Corsairs have always been the toughest adversary of the regular enemy ships, ounce for ounce. Juggernauts are just as deadly, but much larger and more powerful. They both can sink ya easy if the full broadside hits.
In addition to that excitement, yer always gonna have crew mates shooting at everything in the water, expecting the capn to make miracles happen. And yes, the crew will always shoot at the Corsairs...
A good capn will balance the crew's exuberance with the deadliness of Corsairs. Tell the gunners to stay on one side, and always position the ship so the Corsairs are on the other.
A good war brig can easily take out a Corsair, if the shot hits.
Otherwise, RUN!
Savor it!
