log: SOG V Water Speed

[Guest]

I agree, of course, but having speed through the water and SOG avaialable allows you to compare the actual affect of set and drift with predictions. You can then take that into account in constructing the EP therefore achieving a more accurate prediction.

Re: SOG = SPEED

As the master of yor vessel you are clearly responsible for complying with regulations - if you only have a speed through water log then you will obviously have tidal atlas almanac etc and a calculator (slide rule?) from which to calculate your SOG as any navigator......but, as said earlier in this post and many times before, you will normally stick out like a sore thumb to both your self and the authorities before anyone goes pointing a radar gun at you.

Above all we are all supposed to be enjoying this sport!
