Just starting to play S&S and the Enemy Ship henchman has an interesting question for us. It is a barrier that summons a random ship. Is that summoned ship still considered a a barrier for cards that help the check? We played that it wasn't so we've succeeded even if it is, but for future reference, I thought I'd ask. Our decision was based on the fact that the summoned ship doesn't say it is a barrier.
You played it correctly. Ships are support cards ahs neither boons not banes. And even though defeating it will result in the barrier being defeated, the check against the ship is not in itself a check to defeat a barrier.
