SOLAS Ring Lifebuoy

Verify battery replacement date, inspect expiration label per LSA Code para 1.2.3, confirm SOLAS/MED/USCG certification current. Lithium models should show 5-year maintenance-free certification.

Check danbuoy/horseshoe for physical damage, corrosion on CO2 cylinders, activation pins secured. Verify cartridge weight (typically 33g) matches specification. Test inflation (per manufacturer service intervals, usually 3 years).

Inspect floating lines for UV damage, abrasion, mildew. Verify line length matches specifications (test by measurement). Check all attachment points (carabiners, clips, D-rings) for corrosion, cracks. Ensure stainless steel (316) hardware used. Load test clips per ISO 15085 (minimum 375kg for boarding ladders).

Verify bracket securely fastened to pulpit/rail (rail distance 300-310mm typical). Test quick-release deployment manually (should separate without binding). Inspect bracket for corrosion, bent fasteners. Confirm safety pin or lanyard present and functional. After practice/test deployment, full re-certification required.

Verify battery manufacture date (7-year max life for lithium models). Confirm activation method (water-activated vs manual). For active units: test transmission range (5nm typical) with portable AIS receiver if available. Check waterproof seal integrity and GPS module responsiveness. Certificate of type approval must be current.
