In September of 1996 Sabre Yachts announced plans to build a new Jim Taylor designed, 45 foot world class sailing yacht. Sabre 452 News follows the progress of this new and exciting design.
ALL THE POWER YOU NEED:
In recent years you may have noticed a trend toward larger sailboat auxiliary engines. Until recently, the concept of a putting a 72 horsepower diesel engine, in a 45 foot sailing yacht displacing from 26,500 to 33,000 pounds, seemed like overkill. (By the way when we quote this weight range it is not because we don't know how much she will weigh: we do. What we don't know is how the yacht will be used or what gear might be carried on board. In "IMS measurement trim" the design will weigh in at the low end of the scale but fully equipped for an extended cruise, with generators, air conditioning and so on, she may weigh as much as 33,000 pounds.)
Today, the engines of sailing yachts of this size are being asked to do more than simply propel the yacht through the water at a reasonable speed. It is quite likely that Sabre 452's will be equipped with engine driven refrigeration systems, extra alternators and in some cases, generators which can offer AC power from the yacht's main engine. All of these devices consume horsepower and as a result the engines must provide more.
On the engine manufacturer's side, advances in diesel engine technology have been steady. Today, a relatively light and physically small, turbocharged diesel engine, can provide a lot of power. Standard power on the Sabre 452 is the Yanmar 4JH2-HTE. Optional engine types are available on request. A decision on engine type should be based on personal experience, dealer recommendation and service availability in both your home cruising grounds and your intended destinations. Choose a company with a strong reputation for quality and service.
PEACE AND QUIET:
The topic of engines naturally leads to the topic of noise and noise suppression. Noise is a simple issue for most sailors: They don't like it!
An additional advantage of the larger horsepower engine discussed above, is that the yacht can be driven to it's cruising speed at a relatively low engine RPM. Lower engine speeds mean lower noise levels.
Sabre's experience with noise suppression is extensive. If you have read any of the articles written about our Sabreline motoryachts you will know that our motoryachts are amongst the quietest available. Working with Soundown Inc. of Marblehead, MA, we made the Sabreline 43 one of the quietest yachts around.
On the Sabre 452 we begin with the engine mounts and eliminate as much "pass through vibration" as we possibly can. We have allowed a full 2" of space around the engine to place a two pound density, foam/lead liner in the engine box. In addition, since sound is dampened considerably when it has to go around a corner, all openings to the engine compartment are framed and the access panels inserted into the frame to minimize sound escaping from the box.
Noise and vibration abatement is a "work in progress". As we get further into the prototype, we'll have more to add on this topic. Rest assured that this is a priority and that we intend for the Sabre 452, to be as quiet and as vibration free as it can be.
VACUFLUSH TOILETS....AN END TO ODORS:
It goes without saying that one of the most annoying things about boating is the odor which comes from water sitting in the bowl of the toilet. On the Sabre 452, we are going to address this problem.
The Sealand Vacuflush toilet is available as an option on most Sabre yachts. This toilet is standard equipment on our larger motoryachts, the Sabreline 43 and 47 and is operating virtually trouble free in service. The Sabre 452 comes standard with a Vacuflush toilet installed in the owner's head. (This head compartment also features a ceramic sink and tiled floors. Very classy stuff!)
The concept of the Vacuflush is that a pump and reservoir provide vacuum pressure so that when the user depresses a foot switch, the built up vacuum pressure flushes away the effluent. This unit is plumbed to the fresh water supply and uses uses a minimal amount of water with each flush. The result is a toilet which operates odor free. But the best news is that the user no longer has to judge when enough water has been flushed through the system to completely evacuate the hoses.
In a perfect world a standard marine head is pumped the appropriate numbers of times and a minimum amount of flushing water is moved to the holding tank. It's all guess work on the part of the user. But under normal circumstances, the head is either flushed too many times, which fills the holding tank with "flushing water", or not enough pumps of the handle are applied to get the effluent through the hoses, which may ultimately lead to blockage and a nasty mess. The Vacuflush is like having your head on "automatic".
In a newsletter, there always seems to be a little bit of space leftover at the bottom of the page. Similarly, in a sailboat, every little bit of space can be used by a good designer. On the deck of the Sabre 452 we elected to offset the companionway slightly in order to provide an adequate space for the aft head and a suitable passageway door to the aft cabin. In order to minimize the visual effect of this offset in the deck tooling, designer Ken Rusinek created a nice storage space to starboard of the companionway slider which is deep enough for a winch handle and can hold everything from a bottle of sun block to sail ties and a rigging knife. A great use of leftover space don't you think?
WORK BEGINS ON HULL #1:
In mid-July, work began on laminating the first hull parts for the Sabre 452. The first hull is a flag blue boat with a traditional transom. The hull of the Sabre 452 uses a 3/4" balsa sandwich core which provides superior stiffness and weight characteristics to the design. The Sabre 452 has balsa from gunwale to gunwale with a section of solid glass running down the boat's central "spine". The coring material is held back wherever standard and optional thru-hulls will be located.
Cruising sailors will benefit from the cored hull as the coring material provides both sonic and thermal insulation as well as it's primary benefit of added stiffness. In the heat of the day in the tropics or on cool nights cruising the Alaskan coastline, count on balsa coring to provided a quieter, warmer boat with minimal condensation on the interior hull skin.
SABRE YACHTS IN THE SCHEME OF THINGS:
Both a traditional and a step transom are available for the Sabre 452. Although this involved building two separate transom molds, we felt that we wanted to offer both choices to our clients. This demonstrates our commitment to offer our clients the ability to "order it their way."
There is without question a fine line between custom yacht building and the "agile manufacturing" system which we employ today at Sabre Yachts. We like to think of it as "personalization" rather than "customization". What that means to the consumer is a quality comparable to the most expensive custom built yachts, but at a considerably better price, brought about by our higher volume of production and the size of our dealer network. It does however force our customers to make their choices early in the game so that we can schedule the boat as our system demands.
In 27 years we have built over 2,000 fine sail and motoryachts. We have been unrelenting in our commitment to offering the highest quality at the most reasonable price. Our current market status and strength indicate that the Sabre brand is in perfect health and looking forward to a long and healthy life.
CARBON FIBER RUDDER STOCKS:
Perhaps more than any other boatbuilder, the styling of Sabre sailing yachts has remained consistent over the past 25 years. Certainly, subtle changes have been made as yacht design has developed and styling has varied with the times. What has changed significantly at Sabre, is a lot of the materials which you cannot see from day to day. These are the items which create the reliability and quality for which Sabre has become so well known. They are the component parts and materials with which we build our yachts.
With the design of the Sabre 402 in 1996, we decided to go with a carbon fibre rudder stock instead of a stainless steel stock which had been our traditional build for over 25 years. The decision was a very good one and all of the Sabre 402 rudders are performing flawlessly. The Sabre 452 will also sport a carbon fibre stock. The advantages of this new material are increased strength at a lower weight and resistance to corrosion.
The weight of the rudder is an extremely important factor for those who wish to go bluewater cruising with their boats as most 452 owners will do. A carbon rudder weighs approximately 120 pounds less than a stainless stock rudder. Imagine a 120 pound weight hanging on the aft end of your boat. As she pitches over waves, the 120 pound weight compounds the pitching moment of the boat considerably. Simply put, not only is carbon a stronger, safer material, it will make your boat ride a lot more comfortable too. And, the less pitching you do, the faster the hull moves through the water, so if performance is a priority, as it tends to be with Sabre owners, carbon helps there too.
The Carbon Fibre rudder stock is a wonderful example of how technological advances, developed mainly on the race course, can benefit both the cruising sailor and the racer alike.
TEAK GRATES FOR THE SHOWER COMPARTMENTS:
We originally announced ceramic tiled flooring in the forward shower and in both head compartments of the 452. We realized after making that statement that the floor of the shower would have to be aggressively sloped in order to create good drainage, especially so when the boat is heeled and sailing offshore. Feeling that this sloped floor would be uncomfortable to transit when the yacht is level, we opted for a teak grate which provides the optimum drainage for the shower and level footing at the dock or anchor. We feel it is by far the best solution.
We have retained the ceramic tile floor in the head/sink side of the owners head compartment. You'll be pleased to know also that the sink in the forward head is a Sealand ceramic head which matches the ceramic bowl of the Sealand Vacuflush head unit. Very elegant! The forward head compartment also boasts a laundry hamper outboard of the sink.
The aft head, which serves both as a day and guest head, also boasts a shower although this one is not in a separate stall. Direct access to this head is provided both from the main salon and the aft cabin.
