@matmoesa yes it sinks slowly with only a few holes, but its an awful ship. Have fun not dying, not getting boarded, or knocked off your ship when your single mast gets chainshotted even once. A gally gets 4 cannon shots at once to down your mast, you get one cannon to down three.. To avoid getting broadside, you are forced to keep your distance and wait for the perfect moment, which to me, just sounds like you are playing with the weaker ship. If you have anchor balls, balast balls then sure, you have a secret weapon, but those are hardly a balancing force.
Everything you said is applicable to all ships, but you need to do those things to the other crew with only 2 people and 1 cannon, while not sinking. I maybe down 10% of ships without boarding, but against competent crews that number drops to 0%.
Sloops are also pitifully slow, so even if you decide you want to try your luck as an aggressive ship, you wont even catch a brig or gally unless they are dumb and head into the wind. Even if they do this, you will end up getting broadsided or boarded during this snail chase.
Sloops are bad, the only thing that makes the good at times is when other crews are uncoordinated messes. You do find that a lot, but against other experienced player, the extra firepower and crew members are significantly more valuable than maneuverability and sinking a bit slower.
But I won't convince you here, only at the other end of my cannons will you see the folly of your ways.
