Hi 541
It's been awhile since being R C , -
-iDEALLY - set the line slightly Port favored , --this avoids a pileup on the com .boat ,
Set the A mark slightly startboard side favored ,--ideally boats that hit each layline --both directions arrive there at the same time .
-If there is current ,-or higher winds and seas a two boat length line for each boat is recommended . -
Always check for drag on com boat , you can use a GPS .
AND always check a chart for obsticals and depth ,-
once through out an anchor and mark with 150 ft line only to watch it disappear below the surface , it was more than 250 ft in Traverse Bay . -
oops -ran lots of A -C courses that day -
have fun -
