A couple of question (Of Unknown value)

When saling on a Lake; Is it knots or MPH?
Not sure, but on the Erie Canal and ICW statute miles are so prevalent the we
switched the log to read in miles and mph.



Is there a varying Current on a Lake?

Depends - some lake are even tidal. ANd some have currents that are dependent
on rainfall, etc.



Things I'd like to know;

On a water Ballast Vessel, can you reduce Ballast when floating level?
Yes, but on many its considered dangerous - consider the affect of 500 pounds of
water sloshing in the bilge!


If so, how is it done?

Thanks,
Ole Thom
