Boat license allows all people on the boat to crab, but you are limited to the # of bushels you can keep by the # of licenses.
For example, if you have a boat license with three people who are unlicensed, you are limited to one bushel.
If you are on a boat with a boat license and one other licensed rider, and two unlicensed, then you could keep two... and so on...
You might want to call but I believe if you only have the one license (the boat one) than you are only allowed to keep one bushel.
If only the captain of the licensed boat was licensed yes. If other licenses are on board, then no.
Would you really need 3 bushels of crabs?
Three guys on a boat, each returning to their families with a bushel of crabs, is reasonable to me.
