Celeste Coupé

noreply@blogger.com (the editor) — Fri, 11 Dec 2009 11:03:00 +0000

CELESTE Coupé

This yacht is conceived for 2 persons cruising. Her home port is near Cannes, in the south of France.

She is genuinely built for two. There are fewer berths than you will see in any similar size boat. The idea is that two persons will be able to stay onboard in comfort for long periods of time.

At the same time, her owners are generous people, the open interior is lovely for friends and family and her galley is laid out for keeping everybody happy.

She is at the same time generously inviting, and cosily private.

But being built for the Mediterranean, the focus is on deck. There is room for all in and around the cockpit and her nearly-flush deck is vast for sunbathing. With her transom folded, her cockpit extended and the swimming ladder in the water, she is a perfect boat for a day sailing off the French coast.

Unusually for a yacht of such moderate size, she was built as a one-off by Fantasi Yachts. Project management by Celeste Yachts. Celeste Yachts started in 2005 with the plan to produce exclusive yachts in small series – one-offs like the present yacht, or production yachts with a very high degree of customising.

The present yacht is the first introduced under the Celeste name, called Celeste Coupé. She is painted with Awl-Grip in the trademark Celeste colour.

At first glance she is an unassuming yacht, and relatively small by today’s standards. But featuring a highly sophisticated hull shape, perfected in collaboration between Heyman Yacht Design, Chalmers Institute of Technology and the tank test facility in Göteborg, SSPA.

This hull shape is all about two things: Performance, and Handling

PERFORMANCE

With her sharper than normal entry, she has a better speed than boats of comparable proportions. In a world of uniformity, the difference is vast. VMG (speed to windward) is better by 4-5%.

Her handling is magic. She stays on track with a finger on the wheel even when pressed hard. Let go of the wheel and she slowly heads up. Grab the wheel, swing her around at full speed and she turns like a go-cart. Bear away, and her rudder has a firm grip at all times. Go forward or backward under engine and turn her around corners in crowded ports.

With her sharp, buoyant bow she has an easier motion than other boats. And, oh yes, she is dry too.

Then there’s the rig.

The sail plan of Celeste Coupé is conceived for fluky summer winds in the Mediterranean, and is almost 19 metres high. The spars are carbon, by Marström, Sweden. Sails by North. In addition to the 3DL main and non-overlapping jib there is a code zero and a gennaker.

Sailing upright makes a difference, both for speed and for comfort. There are two spare water tanks for cruising, 370 litres each. These happen to be positioned low to port and starboard, near the widest part of the hull, under the forward part of the cockpit. Fill one if you need the extra litres, shift the water to windward if you like. You activate the pump via two push-buttons from the steering pedestal and there are gauges each side so you can monitor the windward tank filling.

The effect is equal to 3 persons on the windward rail.

Celeste Coupé is not really designed for racing, she is a little too elaborately built and extensively equipped, and she only draws 1,84m (6 feet). But you never know; her owner is a racing aficionado and had some success with his last boat in Copa del Rey. The Coupé has good potential, especially in light or medium conditions.

BUILD
Hull and decks are built of mulitidirectional glass and Vinylester on a Divinycell core. Beams and stringers combine with cored bulkheads and the outboard edges of interior details to make up a rigid monocoque structure. The keel fin is solid glass and the rudder stock solid aluminium by Jefa, Denmark.

The deck is covered with 8mm vacuum-glued teak. The interior carpentry is a masterpiece made of lovely unstained Honduras mahogany.

DECK LAYOUT

The Celeste Copé has an open transom. But for longer passages, like to Corsica or Mallorca, one might prefer it closed. Thus, it is both. When the transom is folded down it forms a longer cockpit floor, and concealed at the aft end is a the swimming ladder. The open transom is also ideal for stern-to docking, Med style. There are both lower and upper handrails to make boarding easier.

The steering pedestal holds controls for shifting water to windward, for the Selden electric jib furler and the anchor windlass. The instruments and plotter are all Raytheon. For shorthanded sailing, the Andersen electric primary winches are used both for the jib and main sheets. There is no traveller for the main, just a single block. Forward of the secondary winches there are two small drained lockers for all ropes.

The yacht can be handled entirely by the helmsman (thereby of course referring to helmswoman as well but this word is perhaps a little awkward) and the cockpit seats forward are meant for spending time together, reading, eating or watching the stars.

INTERIOR LAYOUT

The Celeste Coupé is laid out for two persons. Apart from the w.c. / shower, the entire yacht is like an open studio on the water. You can overlook the accommodations from wherever you are inside the boat.

The galley has an electric cooker with a ceramic top, and the microwave has an oven setting as well. Less ideal perhaps for cooking at sea, but who wants to do that during summers in the Med? The fridge / freezer is both front- and top opening for access.

Forward of the bathroom is a dining table and a comfortable L-shaped sofa. Opposite, you find the office. You can pull two linen curtains (Josef Frank, Svenskt Tenn) to close the sleeping compartment off

The berths have spring mattresses from Madrassfabriken, Gothenburg. Forward under the flush decks is a little ‘dressing room’ with hanging lockers and lockers with shelves behind mirrored doors.

The air conditioning works in reverse cycle for heating as well. This installation is obviously most convenient for harbour use but, under anchor, can be powered by the generator as well.

INSTALLATIONS

The Celeste Coupé has a little dedicated engine room for the 40 hp Volvo Penta main engine, the 3,5 kW generator, charger and inverter, the air conditioning, fridge & freezer compressors, sea cocks, pumps and filters, a day tank for diesel and the special pump installation for shifting fresh water to windward.

Under her Volvo engine the Celeste Coupé is silent and powerful. She leaves the dock in forward or astern with equal ease, turns around in her own length and accelerates with a whisper.

Her ballast tanks are to the sides of the engine room, under the cockpit lockers. There is stowage aft each side of the steering wheel for safety equipment, shower and diving / swimming gear.

Forward, the deck locker is big enough for a tall person to enter. The Lewmar windlass stows 60 metres of chain into a separate high-and-narrow chain locker and the 15 kg stainless steel Bruce anchor stows securely in the bow platform.

UNDER SAIL

The Celeste Coupé handles like a breeze. She is course stable and requires very little attention on the wheel. The aluminium steering wheel controls the Jefa rack-and-pinion system for a superbly sensitive steering. Her steering feels like a precision instruments giving that sensuous sensation of total control with only a gentle touch, and she reacts like a dinghy.

In addition, she stays in full control and should not be possible to provoke into a broach.

Her speed, we believe, is very competitive for her size.

57' Fast Cruising Yacht

noreply@blogger.com (the editor) — Tue, 24 Nov 2009 14:18:00 +0000

CONCEPT

This yacht was meant to be something special, but without making too much fuss about it. She was built on Tjörn, an island on Sweden’s rocky west coast. She may bear superficial resemblance to Hallberg Rassys and Najads which are built on the neighbour island, Orust.

But on closer inspection, she is rather different.

In terms of two things, she is a challenge to any similarly sized cruising boat: In comfort, and in speed. Period.

During five summer seasons, having logged more than 15 000 Nm, quite a few boats have had the privilege of seeing her transom but she has not been overtaken once. The best attempt so far was from an ex-racing 12 metre America’s Cup yacht. The two yachts were sailing close-hauled in 12-15 knots of wind – no bad conditions for a twelve – but, little by little, the twelve was eventually left behind.

Being designed for the Baltic and the North Sea coasts, this yacht also has a shoal draft keel. In order to protect her crew from the cold during early spring cruises, her cockpit is sheltered by a windscreen which is a common feature on boats up here. She even has a centre cockpit. But the similarities with some other Orust boats ends there.

HOW DO YOU SHAVE OFF 10,000 KGS?

The 57’ One-Off is relatively light at 20,000 kgs. This is an essential part of her performance; if she weighed 30,000 kgs which can be considered normal for the size and kind of boat, she wouldn’t be such a flyer.

So, How?

In order to be light, a yacht has to be designed light. With her carbon rig, just enough lead in her bulb keel, and the boat built like a monocoque, a one-piece construction, she weighs less. In places where ordinary boats are assembled out of big parts glued together with big flanges, for example in the hull-deck joint, this yacht is made in one piece. The laminates are hand rolled to a very high fibre contents, vinyl ester is used throughout together with e-glass. A foam core is used everywhere except in some highly loaded areas like the keel area.

The result is an immensely strong, moderately lightweight yacht.

COCKPIT

The 57’ One-Off is a centre-cockpit yacht. Nothing much to discuss except that, generally speaking, I am not a great fan of centre cockpits. These are usually too far forward and too high up in the boat, and so will make you feel exposed. They are usually too small too, typically only 2 or 2½ metres long and without enough room for the helmsman’s seat or a big wheel.

In this design, the two big aft cabins required a centre cockpit. So how bad is it?

It is 3½ metres long. There is a helmsman’s station aft, spanning the full width of the cockpit. It is easy to find a position on the windward or leeward coaming. The helmsman’s seat is a little higher and visibility is excellent. At the helm, the floor can be raised so it works fine for shorter helmsmen too. All the sheets and trim lines are close at hand so the boat can be sailed single-handedly. The winches, the twin headsail furlers and the bowthruster are all electric and controlled by the helmsman.

The forward seating is long, with curved seats and comfortable backrests. This is a layout for leisurely sailing, sleeping, reading or watching the stars on the ocean… Or for dining, in which case the flat surfaces either side of the entrance are perfect for serving!

ON DECK

There is a sizeable lazarette locker aft and a forward deck locker. The forward locker has a shallow part, with its own flush hatch, so the docking lines inside will always be easy to reach. In the cockpit coaming aft is a dedicated space for the life raft. Walking around the decks of the 57’ One-Off boat is comfortable and safe, with well-placed handholds.

GOING BELOW

As you enter the main cabin, there are is a wet locker directly to port of the staircase and on top of this a shelf for cameras, sunglasses and books. Turning aft on the port side, there is a big-sized chart table with a ‘coal-locker’-style chart stowage beneath. The Baltic can be blistering cold in early spring, so further aft of the chart table, there are a couple of more lockers for outdoor gear.

On the starboard side of the entrance is the heart of the yacht. By heart, I mean the galley. And this galley is very special, because the owners of the 57’ are keen cooks. Not just the kind who read recipes and carry all the latest gadgets, but they do cook. Real food. This galley doesn’t have a microwave.

The fridge is arranged with two huge drawers, facing aft. Dry storage in two equally big drawers, facing forward. The freezer under the worktop on the inside of the galley. Above the sinks a drying cupboard. Lots of space and drawers. A wine cellar under the floorboards. Under the opening port into the cockpit, there is a big coffee machine which grinds and brews fresh coffee.

The galley and navigation connect forward into a pleasant main cabin. There is a pair of Bruno Mathsson armchairs on the starboard side and a dining table to port

The interior is finished in unstained Honduras Mahogany, with white panelling on the hull sides, the bathrooms and underside of the deck also painted white. Directly onto the laminate, with no excessive weight. Knowing this, the super smooth paint finish must be seen to be believed!

There are two equal, mirrored aft staterooms each laid out with a very generous double and a single extra sea berth or berth for a friend. These staterooms share a bathroom. There is a washing machine and a separate

shower stall

Forward, the owner’s stateroom also has a big double and an extra single berth. There are a number of good hanging lockers and clothes drawers, all lined with unfinished cedar. The bathroom is split; to starboard a small head, to port a bigger shower room.

MACHINERY

The volume below the soles allows an efficient positioning of batteries, tanks and engine in the centre of the boat. The 57 has a dedicated machinery room, sound and vibration insulated, accessible from opposite the navigation station.

CELESTE Coupé

Denna båt är avsedd för 2 personer och kommer att seglas i Medelhavet, med hemmahamn på Franska kusten, nära Cannes.

Hon är byggd som en one-offbåt, i ett exemplar. Konstruktör är Gabriel Heyman, Heyman Yacht Design, Göteborg och båten har färdigställts hos Fantasi Yachts, Källviken, i Nordströmmarna. Projektledning Celeste Yachts.

Celeste Yachts grundades 2005 för att producera exklusiva båtar i små serier – enstycksbyggda som denna eller seriebyggda med hög grad av kundanpassning.

Den båt vi presenterar här är den första båten under Celeste-namnet och vi har kallat den Celeste Coupé. Ytligt sett en ganska anspråkslös båt, inte ens särskilt stor med dagens mått, 36 fot. Men med ett avancerat skrov och bättre VMG än vanliga moderna båtar med identiska dimensioner.

Men så är det ju riggen.

Väder, vind och vågor är ju inte desamma överallt. Riggen på Celeste Coupé är anpassad för lätta vindar i Medelhavet, 19m hög, handbyggd i kolfiber av Marström.

Stor och fock från North, 3DL. I lätt vind en code zero som hissas från det integrerade peket.

Båtar går fortare och bekvämare om de kränger så lite som möjligt. Under främre delen av sittbrunnen finns två tankar för färskvatten på nära 400 liter styck. De fylls bara till hälften. När vattnet pumpas upp i lovart ökar rätande momentet med motsvarande 4-6 man på relingen.

Celeste Coupé skall inte kappseglas egentligen... men man vet ju aldrig! Ägaren har kappseglat hela livet på en bra nivå, senast med förra båten, en X-yacht, i Copa del Rey. Han har en bra besättning om det blir dags igen. Båten kommer att vara svår att slå, särskilt i lätt- och mellanvind.

BYGGE
Skrov och däck till Celeste Coupé är byggt på en kärna av Divinycell, med multiriktat glas och vinylester. Enkellaminat i kölfickan och andra högt belastade områden. Balkar och stringers kombinerade med inlaminerade skott och inredningsdetaljer ger en stum struktur. Kölfenan är gjord av solitt glas/vinylester ner till bulben av bly, som därmed ger en låg tyngdpunkt. Hjärtstock aluminium, JEFA.

Däcket är teakklätt, 8mm, med stående ådring och limmat med vacuum. Inredningen är uppbyggd till stor del med sandwichskott, klädda med fanér, hela träinredningen i obetsad hondurasmahogny och garnering mot skrovsidor i vitmålad ceder. Slät durk i teak, oljad med Timberex.

LAYOUT
Sittbrunnen är helt öppen akteröver men för långa havsseglingar, som till Korsika eller Mallorca, kan det vara trevligt att den är stängd. Så sittbrunnen på Celeste Coupé är både – och. När luckan fälls ner bildar den en ren förlängning av den teaklagda durken, och det finns en badstege som fälls ut ur en lucka i luckan. Räckena på pulpiten gör det enkelt att enkelt gå ombord från aktern.

Styrningen är ett JEFA-system med länkarm. Vitmålad aluminiumratt med dubbla rader av ekrar, klädd med älgskinn. På piedestalen finns alla elektriska kontroller i en rostfri inneslutning under kartplottern. All instrumentering från Raytheon.

Rorsman har två eldrivna Andersenvinschar till förfogande. Storskotet kommer fram ur sargen på båda sidor och nere i brunnen finns ingen skena, bara ett enkelblock mitt på durken. På längre bogar kan storskotet alltid ligga på lovartsvinschen och focken i lä. På så sätt kan all segling och manövrering kan skötas från rorsmansplatsen.

Ett system med avlastare och ytterligare två manuella Andersen används vid kappsegling, kortare slag eller när gennakern eller code zero är hissad. I däcket vid sidan om sittbrunnen finns en lucka på varje sida för alla tampar.

De generösa sofforna i sittbrunnen är i första hand tänkta för avkoppling, måltider och för att sova under stjärnhimlen när vädret tillåter.

Inredningen på Celeste Coupé är gjord för två personer. Förutom toalett och dusch om bb är hela utrymmet gjort utan skott och dörrar. På styrbords sida är pentry med många draglådor under bänkarna, elspis med glashäll, mikro och stor kyl med lucka uppifrån och dörr framifrån.

Salongen är inredd med en svängd L-soffa om bb och om sb ett öppet kontor med byrå, snurrstol och arbetsbord. För därom ett öppet halvskott med draperier som kan dras för om man så önskar. Det finns en större dubbelkoj om bb och en enkelkoj om sb, båda med specialbyggda resårmadrasser från Madrassfabriken. Längst föröver under flushdäcket är ett litet dressingroom med 3 garderober och speglar, i anslutning till sovavdelningen.

Båten är luftkonditionerad. Denna anläggning kan också användas för att ge värme.

INSTALLATIONER
Under lucka i durken i sittbrunnen ligger ett litet maskinrum med motor, 3,5 kW generator, dagtank för diesel, laddare och inverter, airconditionanläggning, bordgenomföringar, pumpar och filter och det speciella pumpsystemet för att skifta vatten upp i lovart.

Ballasttankarna ligger vid sidan, utanför skotten till maskinrummet och under bänkstuven. Akterut vid rorsmansplatsen en stuv om bb för livflotte och om sb för dusch och badgrejor.

På fördäck finns en stuv stor nog att gå ner i. Det finns ett Lewmar ankarspel med kapstan, ett rostfritt Bruceankare 15kg hänger i ankarpeket, 60m kätting ligger i en avskild kättingbox längst akterut i stuven.

UNDER SEGEL
Med all sin utrustning väger Celeste Coupé drygt 6 ton i lätt lastat tillstånd. Med tanke på det är det fascinerande att känna accelerationen i båten när det kommer en liten bris. Styrningen är exakt, som en jolle, men lite ovanligt är att hon är helt kursstabil. Släpper man ratten lovar hon upp mycket sakta.

Vi har ännu (mitten av oktober) inte haft tillfälle att provsegla båten i frisk vind eller höga vågor men från erfarenheten av tidigare större systerbåtar förväntar vi oss exceptionellt bra fart på kryss i öppen sjö, behagliga rörelser med mindre pitching än normalt, och en torr gång. Det skall bli mycket intressant att därtill få uppleva effekten av vattenballasten.

Manövreringen är enkel och förutsägbar. Motorn - en Volvo Penta på 40 hk med S-drev - upplevs som kraftfull och mycket tyst. Det krävs inget stort gaspådrag för att ge henne fart. Hon backar ut från bryggan med en precis kontroll, vänder på sin axel, och ute på fritt vatten gör hon 8½ knop för motor.
