F1 boats are powered by a Mercury Marine [citation needed] V6 two stroke that burns 100LL Avgas at a rate of 120 liters (32 gallons) per hour, generating over 400 horsepower at 10,500 rpm. This engine can propel the boats to 100 km/h (62 mph) in less than two seconds and to a maximum speed of over 250 km/h (155 mph). [citation needed]
A Class 1 race-boat has twin inboard 1100hp engines and can reach speeds in excess of 257 km/h (160 mph). All boats are limited by a minimum weight of 4950 kg. The sport of powerboat racing has undergone unprecedented changes since the earliest recorded race in 1887 in Nice, France, organized by the Paris Sailing Club.
Offshore powerboat racing is a type of racing by ocean-going powerboats, typically point-to-point racing. In most of the world, offshore powerboat racing is led by the Union Internationale Motonautique (UIM) regulated Class 1 and Powerboat P1. [1] In the US, offshore powerboat racing is led by the APBA/UIM and consists of races hosted by ...
World No. 1 Scottie Scheffler capped off a historic year with triumph at the season-ending Tour Championship on Sunday, cruising to a four shot victory in Atlanta.
Hull speed or displacement speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel. As boat speed increases from rest, the wavelength of the bow wave increases, and usually its crest-to-trough dimension (height) increases as well. When hull speed is exceeded, a vessel in displacement mode ...
Barefoot skiing is water skiing behind a motorboat without the use of water skis, commonly referred to as "barefooting". Barefooting requires the skier to travel at higher speeds (30–45 mph/48–72 km/h) than conventional water skiing (20–35 miles per hour/32–56 km/h). The necessary speed required to keep the skier upright varies by the ...
A jetsprint hull is typically short - just 3.8 to 4.0 metres (12½ to 13 feet) long. The hull's vee is usually 23 to 25 degrees with several strakes on each side. A short hull is preferred, as a longer hull takes more distance to turn and usually must be turned at a slower speed. The strakes provide "traction' by stopping the boat from sliding ...
Records 1912–1976. The first manual time of 9.9 seconds was recorded for Bob Hayes in the final of the 100 metres at the 1964 Olympics. Hayes' official time of 10.0 seconds was determined by rounding down the electronic time of 10.06 to the nearest tenth of a second, giving the appearance of a manual time.
