    Phase 1 Cradled Position
    • 1. take proper muster
    • 2. secure boat plug
    • 3. ensure releasing gear lever is in locked position
    • 4. lober man ropes, rigged to run free

    • 6. check tricing pendants
    • 7. Pass sea painer, ensure that sea painter is lead under gripes adn tricing pendants (inboard the fall outboard off all)

    2. remove harbor pins and keel lock

    3. ensure ladder and falls are free to run; trackway clear of debris

    4. release gripes (outboard/inboard gripes - release outboard gripes first)

    5. check that all personnell are clear
  3. Rapid Lifeboat lowering -gravity davits
    Phase III - Lowering to the Embarkation Deck
    1. raise brake to lower boat, watching running rigging, sea painter, and tricing pendants for fouling

    2. stop boat at embarkation deck ensuring all strain is not taken up by tricing pendants

    Phase IV - lowering from Embarkation Deck to Water
    1. raise brake, tending ladder and man ropes
