My wife and I have looked at the Seville 37 at the Seattle Boat Show in both 2007 and 2008. Very nice boats, really well finished. They are planning on introducing a two stateroom version using some area forward of the engine room. We met the owner during the January 08 boat show...very nice guy and quite affable. He is in China almost every month to insure quality and production schedules. I was told they have a "dedicated" yard in China rather than using the large yard in Zuhai. I think they would be more than happy to work with buyers to tailor a boat to whatever is desired. I did not like the fact that there were no side decks but that is pretty much becoming a standard among pilothouse designs.
Roger Drill, the once manufacturer/owner of Pacific Trawlers (the 37' and 40' pilothouse trawlers) is now working with the Seattle based brokerage for Mariner Yachts. http://www.islandyachtbrokers.com/
The Seville 37 doesn't come with quite as long a "standard" equipment list as the North Pacific 39. The North Pacific is priced better too. We took a very serious look at the North Pacific and at $289,000 it is a standout, big time bargain. The North Pacific also does not have side decks. You access the dock from the cockpit or from the forward deck. It is a long jump to the dock from the deck adjacent to the pilothouse. We also met the owner of North Pacific, Trevor Brice, who is very deeply involved in his business and very knowledgable.
Good vibrations from both companies.
