In this method of measuring bowsprit including jibboom and out-board part of spanker boom if any have both no effect on the ship's length. The longest length for comparing ships, the total "overall" length (LOA) based on sparred length, should be given if known.
When determining a ship's bowsprit length, including jibboom and spanker boom components, these elements do not affect the ship's total length. To compare ships accurately, the longest measurement available should be reported as the "overall" length (LOA), calculated from sparred length, if feasible.
