Floating Docks without finger
I need to know how high that floating dock is relevant to your bow or stern.
While a gang plank may be the answer it can''t have too steep a grade.
Assuming that your bow is 4 1/2'' high and the dock is 18" thats a 3 foot drop. So consider making a dock box with a few steps. The plank can go from the bow where you can hold onto the forestay.
