Record 1 |
‘FORWARD’ |
Character string 'FORWARD’ - may be shortened to 'F’ |
|
Record 2 |
NFR |
Number of Froude numbers at which data is given |
|
Record 3 |
Fn BOWF BOWA STRNF STRNA |
where Fn is the Froude number. BOWF is the percentage change in thrust for bow thrusters at forward speed. BOWA is the percentage change in thrust for bow thrusters at negative speeds. STRNF is the percentage change in thrust for stern thrusters at forward speed. STRNA is the percentage change in thrust for stern thrusters at negative speeds |
|
Record 3 is repeated NFR times. |

Record 4 |
NH, |
NH is the number of inflow angles at which steerable thruster reductions are given.
