    Construction and stiffening of watertight bulkheads.
    Collision bulkhead.
    Stern frame and stem and how secured.
    Stresses and strains in ships through effect of seas or
    loading and ballasting.
    A knowledge of those portions of a ship specially
    strengthened to withstand such stresses, or where excessive
    damage by corrosion is liable to occur.
    Rivets and riveting. Testing a line of rivets. Testing
    watertight work.
    Rudders and steering gear. Inspection and maintenance.
    Hatches and hatch gear. Hawsepipes and cable lockers.
    (b) Buoyancy and reserve buoyancy. The righting couple when
    a ship is inclined. Metacentre and metacentric height.
    Transverse and longitudinal metacentres. Stiff and tender
    ships—how to obtain stiffness. Stability at large angles
    of inclination and what this depends on.
    Preparation of data for ascertaining metacentric heights
    of a ship in any particular condition.
    Determination of centre of gravity of a ship in any
    condition, the centre of gravity in light condition being
    given. Use of stability curves and data supplied to a ship.
    Alteration of stability during a voyage. Effect of shifting
    cargo. Change of trim.

    lifts, &c. Strength of ropes, chains, slings, two slings at
    an angle, &c. Purchases and power gained by purchases.
    (d) Cargo work.—(The candidate should, where possible, illustrate
    his answers from his own experience.)

    and dunnage. Deck stowage. Possible damage and its
    avoidance.
    Good and bad stowage. Special cargoes—explosives,
    grain, timber, oil in bulk, steel rails, &c.
    Given a cargo list, to stow a hold or holds, making a
    rough cargo plan, with a view to stability of tender and
    stiff ships, damage and contamination, easy handling and
    possible optional ports of discharge.
    Methods of ventilation of cargoes. Drainage of holds.
    Closing of hatches. Cargo working gear—derricks and
