If your crew enters an enemys dep.point. you choose a zone where an enemy objective or Hero is..no matter on which ship they are...if you remove 1 deckhand and 1 bosun for example you roll 2 dice and need a 3+ to hit
I would assume that is the intent of the rule, but as written it clearly states
"If Crew would ever move onto an enemy Deployment Point
(from having reached the end of their movement track) they
have pushed as far onto the enemy ship as they can go, and
now disperse in a mad rush of pillaging and ransacking!
Remove all Crew from that zone. For each Crew removed,
make 1 attack targeting a zone containing an enemy Deck
Feature or Hero on that ship. These attacks Hit on a 3+."
So some clarification is necessary.
