On the way north in the spring of 2001, we stopped here, and we stopped again going both ways for the 2001-2002 trips.
The radio is monitored by the office, and transferred to the dockmaster. He was blurry on his handheld (loud enough but hard to understand). He first told us we would be 'beside' the black boat, which I at first thought meant rafted on. But he really meant 'ahead of'. Maybe a local way of speech.
Transients (especially large boats) are mostly on the face docks. We were tied up ahead of a big black wooden sailboat,and a big power boat was put ahead of us.
Bob walked up into town - the marina personnel told him where he could find a hardware store and he walked there and bought lamp wicks for the new lamp he got in Fernandina (spring 2001). There were azaleas in bloom, but it is cold. The ramp up to the bank is very steep at low tide (we are on floating docks and the tide is about 8 feet). I was allowed to use the fax line in the office for email. All people were very helpful.
Equipment: Rates were $1.20/ft/day or 90 cents/ft for the week, 8:50/ft for the month or $7.00/ft for the year. They noted that weekly and monthly rates may not be offered during the transient season. A shrimp boat came in and tied up to the floating docks around sunset, and left at sunrise. Don't know how(or if) they paid.
Electricity and cable TV were included in the daily and weekly rates. Electricity is $70/month extra (called a live-aboard fee) for 30 amp. They say they also have a store, phones, a pumpout boat, ATM, and courtesy car for getting groceries. They allow an hour for the use of the car, but they don't like it if you go to the closest grocery store because that is across the Ladies Island Bridge, and sometimes people get stuck on the other side when it opens and can't get back within the hour.
There is an anchorage right off Beaufort that a lot of people use.
The seawall is 50 cents/ft /day. Boats can tied up during the day for free, but after 5 pm, they have to register at the marina office and pay the overnight fee. I don't know how they do that, since the office closes at 5.
I wouldn't do the sea wall since the tides here are almost 8 feet, and I think it would be hard on your lines and fenders to tie up to a wall.
I think you can land your dinghy at the marina
