Mississippi River Skiff update:

We just glassed the MRS.  After a final fairing and sanding, we glassed the hull with 9oz glass cloth set in low viscosity Raka epoxy with a slow hardener.  This gave us plenty of time to roll out all the wrinkles with a ridged roller.
After three hours we gave it a thin fill coat to fill in the weave.  After another three hours had passed, the surface was slightly tacky and we rolled out the pre cut Kevlar for the bottom.  This received the same epoxy treatment.  It was then three am. so we called it a night.
9oz cloth, originally 50 inches wide, cut down to overlap on the centerline.

The skeg has a 3/4 inch fillet for strength and to ease the layup.  The glass laps in both directions.

The Kevlar bottom will allow for some rough landings.

Mmmm, smells like Walnut ! and the MRS transom

Today I visited Lumber John to get some Ash for the missing oar as well as some Hickory for a non-boat job, and dang it all, he had a beautiful stack of fresh cut Walnut.
Walnut has a weird smell that might be a hallucinogen. Before I realized it, I had a pile of it in my truck.



Here is the transom after it is cut to size.  The sculling hole is marked and faintly visible.  It is a doweled glue up of inch thick cherry.  The sculling hole is offset to starboard to allow for a motor.  The transom is not curvy, but I think it looks nice.


Here is a boatload of hardwood that's too heavy for building boats, but it will make some nice trim pieces.

Mississippi River Skiff update:
The boat is formed.  The glass and one set of oar locks arrived.  The hull will have a laminate of 9 oz glass with Kevlar below the waterline.  The interior will have 6 oz glass all set in Raka epoxy.  http://www.raka.com/    The transom will be installed tonight.
