So this line of discussion begs the question how low do people allow their tanks to get? I personally keep a fuel log but once the gauges at the helm or sight gauges get below a half I start getting nervous.
I once (never again) ran out of fuel a mile from the fuel docks. I won't go into the reason I bypassed an earlier Fuel Dock. Also, learned bad install of new fuel line was pumping fuel into a bunker, under one engine, so probably had enough fuel leaked off, to get me to the dock. But I still should have taken on fuel, aka cut it too close!.
I have 400gal capacity, so 20% reserve is 80 gals. I doubt I will ever get into the reserve, at least not much. Not after running out. Thankfully was a calm day, so rode at anchor, until tow boat came.
So if "out of fuel" was the issue, esp. if not drawing from multiple tanks, how does a "Pro Captain" allow that to happen? Also, how much time did that captain, if there was one, have with style of boat?
Raises many questions, esp. since would love to have a 75' Hatt!
