The great outdoors is a sensory oasis where bodies can feel the tickle of grass, the crunch of gravel, and the underground rumble of an oncoming T. rex. Escape into the natural world with today's Groupon: for $98, you get a two-hour electric-boat rental at The Electric Boat Company (a $194.95 value, including tax). Voyages begin at the Westlake Landing Building on Lake Union.

The Electric Boat Company outfits customers with Duffy electric boats and sets them loose on beautiful Lake Union for self-guided watercraft fun. The Duffy cruisers hold as many as 10 guests and are equipped with two tables, beverage holders, and a sound system that connects to both the on-board CD player/radio and personal iPods. Clad in leather seats, these 21-foot floatables can be fully enclosed and heated, meaning boaters can make a sporting day on the lake regardless of the weather's moody inclinations. After a 15-minute registration and procedures lesson, captains of all skill levels can dock and sail across the waters of Lake Union and the river Styx. Set-sailors can pack a cooler with snacks and congealing chemistry projects, pick up forgotten ice and drinks at the on-site snack shop, or satisfy appetites at one of 12 restaurants accessible by boat, including Ivar's Salmon House, McCormick & Schmick's Harborside, and Chandler's Crabhouse.
