Last year, we were the second boat in at the Duck Club. Seeing Discovery get nearly sideways gave us an indication of just how strong that current was. We were able to get an aft dockline on first, and that got the boat lined up... but it took nearly full power in reverse, with full port turn to get it there.
The problem lies in the way most of us dock: at low speed, you have little steerage. In this situation, you need to have some power on as you come in to maintain that steerage. Once two boats are in and secured, and you have crew to "catch" at the dock, the problem is lessened.
My take on last year's situation is that as each boat came in, they were nearly power off, moving swiftly with the wind and current... and then got surprised by the lack of steerage (hey, it feels like you're moving, but it's with the current). It takes a lot of trust to think that strangers are going to grab that dock line as you put the bow to the dock. To make matters more interesting, the docks are a bit... um, unsteady (put three people on the end of the dock and it starts to slope). The breakwater to the outside (with the rocks) can be intimidating.
The duck club big boat was in the middle of the dock and had to be moved. So, the first boat or two in have plenty to do to prepare for the rest.
My suggestion: send the strongest docking crew or two in first. It is going to take some nimble moving on the boat and the dock right at first. Know that there will be some movement in the dock as you get off the boat. Put a stern line on first. As each successive boat comes in, keep room at the head of the dock, so the incoming boat can line up with the dock... then move them into the raft with lines. Arrange fenders for docking, then move them as necessary for rafting.
It helped last year to have a handheld radio on the dock for instructions, but you are still in charge of your boat. If you put the bow just past the corner of the dock and have a stern line ready to hand to someone on the dock, the boat will be much more controllable. If you turn off from the dock too soon, be ready with reverse and port turn - otherwise the stern of the boat is going to blow off from the dock.
Given the conditions, I think last year's docking went pretty decent. No boats were dinged up, no one was hurt. But, you could see each boat doing nearly the same thing, with power off or very low and the current taking the stern of the boat away from the dock.
Knowing what to expect ahead of time will certainly help.
Have fun!
