Much to my chagrin Mrs. Nobber, you are close to being eliminated from the competition as you have made the assumption that the boat is big. It isn't as it measures only 23'.
If it is of any help at all, the owner at the time that the boat first raced in the mid 60's might have preferred a shandy (or a magnum of champagne) but his Lordship that raced at the time with him would not have heard of it. He would have rather disappeared. Then again, it might have been a good formula for an escape into oblivion.
