When boats don’t have enough head room it is standard practice to raise the freeboard or extend the overall length. However when you have bought a record breaking trimaran it is perhaps a little expensive to do either.
Simple solution on Guo Chuan’s tri – the former IDEC – just stick it on deck – no one will see you mid ocean anyway!
They currently sit in San Francisco waiting to set off shortly to set a reference cross Pacific time. We have difficulty in calling it a record when no one else has done it before. A bit like the North East Passage “Record” they set not so long ago. Not so sure their head will do too much for efficient windage although an interesting design solution to an age old problem on racing yachts.
