Light at the end of the tunnel

Yesterday saw Team Britannia boss Alan Priddy talking technical stuff at ABC Marine on Hayling Island. They always knew that the mooring posts and cleats for the boat would have to be immensely strong, but just as importantly, they had to be sited in the correct positions.

Whilst crunching the numbers on this, they also ascertained the kind of stresses on the deck likely to be encountered in the extreme event of what is known in the boating world as “stuffing” – where the boat ploughs into a wave at speed. One hopes this isn’t too often, but it happens! On the round the world powerboat Spirit of Cardiff, the most impressive stuffs resulted in broken windscreens! While Excalibur has already been designed to withstand everything that can be imagined, they decided to add some extra upright bars between the keel and deck to provide additional bracing in the event of a full stuff, which could see as much as 100 tons of water on top.

They’ve decided too that the cabin floor will be made from 3/4 inch plywood, with substantial aluminium bracing underneath. With all six 6,000 litre fuel tanks and all the bulkheads in place, they’ve started attaching the deck panels, and the wheelhouse – already assembled – will soon be craned into place and welded on. If that isn’t exciting enough, I can also report that the engines are booked up to be installed in the first week of June. We’ve been down an extremely long tunnel, but the light at the end is now getting very close…
