Boat Description

The wave piercer hull form is still a relatively new concept in the 20 – 30m range and offers operators huge advantages in efficiency, sea keeping, and performance.These striking vessels also offer distinct marketing advantages for companies looking to have an edge over their competition.We are currently in the process of developing our standard specifications for commercial and private charter versions of our 21/22m and 30m wave piercer hulls. We have have the specifications and general arrangement for a 21m luxury wave piercer we recently built to survey standards for an experienced Australian owner. The vessel is long range capable of 5000 n.m. and comprise a level of outfitting and finish yet to be seen in the private vessel market. Make no mistake, this is a serious ocean going, live aboard vessel built to commercial specifications. We also have available a selection of interior photos from previous vessels both private and commercial available upon request.

Background

University qualifications in Science. Computer Science and Engineering (Naval Architecture) combined with experience in various design offices gives us great confidence in our Ferry Designs. We take great pride in the high level of performance that our designers achieve. We are orientated toward the project goals set in conjunction with both the builder and operator.

Structural design of complex vessels such as 60m Trimarans and 90m Wave Piercing Catamarans have left us with a legacy of design tools and techniques that allows us to quickly optimise our structures and target our project goals.

Tank testing as well as trials analysis of various projects gives us the confidence that we are offering extremely slippery hull shapes to our clients.

Arrangement

• The General Arrangement works around very simple structural concepts. The find bridge at frame 17 has incredible strength because of its shape and location. Aft the combination of the transverse bulwark and cabin is equally efficient and strong. With the major structural issues of catamaran design well sorted we are free to make other scantlings lighter and more efficient. It also gives those who sail on her confidence in the incredible strength of the design.

• The wheelhouse is placed well forward with its floor is only 250 mm above the fore deck to enhance the sleek styling.

• The Main Saloon features well spaced seating modules with 850 mm pitch and 550 mn width.

• The layout incorporates continuous longitudinal girders on both decks. A very open NO-pillar main cabin is achieved through careful structural design of the roof girders and frames.

• The fore deck access allows passengers safe and easy access to the spectacular views from the fore deck.

• Machinery is kept well aft to keep noise and vibration away from the main cabin. Research into engine mounting. drive train and sound insulation systems will minimise noise and vibration. The generator sets are placed aft of the main engines.

Hull Design

This design is a '2 nd Generation WPC'. When compared to older 1st generation designs significant design differences are evident.

• The demi-hulls are long with the longitudinal center of buoyancy (lcb) well aft and of minimal whetted surface area. Over the past 9 years we have been developing hull designs in conjunction with Meat Tasmania. The longer hulls give us great improvements in sea keeping and in resistance. The lcb aft allows us to maximize demi-hull length and still achieve level trim for a given General Arrangement incorporating passenger spaces aft for more comfort. Hulls with a more conventional lcb position can achieve slightly better resistance for the same length but the increased length obtained by having the lcb aft more than compensates for this. When it comes to resistance there is no substitute for length in these vessels.

The center bow tunnel shape forward have also undergone significant development. The tunnel height increases as you move forward from frame 16. The center bow has more volume low down through the introduction of 20 degr. “V” and chine. In smaller waves the center bow stays clear and the wave piercing bows do the work. In larger waves as soon as the center bow touches the water it helps the vessel ride over the offending wave. The increased bow and tunnel heights allow these 2ndgeneration WPC",, to safely cruise smoothly through larger seas without slamming. It features conventional props with mini skews built from the stem tube. The jaw design on Wave Piercing Catamarans is critical. I generation WPC designs have knuckled jaws with heavy plate inserts. They need to be continually surveyed for fatigue cracks and repaired. The new generation WPC has an organically shaped jaw with minimal stress concentration and therefore is stronger.
