SAY Yes to Outstanding Fun with SAY Carbon Yachts
SAY Carbon Yachts are handbuilt German performance speedboats made entirely from carbon fibre, produced near Lake Constance by Sven Ackermann's company founded in 2006. Their flagship model, the SAY29 Runabout Carbon, is one of the most distinctive performance powerboats available: a 29 ft all-carbon hull that weighs just 1,380 kg, reaches 100 km/h on the water, and arrives in colours that have nothing to do with traditional boating white and blue.
Who Is SAY Carbon Yachts?
SAY was founded in 2006 by naval architect Sven Ackermann near Lake Constance, the body of water that borders Germany, Austria, and Switzerland. The company was built around a single conviction: that performance powerboats did not need to look like every other boat on the water. By using all-carbon fibre construction with epoxy sandwich layup, SAY achieves hull weights that competitors using glass fibre or composite construction cannot match. Every boat is handmade in Germany, and the production runs are deliberately limited, a detail embedded in the model naming: the 29 in SAY29 refers both to the boat's length and the total number of units built.

The SAY29 Runabout Carbon: Specifications
The SAY29 is 29 ft (8.85 m) long, with a beam of 9.1 ft (2.78 m) and a bare hull weight of approximately 400 kg. Fully fitted, the complete boat weighs 1,380 kg. Three engine configurations are available: a V8 6.2L Mercruiser producing 350 hp, a V8 4.2L Mercury Diesel at 370 hp, and a V8 6.2L Illmor at 500 hp. All three push the SAY29 to a top speed of 100 km/h, a figure the lightweight carbon hull makes possible at engine sizes that would produce only moderate speeds in a conventional fibreglass boat.
Seating is for six passengers. The suspension seats are made by Ullman Daytona, a company that specialises in offshore racing and military vessel seating, built specifically to absorb impact at speed. The interior finish is consistent with the exterior build quality: no visible shortcuts, no cheap switchgear.

Bold Colours in a White Boat World
Standard powerboat aesthetics lean heavily on white hulls, teak accents, and navy blue canvas. SAY29 arrives in neon orange and neon green, a visual statement that is as deliberate as the engineering beneath it. The colour strategy exists to make the boat identifiable at distance on the water and to signal that this is not a conventional manufacturer following category norms. It works: the SAY29 is immediately recognisable in any marina.

The SAY29E: World Electric Speed Record
SAY extended the platform with the SAY29E, a fully electric version of the same carbon hull. The 29E is fitted with a 120 kWh battery and a 360 kW electric motor producing 483 hp. In 2019, the SAY29E set the world speed record for electric production boats at 51.3 knots (95 km/h) over a 463-metre measured course, becoming the fastest electric production boat on water.
