If you like your tenders sleek and swift, the Spire Yacht 46 catamaran from Spire Boat and Henry Ward Design will grab your attention and not let go until you release the throttle.
Those of you who’ve attended the Monaco Yacht Show in recent years may remember seeing Spire Boat exhibit its speedboats/tenders in the tenders area. The company’s principals got their start in professional powerboat racing and decided to expand into the pleasureboat market, establishing Spire Boat in 2006. (On an interesting side note, Spire Boat takes its name from an Old English word, spīr, which means propeller.) As for Henry Ward, he’s the designer behind the Cockwells tender for the Vitruvius megayacht Grace E and who partnered with BMT Nigel Gee for the famed Recreational Island concept design.
The Spire Yacht 46, measuring 46 feet (14 meters) and with a beam of 12’6” (3.85 meters), should take eight months to build. Spire Boat plans to employ carbon fiber and composite construction for the catamaran. This, plus a pair of 662-hp to 1,350-hp Mercury Racing stern drives, should permit the Spire Yacht 46 to see cruising speeds around 65 knots and a blistering top end of 90 knots. That means you and up to five or six other passengers, depending on the seating arrangement, will have smiles literally plastered to your faces. What’s more, tests conducted by Spire Boat’s engineering team show that the Spire Yacht 46’s fuel consumption at cruise speed should be about 92½ gallons per hour (350 liters per hour), less than you might expect.
More than you might expect, however, are the catamaran’s accommodations. Three staterooms, one being an owner’s stateroom with an en suite head, will be aboard the Spire Yacht 46. A shared head serves the other staterooms and can double as a day head. A small galley will take care of lunches and snacks while you’re out on the water. Another nice feature: The two helm seats can pivot to face dining tables and the rest of your guests. Those tables are further removable.
Upping the ante on luxury, Spire Boat and Henry Ward Design are offering an optional seawater hot tub in the foredeck sunbathing area, adorned with 240 carats of diamonds. For those of you with simpler tastes, the Spire Yacht 46 comes standard with a diving board extending from the port side here, and can be ordered with sunpads to cover the engine hatch. Either way, the tender has a gullwing door-like opening in the windshield to access the foredeck.
Spire Boat will be at the upcoming Monaco Yacht Show and is taking appointments to discuss the Spire Yacht 46. Contact the company or fill out our contact form, and we’ll put you directly in touch with the appropriate parties at Spire Boat and Henry Ward Design.

Looks good but I can see loads of problems
1. If she is as fast as Nor-tec or similar brands then TV’s etc the way they are mounted will not last long with the constant banging hitting the waves. All items inside will have to be built especially for the vessel mucho Dollars
2. whirl pool? I take a guess you will fill that with sea water once finding a spot to party with the ladies? I do not think a whirl pool would hold the water over waves and the weight distribution of heavy water moving around with also the weight over the bow. There will be trouble ahead if she nose dives into a nice wave, I can hear the sound of smashing carbon now. If you do fill once parked I wonder which drunken fool will forget to release all the water before setting off back to port.
3. I can not see a wealthy guy setting all this up unless he takes a captain then its not a personal toy.
So to conclude nice drawings of something that will not work maybe all these designers should pay me to sort out their designs and get their heads out Disneyland.

Given Spire Boat’s background in offshore racing and pleasureboats, this project should have the customary CFD studies already done; don’t mistake either Spire or Henry Ward Design for companies that are fly by night or wannabes.

Dear Diane, thanks for your clever comment, you tell the truth.

Dear Keith Pearce, you will be the only one to take a spa (whirl pool) during a storm and also the only one to sail with water inside because with the security nobody can sail with full whirl pool. Please stay grounded and try to put interesting comments. For your information, nothing is more stable than a catamaran hull, except when no boat is on the sea.

Concept is great and we would love to see the calcs on this one. We have done some interesting work on larger vessels and something like this would be a real challenge if a full working / heating system is involved. Dumping of water prior to setting off could be interlinked with the vessels start up system, not allowing the engines to engage until the ballast of water has been offloaded.

Thanks Peter Rigiani for your clever comment. Pearce should read you and inspire him from you before talk about he doesn’t know. C.SADOUX, Founder of SPIRE YACHT & SPIRE BOAT.
