__NOTOC__ Length overall, often abbreviated as (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking of the ship. It is the most commonly used way of expressing the size of a boat, and is also used for calculating the cost of a marina berth〔 (【引用サイトリンク】title=Boat Moorage )〕 (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone.〔(【引用サイトリンク】title=Definitions of: Boat, Yacht, Small Craft, and Related Terms )〕 For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA.〔 〕 However, other sources may include bowsprits in LOA.〔(【引用サイトリンク】title=The Dictionary of English Nautical Language )〕 Confusingly, LOA has different meanings.〔 〕〔(【引用サイトリンク】title=Glossary )〕 "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. ==LOD== 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.〔(【引用サイトリンク】title=The Dictionary of English Nautical Language )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Length overall」の詳細全文を読む スポンサード リンク
