This boat has been in the family for more than 20 years.  Much loved with about $100k of hull work undertaken on this steel sail boat, she's ready for a new owner.  A classic gentleman's boat it would make a great liveaboard as well.

With plenty to do on this project boat, a viewing is recommended, this boat is new to the market the owners are selling as they have two sail boats in the family and are now downscaling to share just one boat between their families.  They need the berth for the other boat which is coming back to Singapore from Phuket after a couple of years there for refitting.  Te pandemic has delayed their return to their home port.

We're excited to list this boat exclusively for sale. We're helping the family to consolidate their boating assets, maximise their time and reduce their boat holding costs by selling their now surplus boat.

Survey (September 10, 2021 - ENCEE Marine Consultants)

We were given the understanding that this yacht was about 40 years old. The vessel had dry docked at Dalac Marine in Johor, Malaysia, from September 2014 to November 2015 and undergone major refitting and rebuilding.

The Owner had reportedly monitored the entire refitting and rebuilding process. After completion, the present Owner had taken the ownership of this yacht on 01 March 2016. The yacht had been registered under the company ‘De Boot Pte Ltd’.

The Owner had reportedly been sailing on this yacht with the previous Owner since 1995. He was a former national sailor and a gold medal winner in the 1988 SEA games. He advised that this yacht would be utilised mainly for pleasure trips for his family to places in Malaysia.


Mooring & Crew

This yacht had been moored at the designated mooring buoy at Changi Sailing Club. The Owner had also engaged part time crew to perform maintenance of this yacht during weekends. At times of mooring, the sailing club would keep a watch over the vessels moored there

The Owner would command this yacht himself and he had been issued with pleasure powered craft driving licence issued on 25 April 2008.



At time of our inspection, this yacht was moored at the designated mooring buoy at Changi Sailing Club. We had performed an afloat visual external and internal inspection and noted the following conditions:-



As far as could be sighted above the water line, we noted that the external paintwork of the steel hull was intact without any corrosion present. There were only some minor fender marks present at the side hull stern section. No indentation or set in of the steel hull was sighted.

As far as could be accessible, we had also conducted a visual inspection of the internal steel hull from the internal cabins. We noted that the internal bottom hull was also well painted. No set up of the inspected internal bottom hull was sighted.


Deck & Fittings

The Owner advised that the main deck had undergone some steel renewal. The steel deck had then been laid over with wooden strips, which were noted to be in sound condition without any visible defect sighted.

Constructed on the forward and stern deck were access hatches to the stern dining compartment and forward cabin. Both hatches were found to be in reasonably sound closing, sealing and locking condition.

Constructed on the forward deck was a small store compartment with two covers. Safety guard railings were also fitted around the main deck. These items were visually inspected and found to be in sufficiently robust condition.

Installed on the forward and stern deck were the sailing mast with the sails fitted in place. These masts were reported to be the originals and our visual inspection revealed that the installation on deck were in order. Internal supports were also in place on the under side of the main deck. Both masts appeared to be adequately robust without visible defect sighted.



The dining cabin was located at the stern section of the yacht while the cabins were located at the forward section. The galley was located at the midship starboard section of the vessel. Our visual inspection revealed that the furnishings were in order. All cabin port holes and covers were also found to be in reasonably sound closing, sealing and locking condition.


Engine Compartment & Machinery

The engine compartment was constructed at the midship port section of the internal hull. Our inspection of the bottom and side hull structure revealed that it was well painted without corrosion present. Sea suction cocks fitted to the internal bottom hull and overboard discharge cocks fitted to the side hull were noted to be new, without any leakage or defect sighted. There was some bilges collection at the internal bottom hull.

Installed in the engine compartment were the main propulsion engine and electrical generator set. Both were noted to be in a painted condition and maintained to be reasonably clean. Both were tested to be in satisfactory condition without abnormality noted.

During our inspection of the internal hull compartment, we also noted that each compartment had been installed with individual electrical driven submersible bilge pumps, tested to be operational.


Navigational Control

The navigational control console was installed on the upper deck, located above the engine compartment. The following equipment were installed:-

  • 1 x multi function display for chart plotter, speed and GPS
  • 1 x radar
  • 1 x wind speed and direction indicator
  • 2 x depth sounder
  • 1 x boat speed indicator
  • 1 x auto pilot display
  • 1 x VHF radio
  • 1 x compass The above equi

The above equipment were tested to be in functioning condition. Air horn was also provided on board.


Safety Equipment

Provided on board were sufficient life jackets and life buoys. Two fire extinguishers were also provided on board, which would be due for inspection by December 2016



This yacht had undergone major refitting and rebuilding, which were completed in November 2015. The Owner had engaged part time crew for carrying our maintenance to the deck and internal hull during the week end. The Owner would also perform routine maintenance of the machinery on board. From the buckets of paint and oil stored on board, as well as the condition noted, we
noted that the Owner had been performing regular painting maintenance of the hull, as
well as regular lube oil renewal of the engines.



After our visual afloat inspection of this yard, we noted that the hull had been maintained in a reasonably sound condition. Compared with our survey records about 5 years ago, the hull was found to be still in similar condition.

The navigational equipment and machinery on board were also noted to be in functioning condition. Customary routine maintenance and monitoring of the hull and machinery had been performed by the Owner. The Owner would also command this yacht himself and he had been certified by MPA to be qualified and had many years of yachting experience to do so. From our inspection this time, we had noted one deficiency and had provided the following recommendation for rectification during the vessel’s next upslip maintenance.

Judging from the overall condition, it is our considered opinion that this yacht should still be suitable for the reported usage.
