The French think the number is 3-1, the Americans think 7-1 always measured from the stem to the bottom never what the depth sounder might say. Heavier chain could lower the amount of scope needed. All that is meaningless in White Bay or any crowd of boats. To keep the boats from banging together everyone must use the same scope or anchor line length. So if you show up and anchor in a crowd you must make match their scope. If someone comes along and joins your crowd all the boats should make the changes to end up with similar scope. That is why White Bay is s mess in a sudden series of microburst and why prudent boat owners and their captains never paint themselves as I into the corner. The it's a rental crowd does it everyday.
If you must... very short scope and always be ready to leave in 15 minutes or less.
