ood the distance from the waterline to the highest point of the vessel. When proceeding through a channel that is spanned by a bridge, the air draft should of course be less than the vertical clearance of the bridge. When a vessel's air draft is greater than the vertical clearance will allow, we speak of a top-hampered vessel.freeboard is understood the distance between deckline and waterline.underkeel clearance (UKQ) is understood the distance between keel and seabed.
How do they call the inside width of a ship?
When is it especially important to take into consideration the beam of a ship?
What do the port authorities have to know the ship's LOA for?
What is the construction waterline?
How do you think, why is it that important to distinguish loaded draft and light draft?
How do you think, where can be the highest point of the vessel? Why is it so important to know this?
When is it necessary to state your freeboard? What for?
What is the best (or the least) under keel clearance according to the well known saying?
Exercise 12. Correct the mistakes and give right definitions
In shallow water the vessel's beam is an important factor to obtain a clearance to proceed.
Before a berth along an embankment is allocated, the port authorities will have to know the total width of the ship.
Due to the salinity of seawater, the draft in seawater is greater than draft in fresh-water
When a vessel's draft is greater than the vertical clearance will allow, we speak of a top-hampered vessel.
The fore-perpendicular is the diagonal line through the point where the Construction Waterline and the stem intersect.
