question on term
The term "Half Tonner" harkens back to the old days of the IOR racing rules. It was known as "Level Racing" in that boats that were measured to the rules formula of the day, and the result was a particular handicap, they would all race togther, first boat accross the line wins. No handicap involved. The classes were Two Ton, One Ton, 3/4 Ton, Half Ton, Quarter Ton.
In size ranges, Two Ton boats were approximately 42 feet, One Ton about 37'', 3/4 Ton about 32 feet, Half Ton about 28 feet, and Quarter Ton about 24 feet.
The actual term "Ton" is a reference to an old, I think French, term having to do with the drayage capacity of a particular sailing vessel. Commercial boats were rated by their "Ton" regarding their waterline length and their sail area and displacement.
