Was just there - there are TWO types of boats that dock at WL.
The "smaller" boats (the same type that services the GF/Poly to MK run) also runs WL to FW. Those boats are NOT handicapped accessible.
The "larger" boats service the runs to/from CR & MK and the WL dock. Those boats do not have a ramp, but can be accessible - provided that the lake levels are not too high or too low... and they can "balance" the boat to get a (relatively) level opening for the device.
