I have some difficulty relating lumen to candela.are these lights focused so
that all 800 lm are directed.the correlation is usually stated by 1 candela
= 12.57 lumen but with this calculator:

 

http://www.rapidtables.com/calc/light/candela-to-lumen-calculator.htm

 

300000=64228 lumens at an apex angle of 30 degrees so

 

What does 800 lumens actually look light, bright for distance I mean?

This is what I use, as well. But I  did not buy these lights specifically
for sailing; rather, I use them extensively when XC biking at night. You can
get some very bright lights that can be used as headlight or mounted for
under $50. I have one that claims 800 lm; from my experience it is more like
500, but still quite bright. Look for Cree-T6 headlight. Amazon has a bunch
of them; some claiming 1200 or even 1800 lm. They are quite bright, but they
run hot.

We have a really nice cordless 300,000 lithium ion spotlight. I forget the
brand but it holds a charge for well over a month. It is great for
spotlighting markers or buoys, but you must never light up the deck. Instead
we buy the camper's or biker's LED headlamp and that works almost as well. I
think I have 5 on the boat and have given another 5 away as gifts to other
boaters. Once you have one, you'll see how useful they can be. I also have
battery powered LED Puck lights in at least 8 locations on my boat, and they
last a season on 2 AA batteries each. I buy them from Harbor Freight or
WalMart.
