Purposefully named trimaran yacht tTNT 34 after Trinitrotoluene, from which dynamite comes the company says. “This will be a new “exploding” and exciting trimaran that can be sailed by experienced sailors yet still be friendly for family use.”

A new ( subject to patent ) folding system gives an afloat beam 8.5 meters or 28 feet, yet closes to 2.99 m for towing on European roads.

The company claims the craft has a beam wider than any other similar sized production trimaran, allowing for an additional 20 % sail area.

This, the company says is where TNT 34 yacht will excel whether in fast cruising or racing. Simply put, “extra beam means extra sails and that means more speed.”

Technical Specifications of the Bond trimaran yacht TNT 34:

• Length 10.4 m (34 ’)

• WL 10.0 m (33 ‘)

• Unfolded beam 8.5 m ( 27.5 ‘)

• Beam folded -marina mode -3.9 m (12.8 ‘)

• Beam folded -trailer mode -2.99 m (9.8 ‘

• Disp. 1.89 T (4160 lbs) ready to sail, custom trailer galvanized 0.53 T(1160 lbs)

• Mast 15.1 m (made in France ) =50 ‘, see rigging design

• Sail Area: Main 55 m2 (591 sf) jib 26 m2 (215 sf)

• Power O/B 15-25 hp to push up to 9-11 knots

• Bottom -flat to encourage early planning,

• Floats at 1:22 ratio. Lots of buoyancy forward to prevent pitchpole

• Plumb Bow on the main hull and axe bows on floats

• Dual steering station (optional) for power, like on MC 30 and tiller under sail

• Large open cockpit

The TNT 34 yacht is made to plane in 8 knots or higher yacht speed due to a very flat transom and hull in general. The weight of 1890 kg or 4160 lbs should allow it to ”rise“ very quickly even in 10 knots of wind.

Optional Foils, should help this effect in stronger winds and also provide additional stability.

Much of the interior finish is drawn from the companies existing range of Motorcats.

Many elements that will come from tooling of the MC 29 and 30. Bond Yachts custom made “suede” liner will give a nice touch and softness to the future super yacht TNT 34. The liner is padded and almost as light as fairing and paint on other yachts. TNT 34 yacht will have a very voluminous interior and headroom of 1.95m (6’3“).

The withdrawing and folding floats are controlled by a novel approach developed by J. Kostanski in 2009 and subject to a patent. The idea was to combine two movements into firstly sliding and then pivoting as the beams are drawn in through a 60 cm (2ft) long sleeve. The arms have buoyancy and are supported by water thus making folding possible and easy.

On the trailer the floats are tacked away under the main hull without any disassembly.

The solid sleeve through which the arm is withdrawn. also acts as a long holder once bolted to the deck (similar bolting takes place on the Farrier system). Once the beam is locked in the sleeve the float is fixed via a cantilever to the main hull. To reduce forces two S/S wire struts will be provided for each float.

Ease of movement is assisted byTeflon strips inside the sleeve and SS strips on the beams. The beams require precise machining to avoid jamming and special aluminum tooling will be employed to assure straight lines and smooth sliding through the sleeves. The folding in will be also quick and effortless due to using the winch on the deck.
