You are sailing about in a Hornet and are expected to best the other captains.
Click on the nearby boat to get started.
Be careful and wait before enabling friendly buffs, until after starting.
Sink 10 Gunboats in 10 Minutes.
Strategy Hint: Between your nose Cannon and Swivel Guns, tag as many of the other captains as you can. You do not need 10 "kill" shots to still count. Use tab key to cycle through who's hurt the most, since once sunk, they will respawn. Good Luck!
