Dave did a good job of summing things up. Depending on the spacing of the boats in the line you may also be able to hand your anchor line to one of the boats that are next to you while you drop out to fight a fish. Also if it's your first time, you probablly don't want to try hoggin up alone. one at the motor and another on the bow with the anchor will make it a bit easier. As previously stated, look at the angle of the other anchor lines and don't cross them.
