Moonraker Benefits from Re-build & Yanmar Dieles Power

When a skilled shipwright sets about restoring his own boat, chances are that the outcome is going to be stunning. In the case of Wayne Parr and his Yanmar 2GM20 18.2mhp@3600rpm powered sloop Moonraker, the six year restoration exceeded all expectations.

As a first year apprentice, Wayne Parr ‘met’ Moonraker in 1998 when she was in the yard at the Wooden Boat Shop for a new Yanmar engine. Parr’s initial reaction was that this 1953 built, 25’ boat had a cavernous interior cabin below the decks. Tim Phillips, the owner of the Wooden Boat Shop commented at the time that Moonraker was a beautiful boat that could sail anywhere.

A decade later, the owner of Moonraker approached Wayne Parr and suggested that he might like to buy the boat. Obviously, Wayne Parr had shown way too much interest in the boat during the repower. The change of ownership took place in 2008.
The first year of the six year restoration project was spent pulling the fit out apart and removing all the paint and fittings from inside the hull. This was undertaken using a heat gun and scraper while Moonraker was moored in the water. The paint removal process revealed all the faults and fractures which would later need to be rectified.
It also showed that the hull was well constructed, her full length planking in NZ Kauri was in beautiful condition. The hardwood frames however were not so healthy. With the paint peeling away, one break after another was revealed. A full year was spent repairing the frames and fitting eight new floor timbers. A new keel was also fitted with the overall strength of the hull greatly increased.

Working as a shipwright by day at the Wooden Boat Shop and then picking up the tools after work for a couple of hours more, proved to be challenging.
With a deadline of the 2015 Australian Wooden Boat Festival at Hobart, Wayne Parr was resolute in finishing Moonraker in time to make the Bass Strait crossing.
“Anyone who has built or restored a wooden boat understands that it is a big commitment financially and physically,” Wayne Parr said. “In many ways restoring
Moonraker has been more gruelling than building a new boat.”
The Yanmar 2GM20 was one thing that Wayne Parr had complete faith in and chose to leave intact. “We had installed the Yanmar in ’98 so I knew that it was in excellent condition,” Wayne Parr said.
“Because of my work at the Wooden Boat Shop where we fit and service Yanmar marine diesel engines, I have absolute faith in the Yanmar brand. Moonraker can
carry 150 litres of fuel so that’s a lot for this efficient engine.”
With Moonraker back in the water and lovingly restored from stem to stern, Wayne Parr together with his wife Melinda Piesse set off from Sorrento (Melbourne) and set course for Hobart. The plan was to take 2 ½ weeks island hopping across Bass Strait, undertaking the journey in the company of another boat.
The idyllic pre-voyage dream and the reality soon proved to be at odds with one another. The first couple of days at sea provided the dream sailing that had been
anticipated. It was peaceful travelling under sail, then at the end of each day, the Yanmar 2GM20 was started so that Moonraker could reach the overnight target
Bass Strait weather can be unforgiving and treacherous. When the weather changed for the worse, Wayne Parr knew that all his skill as a shipwright would be
put to the test. Those repaired frames and new keel proved to be a wise investment. The seas were very sharp and had a chop on top. As Moonraker ploughed into each trough, the green water would literally bring the boat to a shuddering halt. Sailing was out of the question, so the Yanmar 2GM20 was pressed into action to push Moonraker towards Tasmania.
At times, and with the Yanmar operating at wide open throttle of 3500 rpm for three hours at a time, Moonraker was making headway at just one knot. There were times when the GPS showed negative one knot speed. The 35 to 40 knot winds and high seas were pushing Moonraker backwards at full throttle.
Eventually Moonraker made it. She took the full 2 ½ weeks to make the journey and of the 17 days at sea, only two were spent under sail. The Yanmar 2GM20 ran for over 100 hours on this voyage and got Moonraker all the way across Bass Strait with a total fuel burn of 220 litres.
“We took on extra fuel at Lady Baron Island, but apart from that we were selfsufficient,”Wayne Parr said.

“Ours is a boating family and we’ve always had Yanmar engines. The voyage in Moonraker again proved that the Yanmar brand is safe and very dependable.”
In most repower situations this is where the story finishes, but not so with WayneParr. His arduous experience across Bass Strait highlighted the need to consider
more power in the engine room. This coincided with the launch of the new Yanmar 3YM30AE marine diesel engine.
“When Yanmar released the new 3YM30AE engine I thought that it would be the ideal model to upgrade Moonraker,” Wayne said.
“This is a new generation engine technically with greater fuel efficiency and more power. It will greatly enhance our capabilities aboard Moonraker.”
The new model Yanmar 3YM30AE is a three cylinder engine which develops 29.1 mhp at 3200 rpm. The maximum rated engine speed is 3200 rpm. As a result of the reduced maximum rpm and new cylinder block design, the noise and emission levels have been reduced and the engine torque increased.
The 3YM30AE having a similar footprint to the Yanmar GM series proved to be very easy to install without major works to the engine compartment. Moonraker now reaches her 6 knot hull speed-conserving fuel running, at just over 2000 RPM.
“There are numerous other benefits the 3YM30AE offers for the cruising yachtsman, such as the capacious 125 amp alternator with the no slip flat belt, and the forward facing water pump that enables an impeller change without demounting the pump,” Wayne Parr said.
“Knowing I have the Yanmar brand behind me, supported by my friends at Power Equipment who have a second to none commitment to the delivery of parts
and support, I now have even more confidence in Moonraker facing headwinds in the open sea”.
