I have a Walker Bay 8 that I used with my former boat, a Cal 29. Now it's my daughter's first sailboat.
The Walker Bays row and tow nicely. It's also easy for one person to put up on the roof of a car. One mis-step getting in, though, and they'll put you in the drink (I was once the evening entertainment in the anchorage at St. Michael's, MD). They can't haul much, though I know for a fact that the 8 can handle three drunks if the water is calm enough.
Also, the Walker Bays gouge easily. The plastic is soft. You're supposed to be able to "fix" them with a hair dryer, but I haven't tried that yet.
For my current boat, I bought a 10ft inflatable with an air floor and I think it's a much better thing to have.
