Crabbing with a trot line down here is tough because the currents are really fast.....in my 13 years down here, I have never seen a trot liner.....Former Marylander, crabbed a lot in the Wye River and we have the Jimmy's down here you don't see a lot of in Maryland anymore. Laws are a lot different down here...there is no such thing as a commercial sportscrabbing license...they call a pot a trap and a trap a pot...DUH! We used to crab off a pier in Georgetown, you need 10 oz of lead on a "collapsable trap" to keep it down since the water runs so fast. Bought a boat to put out collapsable traps (15) of them and had to go commercial all the way....5" x 11" floats with you license number branded in....your own two color combo on the floats, 6" x 8" numbers on the size of your boat also with a circle with the color combo of your floats.....and $50 for the license. Then, u are restricted (being commercial) from placing those traps in many of the creeks. Last week I crabbed in the Inlet across from the Veterans Pier (near the marsh walk) and got 6 dozen in 2 1/2 hours, mostly females....went last week into Winyah Bay in the boat, and caught just about a bushel in 3 hours...but u need all of the above....mostly males, lots of doublers.....
I have crabbed that pier in Georgetown several times in the past, that current is crazy. I would try to put the trap in front of a piling to cut down on the current. It really moves through there...
