firstly, i check is the variable empty or not, if so

vesselNameList=`echo $vesselName`

if not

vesselNameList="${vesselNameList}""\n"`echo "$vesselName"`

and it produces this result

BUNGA TERATAI 3 5055\
JADE TRADER 143W\
MOL SPLENDOR 0307A
BUNGA TERATAI 3 5055\
JADE TRADER 143W\
MOL SPLENDOR 0307A
BUNGA TERATAI 3 5055\
JADE TRADER 143W\
MOL SPLENDOR 0307A
BUNGA TERATAI 3 5055\
JADE TRADER 143W\
MOL SPLENDOR 0307A
BUNGA TERATAI 3 5055\
JADE TRADER 143W\
MOL SPLENDOR 0307A
BUNGA TERATAI 3 5055\
JADE TRADER 143W\
MOL SPLENDOR 0307A
BUNGA TERATAI 3 5055\
JADE TRADER 143W\
MOL SPLENDOR 0307A
