The new forums will be named Coin Return (based on the most recent vote)! You can check on the status and timeline of the transition to the new forums here.
The Guiding Principles and New Rules document is now in effect.
What kind of boat are you looking for? I'm guessing you're interested in a small powerboat or something like that. I can't give you names, but I've ridden in rental motorboats on Lake Washington, so don't give up hope looking. I also took sailing lessons in Kirkland, like, 10 years ago, and I'd imagine that they rent small (20-ish ft) sailboats if they're still around.
If you were looking for something smaller, there are canoe and kayak rentals all over the place, but one of the most popular places is at the University of Washington stadium.
edit: are you going to have a car? If you're relying on public transport, the kind of places you can get to might be limited (e.g., downtown Kirkland probably not as great of an option).
If you're looking for recreational canoe/kayak boating here's some options not too far away and easily accessible by bus. The 5-day forecast isn't looking so promising right now though.
University of Washington Waterfront Activities Center - Located behind Husky stadium on Montlake, this is also available to the general public and your cheapest option. http://depts.washington.edu/ima/IMA_wac.php
Agua Verde Cafe & Paddle Club - Montlake, rents kayaks and has Mexican noms! http://www.aguaverde.com/
Green Lake Boat Rental - One of Seattle's finest summer parks! Kayaks, Canoes, Bicycle Boats, Sail Boats and Stand Up Paddle Boards. http://www.greenlakeboatrentals.net/
Really depends on where you want to hit the water.
Lake Union:
has several hourly (or more) trip type things down there, one of the major players there is Argosy: http://www.argosycruises.com/
they also do trips in the sound and a dinner cruise I hear is pretty fun.
Also on lake union is the electric boat company.. small crafts.. and limited travel area.. but does get one on the water: http://www.theelectricboatco.com/
Advantage of some of the lake union options is one can hop on the Seattle's Train that goes out there from near westlake center.
Puget sound:
Argosy again.. see link above.. and not sure who else..
but one can hope on the ferries too as a way to get out on the water.. (and probably the cheapest option)
