Another TY 620 plus TY 520 moored in Singapore.

 


 

Hi Bruce,   we have just had a great New Years in Singapore. We had a party with TY620 and TY520 rafted up. Another TY520  also in the bay. Roberts designs well represented here in Singapore. Our Ty520 cruises at 7 knots with a 267Hp John Deere single engine at 1500 rpm and using 10 litres/hr. Rod Steele’s TY620 when it matches our boat at 7knots with twin 230 Hp John Deere at 1200 rpm and using 15 litres/hr  (bigger boat and twins)

I have found with our boat that the engine/gearbox/prop have worked out really well. We can get full revs and a good performance so they are all nicely matched. Mel and I are really enjoying life on our TY520. It is a great size for two to live on and everything we had dreamed of.   Regards Al and Mel Dow

Voyager TY 520  Kit or Cutting files
Developed from our proven Trawler range - This kit is for the serious cruiser or 'live-aboard'.  The displacement hull is capable of cruising at around 8 to 14 kts depending on horsepower of the engine(s). This design is well suited for extended cruising  in   luxury.  The standard version has side decks however we can arrange other versions with either single side deck or with full wide-body salon.
 
These trawlers are designed in accordance with Lloyds  for category 1 (unrestricted operating / sailing area), which is much better than the EU and other Classification Societies and the  CE-A require. Complete stability calculations to USCG offshore requirements are included in the design package. All calculations are also cross referenced against ABS requirements to ensure that the design meets world-wide standards and specifications.

In the case of KITS, all plate parts belonging to the hull, deck and superstructure that are accurately cut to size are included. The parts are marked with the appropriate part number and engraved matching marking lines to assist in the assembly and location of the part in its position. Cutting method is Plasma / Oxygen, ensuring highest accuracy and smooth edges.
 
Plate parts are cut from Lloyds approved A Grade Shipbuilding quality STEEL that has been coated with factory applied Sigma weld MC welding primer.  We use and recommend steel plate that has the official designation ISO standard 10474 or EN 10204 with 3.1.B certificate.
TY 620 - Bruce,  I had reply from ROYAL YACHTING ASSOCIATION on the plan evaluations. They have been very quick and say they have no concerns about suitability for Design category A (unlimited offshore).  They made a nice compliment on the quality of your plan information.

September 2012

Dear Bruce, we have lived aboard our TY520 for over two years now and have travelled around 3000 miles around Singapore, Thailand, Malaysia and Indonesia. We have a single engine John Deere 6068SFM50 rated at M4 2600rpm and 267Hp.  In good conditions we have reached just over 10knots max but our cruising speed for comfort and economy is 6-7 knots.  At 1200 rpm we can achieve 5 knots and burn around 6 ltrs/hour  At 1500 rpm we can achieve 6 knots and burn around 12 ltrs/hour  At 1800 rpm we can achieve 7 knots and burn around 24 ltrs/hour

We have the capacity to hold 8000 ltrs. Had I realized how economical the John Deere was I would have cut capacity back to say 6000ltrs.

The engine room on the TY520 is fantastic. Sea Crest Marine in Bangkok did a great job in designing the layout. We have 2 x 2000 ltr tanks on either side and down the centre line there is the John Deere/twin disc gearbox, 17.5 Kva Onan Genset and a large Coltri Sub Dive compressor. Beside the compressor at the rear of the engine room there is a 50Hp Yanmar for Hydraulics. This runs the bow and stern thrusters and anchor windlass. There is a separate hydraulic pump on the John Deere for auto pilot and power steering.

There is plenty of space to walk around the John Deere and Genset with about 1.75 m headroom throughout the entire engine-room. Six 200amp house batteries plus starting batteries for John Deere, Yanmar and Genset are all under the checkerplate flooring in Sea Crest Marine custom made ventilated battery boxes. We have a 24v system.  In the lazarette  we have washer/drier, chest freezer and a workbench with lots of storage for tools and dive gear.

We have found that the TY520 is about the perfect size for our lifestyle. There is a huge amount of space on the top deck for entertainment and barbecues. The pilot house is enormous with 2.3 mtr ceiling. The 3 cabin 2 head layout is ideal for trips and friends staying in the Marina.

Very happy with our choice of boat and thank you for the support and help over the years.  Always happy to help/advise potential builders in this part of the world.   Warm regards Al and Mel Dow (Singapore)

This is what we wanted our TY 520 to look like !
 

AT LAST THE REAL THING !

Voyager TY 520 Kit or Cutting files

DEAR BRUCE,  IT'S BEEN A LONG TIME SINCE OUR LAST COMMUNICATAMARANION. WELL IT HAS BEEN VERY BUSY INDEED  BUT FINALLY OUR TY 520  "ANEMONE"  JOINED THE SEAS  ON 28TH OF AUGUST AND WE SAILED DOWN TO BODRUM FM ISTANBUL IMMEDIATELY. WE HAVE BEEN ENJOYING HER EVER SINCE, WE ALREADY HAVE MORE THAN 2000  MILES ON OUR LOG !

SHE IS A FANTASTIC BOAT, STEADY, WELL BALANCED, VERY COMFORTABLE , SEAWORTHY AND BEAUTIFUL. EVERYWHERE WE GO PEOPLE COME AND EXPRESS THEIR ADMIRATION.

"ANEMONE" IS  A  GREAT TRAWLER,  FIRST OF ALL SHE IS A REAL TRAWLER; EVERYWHERE WE GO PEOPLE COME AND ADMIRE  HER, ASK FOR OUR PERMISSION TO TAKE PHOTOS.

SHE IS NOT ONLY BEAUTIFUL BUT ALSO A VERY TRUSTWORTHY BOAT IN ALL RESPECTS.  WE  WENT INTO FORCE 7  WINDS AND SEAS, NO PROBLEM  SHE CAN HANDLE MUCH MORE VERY EASILY.  WE EXTENDED THE FLY BRIDGE PRO RATA WHICH ENABLED  US TO PARK OUR TENDER  (  4,30  MTRS ) AND A VERY COMFORTABLE SITTING CORNER FOR  MORE THAN  6  PEOPLE.

I PLACED A VERY SUFFICIENT KITCHEN ON THE BRIDGE THUS  THE LIVING BECAME ENORMOUS, NEARLY 20 SQM. I ALSO ADDED  A  HUGE  STORAGE BOX ON THE FORE DECK, IN FRONT OF THE PORTUGUESE BRIDGE  WHICH IS ALSO A VERY COMFORTABLE SETTEE. UNDER THE DECK WE MANAGED  TO PLACE 1 MASTER CABIN AND 2 REASONABLE GUEST CABINS  ALL WITH ENSUITE HEADS AND SHOWERS. 

THE  FIRST PLATE WAS TACK WELDED ON AUGUST 3, 2006  AND WE SLID HER DOWN TO THE SEA ON THE 18TH OF AUGUST 2007. SO IT TOOK US 1 FULL YEAR TO FINISH HER COMPLETELY I.E. ALL SYSTEMS INSTALLED, ALL FINISHING DONE.

THANKS ONCE MORE FOR YOUR SUPPORT AND  BEING SUCH A GREAT DESIGNER.  KIND REGARDS, ALI

Hi Bruce, Thought it was time to send an update. The TY 520 is a week away from completion of the major  welding and still looks quite fair....we have followed your instructions to the letter!

We are taking a bottom mold which can be extended from the 36' CATAMARAN for future use. Just about the only way I will get anything profitable from that job. Regards,

FROM BUILDER: Hi,  By the way, the TY 620 - 62 foot trawler yacht of Bruce's design that we are currently building is coming along very well.  

The quality of the kit parts are the best we have ever seen, and as a result, we are saving time in the build. At present, we have 9 welders/fitters working on the boat in three teams.  We have almost all of the plate hung in place and tacked up. 

We anticipate the seam welding will start within a few weeks as there are some details to attend to.

But we must say again, that we are very happy with the kit quality.  Hope to hear from you soon ....Brian

 

JANUARY 2010

Bruce, Sorry for not having been in touch for so long it has been a very busy year for Tina and I. 

Anyway our boat is moving along really well and your cuttings files work perfectly  the builder had no problems at all, we are now at the outfitting stage so in the next week they plan to move her out of the building shed to blast and paint the hull and superstructure, internally the insulation is now complete and they are installing the first of the woodwork,  the carpenters employed by boats and Boats are all ex Grand Banks people who where laid off when they closed in Singapore so the quality of the workmanship is first class, they also have their own in house design team so it has been great to see our ideas turned into reality.

If all goes well we are still on schedule to complete the boat around March and if we can complete the inclination and sea trials in time we may try and get the boat into the Singapore boat show. Mainly of the main systems such as the steering , hydraulic thruster are all class approved commercial systems which have actually worked out more or less the same price as the yacht equivalents anyway,  Dave and Tina Anderson.

TY 520 - BUILT FOR AL & Mel Dow - now based in Singapore

Hi Bruce, SeaCrest Marine in Bangkok were excellent to deal with. When we left Bangkok we had a sharp 2 metre wave right on the bow for the first 36 hours, quite the opposite from the big following seas that we experienced bringing Rod Steel’s Trawler Yacht 620 down from Korea. The TY520 handled the waves very well indeed. We had a problem with the Auto Pilot hydraulics and had to hand steer for the whole 36 hours so we would have known if the boat was not performing !

Towards the end of the 36 hours as we closed in on the Malaysia / Thai border the seas swung around about 30 degrees from head on and we were still handling things pretty well. No doubt the boat would be improved with Stabilizers but we always felt safe.

We have power steering and the boat really responds well. I am very happy with the way it manoeuvres. Stats wise we have….Single John Deere 267 Hp and we were cruising at 7+ knots using around 15 litres an hour at 1500 rpm. Very economical. Twin Disc Gearbox and 4 blade prop, Onan 17.5 KVA Gen set, 8000 litres of Fuel giving us arrange of around 3000 miles, Yanmar 40Hp for hydraulics. We have stern and bow thrusters and Lewmar windlass all hydraulic, Raymarine Radar and electronics, 2000 litres fresh water, Coltri Sub Dive compressor,

I have attached some pictures of the Sea Crest Pilot House and Engine room. They did an excellent job. We arrived in Singapore just as they were having their National Day celebrations so we got some good pictures! Very Happy to be back in Singapore and Very Happy with the boat Bruce.
Regards Al Dow
