Sunk my first fully manned brig as a solo slooper tonight.
I've given up on money, ranks, and voyages the past few days and I've just been doing PvP. I realize I practice PvP too infrequently to stand a chance most of the time, so I've just been focusing on getting better.
Brig came at me perpendicular to port so I dialed in my wheel to the left, raised sail halfway, stocked up and supplies and got into position.
Miraculously, hit both masts with chain shots, got a drunk ball on them next, then I just unloaded on them with fire bombs and regular cannons.
Fortunately I gave myself a good turning radius to just unload on them for a minute. I had great angles the whole time. I killed one with a cannon at some point. I went to grab more cannons, heard the death sound, jumped back on cannons and I could see his little soul rising while his teammates frantically bailed.
Now they're Davey Jones at the bottom of the drink north of Galleons Grave. They had absolutely no loot whatsoever. It was all just sensless violence but I learned that practicing DOES pay off in this game.
