Excellent question Capt. Suzy! I see you have been learning the rules
of the road, I understand your urgent need. No since in letting... you

Thats a trick question, submarines do not carry range lights do they
Suzy?

The subs amber light flashes 90 times per minute, and the Hovercraft
flashes 60 times per min.
