Avalon/Stone Harbor wakeboarding?

[saltybalty]

Planning a weekend in Avalon in mid may. I have been going here for years, but now I finally have a boat to bring. I found a public boat ramp in both avalon and stone harbor, seems the stone harbor ramp is an easier ride to the great sound. What other stuff do I need to know? I can't find a good depth chart and am basically just looking for any advice from people with experience with the area. Thanks in advance.
