Yep, there's a nice 205 just listed here. Super nice boat too, with a 200 and low hours. I think the bigger motor is a must on the tourney, figuring it will get more use for water sports.
Kids will hunker down in the cabin unless it's too hot. And it's a great place to keep gear out of the weather. It all really depends on the type of weather and water you intend to encounter. With three kids you're not going to be out in anything too nasty anyway, a tournament is a great choice.
We really looked hard at them, were torn between for a long time. But the WA won out because of the wind and waves we get out here on the ocean. If we were mostly doing the lake thing, then the cabin would have been a complete waste.
It's really hard to tell how you'll really use a boat 'till you get one. Then things begin to reveal themselves. It's important to buy with the thought that you're going to sell it. That way if you change your mind you don't get killed on it.
The biggest downfall on the 205 is the head compartment. For kids it's fine, and if your wife is more on the petite side and will use it, it will work. It's a much better configuration on the 225, but they are more money still. That's my only caveat on the smaller hull. The potti on the 208 is very usable, but none of this makes much difference to the guys anyway. Just something to consider in keeping your crew happy.
