Inboard racing classes consist of both Runabout and Hydroplane classes. You can tell a boat’s class by the letter(s) next to the boat number. All inboard drivers are required to wear a racing helmet and lifejacket as well as other protective gear such as fire-resistant Nomex and cut-resistant Kevlar. Drivers who race inboards with an enclosed cockpit (capsule) are required to pass APBA capsule training and certification every two years. Nobody plans to flip, but it does happen from time to time…and when it does happen, the training pays off.
Inboard Runabouts, or flatbottoms, come in both the open cockpit and capsule variety. Flatbottoms are known for their long lean shape, which allows the boat to slice through water as they move at speeds of 100+ MPH. Got a friend? Some runabouts run with two racers on board – a driver and a mechanic
Hydroplanes glide over the water on a cushion of air, with only the propeller and sponsons on each side touching the water while air rushes under the hull, giving the boat the “lift” it needs to skim across the water. These bad boys are fast, with some classes running at speeds in excess of 150mph - Inboard hydroplane classes range from 1 liters (T-Boats) to the 1500hp supercharged Big Block Chevrolet V8 Grand Prix (GP). All inboard hydros utilize a capsule safety cell as well as racing lap and shoulder belts. Controls are similar to those of an automobile – steering wheel, accelerator pedal, rear view mirrors – but no brakes!
WATCH OUT for roostertails! If an inboard hydro is in front of you, chances are you’re about to get blasted with a wall of water from the giant roostertail of the boat in front of you. Racing into a turn favors the leader, with those behind having to deal with roostertail fallout!
