jeff, if you have to deal with tide, then do the drift with the direction of the tide-it is always good to have wind and tide together, btw! hehheh--small mushrooms, with a bit of chain are probably going to be fine if you do not have much of a tidal swing---
ALWAYS remember, when you are feeding the line from your longlines into a bucket, always clip each line to the next one, and clip the last clip to the handle of the bucket, then put the lid on---no matter what happens, those lines will NOT tangle up on you!!!!!!
when we layout shot, we set the boat, then worked the dekes around the boat, usally making a pos with lines going away--gave the divers a string to follow.
First time is usually best done before you are actually gunning, so you can work out the logistics==even so, there are always little glitches here and there.
Enjoy, and have fun!
