Just push a button and your two hour boating party is launched. Up to ten adults will fit comfortably in a 21' Duffy electric boat, which is equipped with two tables, cup holders, CD player and sound system, and plush leather seats.  Refreshments are included.  If the weather is beautiful the boat is open for maximum exposure.  No worries about rain or chilly weather though because the boat also can be completely enclosed. Explore Lake Union as you wish.
