The following description comes from the event organizer.

Celebrate America's Birthday the best way we know how - on the water! Spend Fourth of July on Lake Union and see the amazing fireworks show from our boats. This year's events are 21+, so get ready to say cheers and hit our full-service bar all night long! No need to scramble for plans or rush to find seats for the show, our boats have a great view. Choose to party with us all night with our 4 hour cruise departing from Kirkland or hop on a boat just in time with our 2.5 hour cruise departing Lake Union.
