Draft markings on the stern of the Cutty Sark, an example of the Imperial system of such markings. The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. [1] Draft varies according to the loaded condition of the ship.
Sun Odyssey 349 Shoal Draft This model has a shoal draft wing keel, giving a draft of 4.92 ft (1.50 m). It displaces 12,390 lb (5,620 kg) and carries 4,101 lb (1,860 kg) of cast iron ballast. [1] [4] [5] Sun Odyssey 349 Lifting Keel This model has a shoal draft wing keel, giving a draft of 8.33 ft (2.54 m) with the keel down and 4.08 ft (1.24 m ...
The liner's speed at the time was 24 knots (12 m/s) and the draft was 32 feet (9.8 m). The rock upon which the vessel grounded was an uncharted shoal later determined to be 34.5 feet (10.5 m), which should have given her room to spare, were it not for the "squat effect."
The boat has a draft of 2.08 ft (0.63 m) with the standard shoal draft keel fitted or 4.17 ft (1.27 m) with the deep "bluewater" keel. [1] [2] [4] The boat may be optionally fitted with a Japanese Yanmar 1 GM10 or Westerbeke 20B diesel inboard engine or a small outboard motor for docking and maneuvering. [1] [2]
The boat has a draft of 5.17 ft (1.58 m) with the standard iron-ballasted keel and 3.92 ft (1.19 m) with the optional longer shoal draft lead-ballasted keel. About 90 were built with the shoal draft keel. [1] [5] The boat was initially fitted with a Japanese Yanmar YSE diesel engine and later a Yanmar 1GM model. [1]
The hull has a spooned plumb stem, a vertical transom, a transom-hung rudder controlled by a tiller and a fixed fin, shoal-draft keel. [1] [3] The boat has a draft of 18 in (46 cm) with the standard keel and is normally fitted with a small outboard motor for docking and maneuvering. [1]
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material, and rises from the bed of a body of water close to the surface or above it, which poses a danger to navigation.
Catalina 320 Original model introduced in 1993. This version has a draft of 6.46 ft (1.97 m) with the standard keel and 4.25 ft (1.30 m) with the optional shoal draft wing keel.
