I live in Seattle. So I can state with authority that out here if you want hipster street cred you'll be rocking at least some sartorial remnant of the '70s -- be it a pair of groovy shades, nut-hugger jeans, a polyester dress or booty cut-offs.

What else is reminiscent of the '70s? Hot tubs, baby. And now, chilly (but oh so cool) Seattleites and visitors alike can have a relaxing retro outing thanks to a fab new indulgence: Hot Tub Boats. You and up to six friends (kids count) can bob around scenic Lake Union in a wooden, diesel boiler-fueled floating hot tub boat with full steering capacity and a throttle. All boats come with coolers, locked dry storage, water jets and safety equipment. They are also United States Coast Guard standard approved.

The boats are also available for longer-term rentals and purchase, and can be delivered to alternate locations such as Lake Washington for an additional fee. The company is anticipating a May launch.

Alas, getting nekkid and sipping Lancers is not permitted; we're not animals here in Seattle. And everyone knows drinking and boating (don't) mix. Even though you'll have to leave the booze at home and cover up your bits, there's still something about steamy water, nippy weather and floating on a lake that feels a little bit naughty. Far out.
