T or F A competent ship handler can anchor safely in any anchorage and never has to lay off for conditions to improve.
False
Anchoring is one continuous evolution and considering it in parts makes it unnecessarily complicated.
False
Allowance should be made one degree at a time for set and leeway when maneuvering at slow speeds in anchorage.
False
Think in increments of 5 to 10 degrees
A ship moving at 3 knots moves about _____ ahead in one minute.
300 ft.
A ship 600 feet long moving at 3 kts would require about ________ minutes for her entire hull, bow to stern, to pass a fixed point.
2
A 1 knot current on the beam sets a 600 foot ship about _____ feet in that amount of time
200
T or F A ship can turn and maneuver to depart from a crowded anchorage be heaving short and maneuvering on her anchor.
True
Ships lie at anchor on their final heading
lying to the result of all forces acting on the ship
List 3 reasons why it is preferable to have the ship on her final heading before letting go.
- The chain leads clear of the hull as it is slacked out
- Wear and strain are minimized
- The chain is laid out on the bottom neatly and quickly
- The ship can be positioned among other ships without concern about swinging clear after the anchor fetches up
T or F The difference between apparent motion of closer ships or objects and farther objects or the shoreline can be used to accurately detect lateral motion ahead and astern.
True
Go astern to estimate ships speed through the water ________ the final anchoring location when anchoring _________.
before reaching
at night
T or F Always place the anchor halfway between ships anchored ahead and astern so your ship will lie at an equal distance from all ships when your anchor fetches up.
false
Ships at anchor always appear ______ your ship than the are actually lying.
Closer to
T or F It is unusual for anchors to be used in day to day ship handling because anchors are inefficient with today’s larger ships
False
T or F Its important to use proper amount of chain when handling a ship with her anchor used correctly, the anchor will drag along with considerable resistance, but it won’t dig in and hold
True
