Hi Allan

You've done everything right so far. The seat should be as low as you can get it, and should fit the backside to where you are comfortable with no noticable hard spots. What you can do is add some padding to the front of the seat or out in front of the seat to give your thighs some lift. That has been the usual cure for most folks having this problem. And yes, it's very common. How long is your seat?
The accepted angles for chairs and so forth are 7* tilt back for the seat back, and a 3* tilt for the seat itself. This is for about any chair made, and will apply to your seat in the boat as well.

Look for some interesting conversations in the archives listed under Numb-Butt Syndrome. It's been covered a few times and most have found it to work very well.

Hope this helps!
