Section 5 Longitudinals

501. Spacing

The standard spacing of bottom longitudinals is obtained from the following formula:

Ċ Ņ Ī Ã Ñ JJL (mm)

502. Scantlings

The section modulus of bottom longitudinals is not to be less than obtained from the following for- mula:

Ī 3

Ěᾎ Ņ Ķ Ċᾜᾨ (cm )

where:

ᾨ = Spacing of solid floors (m)

Ċ = Spacing of bottom longitudinals (m)

ᾜ = Vertical distance from the longitudinals to a point of ᾘ Ñ LǾLĪĴ Ã above the top of keel (m)
