MILFORD Marina will play host to international powerboat championship contenders Daisy and Sam Coleman as part of celebrations to mark the marina’s 25th anniversary.

The siblings are currently making waves in the Powerboat P1 Superstock Championship series, which takes place in around Florida in the US and in various parts of the UK.

Neither come from a boating background, and Daisy, who co-pilots for the races, had never stepped foot inside a powerboat until four years ago when she was discharged from the Royal Artillery on medical grounds.

They are now winning trophies on a world platform, their most recent success being at the English Grand Prix of the Sea, where they finished second overall and extended their championship lead to 25 points.

Their next event will be on August 28 and 29 at the Welsh Grand Prix of the Sea at Cardiff Bay.

Daisy said: “We’re delighted to be invited to this event to celebrate Milford Marina’s 25th anniversary.

"There’s no better way to explore the UK’s largest coastal national park than by boat and Milford Marina has provided us with a fantastic base for launching and testing our race boat. We look forward to visiting this fantastic marine destination in the future.”

The Port of Milford Haven is also running a '25 reasons to visit Milford Marina' campaign, highlighting the range of businesses and attraction on offer to both visitors and locals.

The 28-foot long powerboat will be on Mackerel Quay on Saturday, July 16, from 2pm until 3.30pm if visitors would like to take a look at the vessel and have a chat to the team.
