• Drambuie's attempt on the Royal Marine's round-Britain record for power boats has provided Dumbarton-based Yachtech with its first venture into building HGV trailers.
Transporting the £1/2 million 14-metre Scarab Meteor with its 634kW-twin Cat-V8 diesels from its Scottish base to London called for a cradle platform trailer, 50mm below the 18 metre 'unescorted' limit.
The angled stepframe skeletal trailer has a cranked beam chassis, fitted with a railed-off area at the back to protect the boat's rear end in traffic.
Running gear comprises twin four-tonne solid beam axles with compensated multileaf springs and 8.25R15 single wheels. Twin Knott air brakes provide the stopping power via 406mm brake chambers.
Unladen, the trailer scales 1.7 tonnes. With its full quota of replacement boat parts stowed along the aluminium decking and in lockers over the neck, plus 'Challenger' on board, the trailer grosses almost 10 tonnes.
