My wife and I both grew up on the lake and have been on boats all of our lives. This is a good thing in that I don't have to worry about doing everything on the ramp, didn't have to teach her how to drive and load the boat, and can kick back and relax knowing our boat is in good hands! The bad part is her back seat driving carries over to the boat. Our argument this weekend was a safe depth of water to pull a skier. She freaked as I drove across a point with 10' of water. She says it is too shallow and we are going to ruin a prop. I tell her that we idle though a section of our lake that is 6' to get to our riding spot and at speed, a boat sits the same if not higher in the water. She says the opposite! She thinks that a boat sits the same, if not deeper in the water at speed. The argument ended with both of us saying we really didn't know for sure and was no reason for a divorce! But, for safety sake
, what is a minimum depth for a Supra 21v? Does the draft increase or decrease when a boat is on plane?
