[PSUBS-MAILIST] Ethical obligation to inform

[Jon Wallace via Personal_Submersibles]

Hi Brian,

It looks to me that Rule 24(g)(i) of USCG Navigation Rules would apply 
to submersibles.  See https://www.navcen.uscg.gov/?pageName=navRulesContent

The rule is that the light must be seen from a distance of at least 3 
miles.  So height would be determined by line-of-sight between you and 
whatever vessel might be around to observe you. The higher the target 
vessel observation deck, the lower your light needs to be.  Assuming the 
target is a kayak with passenger eyeball height at 3-feet (sitting 
position), you would need your light to be one-foot high above the 
water.  Depending upon the buoyancy of your submarine you may not need a 
mast at all.  See http://www.calculatoredge.com/electronics/lineofsight.htm
