SHAMROCK III : DATA TABLE & LINES

Category: SHAMROCK III

Shamrock III in dry dock at Erie Basin, Aug. 17, 1903For the new boat Sir Thomas turned back to William Fife, the designer of the first Shamrock. The boat was built under lock and key, and until she was launched nothing was known of the kind of craft Fife would turn out after his experience here in the race of 1899.
Shamrock III was launched early in the season, on March 17th 1903, day of Saint Patrick, under the most successful conditions.

(Video : Full record for 'LAUNCH AT DENNY'S : "SHAMROCK III" ') The underbody of the Shamrock III is painted with a white anti-fouling composition. Launch of ‘Shamrock III’, 1903 by Scottish Maritime MuseumHer topsides are white and she has broad bands of green along the water line and rail. Her hull, frames and plates are all of nickel steel, specialy made. The deck is of aluminium plates covered with wood fibre which gives a safe foothold.

00978SThe workmanship of the yacht is superb in every details. Neither dent, rivet, nor joint is visible under the polish of her paint.

Shamrock III was a beautifully modeled boat in spite of some extreme features, such as excessively long ends, low freeboard, etc. She was of the semi-fin type, though not as extreme in this respect as Shamrock II, and throughout Fife had kept as close as he could, with due regard to modern practice, to some of the older principles of the regular cutter type. Shamrock III, was much nearer the proper balance between moderate form and dimensions and economical driving power, than was the American boat, as we shall see when we study the latter's dimensions. She was not as big or as powerful a boat as Shamrock II., yet she was sweeter and abler in every way.

In Shamrock III, Fife had swung back toward the narrow cutter. She was the narrowest boat since the Valkyrie II. of 1893, being only some eight inches wider than the latter boat, though she was seventeen feet longer over all. She was built of nickel steel, which was a very strong alloy, and this was coated with white* enamel, giving a very smooth surface. Her dimensions, as far as they are known, were: Length over all 134 feet 4 inches, water line 89 feet 10 inches, beam 23 feet, and draft 19 feet, while her sail area was 14,154 square feet. She was also the first English challenger of cutter rig to adopt the American type of steering gear, being steered by a wheel instead of by a long tiller, as all the other cutters had been.
