Ah, I see everyone's too shy to post, so here are some manufacturers of various 15mm (1/100th scale Pirate and/or Sailing Vessels):
Old Glory (and Blue Moon 15mm vessels, crews, and cannons)

Peter Pig (for ship's boats, cannons, and crews - they used to recommend/carry 15mm vessels from SDD [now Stronghold], but now only sell smaller 1/450th scale vessels)
http://www.peterpig.co.uk/range10.htmSailpower (they produce a set of naval rules for 15mm scale vessels, as well as the ships and boats too - lots of great photos of assembled and painted vessels on their website)
http://blog.sailpowergame.com/?page_id=766Stronghold (not sure if they are back in operation, but they were the last manufacturer to produce the old SDD 15mm range of vessels, a schooner, a brig, and a frigate, as well as native vessels, a ship's boat, etc. - rumor has it they are trading at some UK shows, but I don't know if the resin vessels, and other items are available from them. They are also a source for the resin, 25mm Village Green Pirate Vessels, but again, I don't know the availability status of those. Best to inquire with Stronghold directly, or someone with current intel can reply here). See page 15 of the PDF below:

http://www.stronghold-miniatures.co.uk/Thoroughbred (really for the War of 1812, but who's counting - boats, cannons, and crews)
http://www.thoroughbredmodels.com/SeaEagles.htmSadly, the superb Opus/Tiger Terrain vessels are not currently available. Hopefully, they will be again at some point in the future.
Feel free to add in any 15mm scale vessel manufacturers I may have missed.
Of course, I'd love to see some of your nice scratch-built, or converted vessels too. I suspect there are a lot more 15mm scale Pirate gaming fans than the info about them on this site would indicate.
Greg recently posted a link to a lot of nice wooden display ships that he will be using for his upcoming giant pirate game, early next year.
