🔍 Key Concepts

• Maintenance and inspection intervals for survival craft under SOLAS/46 CFR • Difference between inspection (visual/operational checks) and thorough overhaul (strip, clean, and recondition) • Manufacturer’s recommendations versus regulatory minimums for periodic maintenance

💭 Think About

• Think about how often major, labor‑intensive work like stripping and overhauling survival craft would reasonably be required compared with simple monthly inspections. • Compare the answer choices to other known time intervals: monthly drills, annual inspections, and 5‑year tests. Where would a full overhaul logically fit among these? • Ask yourself which interval balances safety (not too long) and practicality/cost (not too frequent) for completely overhauling all lifeboats, rescue boats, and rigid liferafts.

✅ Before You Answer

• Confirm in your references how often thorough overhauls (not just inspections) of lifeboats and rigid liferafts are required. • Verify that you are focusing on the interval for stripped, cleaned, and thoroughly overhauled, not routine checks or servicing. • Eliminate any option that seems more appropriate for routine inspection rather than a full overhaul of all survival craft.
