but I won't have any time for silly low ball offers or time wasters. I've bought and sold enough boats over the years to spot a tyre-kicker from a mile away so please don't bother. Groucho is a beautiful, solid old 40 foot performance catamaran and remains a pleasure to sail. Lock Crowther was famous for his timeless designs. She is easy to sail sigle handed and has simple and easy to manage systems on board. I'm happy to share more photos and information if you're genuinely interested.

As awesome as she is, Groucho is 40 years old! Hence the price. I've had a lot of enquiries from people who clearly have not read this ad. Please be realistic and don't take the time to enquire if you are actually looking for a nice shiny, polished, modern Catamaran - you'll find those in the "over $200,000" category. Cheers.

Length 11.88m. Beam 6.0m. Draft 0.9m. Dagger boards. Balanced rudders with with quadrant wheel steering and emergency tillers.

Port hull: Yanmar 2GM20 (approx 30 years old). Good, strong, twin cylinder engine. It pushes the boat along at 5 knots running solo with the other engine switched off. Some recent issues (March 2018) with the foward gear sometimes slipping when engaged; I've got a mechaninc looking into this; may just be the shift lever or worst case scenario might be a driving cone replacement. Otherwise, a solid little engine that starts first time every time and chugs along for days on end. Starboard hull: 1YSM8G (approx 40 years old) with new starter motor, mixing elbow and raw water pump rebuild in 2017. YSM8 still has the original old folding prop that sometimes takes a few attempts to fold out properly due to worn teeth and would need replacing at some stage if manouvering in tight marinas (not an issue on a swing mooring). This little old single cylinder starts and runs reliably but is a little underpowered to push the boat fast enough on its own without the other engine running (a new prop would no doubt make a significant difference). I haven't changed the propellers as my personal preference, if we were to keep the boat long term, was to put 2 x Yamaha 9.9 hi-thrust outboards in the cockpit lockers on vertical slides; half the weight but more power and bigger props - $3,500 each for brand new engines). The lockers are in the perfect position for this setup. However, I appreciate that some people love diesel inboards and don't like petrol outboards so I've left the engine setup 'as-is' for the next owner to set up their own personal preference.
