nothing to do with me, I just like some of the designs.
They no longer have the plans for the MiniCup on Stevenson Projects?
--------
I'll confess, didn't go to the site. I googled "minicup
plans"http://www.stevproj.com/FastSailrs.html
I'd sorta like to build an updated version of the "PlyFlyer using
stitch and glue. My reasoning is that the MiniCup is too small to
achieve maximum advantage of going from the older methods to stitch
and glue whereas the slightly bigger PlyFlyer built as stitch and glue
could end up much lighter.

Looks like a good project. When I get all my other stuff caught I'd like
to
build a nesting dinghy, you did this right? Like the result?
Well, I do like the result but it has problems. *It fits on the
foredeck of my 28' sailboat but it catches the jib sheets when I
tack. *This has nearly caused serious problems and I cannot figure a
way to completely prevent it. *After going forward in nasty stuff a
couple times o free the jib sheet, I am going to replace the nesting
dinghy. *It woukld do very well on a larger boat where it sat back far
enough to be out of the way. *I do have some suggestions on how o get
the two halves to join in a structurally sound way. *It took me three
tries to get it to work.

Mind sharing your suggestions? I'll file this for when I'm reaady.
Instead of using bolts to secure the two halves as some nesting dinghy
plans do, buy stainless Draw clamps from McMaster Carr and put them on
the outside of the two halves near the gunnel. You will still need
some way to join the two halves near the bottom. I used a stainless L
bracket where the L from the back half slides into a recessed
receiver on the front half.
To have to place the draw clamps carefully, otherwise the two halves
will not nest.
I considered using slide nuts on bolts to join the two halves. These
are nuts that slide almost all the way on when squeezed and then you
tighten them. This would save a lot of time over the original design
using just wing nuts but it still requires a wrench to loosen them AND
you still have the holes to let water in.
My nesting 2-Paw-9 is a really good boat but is still too big for my
28' sailboat foredeck. I also used closed cell foam attached to the
bulkhead between the two halves as floatation. It is attached using
Liquid Nails to the INSIDE of the bulkhead where it will be under the
seat. I also reinforced the seat edges with glass where the edge
holds the two halves together.
Another thing I did to make in-water assembly easier are two pieces of
ply with V cuts in them. While sitting in the back half in the water
facing the bulkhead and the front half floating bulkhead toward you,
pull back half toward you and put the V down over the two halves of
the bulkhead to hold them together while you use the L bracket to
attach front half at bottom and then use the draw clamps to secure
them at the top.
You may be able to forego the draw clamps if your seat has a slot that
securely holds the two halves at the top of the bulkhead.
My instructions said to use a 3/4" piece of wood bent around the
gunnel to reinforce it. MY wood would not bend that much so I
laminated it with 1/4" pieces epoxied and glassed over.
I also laminated the keel and obtained a 1/8" X 3/4" piece of aluminum
stock from Home Depot and used it on the bottom of the keel to keep it
from getting destroyed on rocks and oyster bars. Fasten it with ss
screws.
