 huge when its inherent scientific possibilities are considered. Since Nat Herreshoff made practicable the crude fin-keel of former designers, no such interesting phase of marine architecture has been evolved.

As a matter of historical fact, it remained for Mr. Duggan to revive interest in the type, and this he did most effectually by the production of Dominion. The craft has given rise to much discussion among yachtsmen and in the press, both at home and abroad. The point of sailing in which Dominion excels is close-hauled on a wind or with the wind abeam. It is then that she sails on her lee hull only, the weather hull serving the same purpose as the ballast of a "sand bagger," enabling her to carry a good press of sail. This is shown by Figure II., which portrays her when heeled. With the wind dead aft and both hulls immersed, Dominion in the races at Dorval was slightly slower than her rival, her paramount advantage being gained when sailing with one hull immersed.

Dominion's dimensions are: Length over all, 35 feet 10 inches; on load water-line, 17 feet 6 inches; extreme beam, 7 feet 7-1/2 inches; beam, load water-line one bilge, 2 feet 5-1/2 inches; draught of hull, 10 inches; draught with board, 6 feet; freeboard, 1 foot; displacement, 1,750 lbs.; area midship section, total 2.88 square feet; sail area, 500 square feet.
