First Slack [furst slak]
- Noun
1. The first slack tide after dawn on the first day of mini-season. This is the prime time to dive for lobsters because it is the first legal dive without a current since the end of regular season. This means that the bugs are plentiful and you don't have to waste your energy fighting the current. First slack varies between high tide and low tide and time of day depending on the year.
Example: The viz was awesome during first slack this year. You could spot bugs from a mile away.
