My guess is that there is still a boat that goes WL-FW-CR. The watercraft map for OKW, SSR, PO is a little confusing as well since none of the boats go to all three locations. SSR-DS, OKW-DS, PO-DS and the boat launch area from DS is in a different location than is shown on this map. Likewise the map for the boats between EP and DHW go in a loop that reverses on the way back from the destination. Not really a very good map.
