Her beam was 26 ft. 6 in., 8 ft. 3 in. depth of hold, 5 ft. 2 in., draught of water at stern, and 8 in. forward. She had two centreboards, a small one near the stern to aid in steering, and the large board 24 ft. long in the usual position; this main board was of iron and lead, weighing over seven tons. When first launched 'Maria's' centreboard was not pivoted, but worked in a vertical line, both ends being dropped to the same depth. The great weight of this board was partly balanced by two large spiral springs, one at either end, which were extended when the board was lowered. Length of mast 92 ft., 2 ft. 8 in. in diameter at deck, and 1 ft. 11 in. at hounds; it was a hollow spar, being bored out, for the first 20 ft. having a hole 12 in. in diameter; for the next 20 ft. 10 in., and above that the bore was 7 in. Her main boom was 95 ft. long, 2 ft. 7 in. in diameter and 2 ft. 4 in. at the slings; it was built up with staves like a barrel, inside it was a system of truss-work with long tension-rods reaching nearly to the ends. Length of main gaff 61 ft., with a diameter of 2 ft. 2 in. Her bowsprit had an extreme length of 38 ft., with a diameter of 2 ft.; it entered the hull of the yacht below deck, leaving the deck space above all free and clear; there was also a jibboom which materially lengthened the bowsprit, so that the point where the jib-stay was attached was 70 ft. from the mast. Area of mainsail, 5,790 sq. ft.; the cloths of this were placed parallel to the boom, the bighting running fore and aft instead of vertically as usual. It was thought by the Commodore and his brothers Robert and Edward, who were equally interested with him in the ownership of the yacht, that a sail thus constructed offered less opposition to the passage of wind than a sail made in the usual style; but the plan was open to objections, so that it never became popular. Her jib presented 2,100 ft. of surface, leach 69 ft.; its foot, 70 ft.; foot of mainsail, 94 ft.; hoist, 66 ft.; head, 60 ft.; and leach, 110 ft. 'Maria' had a working topsail, but it was rarely set.

Stevens, of Hoboken, U.S.A._)] Commodore Stevens with his famous craft took part in many races and matches during the first six years of 'Maria's' life; she usually beat all her competitors, the few failures she suffered being attributable to the failure of one or other of some new devices in her rigging or fittings; for her owners were for ever trying something new in way of experiment.
