A record-breaking powerboat is set to appear at the Southampton International Boat Show.

The 22-metre Thunder Child II, which holds six world records, will be showcased at the event in September.

The boat, which has a top speed of 54 knots, is owned and piloted by Nick Ogden, the founder of Worldpay.

The 54 Knots crew use their record attempts to collect data for developing seawater-based fuel cell systems.

The team's mission is to generate enough power to charge the electric engine on their tender using just saltwater-based fuel cells.

Nick said: "We are excited to share the Thunder Child II in all her glory in Southampton International Boat Show’s purpose-built marina this September.

"The whole 54 Knots crew, supported by Performance Marine Group, is preparing to share our life at sea with visitors, show them onboard, and give them real insight into the world of competitive global endurance racing."
