Breaking in my 2.8L M20 on a DTS dyno. The smoke is from some accidental motor oil spill and some ran down the manifold. 15mins into the run it burned off. Made 177ft/lb @ 2500rpm with no tune during break in.

► Full test in Multihulls World N°193. ► The Gunboat 72 had its first official presentation at Cannes, and was impossible to miss, with its mast towering over 100 feet (30 meters) above the carpeted pontoons! Slightly longer and beamier than the Gunboat 68 (a model approaching the end of its career), the new catamaran also boasts a larger nacelle and, above all, a vast flybridge - a first! The aim is to introduce a comfortable, fast and luxurious multiyacht into the Gunboat family. Obviously, the 72 remains a high-performance catamaran, capable of sailing at wind speed from 8 knots. Compared to the speedy 68, it weighs over 10 tons, despite extreme care in the choice of materials and build quality... but the sail plan gives the impression of being more powerful than that of the Gunboat 68 Racing – 3,100 square feet (288 m²) upwind versus 2,712 sq ft (252 m²), and 4,844 sq ft (450 m²) downwind versus 4,682 sq ft (435 m²). Note that accommodation layouts are designed according to the owner’s wishes. ► Technical specifications: Builder: Gunboat Length: 72’2” (22 m) Waterline length: 72’2” (22 m) Beam: 30’10” (9.4 m) Draft: 5’7”/12’6” (1.7/3.8 m) Air draft: 106’2” (32.37 m) Light displacement: 62,600 lbs (28.4 t) Loaded displacement: 71,650 lbs (32.5 t) Mainsail area: 1,830 sq ft (170 m²) Solent: 1,270 sq ft (118 m²) A3 Spinnaker: 3,014 sq ft (280 m²) Fuel: 343 US gal (1,300 l) Water: 222 US gal (840 l) ► Become a FREE SUBSCRIBER to Multihulls World's YouTube page now - https://www.youtube.com/c/MultihullsWorld ► Log on to our website to discover over 500 multihulls tests!

► The 3D images we’d received had given us a good idea that the Tortue 147 wasn’t really going to look like a standard multihull... In the end, we were in for quite a surprise at La Grande-Motte! The catamaran on display, an ode to slow living, boasts a truly unique design and layout, with a nacelle reminiscent of a turtle shell, large stained-glass portholes, a suspended chart table seat, and a cabin layout reminiscent of a small mountain chalet. The same surprising atmosphere reigns at the after end of the boat, where a modest suspended balcony serves as a cockpit. We’re obviously impressed by the diamond-shaped windows integrated into the floor of the nacelle, and we are hardly surprised by the presence of a beautiful plant, whose pot was designed during the construction process. The build was undertaken in Tunisia using semi-thick aluminum for optimal impact resistance. The hull has two specific features: a bulbous bow is grafted onto each side to dampen pitching, and the stern is particularly sleek. Here again, the architects’ aim was to provide the most stable platform possible, including longitudinally. Two 1,200-liter (317-gallon) ballast tanks are also provided aft. Long keels and rudder skegs allow you to take the ground. The conventional internal combustion engine has been supplemented by an electric propulsion system capable of propelling the Tortue over a distance of 12 nautical miles and providing efficient hydrogeneration when the catamaran is making way under sail. ► TECHNICAL SPECIFICATIONS: Builder: Cataruga Material: 8 to 10 mm aluminum Length: 48’3” (14.7 m) Beam: 25’9” (7.85 m) Draft: 4’9” (1.45 m) Displacement: 37,500 lbs (17 t) Sail area: 1,076/1,507 sq ft (100/140 m²) Motors: 2 x 57 HP and 2 x 10 kW All-electric range: 2 hours at 6 knots ► Become a FREE SUBSCRIBER to Multihulls World's YouTube page now - https://www.youtube.com/c/MultihullsWorld ► Log on to our website to discover over 600 multihulls tests!
