Nothing from Annapolis but I did drive over to Toronto today to order a new UK Halsey Mains'l.

Knowledgable and helpful people there. I met with them at a couple of recent boat shows and they seemed to be the best combination of quality, knowledge and price IMHO. I think all of the UK Halsey sails are made in Hong Kong. Seems odd to have a business that needs lots of square footage in some of the most expensive real estate in the world but that's where they are. The UK Halsey loft owner in Toronto said he has been there several times and it is a huge area on approx the 22nd floor of one of the hundreds of high rises in Hong Kong.
Next on the agenda (maybe next year?) will be an Asym. I think the UK Halsey version has the unfortunate moniker of "the flasher".
Good luck... let us know what factors swayed you toward UK Halsey or whoever you go with.
