No, but I recommend the following vessels:
The Sea Dog for your Pirate Sloop:

Various ships from Old Glory would work for your Dutch vessel, especially their nice, large Indiaman vessel. If you're on a budget, but still want a nice pirate hunter, you can go out of period, and purchase their French Corvette or American Cutter, which would make a nice brig too:

They also have a sloop, brigantine, and other vessels as well:

Pricing includes cannons, so is less than it seems at first, once you factor that in.
If you sign up for their Old Glory Army, you get 40% off your purchases, so I recommend that when moving forward on miniatures and ships - they have pirates, government troops, natives, vessels, etc. and all at very nice prices.
Scale Creep also has a couple of nice sloops too.
