I have heard about 2 local holiday events that are "water" based for people who are looking for something like this to experience this holiday season.
In Everett, the Christmas Lighted Boat Parade is on December 12 and 13th from 5pm - 8pm. This parade features boats of all sizes that are beautifully decorated and in our backyard. For more information on an exact location, call 425-259-8178.
Downtown, Argosy Cruises offers an array of holiday sails in the month of December until the 23rd. Cruises featured are the Santa Brunches and family dinner cruises. A complete list can be located at http://www.argosycruises.com/themecruises/xmasSchedule.cfm#schedule. This list also provides information on the choirs that will be caroling during that sail. Reduced priced sales are listed as value nights and can provide a savings if you are flexible on when you can go.
Check it out and set sail this holiday season.
