I'll give you a clue..!
140'... 140kts...
After faffing around with flame floats for a while..
"Beam, Capt, when I say Mark drop one flame float.."
"One gone!"
"Not yet you eejit!"
ad infinitum..
Pretty sure the Lindholme was dropped upwind so that the MS9 would drift down towards the survivor(s).
Happy days!
