When sourcing a free fall lifeboat, the most critical factor is SOLAS (Safety of Life at Sea) compliance. You must verify the launching height capability, ensuring it matches or exceeds the vessel's installation height. Key technical specs include hull material (typically flame-retardant GRP), seating capacity, and engine performance, which must be capable of running for at least 24 hours at a speed of 6 knots. Additionally, ensure the craft features a self-righting design and a water spray system if intended for tankers carrying flammable cargo.
