The BOC for vessels is measured as follows: For a catamaran: the perpendicular distance from the centerline of one hull to the centerline of the other hull, measured at deck level. For a trimaran: the perpendicular distance between the centerline of the main hull and the centerline of either ama, measured at deck level. This term in typically ...
The camber is a measure of lateral main deck curvature in naval architecture. The curve is applied to a deck transversely, measured as the height of deck at centreline above the height of deck at side. The practice of adding camber to a ship's deck originated in the era of small sailing ships.
The bore and the stroke was 88.9 mm × 88.9 mm (3.50 in × 3.50 in), making it a square engine. The block deck height was extended and longer conrods were fitted 158.75 mm (6.250 in) between centres. A Bendix Stromberg two-barrel carburettor was used in place of SU carburettors. [11]
In sailing and boating, a vessel's freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. [1] In commercial vessels, the latter criterion measured relative to the ship's load line, regardless of deck arrangements, is the mandated and regulated meaning. [2]
Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often reported. This is especially useful for smaller sailing vessels, as their LOA can be significantly different from their LOD.
The RB engines, produced from 1959 to 1979, are raised-block (taller) versions of the B engines. All RB engines have a 3 + 3 ⁄ 4 in (95.3 mm) stroke, with the bore being the defining factor in engine size. All RB wedge engines share a deck height of 10.725 in (272.4 mm), and were fitted with 6.768 in (171.9 mm) long connecting rods, resulting ...
The first engine in the 335 series was introduced in late 1969 as the 351C. The 400 cu in appeared in the third quarter of 1970, which raised deck height from 9.206 in (234 mm) and tall deck 10.297 in (262 mm) to accommodate a longer stroke, and used larger main bearings for additional strength.
