Mississippi River Skiff construction


Since the bottom of the Mississippi river skiff is "flat"  (it bends through only one plane,) is was super fast to finish.
Because of this we could use wide planks. The planks are 4.5 inch wide ship lapped cedar planks.
They are 5/8ths thick. We started with the bottom and are working down to the gunnels.
After the new poplar had thoroughly dried we planed the strips down to 3/8ths of an inch thick and started the hull's sides.  Working down on the form is different.  It is the opposite of our past projects but for this boat it is working well.
We are using edge clamps to press the strips together and additional clamps to keep the strips tight to the form.  The size of the boat meant it was going to require a trailer from the start.  This lessened the weight considerations and freed up up our choice of materials and thicknesses.  The transom is an attractive shape and we are going to cut it out of a cherry glue up.  It will be an inch thick.
The first hull we build will be set up as a row boat with two stations per the plans.  But the transom will be engineered to take the stress of an outboard.  This is always wanted around here. 
A sail version could be next.


A plumb bob is used to make sure the bow is not pushed out of alignment as the sides are built.
The bob is about 150 years old, and it still works!
