with the boat ''Miss America VII''. The current world speed record for wooden boats of 200.943 km/h was set in 1932 with the boat ''Miss America X''. The goal for S-1 Sverige is 185 km/h (100 knots), and after being built the boat soon managed to reach 120 km/h without a compressor. The boat has since sunk, been raised and rebuilt two times. During the last rebuild it was fitted with a

fighter plane. Fitted with compressors, the two engines yield a combined power output of about 1800 kW (2500 hp) and a torque of 2400 Nm. The boat has a fixed-angle propeller shaft angled about 5 to 6 degrees, as in the original drawing. With the current setup, top speed is claimed to lie around 140 to 150 km/h.

Accidents

May 2012, the boat partially sank outside Sandhamn in Sweden after the propeller hit a hard object during an early test run, which tore off the propeller shaft leaving an opening in the hull. This resulted in the boat taking in large amounts of water upon slowing down. The boat ended up partially submerged, with only the front of the boat sticking up from the water. No persons were injured.Ops! Sverige S1 sjönk vid Sandhamn - DagensBåtliv.se

The boat made a full rotation, and the crew were bruised heavily by the boat interior before being thrown out of the boat. Two out of the three-man crew were sent to hospital, but all escaped without serious injuries. The boat sank to a depth of about 10 meters, and was later raisedTV: Så här otäck var kraschen med SVERIGE S1 - Livetombord.se
