Deck General · Ship Construction — Panting & Pounding
'Pounding' (slamming) stresses are experienced primarily:
- AAt the stern in calm water
- BIn the forward bottom when the bow emerges and re-enters the sea in a heavy head sea✓ Correct
- COnly at anchor
- DIn the engine room
Explanation
Pounding/slamming occurs when the forefoot lifts clear in a seaway and slams back down, hammering the forward bottom plating—reinforced for this. Panting is the in-and-out plate flexing at the bow from cyclic water pressure; racking is transverse distortion from rolling.
