I have recently been into Little Harbor Marina in the last month at the wheel
of a Island Packet
31 ,draws 4'9 or so. I saw nothing less than 8 feet on the depth sounder
on both trips.
Pay attention to the chart plotter, there is a shoal at the beginning of the channel as you enter, left side when entering and right side when exiting.
And the Tiki Bar is wonderful to watch the sunsets.
Lastly, a few months ago in the evening a power boat
400hp plus ran into the restaurant at a high rate of speed, possibly got airborne and imbedded itself in the restaurant.
