1) If a player is attacked by another player and decides to "cut loose" his Prize ship in hopes of making a speedy escape, can the attacking player now claim the Prize ship and any cargo that it was carrying?
2) During a combat between players, after the Broadside phase the winner of the phase decides to "sink" the loosing player's ship. Does this leave the sunk player's Prize Ship available to the winning player? Or is a successful Boarding phase required to capture a Prize Ship?
You must board in order to capture a prize ship that has not be abandoned.
