Soft caps are described as forming the top of the keel and side blocks and have what thickness?

• A. 2-6 inches
• B. 1-2 inches
• C. 7-9 inches
• D. 0.5-1 inch

Answer: (A)

Soft caps provide a protective cushion on top of the keel and side blocks, spreading the hull’s load and shielding the hull from damage when the ship is supported in drydock or on blocks. The specified thickness of 2 to 6 inches reflects a balance between enough cushioning to prevent indentations and damage, and not raising the hull so high that alignment and clearance become problems. Thinner options wouldn’t absorb the load adequately, while thicker ones would unnecessarily increase height and could interfere with supports. Therefore, 2–6 inches is the standard thickness.
