Yes, those are right. I know this because I am having nightmares almost every night and in my nightmares I get quizzed just as I am about to step onto the ship...if you don't know the terminology you go back to the end of the line. I have been sent back to the end of the line a lot...but I do know those 4 words now. Last night I had to know how to tie some kind of knot and spent the whole night at the back of the line. I'll never make it on my cruise!
All your definitions are correct, but with the understanding that they apply only when you're facing the pointy end of the ship (forward).
Others (with a bow to our friend, the late Pamda):
rope=line (you NEVER say "rope" on a ship)
knot=nautical mile per hour (1.15 land miles per hour)
knot=something you tie in a line (or lines)
course=the direction in which the ship is sailing (as shown on the compass)
intercourse=same as on land
its decks not floors
cabin or stateroom not room
head = bathroom
the Captain navigates from the bridge, he does not "steer" the ship
cabin steward not maid
the ship docks it does not park
its a ship not a boat
