Nick,
it's more like you catch more sharks with forum posts than blood in the water.

I think the 60-70 MPH part of you plan is definitely pushing the bounds of safety though,, As you know a lot can happen at that speed on the water.

About 15 years ago a buddy and I took my boat to lake Mead,, It was my bachelor party weekend in Vegas baby,, He brought his Goldberg Cub to fly,, he flew it while I drove the boat 35-40 mph,, it was very cool as the plane was right there next to the boat as we scooted along the lake,, I wish I had video,, Good times

Good luck,, be safe
