Yes, you can set your draft

It just doesn't seem to use them consistently. Sometimes it'll route me over rocks I just barely clear, while other times it'll route me the long way around deeper rocks which really pose no threat.
If there is a "distance off" setting, I'm not sure if I'd want to use it. There are passages in protected waters which are safe even very close to shore, while outside I'd want to be much farther away from the same depth contour.
Again, the solution is to review the route closely, and edit or simply deviate from it as needed.
I would hope Garmin
(and the others) are improving their algorithms all the time, and these discrepancies will become less of a problem over time. But that leads into the discussion (from another thread) on how Garmin doesn't support one-year-old "legacy" hardware
with firmware upgrades.
