progress, to take note of the measurement or tonnage rule which caused the change in the form of the yacht.
The yacht of the early part of the century was an apple-bowed craft of about three beams to length, ballasted with stone, gravel, or old iron. Competition was restricted to matches between two yachts, the bigger craft, other things being equal, usually winning. The first rule was derived from the mercantile marine, and had been in force since 1794. It was one in which length of keel and fore-rake, and the breadth at broadest place, were the only dimensions that were measured. It did not matter how high or how low the vessel was in the hold, half-breadth was taken to represent the depth, in calculating tonnage. The tendency of this rule was to make vessels high, narrow, and flat-sided, in order to get as large a carrier as possible with the smallest registered tonnage. This was called builder's tonnage, and was in vogue until 1854 in the mercantile marine. It was applied to yachts simply as a guide for building them or for their purchase and sale.

It struck Mr. Holland Ackers as being somewhat of an anomaly, so he proposed a table of time allowances between large and small yachts, the basis being the difference in
