More is Always Better
I have boat that has a 6' draft. We are mored in an area that has grass/mud bottom. Last year the lowest water that I was in (saw) was about 7.0 feet (On a real low tide day), which is a little too close for me. Most days the MLLW was just over 8 feet. Our harbor is somewhat protected, but not calm. We also were near a traffic zone, so we would get wave action. This year I asked to be moved to a less traffic area with a little more water. I'll find out tomorrow where exactly and if it has more water.
As a minimum I would suggest a MLLW of no less than 3 feet over your draft if a protected area that receives little wave action. So for your draft I would, think 8 ft ish should be fine. I would go twice your draft for a MLLW if your are in a lesser protected area or your in an area that gets a lot of wave action. If you can get into 10 ft of water with your draft, you should never have to worry about the touching bottom.
Edit: My transducer for my depth meter is on the bottom of my boat about 1 to 1.5 feet below water line, so if my gauge says 7 ft, I am actually in about 8 to 8.5 feet of water. So when I said I say 7, I was actually in about 8 ft of water for 6 foot draft boat.
