Heartline Roll / Barrel Roll

First Passengers Ride Sik

A heartline roll, also referred to as a barrel roll is a manoeuvre commonly used in roller coasters and other thrill rides. During the Heartline Roll, the rider’s body moves in an essentially straight line, while rotating around the heartline.

A Thrilling Manoeuvre

The heartline roll is an exciting manoeuvre that is sure to thrill any roller coaster enthusiast. It was first introduced in 1985 on the Ultra Twister a Pipeline coaster at Tokyo Dome City. Since then, many roller coasters have been built featuring heartline rolls, including the popular Nemesis at Alton Towers Resort and ICON at Blackpool Pleasure Beach.

Sik at Flamingo Land

Sik at Flamingo Land Resort features a similar layout to Colossus at Thorpe Park in Surrey which also has 10 inversions, and a quadruple heartline roll.

The video below featuring Sik at Flamingo Land Resort shows how impressive the rides quadruple heartline roll looks to anyone watching the ride.

Why is it Called a Heartline Roll?

The heartline roll gets its name from the fact that the rider’s heart remains in the same position throughout the entire manoeuvre. This is because the rider’s body rotates around a fixed point that is located at the same height as the rider’s heart. As a result, the rider experiences a feeling of weightlessness as they rotate, similar to the feeling of being in zero gravity.

A Challenging Manoeuvre

The heartline roll is a challenging manoeuvre for roller coaster designers to execute, as it requires precise calculations of speed, force, and trajectory. The roller coaster track must be carefully designed to create the necessary momentum and force while keeping the rider safe and secure throughout the ride.

Maverick at Cedar Point

Once a roller coaster finishes construction it needs to undergo a series of tests before it can be opened to the general public. Cedar Point in Texas USA is home to some of the biggest and best roller coasters in the world including the former ‘Top Thrill Dragster’. In 2007 the American Theme Park added a new roller coaster named Maverick which featured a heartline roll. When the ride was tested with the heartline roll the results indicated that acceptable G force was exceeded so the element had to be removed and replaced with the s curve before the ride opened to the general public. This gives an indication of how hard it is to get the engineering of this ride element right.

With its pink and yellow paintwork, Rage can be seen from miles around, acting as a beacon pointing the way to Adventure Island. The entrance to the ride slices between the 90-degree lift hill and the beyond vertical drop. The ride was a major addition for Adventure Island when it was installed in 2007, at the time punching way above its weight. Rage is a very similar ride to Speed at Oakwood and Saw The Ride at Thorpe Park.

Speed is the tallest, fastest and steepest roller coaster in Wales. The ride is the UK’s original beyond-vertical-drop rollercoaster, and it’s definitely not for the faint-hearted. The thrilling roller coaster features a 90-degree vertical chain lift hill and a 97-degree beyond vertical first drop.


The heartline roll is a popular manoeuvre among roller coaster enthusiasts, as it combines the thrill of high speed with the excitement of a complete 360-degree rotation. Many riders describe the feeling of weightlessness and disorientation as the coaster rotates as one of the most exhilarating experiences of their lives.
