Most Luxury Yachts Design


 

It has become normal for the world’s wealthiest individuals to drop millions, even billions, on lavish superyachts.

Oil Sheikhs and Russian tycoons alike are spending their holidays on massive yachts with swimming pools, basketball courts, and even concert halls.

Scroll down to see 11 of the most expensive yachts:
 
$200 MILLION: Microsoft co-founder Paul Allen owns a 414-foot yacht dubbed the Octopus. It has 41 suites and cost a whopping $200 million to build. The Octopus comes with a pool, two helicopters, and a movie theater. If that’s not enough, there’s also a basketball court and recording studio.

Pinisi Yacht History

 Silolona Watercolor - Copyright 2002

The Evolution of an Indigenous Wooden Sailing Vessel

The "modern" wooden 'Pinisi' type has been derived from similar craft that have been in use in and around Indonesia for several centuries. According to some sources, similar types have existed prior to the 1500's, such as the Arabian Dhow.
The sailing 'Pinisi' hull form in many ways resembles a cross between two traditional American sailing vessel types, the Pinky Schooner and the Tancook Whaler, even though the 'Pinisi' hull type pre-dates those Western hull forms by centuries... In other words, in its original form the 'Pinisi' was a double ended hull type, having sharply raked stem and stern post. There was not a centerline rudder however, as with the American craft. Instead the local Indonesian craft in the past most often made use of twin rudders, one on each aft quarter.
Used both as transport and as cargo vessels, the craft we are calling 'Pinisi' (variously spelled Pinissi, Pinisiq, or Phinisi) have traditionally been built on the beach, where the logs have come from the forests of Sulawesi (Celebes) and Kalimantan (Borneo), then transported to the boat building sites.
Historically, several interesting rituals and ceremonies have been part of building such a vessel, beginning with choosing the right trees for critical parts of the structure. Just as with traditional wooden boat building in the West, various rituals continue throughout the building process to initiate and celebrate each stage, such as the all important laying of the keel.

Engines for Vessels and Yachts

The basis of the following guide is that the maximum displacement hull speed is to be achieved by a clean and polished hull in calm sea with no windage. Racing yachts may wish to opt for more limited horse power as the engine is primarily only used to reach or leaving moorings, motor sailors or yachts used in heavier seas and or tides may opt for up to 30% more horse power to ensure an adequate safety factor is available.


Engine power, rpm, gearbox reduction ratio, propeller diameter and pitch are all variables that will affect a displacement hulls performance and as a consequence is a specialist subject that for new builds, the vessels designer should be consulted. For vessels which require repowering, there are existing guidelines and or parameters that are already in place to help in making the correct replacement engine choice. The existing engine, gearbox reduction ratio and propeller performance compared to theoretical maximum hull speed for the vessel will be a good indicator on whether it can be improved or not.

Additional there may be some set parameters such as the distance between the centre line of the vessels propeller shaft and the hull that may or may not allow a larger more optimised propeller to be used. If the propeller`s diameter is restricted, this can in part be compensated for by changing the propeller pitch, but there are limitations. For more detailed information on propellers visit Propeller Options.

  • A general engine guideline for yachts with a displacement hull is the weight in tonne multiplied by 4 hp.
  • Theoretical maximum displacement hull speed in Knots = 1.3 (or 1.4 for a sleek hull) x √ Water Line length (in feet).

Yachts and Vessels Engine Guide

When it comes to a yacht engine, expert knowledge and care is required to achieve optimum performance for cruising through the waters of any ocean. With guides on both the engine essentials and maintenance of machinery, Yachting Pages presents guides to getting to know your superyacht engine.

 Superyacht engine essentials

Superyacht engines, like all marine engines, are large and complex pieces of machinery that come in all manner of shapes and sizes. Aimed at new superyacht crew and general engine enthusiasts, Yachting Pages’ guide presents an introduction to yacht engines, covering all the essential areas from yacht engine sizes and the different types available, to what to expect in the engine room.

How to get the most out of your yacht engine

Overhauling a marine engine can be a costly and time-consuming job. Taking those extra steps to properly maintain your superyacht engine can therefore offer thousands of extra hours of work before an overhaul is required. Yachting Pages explores how to protect and maintain your yacht engine, in order to get the best possible performance out on the water.

Overview of Yachts Engine

Engines can be referred to as the beating heart of any motoryacht; responsible for getting a vessel going and keep it running through ocean waters. Yachting Pages explores the essentials of yacht engines for crew wanting to work in the engine room or for general engine enthusiasts, with help from John Warren at Premier Separator Services and Jean-Francois Conso from Conso ETS.

Yacht engines: Does size matter?

As can be safely assumed, an engine for a 40ft yacht is not going to be the same as that of a 40m superyacht in terms of size, weight, power or complexity.

While engines for smaller yachts are technical in themselves, superyacht engines in particular are “extremely complex”, as John from Premier Separator Services explains, “On board a superyacht you have so many systems other than the main engine, from the auxiliary equipment and generators, to the air conditioning and sewage plant. In principle, the main difference between a yacht and superyacht engine is size, but superyachts are so much more complex and very efficient if maintained properly.”
Types of yacht engine

As Jean-Francois Conso from Conso ETS points out, “There are many engines ranging from six cylinder to 16 cylinder. There are also many brands, from MAN and MTU to Cummins, Deutz, Cat and Baudoin; however the most popular are MTU and Cat. These tend to be seen on board yachts ranging from 80ft to 80m long.

In terms of fuel, diesel tends to be the preference for yacht and superyacht engines and as technology has evolved, so diesel has become cleaner and engines are able to produce more power without burning more fuel.

However, diesel is not without competition, as alternative fuels such as liquid natural gas (LNG) look to compete and provide a ‘cleaner’ fuel source for the future. If you’re interested in learning more, take a look at our investigation into the benefits and drawbacks of LNG.


Keeping your yacht engine efficient

Of course, like any engine, maintenance is absolutely essential to keep a yacht engine running smoothly at full power. Jean-Francois recommends using your engine at 80% of its full power for optimum performance, and following all maintenance recommendations from professional engine service suppliers.

25 great design of yachts

Every year at yacht shows around the world new, edgy concepts are released as enthusiasts, designers, and people with really deep pockets look on hoping to catch a glimpse of something that stirs their souls. Unfortunately, just like in our list of 25 of the world’s coolest concept cars, most of these models will never make it too market. Even if they don’t though, they’re at least fun to look at and in the worst case scenario you’ll still end up with a  list of 25 ridiculously cool concept yachts.

Moonen 124' Trideck "Northlander"

And my, what a pretty yacht she is. At first glance; Elegant. Clean and crisp. Inside, look for more unexpected creativity. She adds an ultra-modern exclamation mark to her “typical Moonen” lineage; joining an exclusive “club” which features outstanding, award-winning quality. Yet, so far has limited its production to only three or four excellent yachts per year. Since 1981, that includes some 75 yachts up to 124’ – cruisers, explorers, fast yachts and displacement yachts, in both steel and aluminum.

Designer Rene’ van der Velden, with Art-Line Interior Design’s Marilyn Bos-de Vaal and Frank Pieterse, contrived the new yacht’s highly individual, sometimes ultra-modern interior, resulting in a tailor-made expression which reverberates throughout. Featuring top-echelon comfort protocols in the Owner’s apartment, she presents four suite-caliber guest staterooms; three decks and complete, up-to-the-minute mechanical, control and navigation systems making Moonen's largest build-to-date... a first-class yachting statement!
Well regarded for compelling attention to seakeeping, Moonen builds into this new steel displacement hull with aluminum superstructure – the essential characteristics for maneuverability and stability - a low center of gravity. Complementing today’s materials with decades of Dutch yacht building experience, Moonen adds intimate attention to a ship's seaworthiness, resulting in a reputation for pocket-sized yachts that hold their own in superyacht seas. With an economical cruise of 9 knots and a storm skirting speed of 14 knots, Northlander is capable of seeking each point on a compass rose within 5,000 nautical miles. On the subject of seeking new waypoints, let's get fiscal... Merit AS of Istanbul, Turkey, recently acquired an 80% share of Moonen Yachts. The remaining 20 percent is owned by Emile Bilterijst, who continues to lead the company as Managing Partner. This move will undoubtedly lead to new horizons for the builder, as well as new working relationships. Welcome Salim!
