I'd like to see a little wooden dock for tying up your rowboat. It could be built either on the edge of the water or into the water. And if your boat is touching a dock and you click on leave... you come ashore onto the dock instead of making half a dozen attempts where the EI thinks you want to leap into the one spot of deep water touching your boat and won't let you. This would also make it much easier for passengers to disembark.
And for added joy, make a way of tying up your boat at a dock so it is harder to steal.
