25 Adding a ship to a scenario

26 Running Scenario Builder –demo scenario Liverpool Scenario 1 Using a scenario in another, new scenario. Use scenario Liverpool Scenario 1. Adding a new ship to the scenario –create simple paddle steamer XXX –demo scenario Sailing XXX Use scenario Liverpool Scenario 1. XXX is a British ship. At 06:00 XXX is at P. At 06:18 XXX docks unassisted in Liverpool Docks at berth Albert Dock 1. Adding a ship to a scenario

At 06:18 XXX docks unassisted in Liverpool Docks at berth Albert Dock 1. Adding a ship to a scenario

29 The Liverpool Scenario At 06:00 XXX is at P. At 06:18 XXX docks unassisted in Liverpool Docks at berth Albert Dock 1.

30 Adding your ship to the scenario Use scenario Liverpool Scenario 1. XXX is a British ship. At 06:00 XXX is at P. At 06:18 XXX docks unassisted in Liverpool Docks at berth Albert Dock 1. How do we change this so we can see your ship instead of XXX?

31 Adding your ship to the scenario Use scenario Liverpool Scenario 1. XXX is a British ship. At 06:00 XXX is at P. At 06:18 XXX docks unassisted in Liverpool Docks at berth Albert Dock 1. Open ScenarioBuilder Select menu item File | Open Scenario and open Sailing XXX in examples folder

32 Steering your own ship Use scenario Liverpool Scenario 1. XXX is a British ship. At 06:00 XXX is at P. XXX is manually controlled. Controls for your ship Demo

33 Steering your own ship knots (sea miles per hour) 1 sea mile = metres sometimes called a nautical mile

34 Steering your own ship heading is direction measured in degrees from the north direction

35 Heading North Heading 000 Heading 090 Heading 180 Heading 270

36 Sailing towards Albert Dock from P About 150

37 Sailing towards Irish Sea from P About 330

38 Sailing towards Liverpool from Q About 060

39 Sailing through the Liverpool Scenario Try sailing your ship from P, then Q then R

40 Part 3 Turning a ship

41 Turning a ship Ships, like cars, need a bit of room to turn round

42 Turning a ship What shape is the path the ship follows?

43 Turning circle

44 Turning circle What features of the ship affect the size of the circle? Radius

45 Turning circle In Builder we first assume: Radius = a * Length of ship Radius

46 Turning circle In Builder we first assume: Radius = a * Length of ship Neater to say R = a * L Radius

47 Turning circle R = a * L Radius Try out different values of a for our ship.

48 Turning circle In Builder we next assume: R = a * L + b * S where S is the speed Radius

49 Turning circle In Builder we next assume: R = a * L + b * S where S is the speed Try out different values of b for our ship. Radius

50 Turning circle R = a * L + b * S This is an example of a mathematical model We are using mathematical symbols to represent the real world This kind of model is an equation
