Any king of boat. There is a large ramp that is 5 or 6 lanes wide. You will have to be careful of submerged trees in the lake is all.

The Schoolhouse campground sits right next to a boat launch area. Roosevelt lake is huge and they allow all types of power boats.

I didn't have a boat, but there were electric and motor fishing boats.. tiny to big. There are house boats on the other end of the lake... so I guess no restriction?
