The stealth boat

I have been cheering up the 'teach yourself boat-building boat' which looked rather sorry for itself in comparison to the double.
The boat is built from plans for the Chesapeake 16 LT (Light Tourer) from Fyne Boat Kits, very cheap ply, and various scraps of wood that were laying around.
After the first round of construction it looked like this.
Once Catherine paddled it on a reasonable trip (20k), it deserved a make-over, and now looks a little better, if somewhat fishy. Note the sophisticated deck hatch made from a BDH bottle embedded in foam, improved cockpit rim, footrests, etc.





The question now is - what to build next?
and who for?
