USCG has issued a policy letter providing post-installation testing guidance following replacement of on-load release mechanisms (release hooks) for lifeboats and rescue boats on all vessels subject to SOLAS Chapter III.
USCG has determined that a demonstration of the ‘5-knot test’ may be unnecessary in some circumstances and infeasible in others. This guidance is intended to assist Officers in Charge, Marine Inspection (OCMI) in making this determination and provides for the acceptance of alternative tests and/ or waiving the test in certain scenarios.
OCMI may apply the guidance in determining whether or not the 5-knot test must be performed as part of the post-installation testing. Further details may be found by reading the policy letter below:
