Moving the world's tallest freestanding composite masts through some of the tightest channels in Portsmouth Harbour was always going to be a challenge.

However, with the expert help of pilots from Portsmouth International Port the 'oversized' load safely started its journey to Keil in Germany.

Manufactured by Magma Structures in Portchester, the masts are destined for a super yacht.  The masts have taken over 70 people, three years to develop, test, design and build. Working with heavy lift specialists Mammoet, the team from Portsmouth International Port spent weeks carefully planning the move, one of the most unusual and memorable ever undertaken in the harbour.

Lead pilot for the manoeuvre, Nick Hardesty, explained, “The move was particularly challenging as the barge used to carry the 100 metre masts was 69 metres long and 16 metres wide.  In certain sections the Portchester channel is only 20 metres wide, with yachts moored either side, so it required particular care and attention.”

Harbour Master Rupert Taylor said, “This move demonstrated a good example of working with multiple organisations within the area, carefully planning the move to minimise disruption to other harbour users, whilst carrying out the move safely.”
